IBL-26-1602Context-Aware Motion Generation Technology Based on Text and Emotion Embeddings
Context-Aware Motion Generation Technology Using Text and Emotion Embeddings

This technology generates motion sequences with emotional context by vectorizing text prompts and emotional information into separate embeddings, then applying the emotion embedding as a condition within a generative AI model.

Existing text-based motion generation often struggles to capture the nuances or intensity of emotions, making it difficult to differentiate the same action based on the underlying emotional state.

By controlling the diffusion process with emotion embeddings and weights, and adjusting facial, hand, and body movements accordingly, this technology enables the creation of expressive, context-aware motions for 3D character content.

‍

‍

Key Features:
  • A processor and memory that receive input information, including text prompts for character actions and the specific emotions to be conveyed.
  • Text embeddings generated from prompts and emotion embeddings that determine the nuance of the motion.
  • A generative AI model that creates motion sequences based on text embeddings while incorporating emotion embeddings as a condition to provide emotional context.
  • Emotion weights that adjust based on the intensity of the emotional information, applied to the diffusion process or attention mechanism to vary the depth of emotional expression.

IBL-26-16013D Character Motion Generation Technology Based on Biomechanical Joint Data and Rotation Constraints
3D Character Motion Generation Technology Incorporating Biomechanical Joint Data and Rotation Constraints

This technology generates 3D character motions by creating a biomechanical context vector—which includes allowable rotation ranges for each joint—from text condition vectors and skeleton structure information, and then applying this to a diffusion-based motion generation model to produce joint-specific rotation sequences.

When generating 3D character motions using AI, issues often arise where joints bend or twist beyond the natural range of human motion, resulting in biomechanically unnatural movements.

By adjusting scale and shift using the biomechanical context vector and replacing or correcting values that exceed allowable rotation ranges with minimum and maximum rotation angles for each axis, this technology enables the generation of biomechanically natural motions for 3D character animation.

‍

‍

Key Features:
  • Generating text condition vectors and acquiring skeleton configuration parameters by inputting text prompts into a text encoder.
  • Generating a biomechanical context vector that includes allowable rotation ranges, joint types, and bone lengths for each joint by inputting skeleton structure information into a biomechanical encoder.
  • Generating joint-specific rotation sequences by inputting the text condition vector and the biomechanical context vector into a diffusion-based motion generation model.
  • Correcting rotation sequences by replacing any joint rotation values that exceed the allowable range with the minimum or maximum rotation angle for that specific axis.

IBL-26-1600Hierarchical Diffusion-Based Text-to-Humanoid Motion Generation Technology
Text-to-Humanoid Motion Generation Technology Combining Hierarchical Diffusion Models and Physics-Based Correction

This technology automatically generates humanoid motion from text by extracting and decomposing verbs into behavioral units, generating motion via conditional diffusion models, stitching segments using overlapping interpolation, and integrating physics-based correction into the reverse diffusion process.

Existing text-to-humanoid motion generation methods often produce unnatural results, struggling with seamless transitions between movements and failing to account for physical constraints such as joint range of motion and foot contact.

By utilizing behavioral decomposition, conditional diffusion models, overlapping interpolation, and integrated physics correction, this technology enables the automatic generation of realistic motion from text alone, making it ideal for 3D character and humanoid content production.

‍

‍

Key Features:
  • A user terminal that accepts text input and outputs a 3D humanoid object performing the motion described in the text.
  • A behavioral decomposition unit that extracts verbs from the text, breaks them down into behavioral units, and infers the sequence and timing of the actions.
  • A motion generation unit that calls a pre-built conditional diffusion model to generate motion corresponding to each behavioral unit.
  • A stitching unit that joins motion segments using overlapping interpolation, and a physics-based correction unit that integrates constraints such as joint range of motion, velocity, and foot contact into the reverse diffusion process.

IBL-26-1599Concrete reinforcement method using curved FRP reinforcements and inserts
Concrete reinforcement method using curved-groove FRP panels wedge-fixed to convex inserts to prevent splitting failure

This technology is a concrete reinforcement method that uses plate-type curved FRP reinforcements with curved grooves on the sides and inserts with matching convex parts. The inserts are first fixed to the concrete structure, and then the grooves of the FRP reinforcement are seated and attached.

When reinforcing aging or poorly constructed concrete structures or buildings built before updated seismic design standards, FRP reinforcement members were typically attached to the surface and secured at the ends with fasteners, bolts, or rivets, or anchored by drilling directly into the members. However, drilling into FRP is difficult, and when external forces are applied, high bearing stress between the fasteners and the holes causes brittle splitting failure of the FRP reinforcement.

This technology features expansion wings protruding from the opposite side of the insert, which is embedded into the structure by cutting installation grooves for the reinforcement and fixing grooves for the wings. The reinforcement can have alternating side grooves, thickened edges, or longitudinal surface grooves. The insert is further secured with anchor holes or embedded resistors, and the installation groove ends are covered. Applicable to seismic retrofitting of schools, flexural reinforcement of bridge decks and parking slabs, and repair of tunnels and underground structures, it eliminates the need for drilling, using the wedge action of the curved grooves to evenly distribute stress and ensure full reinforcement effectiveness without anchorage failure.

‍

‍

Key Features:
  • Preparing a plate-shaped curved FRP reinforcement and an insert with a convex part corresponding to the reinforcement's groove
  • Securing the insert by seating its protruding expansion wings into the corresponding fixing grooves on the structure's surface
  • Forming an installation groove on the concrete structure surface corresponding to the width, length, and thickness of the FRP reinforcement
  • Positioning the curved FRP reinforcement so its grooves seat into the inserts to attach it to the concrete structure

IBL-26-1598Building system including end-block integrated H-beam girders and omega (Ω)-shaped truss girders
Long-span structural system combining end-block H-beam girders with corrugated steel plate omega truss girder decks

This technology is a building system where H-beam girders with integrated end blocks are mounted onto PC columns featuring protruding compression blocks and secured with fastening devices. The floor is then constructed by placing steel decks, consisting of corrugated steel plates and omega (Ω)-shaped truss girders, onto the top flanges.

Hybrid moment-resisting frame structures mixing PC columns and H-beam girders have historically faced challenges in ensuring performance and construction efficiency due to complex joints between dissimilar materials. Furthermore, using H-beams with a uniform cross-section across the entire length—based on the high negative moment at the ends—has been inefficient. Additionally, conventional corrugated or truss decks used for floor slabs have limited rigidity, making them unsuitable for long-span applications.

This technology features a pair of continuously corrugated lattice members inserted into the trough of a corrugated steel plate between two crests. The lower fixing parts are bent outward and the upper support parts inward to join together, with longitudinal top and bottom reinforcement bars creating an Ω-shaped truss. The crest tops feature stiffened grooves filled with compression material, corners have fastening grooves for the lower fixing parts, and both ends include haunches, with compression and end blocks made of UHPC. Suitable for logistics centers, large factories, gyms, and exhibition halls requiring wide, column-free spaces, it increases deck rigidity to allow for shoring-free long-span slab casting and simplifies column-beam connections through dry assembly.

‍

‍

Key Features:
  • PC column including a rectangular concrete column body and compression blocks protruding outward to support the girders
  • Fastening device that passes through the upper part of the neutral axis of the end block cross-section to join the PC column and the end-block integrated H-beam girder
  • Steel deck including corrugated steel plates with troughs formed between two crests and omega-shaped truss girders mounted on the top flange
  • A pair of lattice members continuously bent in a uniform wave pattern, with lower fixing parts bent outward and upper support parts bent inward to be joined together

IBL-26-1597Building system and construction method for connecting square steel pipe columns and end-block integrated H-beams using a weldless external diaphragm
Steel pipe column connection implementing a weldless external diaphragm using inclined plate end-casing interlocking and tensioned steel rods

This technology is a building system for square steel pipe columns equipped with beam support brackets and through-pipes. It involves placing H-beam sections with concrete-filled end casings at both ends onto the brackets, then tensioning and anchoring a fastening device through the pipes to create a rigid connection. The end casing consists of an outer end plate, an inner end plate, side plates, and inclined plates.

Among diaphragms connecting concrete-filled square steel pipe columns and H-beams, internal diaphragms are difficult to fabricate due to the need for welding inside the pipe. Through-diaphragms often create voids inside the pipe, reducing the reliability of concrete filling. While external diaphragms offer better filling reliability, they also require inefficient on-site welding, making quality control difficult. Additionally, using H-beams with the same cross-section throughout their entire length is inefficient.

This technology allows the inclined plates of end casings on beams attached to two orthogonal sides of a column to make surface contact, enabling the casings surrounding the column to act as an external diaphragm without welding. For square columns, the outer end plate and inclined plate form a 135° angle, and adjacent casings are joined with coupling members. Construction involves placing the beam on the bracket, anchoring the steel rods, pouring concrete into the column and casing, and then installing the steel deck and floor slab. Applicable to CFT column frames for high-rise offices, mixed-use complexes, data centers, and large retail facilities, it reduces the need for on-site weld inspections, ensures internal column filling quality, and saves steel by reinforcing only the beam ends.

‍

‍

Key Features:
  • A square steel pipe column including a hollow square cross-section column body, externally protruding beam support brackets, and column through-pipes
  • An end casing coupled to both ends of an H-beam body, containing embedded through-pipes and filled with concrete
  • A fastening device that passes through the column through-pipes and end casing through-pipes, tensioned and anchored to rigidly connect the column and beam
  • An inclined plate extending at an angle from the side plate to connect to the outer end plate, allowing surface contact between the inclined plates of adjacent orthogonal beams

IBL-26-1596Timber wall module with shear-deforming joints
Timber wall module with shear-deforming joints at column ends and split panels for seismic energy absorption

This technology is a factory-produced timber wall module consisting of a frame made of horizontal base plates, vertical columns, top plates, and studs, with panels split into upper and lower sections by horizontal cut lines attached to the front and back. The top and bottom of the vertical columns are connected to the horizontal plates via shear-deforming joints.

Traditional timber shear walls are built on-site by nailing wood and panels together, leading to significant quality variations based on worker skill and long construction times. While factory-produced modules and prefabricated shear wall connection structures have been proposed, there has been a lack of technical solutions that induce ductile deformation in the wall to absorb seismic energy during an earthquake.

This technology utilizes shaft-type shear connectors with reduced-section shear deformation parts at the base, or box-type shear connectors with opening boxes and anchor bolts. The upper joints feature U-shaped shear connectors with hollow shafts containing notched slits, all made of plastically deformable metal. Multiple slits are cut into the top and bottom of the panels to increase horizontal displacement, while ledges on the front and back of the columns and studs resist horizontal movement. Applicable to timber homes, small multi-unit housing, schools, community facilities, and prefab modular construction, this system concentrates seismic damage into replaceable metal joints to protect the wall structure, allowing for the installation of seismic walls simply by assembling modules on-site.

‍

‍

Key Features:
  • A lower horizontal plate made of timber installed on the foundation, with multiple vertical columns erected at regular intervals
  • Timber studs placed between adjacent vertical columns, with their lower ends connected to the lower horizontal plate and upper ends to the top plate
  • Upper and lower panels fixed to the front and back of adjacent vertical columns, split into two by a horizontal cut line to increase horizontal displacement
  • Upper and lower shear-deforming joints that connect the top and bottom of the vertical columns to the horizontal plates, inducing shear deformation in response to horizontal seismic forces

IBL-26-1594Building system connecting columns and girders using compression blocks and fastening devices
Hybrid rigid-frame structure using UHPC compression blocks and fastening devices for dry-joint connection of PC columns and H-beam girders

This technology is a building system that connects H-beam girders, equipped with end blocks at both sides, to PC columns featuring protruding compression blocks. The girder is mounted by inserting the compression block into the block slot at the bottom of the end block, then secured by a fastening device that passes through the neutral axis to tighten the column and girder together. Both the compression blocks and end blocks are made of UHPC.

While hybrid rigid-frame structures using concrete PC columns and steel H-beams are economical, they have historically faced challenges regarding complex joint structures, performance reliability, and construction difficulty. Furthermore, using a uniform H-beam cross-section across the entire span is inefficient, as the section is typically determined by end negative moments. Additionally, the lack of composite action between the H-beam and the cast-in-place slab concrete often leads to stress separation.

In this system, the UHPC compression block handles lower compressive forces, while the upper tensile forces are managed by a fastening device consisting of steel rods, anchor plates, and nuts passing through pipes in the column and end block. A pair of L-shaped steel stiffeners is placed on the top flange to reinforce the positive and negative moment sections, with concrete filled between them to integrate the beam with the slab through holes in the vertical side plates. Suitable for logistics centers, factories, parking structures, and office buildings, this method enables rigid connections via bolting without field welding, while reducing steel usage through end-section reinforcement.

‍

‍

Key Features:
  • A PC column comprising a square concrete column body and externally protruding compression blocks for mounting girders
  • An end-block-integrated H-beam girder with block slots at both ends of the H-beam body, designed to be mounted onto the compression blocks
  • A fastening device that passes through the upper part of the neutral axis of the end block to connect the PC column and the end-block-integrated H-beam girder
  • Central and end compression stiffeners positioned on the top flange in the positive and negative moment sections, respectively

IBL-26-1593On-site assembly-based concrete box girder assembly, structures using the same, and construction method thereof
Box girder for non-cast-in-place curved bridges, assembled by connecting vertically split PSC girders with through-tensioning members

This technology is an assembly that joins factory-produced upper and lower concrete box girders on-site to form a closed cross-section. The girders are first temporarily connected, then integrated by inserting and anchoring connecting members through holes that penetrate from the top surface of the upper girder to the bottom surface of the lower girder.

Urban bridges often feature sharp curves due to space constraints, leading to the frequent use of steel box girders, which are easier to shape but involve high initial costs and ongoing maintenance. Modular methods using precast concrete still require on-site casting, causing traffic congestion, dust, and noise, and are typically limited to long-span bridges, making them difficult to apply to bridges with small radii of curvature.

This technology uses the contact surfaces of the side plates of an upper girder (with deck and flange) and a lower girder (with bottom plate) as split planes. It uses screw sockets in the side plate grooves to temporarily connect the girders with steel plates, then inserts and tensions tendons through first and second through-holes. The PSC girders can be curved longitudinally, and assemblies are joined by tensioning prestressed joints in longitudinal connection holes. Suitable for sharp-curve urban ramps, interchanges, elevated roads with traffic restrictions, and light rail structures, it enables DfMA-based construction without on-site casting, reducing construction time and lowering costs compared to steel box girders.

‍

‍

Key Features:
  • Upper and lower girders that form a closed box-shaped cross-section after assembly and are divided into upper and lower parts via split planes
  • A connecting member inserted and anchored into a through-hole extending from the top surface of the upper girder to the bottom surface of the lower girder to join the two
  • A primary connection means for temporarily joining the upper and lower girders before the final connection by the connecting member
  • A primary connection member consisting of a steel plate fixed to screw sockets in the side plate grooves using fasteners to temporarily join the two girders

IBL-26-1592Groundwater treatment and contamination prevention system
Groundwater remediation system creating a hydraulic barrier using extraction wells with replaceable filters and auxiliary wells with different reactivity

This technology is a groundwater treatment and contamination prevention system that draws contaminated groundwater into a hollow extraction well installed vertically underground, purifies it using a replaceable filter unit, and discharges the treated water through a spaced-apart injection well to form a hydraulic barrier between the two wells. Auxiliary wells aligned with the extraction well are also filled with auxiliary filter units to extend the purification zone.

Permeable reactive barriers containing reactive media have been used for groundwater remediation, but because they require large-scale excavation, they suffer from low efficiency, difficulty in replacing media when contaminants change, and high costs. Furthermore, these barriers can cause groundwater to bypass the system or reduce permeability, and a single barrier is often limited in its ability to treat multiple types of contaminants simultaneously.

This technology features a first auxiliary well downstream equipped with extraction capabilities and a reactive filter similar to the extraction well, and a second non-extraction auxiliary well with a different reactive filter placed in between to filter out different contaminants in stages. The filter unit can be configured with first and second reactive material filters arranged vertically, and the well array can be placed perpendicular or at an angle to the groundwater flow to create linear or parabolic barriers. A water treatment monitoring unit compares the contamination levels of influent and effluent. Applicable to industrial site restoration, groundwater protection around landfills and oil storage facilities, and securing water in rural areas, it allows for responding to changes in contamination by simply replacing filters within the wells without excavation, effectively blocking the downstream spread of contaminant plumes.

‍

‍

Key Features:
  • A hollow extraction well installed vertically underground with an inlet hole at the bottom for contaminated groundwater to enter
  • A filter unit installed replaceably within the extraction well to receive and purify the contaminated groundwater
  • An injection well spaced apart from the extraction well, installed vertically underground, which receives the purified groundwater from the filter unit and discharges it externally
  • A first auxiliary well aligned and spaced apart from the extraction well, located downstream of the groundwater flow, equipped with extraction functions and a reactive filter identical to that of the extraction well

‍

This invention was developed with support from the Ministry of Environment for the development of reactive media for controlling the spread of inorganic contaminants and the development of construction/control technologies for contamination prevention facilities.

IBL-26-1591Wheel and Track Hybrid Mobile Platform Device for Professional Service Robots with Terrain-Traversing Mechanism
Wheel and Track Hybrid Mobile Platform Device for Professional Service Robots with Terrain-Traversing Mechanism

This technology is a hybrid mobile platform mechanism that combines driving wheels with track modules. By adjusting the angle of the track arms via motor power, the structure can be varied to ensure wheel contact on flat surfaces and track contact with the ground on rough terrain.

Conventional wheeled robots excel on flat surfaces but struggle with rough terrain and stairs. Tracked robots are advantageous for rough terrain but suffer from lower speed and energy efficiency on flat surfaces, while legged robots face challenges with complex control and stability.

This technology features a track transformation mechanism that adjusts the position of the track arms using a motor. On flat ground, the track arms are kept horizontal for wheel-based driving, while on rough terrain or stairs, the arms are raised to bring the tracks into contact with the ground, optimizing the driving mode. Applicable to logistics, service robots, and autonomous platforms, it enhances the adaptability and stability of specialized service robots on uneven terrain, thereby improving overall performance and energy efficiency.

‍

‍

Key Features:
  • A control device that manages the motor unit to move multiple track arms into a vertical position during rough terrain traversal, transforming the track so that its vertical width exceeds the circumference of the driving wheels.
  • A wheel and track hybrid mobile platform device for professional service robots with a terrain-traversing mechanism, characterized by multiple driving wheels retracting inside the tracks to enable track-based movement during rough terrain traversal.
  • Multiple track arms that move into a horizontal, lying-down position to transform the track so that its vertical width is smaller than the circumference of the driving wheels.
  • A main frame for a wheel and track hybrid mobile platform device for professional service robots with a terrain-traversing mechanism.

IBL-26-1589Noise-Reducing, Ultra-Lightweight, High-Strength Concrete Formwork Frame
Lightweight and quiet formwork frame featuring an integrated TWIP steel inner frame filled with sound-absorbing material

This technology is a concrete formwork frame in which a hollow, integrated inner frame with open bottom and ends is formed from TWIP steel inside a rectangular outer frame, then connected using corner and inner brackets. Sound-absorbing material is filled inside the inner frame, and panels are attached by interlocking the panel grooves with the fitting section at the bottom of the outer frame.

Wooden formwork frames lack durability for repeated use, while steel frames are sturdy but heavy, reducing work efficiency. Aluminum frames, which were developed to address these issues, are lightweight but noisy, expensive, and produce five times more CO2 during manufacturing than steel. Furthermore, because their inner and outer frames are welded, they are prone to damage or warping from impact if dropped during form removal.

This technology uses a pair of ultra-high-strength or TWIP steel inner brackets inserted into the ends of the inner frame, with their tips bent outward to fasten to the outer frame. It prevents detachment through the interlocking of a stepped press-fit anti-detachment section and a detent. Silicone sealant is applied to the fitting surfaces, and steel wedge cores are inserted into the wedge pin holes to prevent wear from repeated use. Suitable for wall and slab formwork in apartment and office construction, high-reuse system formwork, and urban sites sensitive to noise, this lightweight, weld-free steel frame reduces both impact noise and damage from drops during form removal.

‍

‍

Key Features:
  • A rectangular outer frame consisting of a pair of first outer frame members and a pair of second outer frame members positioned at both ends
  • An integrated inner frame with a hollow structure open at the bottom and ends, where the first and second integrated inner frame members are formed as a single piece of TWIP steel and filled with sound-absorbing material
  • Inner brackets made of ultra-high-strength or TWIP steel, inserted into the ends of the integrated inner frame with tips bent outward to fasten to the outer frame
  • An anti-detachment section press-fitted into the ends of the integrated inner frame with a step, where the outer detent engages with the corresponding detent in the inner bracket groove

IBL-26-1588Storm drain with blockage detection functionality
Self-powered storm drain that detects blockages via optical illuminance sensors, transmits identification signals, and performs reverse-air cleaning.

This technology features a storm drain with multiple optical sensors installed on the upper filter screen connected to underground sewer pipes. If the illuminance drops below a set threshold on a majority of the sensors, the processor identifies the screen as blocked and transmits a blockage signal containing the drain's identification information to a central system.

Storm drain screens are frequently blocked by accumulated leaves and debris, or covered with rubber mats to prevent odors, which hinders rainwater drainage and often leads to flooding. Previously, maintenance required manual, on-site visual inspections, making it difficult to identify and address blocked drains in a timely manner due to labor shortages.

This technology incorporates a solar power generator on the main unit and a blower between the filter screen and the generator. When low illuminance suggests a blockage, the blower reverses to blow air toward the screen, clearing debris. Once illuminance returns to normal, it rotates forward to cool the generator and clear dust. A weight sensor on the inner support protrusions verifies the screen's weight, ensuring signals are sent only when both illuminance and weight thresholds are met, thereby reducing false alarms from shadows or temporary obstructions. Generated power is stored in a battery. Applicable to municipal road drainage, commercial back alleys, and flood-prone underpass entrances, this system allows managers to identify blocked drains on a map and dispatch cleaning crews directly to specific locations without pre-monsoon patrols.

‍

‍

Key Features:
  • A main unit buried underground that collects rainwater through an upper opening and connects to sewer pipes, and a filter screen that filters rainwater at the top.
  • Multiple optical sensors installed on the filter screen to measure external illuminance, and storage for drain identification information.
  • A processor that transmits a filter blockage signal, including identification information, to a central system when a majority of the optical sensors detect illuminance below a first threshold.
  • A blower positioned between the filter screen and the solar generator that provides air to the generator when rotating forward and to the filter screen when rotating in reverse.

IBL-26-1587Steel pipe with carbon fiber reinforced plastic internal reinforcement structure
Internal reinforcement of pedestrian bridges using a jack-up tensioner to push carbon fiber plates against steel pipes, applying compressive force

This technology features an internally reinforced steel pipe structure where clamps are installed at both ends inside the pipe to secure the plate ends. A tensioner fixed to the bottom interior of the pipe pushes the plate upward, applying tension that pulls the pipe toward the center, thereby exerting compressive force.

Pedestrian bridges are smaller and lighter than road bridges, requiring sufficient rigidity for user safety and protection against dead loads, live loads, seismic activity, and deflection due to strength degradation. Existing methods using internal cross-bracing often involve concrete, which increases weight and leads to strength loss if the reinforcement corrodes. Similarly, external steel girder reinforcement systems add weight and are prone to corrosion.

This technology features a tensioner divided into a fixed base and a vertically moving part, allowing for easy tension adjustment by locking the moving part at the desired height with bolts and nuts. The contact point on the moving part prevents plate slippage. The clamp body, designed with the same curvature as the steel pipe, is screw-fastened to the interior, securing the carbon fiber reinforced plastic (CFRP) plate. A saddle roller redirects the plate, while auxiliary reinforcement members—comprising inner/outer loops and diagonal/vertical frames—support vulnerable areas. Applicable to landmark pedestrian bridges, river-crossing bike paths, and aging girder repairs, this system adds minimal weight, resists corrosion, and allows for tension recovery by simply tightening the bolts if the structure loosens over time.

‍

‍

Key Features:
  • A clamp installed at both ends of the steel pipe, securing the plate ends between a clamp body and a friction body
  • A carbon fiber reinforced plastic plate secured to the clamps, providing compressive force to the steel pipe through tension
  • A tensioner with a fixed base attached to the bottom interior of the pipe and a moving part that adjusts vertically to contact the plate
  • A clamp body with a top curvature matching the steel pipe and wing-shaped fixing parts that are screw-fastened to the pipe

‍

This invention was developed with support from the Ministry of Land, Infrastructure and Transport for the development of carbon-polymer corrosion-zero reinforcement alternatives.

IBL-26-1586IoT Smart Storm Drain and System Including the Same
Solar-powered IoT storm drain that clears debris by tilting a collection mesh via wire winding on sunny days

This technology is an IoT smart storm drain that divides the interior into a rainwater permeable section and a debris storage section. A primary debris collection mesh, installed at an angle in the permeable section, filters out debris while allowing rainwater to pass through; it then rotates to dump the collected debris into the storage section. A wire is connected to the high end of the mesh, a rotating shaft to the low end, and a winding motor pulls the wire to actuate the mesh.

Conventional storm drains often become clogged with leaves and trash, or are covered with rubber mats to block odors and pests, preventing proper drainage and leading to flooding. Periodic maintenance is essential to prevent this, but current manual inspection methods are limited by labor shortages.

This technology uses a rainwater sensor on the upper body to keep the mesh tilted during rain for optimal drainage. Once the rain stops, a motor controller activates the winding motor to rotate the mesh and dump debris into the storage area. A secondary mesh below the rotating shaft provides additional filtration. Debris level sensors send data to a control server and then to operator devices. A solar panel and secondary battery provide power, while an LED block marks the curb for pedestrians. Ideal for urban roads, flood-prone lowlands, and tree-lined streets, it keeps drains clear automatically, requiring manual collection only when the storage bin is full.

‍

‍

Key Features:
  • A primary debris collection mesh installed at an angle in the rainwater permeable section to filter debris while allowing water to pass, and which rotates to transfer debris to the storage section
  • A mesh actuation unit including a wire connected to the high end of the primary mesh and a rotating shaft connected to the low end
  • A winding shaft connected to the other end of the wire, a winding motor to rotate the shaft, and a motor controller to manage its operation
  • A control unit that regulates the rotation of the primary debris collection mesh by managing the mesh actuation unit
