This technology is a building envelope insulation system that attaches a case containing phase change materials (PCM) to the building exterior to store and release ambient heat. It features a first thermoelectric module that generates electricity from the temperature difference between the case's outer surface and the ambient air, and a second thermoelectric module that uses voltage to heat or cool the PCM.
Vacuum insulation panels used for building envelopes are thin and highly efficient, but they require professional installation and extreme care because their performance drops sharply if the vacuum is compromised during construction. Furthermore, depending on the installation method, insulation gaps or thermal bridges penetrating the interior and exterior can occur, limiting the overall thermal performance of the structure.
This technology stores power generated by the first thermoelectric module in a battery to drive the second thermoelectric module via a voltage circuit, allowing for PCM regeneration without external power. A temperature sensor monitors the PCM at 70-90% of its thickness, triggering the second module if the temperature deviates by more than ±5°C from the phase change point. It can also include a heat flux processor that calculates heat flow from the first module's voltage to assist HVAC systems, along with heat dissipation fins on the second module. Applicable to zero-energy building facades, high-solar-load curtain wall offices, and building retrofits, it converts solar heat into electricity while monitoring solar loads in real-time to reduce HVAC energy consumption.
This invention was developed with support from the Ministry of Science and ICT’s laboratory research program for harvesting and utilizing unused energy to realize carbon-neutral buildings.
This technology is a rotating shoring head unit that attaches a fixing member to the underside of a table form slab mold using two fixing pins. It allows the shoring to be tilted or set upright while remaining connected to the mold by tilting and rotating the rotating member around the first fixing pin. When the locking protrusion of the rotating member is inserted into one of the various locking grooves around the fixing member, the angle of the shoring is securely locked in place.
Existing table forms used in high-rise reinforced concrete construction have fixed shoring, which requires the length to be adjusted with height-adjustment screws every time they are moved. Furthermore, if there are obstacles indoors, the shoring must be completely disassembled before moving. Recently developed rotating shoring also requires inconvenient additional work, such as installing separate reinforcing bars to set the rotation or fixed positions.
This technology features pin insertion holes in the first and second rotating plates—which face each other with the fixing member in between—that are wider than the pins themselves. This allows the protrusion to disengage from the groove when the plate is tilted and re-engage when it is upright. The second rotating plate includes an arc-shaped window and an indicator with markings, allowing users to see from the outside which locking groove is engaged. A pin-locking part catches on the second fixing pin, stopping the rotation when the shoring is perpendicular to the floor. This can be applied to slab framing for high-rise apartments and offices, RC buildings with repetitive floor modules like hospitals and offices, and dedicated table form lifting systems. It allows the entire mold to be moved without changing the shoring length, reducing construction time and labor per floor.
This invention was developed with support from the Ministry of Land, Infrastructure and Transport for the development of system formwork and lifting technology for low-cost, high-speed construction.
This technology is an architectural structure designed to reduce heavy-weight impact noise by installing L-shaped steel beams between opposing sidewalls beneath the floor slab, allowing the beams to exert an upward force against the underside of the slab.
Impacts from walking or running on a floor cause the slab to vibrate, transmitting noise to the floor below and often leading to disputes between neighbors. While current methods primarily involve installing cushioning materials on the floor surface, the intensity of floor impact noise is largely determined by the vibration characteristics of the slab structure itself, limiting the effectiveness of cushioning alone.
This technology uses steel beams longer than the distance between the sidewalls; when both ends are connected at the same height on the sidewalls, the center arches upward, pressing against the underside of the slab. The ends are connected via hinges, using 4–25mm thick rolled steel cambered beams with a 190–210mm height difference between the center and ends, spaced across the slab width with a natural frequency of 29–32Hz. Applicable to new residential buildings, ceiling reinforcement in existing apartments, and dormitory or office floor structures, it suppresses slab vibration from the ceiling space below without removing floor finishes, effectively reducing heavy-weight impact noise like footsteps.
This technology is a non-automatic sliding door device for a door frame with an opening and storage space. When opening or closing the sliding door, the force applied by the user to the drive mechanism is transmitted to a pinion on a rotating shaft and a rack attached to the door, moving the door horizontally.
Manual sliding doors require significant effort to push or pull by hand, making them inconvenient when your hands are full. While electric doors with sensors and motors solve this, they come with higher installation and maintenance costs, and there has been a lack of specific technology to address the drawbacks of both methods.
This technology features a drive lever on the door frame that moves vertically, supported by a lever base fixed to the floor. When the lever is pressed with a foot, the pinion on the rotating shaft pushes the rack horizontally to open the door. The rack is tilted upward in the opening direction, and a guide roller on the rotating shaft, along with a guide rib that limits its height, ensures the pinion and rack remain engaged. An elastic member connecting the door frame and the door provides constant force in the closing direction to assist with automatic return. It can be applied to hospital and laboratory hygiene zone doors, kitchen and warehouse workspaces where hands are often occupied, and restroom or public facility sliding doors, enabling hygienic access without electricity or sensors by allowing hands-free operation.
This technology is a building reinforcement material where concrete is poured in a fluid state into the casting holes of a Wood Plastic Composite (WPC) frame. Once hardened, the core is bonded to the frame via connecting parts that protrude from the inner surface of the frame toward the center.
While wood is eco-friendly and aesthetically pleasing, it is vulnerable to deforestation issues, pests, fire, and decay. Plastics, conversely, are non-biodegradable and weak against heat and impact. Although Wood Plastic Composites (WPC), which combine the strengths of both materials, are growing in popularity as eco-friendly alternatives, they have limited durability compared to concrete or steel, making them unsuitable for structural members that must bear heavy loads.
This technology features a WPC body with embedded longitudinal carbon fiber reinforcement members. Inside the concrete core, multiple reinforcement members are placed, each consisting of a carbon fiber-reinforced body with a pair of protruding members angled in different directions. The connection consists of a first connecting member perpendicular to the frame's longitudinal axis and a second connecting member that bends into the concrete. After the concrete hardens, epoxy is injected into the gap between the core and the frame to create a unified structure. It can be applied to the reinforcement of wooden cultural heritage sites and Hanok columns and beams, eco-friendly wooden public buildings, and waterfront deck structures, providing the load-bearing capacity of concrete and carbon fiber without the risk of corrosion or decay, while maintaining a natural wood aesthetic.
This invention was developed with support from the Ministry of Land, Infrastructure and Transport for research on simulation analysis and life-cycle economic analysis of rebar-alternative concrete structures.
This technology features a drain cover designed to fit into the guide groove of a bathroom or balcony floor drain. It includes a handle that pivots on a central axis within a portion of the perforated cover, allowing the handle to remain hidden beneath the cover when not in use and emerge when the body is rotated.
Drain covers are typically sized to fit snugly within the guide groove to prevent hair and debris from escaping, which makes them difficult to lift from the floor for cleaning. While some products feature raised grips, these protrusions can create tripping hazards, leading to slips or falls.
This technology features a handle on the side opposite the flat base, with a protruding member that limits the rotation angle and snaps into an elastic insertion groove to secure the handle in both exposed and hidden positions. The body includes secondary drainage holes and a catch protrusion on the handle to further filter debris. The handle, made of an elastic rod-like material, can be detached from the coupling groove and may feature a multi-pronged end. Suitable for residential bathrooms and balconies, hotel bathrooms, and public shower facilities, this design maintains a flat surface to prevent tripping while allowing the cover to be easily lifted for cleaning by simply flipping the handle.
This technology features a guardrail designed with an upper rollover prevention unit that rotates downward upon vehicle impact, and a lower shock-absorbing unit that uses springs to dampen the force. These sections are connected by sacrificial members, allowing the upper and lower parts to move independently.
Conventional guardrails, which use corrugated beams supported by posts, often fail to effectively absorb impact energy, causing vehicles to spin and resulting in severe damage to both the vehicle and its occupants. Even guardrails designed to absorb energy through steel plate deformation or staged dampening struggle to prevent vehicle rotation and rollover during high-impact collisions, leading to secondary accidents.
This technology features a rollover prevention unit that protrudes further outward than the shock-absorbing unit to redirect impact force downward. The post's curved insert fits into the rotation head's groove to act as a pivot, while a stopper prevents upward tilting and a reinforcement member increases structural rigidity. The lower plate's compression section pushes into a spring-loaded cylindrical housing, where viscous fluid further dampens the impact. The plastic sacrificial members connecting the upper and lower plates break upon impact to absorb additional energy and serve as reflective surfaces for headlights during normal operation. Suitable for mountainous roads, highway medians, bridge approaches, and sharp curves, this system prevents vehicles from vaulting over the guardrail and reduces secondary accidents caused by rotation.
This invention was developed with support from the Ministry of Land, Infrastructure and Transport's project for the development of eco-friendly, high-yield recovery and circulation systems for unconventional oil.
This technology is a device where a processor automatically determines road condition information when a road image is input into an AI algorithm stored in memory. The algorithm is trained using virtual road data generated based on actual road measurement data.
With the surge in traffic volume and vehicles, road degradation such as cracks and potholes has become frequent, impacting driver safety and vehicle fuel efficiency, making road condition assessment critical. However, professional equipment for quantitative road evaluation is expensive and not widely used, and even with AI, there has been a limitation in securing enough labeled road images for training.
This technology selects a portion of actual road flatness measurements to calculate sigma values, creates noise data, and passes it through a predetermined transfer function to obtain 2D virtual road information, which is then converted into 3D virtual road data. It expands training data by generating multiple sets of the same road surface with varying light incidence angles. Applicable to routine pavement inspections by road authorities, vehicle-mounted camera-based surface monitoring, and prioritizing pothole repairs, it enables the mass production of training images with automatically labeled flatness levels, allowing for the construction of real-time surface evaluation models without expensive equipment or manual labeling.
This invention was developed with support from the Ministry of Land, Infrastructure and Transport's project for developing non-contact safety diagnosis technology based on unmanned survey vehicles for real-time dynamic bridge behavior prediction.
This technology features a piezoelectric ceramic insert embedded in ground or structures to secure anchor bolts. By injecting electrorheological fluid—which changes viscosity based on the applied electric field—into the space between the insert and the anchor bolt, it actively dampens vibrations according to their intensity.
Inserts and anchors used to secure rails and embedded bolts for subways and maglev trains are subject to repeated, high-intensity vibrations, which can lead to damage or detachment, posing a risk of major accidents. Previous active vibration damping technologies using piezoelectric actuators struggled to control high-intensity vibrations, while damping technologies using viscous fluids faced challenges with vertical or horizontal installation.
This technology utilizes a corrosion-resistant and fire-retardant piezoelectric ceramic insert. Fluid is filled between the case and the threaded connection, with longitudinal guide grooves on the anchor bolt and a serrated gasket facilitating fluid injection and sealing. When the vibration sensor detects low-level vibrations, voltage is applied only to the piezoelectric plate embedded with the insert. If the vibration exceeds a set threshold, voltage is also applied to the anchor coil inside the anchor bolt to increase fluid viscosity for a combined response. Applicable to subway rail fastening systems, maglev guideway embedded bolts, and foundation anchors for vibrating machinery, this system allows the piezoelectric ceramic to handle minor vibrations while the electrorheological fluid manages major ones, effectively reducing loosening and detachment accidents during train operation.
This invention was developed with support from the Ministry of Trade, Industry and Energy for the development of low-heat cement manufacturing and utilization technology that replaces more than 5 wt.% of limestone using non-carbonate raw materials.
This technology is a prefabricated composite floor structure that forms building floors by bolting and connecting multiple floor modules—each consisting of a pair of spaced-apart rectangular steel plates filled with phase change material (PCM) that stores and releases heat at specific temperatures—onto a steel frame.
Most building floors are constructed using wet methods involving formwork installation, concrete pouring, curing, and form removal, which require significant equipment, labor, and skilled workers, leading to longer construction times. Even modular floor assembly methods often include concrete, which increases construction costs when accounting for the module manufacturing process.
This technology features side plates on the modules that protrude beyond the upper steel plate. A connecting bar with a guide slot is inserted through a hole in the bottom of the side plate, and bolts are passed through head insertion holes, slots, and fixing holes to secure the module to the steel frame, with the holes then sealed. A connecting rod is placed across the protruding side plates between adjacent modules, and an elastic synthetic resin sealing member is press-fitted between the rod and the upper steel plate to close the gap. Applicable to steel-frame office and commercial floors, modular homes, and factory or warehouse expansions where rapid construction is required, this system allows for lightweight, fast installation without concrete pouring, while providing thermal insulation and soundproofing through the PCM's heat storage.
This invention was developed with support from the Ministry of Science and ICT for the PCM-filled fire-resistant Hybrid Floor system.
This technology is a soundproof port for aircraft that completely encloses the takeoff and landing space. It features a circular soundproof wall erected around a soundproof floor made of acoustic materials, with curved soundproof doors that slide along a top rail to open and close soundproof openings in the wall.
Existing helipad structures are primarily designed to mitigate fire and crash risks, with little focus on maintaining safe distances between aircraft and passengers or reducing the spread of takeoff and landing noise. Even helidecks equipped with evacuation structures fail to fully enclose the landing zone, leaving issues such as collision risks with passengers, noise pollution, and acoustic loads caused by vibrations transmitted to building rooftops.
This technology absorbs takeoff and landing noise by coating the inner surface of the soundproof wall with acoustic material. A control unit manages the soundproof doors: when the floor's vibration sensors detect a landing and the rail's proximity sensors detect a person, the doors open for access and close again before takeoff. A rail locking mechanism and seals between the doors and walls maintain sound insulation. The floor is made of vibration-damping materials like rubber or urethane, the wall diameter is 24–30m, and lighting is installed along the rail. Applicable to UAM vertiports, rooftop helipads, and hospital emergency helipads, it prevents rotor noise from spreading in residential areas and prevents accidents by ensuring doors only open after the aircraft has come to a complete stop.
This technology is a horizontal mobile unit consisting of first and second horizontal mobile modules, each equipped with a frame and a rail-moving component, connected by a vertical axis to allow for pivoting movement along horizontal rails installed on a building's exterior.
Painting, cleaning, and inspection of skyscrapers have traditionally relied on rope access or gondolas, exposing workers to fall risks from strong winds and gusts, while also resulting in significant variations in quality and cost based on worker skill. Existing exterior wall robots that use suction pads or magnets to adhere to walls require separate safety devices to prevent falls in case of malfunction and struggle to adapt to diverse curtain wall structures.
This technology connects two frames with a hinge and uses a restoring mechanism to straighten the modules, allowing them to travel continuously along curved rail sections. Each module features wheel units and drive components that follow the upper and lower rails, while guide wheels in the rail grooves and damper units between plates prevent derailment and absorb deviations. Applicable to skyscraper cleaning, curved curtain wall painting, and maintenance of non-standard buildings, this system eliminates fall risks from suction failure and enables autonomous operation on curved facades.
This invention was developed with support from the Korea Agency for Infrastructure Technology Advancement for the development of Built-in Guide type mobile/work mechanisms and platforms.
This technology is an architectural exterior material featuring dense, dust-trapping trichome structures on the front of the plates attached to building walls, with a water tank at the top that releases stored water to flow down the plate surface.
Fine dust causes respiratory and cardiovascular diseases. While photocatalytic coatings have been proposed to decompose precursors, their effectiveness drops at night without sunlight, and high material costs have limited their widespread use as building exteriors.
This technology consists of trichome structures with a base attached to the plate and an extension that changes angle based on moisture content, featuring grid-like protrusions on the base and radial ones on the extension, with a diameter of 450–550㎛. The plate is divided into a base section and a pivoting section; when the latter tilts, a top packing unit opens the tank outlet to release water. A control unit can trigger water release based on infrared dust sensors or water levels. Applicable to roadside commercial and office buildings, facades of dust-sensitive facilities like schools and hospitals, and residential buildings near industrial complexes, it filters airborne dust day and night at a low cost and restores collection performance by self-cleaning with rainwater or stored water.
This technology involves recycling waste activated carbon—typically discarded after use in air and water pollutant treatment—by modifying it through immersion in an iron sulfate solution (a cationic additive), then pouring and compacting it into a housing to create paving blocks.
As urbanization increases impermeable surfaces, pollutants accumulated on roads during heavy rainfall flow directly into streams. Furthermore, cement paving blocks prevent rainwater from soaking into the ground, contributing to groundwater depletion and urban flooding. While permeable concrete and blocks have been developed, they are limited to water drainage and fail to filter pollutants from rainwater or mitigate the urban heat island effect by retaining moisture.
This technology involves drying waste activated carbon in an oven, pulverizing it, and using a sieve shaker to isolate 1–5mm particles. After washing with distilled water, drying, and sterilization, the particles are impregnated with a 0.05–0.2M iron sulfate solution to enhance pollutant adsorption. The housing is 3D-printed using biodegradable materials like polylactic acid (PLA), with a 0.5–1mm stainless steel mesh placed at the bottom. Applicable to sidewalks near non-point source pollution discharge points, low-impact development (LID) paving in urban parks and parking lots, and riverside walkways, this method reduces pollutant loads in water systems by adsorbing contaminants as rainwater passes through the blocks, while also contributing to resource circulation by repurposing waste activated carbon as paving material.
This technology is a securing device that prevents cylindrical piles from rolling or shifting during transport by pressing a fixing panel body against the base of an end cap fitted onto the PHC pile and tightening a bolt through the panel into the cap's screw hole.
PHC piles are widely used for pile foundations due to their high-strength concrete, superior load-bearing capacity, and durability. However, their cylindrical shape makes them prone to rotation from vibrations and external forces when stacked on trucks for transport from factories to sites. This often leads to friction, collisions between piles, and impact with the truck bed, resulting in cracks and damage.
This technology features connection protrusions on one side and the top of the panel body, with corresponding connection grooves on the opposite side and bottom, allowing adjacent panels to interlock vertically and horizontally. The panels are made of elastic synthetic resin. A guide-fastening unit, consisting of an elastic guide shaft inserted into the cap's through-hole and a stopper block, provides additional security. Applicable to factory loading, long-distance trailer transport, and on-site storage, this system bundles stacked cylindrical piles together, reducing damage from cracks during transit and preventing rolling accidents during unloading.
This invention was developed with support from the Ministry of Land, Infrastructure and Transport's digital-based construction and safety supervision technology development program.
