Load distribution system and load adjustment device

Manual load adjustment device that distributes load through wire friction and gear gap control

This technology is a manual mechanical device that distributes load using wire friction. It features a kinematic mechanism that controls the wire's locked or released state by adjusting the gap between the first and second gears through the rotation of an engagement adjustment member.

Repetitive lifting of heavy objects causes muscle fatigue and injury risks. Existing motorized assistive devices are heavy and expensive due to the need for motors, controllers, and power supplies.

This technology implements a manual load adjustment device that physically supports the load by securing or releasing the wire through grooves (receptacles) formed in the teeth of the first and second gears, without the need for a motor or other power sources. It can be applied to industrial muscle assistance, logistics, and rehabilitation, reducing muscle fatigue and injury risks by assisting with heavy object handling without the need for motorized equipment.

Key Features:

• A body providing an internal space by having opposing inner surfaces spaced apart by a set distance
• A first gear rotatably provided in the space formed between the inner surfaces of the body
• An engagement adjustment member rotatably provided based on an adjustment rotation axis, which changes the axial position of the second gear according to its rotation
• A second gear connected to the engagement adjustment member, which engages with or disengages from the first gear and features groove-shaped receptacles formed in its teeth

This invention was developed with support from the Ministry of Science, ICT and Future Planning for the development of under-actuated mechanisms and gait control technology for exoskeleton robots, which are modified assistive devices for the independent walking of individuals with paraplegia.
