Solution Overview
Problem
Existing motion assistance apparatuses for individuals with joint problems or the elderly do not effectively address the need for reduced effort and comfort during walking, often relying on hydraulic systems and driving motors that can be cumbersome and uncomfortable.
Innovation Solution
A supporting module with a frame, connecting plate, sliding plate, and elastic strip system that provides elastic force to assist joint movements, incorporating adjustable bands and shock-absorbing pads for enhanced comfort and flexibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If active joint structures including hydraulic systems and driving motors are used to improve muscular strength, then the supporting force is enhanced, but the device complexity and weight increase
Solution Approach 1:
The patent extracts and removes the complex hydraulic systems and driving motors from the motion assistance apparatus, replacing them with a simplified passive support structure that uses elastic bands and adjustable tensioning mechanisms to provide supporting force without active power systems
Solution Approach 2:
The patent employs simple, lightweight components such as elastic bands, straps, and adjustable connectors that can be easily replaced or adjusted, replacing expensive and complex hydraulic/motor systems with affordable, maintenance-free alternatives
2Force
If active joint structures with hydraulic systems and driving motors are used to improve muscular strength, then the supporting force is enhanced, but the weight of the apparatus increases
Solution Approach 1:
The patent removes heavy hydraulic systems and driving motors from the apparatus, replacing them with lightweight elastic bands, fabric straps, and minimal metal connectors, dramatically reducing the overall weight while maintaining supporting force through passive mechanical advantage
Solution Approach 2:
The patent substitutes heavy durable hydraulic/motor components with lighter, replaceable elastic bands and fabric elements that provide sufficient supporting force for their intended use duration without the weight penalty of industrial-strength active systems
3Force
If a rigid supporting structure is used to provide stable support, then the supporting force is enhanced, but the comfort and adaptability to user motion decrease
Solution Approach 1:
The patent employs flexible elastic bands, fabric straps, and compliant connectors throughout the support structure, allowing the apparatus to conform to and move with the user's body and joint motions while maintaining supporting force, eliminating the discomfort of rigid structures
Solution Approach 2:
The patent creates a dynamic support system where elastic bands and adjustable straps continuously adapt their tension and configuration in response to user motion, maintaining optimal supporting force throughout the range of motion rather than providing fixed rigid support
4Force
If a rigid supporting structure is used to provide stable support, then the supporting force is enhanced, but the adaptability to different users and motions decreases
Solution Approach 1:
The patent implements multiple adjustable elements including telescopic straps, adjustable buckles, and elastic components with varying tension characteristics, allowing the same apparatus to be customized for different user sizes, weights, and motion patterns while maintaining stable supporting force
Solution Approach 2:
The patent uses flexible elastic bands and fabric straps that naturally adapt their shape and tension to accommodate different user anatomies and motion ranges, providing stable support across diverse users without requiring rigid structural adjustments
