Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If conventional battery structures are used in wearable robots, then the device can be assembled, but the mechanical stability and load-bearing capacity are insufficient
Solution Approach 1:
The patent applies composite materials by integrating the battery structure with a structural frame made of high-strength materials. The battery is not merely mounted but structurally coupled with the frame, creating a composite system where the battery case and frame work together to provide enhanced mechanical stability and load-bearing capacity while maintaining weight efficiency for wearable robots
2Quantity of substance
If the battery structure is optimized for high capacity, then energy storage increases, but mechanical stability and load support capability deteriorate
Solution Approach 1:
The patent merges the battery module with the structural frame into an integrated assembly where the battery is not a separate component but part of the load-bearing structure. This merging allows the battery's weight to be structurally utilized, and the frame to provide mechanical support, achieving both high capacity and load support capability simultaneously
3Adaptability or versatility
If the rotation module has various shapes for different applications, then adaptability increases, but torque measurement difficulty increases
Solution Approach 1:
The patent employs a universal torque measurement apparatus that can measure torque for rotation modules of various shapes. The apparatus includes a mounting structure that can accommodate different geometries, and uses a standardized force application mechanism that works regardless of the rotation module's shape, thereby enabling torque measurement across diverse applications without requiring shape-specific measurement solutions
