Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If fixed-size leg grips are used in exosuits, then the structure is simple and easy to manufacture, but the exosuit cannot accommodate varying leg sizes and reduces adaptability
Solution Approach 1:
The leg grip employs an inflatable bladder mechanism that dynamically adjusts its internal volume and pressure to accommodate different leg sizes. The bladder can be inflated or deflated in real-time, transforming the rigid structure into a dynamic, adaptable component that conforms to various leg dimensions without requiring complex mechanical adjustment systems
Solution Approach 2:
The invention changes the physical parameter of the leg grip's internal volume through inflation and deflation of the bladder. By controlling the air pressure and volume within the bladder, the leg grip can expand or contract to fit different leg sizes, providing adaptability through parameter modification rather than structural complexity
2Adaptability or versatility
If adjustable leg grips with inflatable bladders are used, then adaptability to different leg sizes is improved, but the device complexity and manufacturing difficulty increase
Solution Approach 1:
The leg grip utilizes pneumatic inflation through a bladder system that can be filled or emptied with air. This pneumatic mechanism provides a simple yet effective way to adjust the leg grip size, avoiding complex mechanical assemblies while maintaining ease of manufacture through the use of standard inflatable component technology
Solution Approach 2:
The inflatable bladder design serves multiple functions: it provides adaptability to different leg sizes, maintains structural support when inflated, and can be integrated with the exosuit's existing pneumatic or electronic control systems. This multi-functionality reduces the need for separate adjustment mechanisms, thereby simplifying manufacturing
3Adaptability or versatility
If rigid leg grips are used, then structural support is provided, but comfort and adaptability to different leg shapes are reduced
Solution Approach 1:
The leg grip incorporates a flexible bladder made of elastomeric material that can conform to various leg shapes while maintaining structural integrity when pressurized. The flexible shell adapts to the contours of different legs, providing both comfort through conformability and support through pneumatic pressure
Solution Approach 2:
The leg grip structure combines flexible elastomeric bladder material with rigid or semi-rigid external housing or mounting structures. This composite construction allows the internal bladder to conform to leg shapes for comfort and adaptability, while the external structure provides the necessary structural support and attachment points for the exosuit
