Prosthetic Limb Function Recording and Usage Analysis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
It is challenging to objectively evaluate the necessary functions of prosthetic limbs and other products with multiple features, making it difficult for users to select the appropriate product and for examination authorities to determine the necessity of these products for funding or insurance purposes.
Innovation Solution
An information recording device that acquires, stores, and outputs usage information for each function of a product, combined with an analysis system that analyzes this data to provide objective and qualitative evidence of the user's needs, facilitating the selection of suitable products and supporting funding applications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple functions are installed in a prosthetic limb, then the quality of life of the user is improved, but the price of the product increases
Solution Approach 1:
The patent segments the prosthetic limb into multiple independent functional units (e.g., knee joint, ankle joint, foot unit) that can be individually selected and configured. Each functional unit can be equipped with or without additional features, allowing users to choose only the functions they need, thereby reducing overall system complexity and price while maintaining necessary adaptability.
Solution Approach 2:
The patent implements adjustable and configurable functional units that can be dynamically adapted to user needs. For example, the knee joint can be configured with different damping characteristics, and the foot unit can be adjusted for different activity levels. This dynamic configurability allows the same base product to serve multiple functions without requiring separate expensive specialized units.
2Adaptability or versatility
If multiple functions are installed in a prosthetic limb, then the quality of life of the user is improved, but it becomes difficult to evaluate the necessary functions objectively
Solution Approach 1:
The patent incorporates usage information recording functionality that tracks how each functional unit is actually used by the user. This usage data provides objective feedback on which functions are necessary and which are not, enabling precise evaluation of function necessity. The recorded information can be analyzed to determine the actual value provided by each function, replacing subjective evaluation with data-driven assessment.
3Measurement precision
If usage information is recorded for each function, then the necessity of functions can be evaluated objectively, but the system complexity increases
Solution Approach 1:
The patent implements a universal information recording mechanism that is integrated into the control system of the prosthetic limb. The same control unit that manages the multiple functional units also handles the recording and management of usage information for each function. This multi-functional approach allows usage tracking without adding separate dedicated hardware systems, thereby minimizing additional complexity while achieving precise evaluation capability.
