Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed elevation device is used, then the structure is simple, but the adaptability to different user needs is poor
Solution Approach 1:
The patent implements a dynamic adjustment mechanism that allows the leg elevation device to change its elevation angle and support position. The adjustable support structure enables the device to adapt to different user leg lengths, weights, and elevation requirements, transforming a static fixed device into a dynamic adaptable system that responds to varying user needs.
Solution Approach 2:
The device incorporates adjustable parameters including elevation angle, support position, and firmness level. These parameters can be modified to suit different users and therapeutic requirements, allowing the same device to provide customized leg elevation support without requiring multiple different devices.
2Ease of operation
If a basic elevation device is used, then the manufacturing cost is low, but the user comfort is insufficient
Solution Approach 1:
The leg elevation device is divided into multiple functional segments including the support structure, adjustment mechanism, cushioning elements, and control system. This segmentation allows each component to be optimized for its specific function while maintaining overall manufacturability, with standardized parts that can be produced efficiently.
Solution Approach 2:
The device integrates multiple functions into a single system: leg elevation, angle adjustment, position support, and comfort cushioning. This multi-functionality provides comprehensive user comfort without requiring multiple separate devices, balancing enhanced functionality with manufacturing efficiency.
3Measurement precision
If precise elevation control is implemented, then the therapeutic effectiveness is improved, but the device complexity increases
Solution Approach 1:
The pivoting mechanism with reverse gear enables dynamic and precise control of the elevation angle. The reverse gear mechanism allows for incremental adjustments and precise positioning at specific angles, providing therapeutic precision while using a mechanical system that remains relatively simple and maintainable.

AI summary
A leg elevation device includes a support structure to elevate a user's legs and an adjustment mechanism for dynamically adjusting the elevation to various desired heights. The adjustment mechanism allows the support structure to collapse to a planar configuration for storage and transport. The device is adaptable for use with different seating surfaces and includes angle straps for securing at variable angles. It features a pivoting mechanism with a reverse gear for incremental adjustments and a folding mechanism for easy transition between operational and collapsed states. The support structure can be made from materials like microfiber, synthetic leather, or nylon, and is designed to support up to 250 pounds. An elevation adjustment feature may be motorized, operating on a power source such as a 120-volt transformer system or a rechargeable battery.
