Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a device uses complex fastening mechanisms to secure the lower legs during exercise, then the reliability of leg support is improved, but the device complexity increases and ease of operation deteriorates
Solution Approach 1:
The patent extracts the fastening function from a complex mechanism and implements it through simple elastic bands that extend around the ankles. This allows the device to secure the lower legs reliably without requiring complex fastening systems, thereby maintaining reliability while reducing device complexity and improving ease of operation.
Solution Approach 2:
The patent employs simple, inexpensive elastic bands instead of complex, expensive fastening mechanisms. These bands are easily replaceable and sufficient for the intended use, achieving reliable leg support through a simple, cost-effective solution that reduces overall device complexity.
2Adaptability or versatility
If a device is designed to be adjustable to various user anatomies, then the adaptability is improved, but the device complexity increases
Solution Approach 1:
The patent achieves adaptability to various user anatomies by making the angle between the supporting surfaces adjustable. The base body can be configured at different angles to accommodate different knee fold angles and user anatomies, providing versatility without requiring complex adjustment mechanisms, thus improving adaptability while keeping device complexity low.
Solution Approach 2:
The patent incorporates movable elements that allow the base body angle to be adjusted and locked at different positions. This dynamic capability enables the device to adapt to various user anatomies and exercise requirements while maintaining a relatively simple overall structure through straightforward adjustment and locking mechanisms.
3Stability of the object's composition
If a device uses multiple parts and complex structures to provide stable support, then the stability is improved, but the ease of manufacture deteriorates
Solution Approach 1:
The patent merges multiple functions into a single integrated base body structure that provides stable support for the lower legs. The base body itself is designed with geometric features and angle adjustments that provide stability without requiring additional complex components, thereby improving stability while maintaining ease of manufacture through reduced part count and simplified assembly.
