Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If resistance elements are added to provide adjustable resistance, then muscle strengthening capability is improved, but device complexity increases
Solution Approach 1:
The resistance elements are designed to be adjustable and removable, allowing the resistance level to be dynamically changed based on training needs. The resistance tubes can be easily attached and detached from the foot plate, enabling users to adjust resistance without complex mechanisms.
Solution Approach 2:
The resistance system is segmented into separate resistance tubes that can be independently adjusted. Multiple resistance elements can be used in parallel or individually, allowing for modular adjustment of resistance levels without requiring a completely different apparatus configuration.
2Measurement precision
If angle measurement indicators are added for precise measurement, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The plate angle indicator is designed to automatically display the rotation angle of the foot plate without requiring external measurement devices or complex calibration systems. The indicator is integrated into the base structure and provides self-service angle measurement functionality.
Solution Approach 2:
The angle measurement function is merged with the base structure of the apparatus. The plate angle indicator is integrated into the base, combining the measurement function with the supporting structure rather than being a separate added component.
3Reliability
If multiple resistance elements are secured to the base and bottom plate, then resistance reliability is improved, but manufacturing complexity increases
Solution Approach 1:
The base and bottom plate are designed with universal mounting features (threaded holes, brackets) that can accommodate multiple resistance elements in various configurations. The same structural components serve both as structural supports and as mounting points for resistance elements.
Solution Approach 2:
The resistance elements are designed for easy attachment and removal through threaded connections and hooks, allowing for dynamic configuration during assembly and disassembly without requiring complex manufacturing processes for each specific configuration.
