Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If manual heating gear adjustment is used, then heating control flexibility is improved, but ease of operation deteriorates
Solution Approach 1:
The patent implements automatic heating control by detecting skin contact resistance through electrodes and using this feedback signal to automatically adjust heating intensity. The control unit receives the resistance change signal and autonomously regulates the heating element, eliminating the need for manual heating gear adjustment while maintaining adaptability to individual user needs.
Solution Approach 2:
The system performs self-adjustment of heating parameters based on detected physiological signals. When the user's skin contacts the electrodes, the system automatically measures the resistance and adjusts heating intensity without requiring user intervention or technical knowledge, making the device self-regulating and easy to operate.
2Ease of operation
If automatic temperature regulation based on bioelectric feedback is implemented, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The control unit serves multiple functions: it detects skin contact resistance changes, processes the feedback signal, and regulates heating intensity all through a single integrated component. This multi-functionality reduces the need for separate dedicated circuits for each function, thereby managing device complexity while achieving automatic temperature regulation.
Solution Approach 2:
The patent combines the heating control and temperature regulation functions into a unified automatic control system. The control unit integrates signal processing and heating regulation, merging multiple operational functions into one coordinated system that simplifies the overall device architecture despite the advanced control capabilities.
