Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If ordinary dry cells are used to power the heating element, then the device structure is simple, but the temperature of the heating element becomes non-uniform and unstable
Solution Approach 1:
The patent implements a feedback control system using a temperature sensor to detect the heating element's temperature and feed it back to the control unit. The control unit adjusts the power delivery based on this feedback, maintaining stable and uniform temperature despite using simple power sources like dry cells.
Solution Approach 2:
The patent employs dynamic power adjustment where the control unit continuously modifies the power delivered to the heating element based on real-time temperature conditions. This dynamic control compensates for the limitations of ordinary dry cells, ensuring temperature stability without requiring high-capacity batteries.
2Device complexity
If a heating element with single heating function is used, then the device is simple, but the itching relieving effect is poor
Solution Approach 1:
The patent combines multiple therapeutic functions into one device: heating therapy through the heating element and blue light therapy through the LED unit. This multi-functional approach enhances the itching relieving effect while maintaining relatively simple device structure, addressing both thermal and optical therapeutic needs.
Solution Approach 2:
The patent merges heating therapy and blue light therapy into a single integrated apparatus. The control unit coordinates both the heating element and LED unit to work together, providing combined therapeutic effects that are more effective than either modality alone, while avoiding the complexity of separate devices.
3Ease of operation
If the heating element temperature is not stable, then the device operation is simple, but the therapeutic effect on patients is poor
Solution Approach 1:
The patent uses a temperature sensor to continuously monitor the heating element's temperature and provides feedback to the control unit. This feedback mechanism automatically maintains stable temperature without requiring complex user intervention, preserving ease of operation while ensuring reliable therapeutic effect.
Solution Approach 2:
The patent implements self-regulating temperature control where the system automatically adjusts its own operation based on temperature feedback. The control unit monitors and regulates the heating element without user intervention, maintaining stable temperature and therapeutic effectiveness while keeping the device simple to operate.
