Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a fixed CO detector is installed in a location, then CO detection coverage is improved, but installation flexibility and adaptability to various enclosed spaces deteriorates
Solution Approach 1:
The invention divides the CO detection function into portable segments that can be distributed across multiple locations. Instead of requiring one fixed detector per location, users can carry multiple phone devices with embedded CO sensors to different enclosed spaces, providing flexible coverage without permanent installation requirements.
Solution Approach 2:
The invention makes the phone case a multi-functional device by embedding CO detection capabilities directly into it. The phone case serves both its original protective function and the additional function of CO detection and warning, eliminating the need for separate fixed detectors in various enclosed spaces.
2Ease of operation
If a portable phone device is used in enclosed spaces, then mobility and convenience are improved, but CO detection capability deteriorates
Solution Approach 1:
The invention merges the CO detection function with the portable phone device by embedding a CO sensor and sensing circuit directly into the phone case. This combination allows the phone to maintain its portability while gaining CO detection capability, resolving the contradiction between mobility and detection reliability.
Solution Approach 2:
The invention introduces an intermediary sensing circuit embedded in the phone case that acts as a mediator between the CO environment and the phone's processing units. This intermediary component enables CO detection without requiring modifications to the phone itself, maintaining mobility while adding detection capability.
3Reliability
If a CO sensor is embedded in the phone case, then CO detection capability is improved, but device complexity increases
Solution Approach 1:
The invention extracts the CO sensing function from the main phone device and places it in a separate, dedicated sensing circuit embedded in the phone case. This extraction allows the phone case to have specialized detection hardware without adding complexity to the phone's main system, as the sensing circuit is a separate module.
Solution Approach 2:
The invention uses a disposable or replaceable CO sensor module embedded in the phone case, which can be easily replaced if needed. This approach reduces the overall complexity by using a simple, standalone sensing component rather than integrating a complex, permanent detection system into the phone's main structure.
