Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the temperature/moisture sensor is installed inside the surveillance camera device, then the device structure is simplified and manufacturing is easier, but the sensor is influenced by internal temperature/moisture causing measurement inaccuracy
Solution Approach 1:
The temperature/moisture sensor is extracted from the camera body and relocated to the cable module, which is positioned outside the camera housing. This separation allows the sensor to measure environmental conditions in the monitored space without being influenced by the internal temperature and moisture of the camera device, thereby improving measurement accuracy while the integrated cable module design keeps the overall structure compact.
2Measurement precision
If the temperature/moisture sensor is placed outside the camera in a cable module, then measurement accuracy is improved, but the device structure becomes more complex
Solution Approach 1:
The cable module integrates multiple functions including power supply connection, signal transmission, and temperature/moisture sensing into a single unified component. By combining these functions, the patent avoids the complexity of separate independent systems while achieving accurate environmental monitoring through the externally positioned sensor.
3Ease of operation
If a single cable is used for power and signal transmission, then cable management is simplified and ease of operation is improved, but the electrical connection requirements become more complex
Solution Approach 1:
The single cable connecting the camera to the external power source is designed to perform multiple functions simultaneously: it provides power supply transmission, carries signal transmission for camera operation, and transmits temperature/moisture sensor data. This multi-functional cable design simplifies installation and cable management while the internal circuitry handles the complexity of coordinating these multiple functions through a unified connection interface.
