Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If wired transmission devices with cables and conductors are used to transmit status data, then data transmission between sensor device and control device can be achieved, but the system requires extensive installation space and generates electromagnetic interference
Solution Approach 1:
The patent replaces the mechanical wired transmission system (cables, conductors, plugs) with an optical transmission system using light signals. The sensor device and control device communicate through optical signals transmitted via the temperature control fluid line, eliminating the need for separate electrical cables and reducing electromagnetic interference while maintaining data transmission reliability
Solution Approach 2:
The temperature control fluid line serves dual functions: it continues to perform its original temperature control function while simultaneously serving as a transmission medium for optical signals. This multi-functionality eliminates the need for separate cabling for data transmission, reducing installation space and complexity
2Ease of operation
If multiple plugs or plug connections are used for wired data transmission, then connection between sensor device and control device can be established, but signal quality and transmission reliability deteriorate
Solution Approach 1:
The patent replaces mechanical plug connections with optical signal transmission through the temperature control fluid line. This eliminates contact resistance, oxidation, and connection errors associated with plugs, thereby improving signal quality and transmission reliability while maintaining ease of operation
3Loss of information
If wired transmission devices are used for status data transmission, then data can be transmitted between devices, but electromagnetic impurities are generated that affect battery system operation
Solution Approach 1:
The patent substitutes electrical signal transmission with optical signal transmission. By using light signals carried through the temperature control fluid line, the system eliminates electromagnetic field generation and susceptibility, preventing electromagnetic interference with battery system operation while maintaining effective data transmission
