Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If temperature detection elements and transmission lines are used to implement over-temperature protection, then temperature monitoring capability is improved, but the number of components increases leading to more failure points and reduced reliability
Solution Approach 1:
The patent combines the temperature switch directly onto the connection circuit board, merging the temperature protection function with the existing circuit structure. This eliminates the need for separate temperature detection elements and transmission lines, reducing component count while maintaining monitoring capability through the integrated temperature switch that directly senses and responds to overheating conditions.
2Reliability
If multiple components are used for temperature detection and signal transmission, then temperature protection function is implemented, but device complexity increases
Solution Approach 1:
The temperature switch is integrated directly on the connection circuit board, merging multiple functions (temperature sensing, switching, and circuit connection) into a single integrated structure. This eliminates the need for separate temperature detection elements, transmission lines, and control circuits, significantly reducing device complexity while maintaining reliable over-temperature protection.
Solution Approach 2:
The connection circuit board serves multiple functions: it provides electrical connection between charging/discharging circuits and simultaneously hosts the temperature switch for over-temperature protection. This multi-functional design eliminates the need for dedicated temperature detection components, reducing overall device complexity while ensuring reliable protection functionality.
