Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional power connectors are used to transmit power between devices, then power transmission is achieved, but surge occurs causing device malfunction or damage
Solution Approach 1:
A capacitance device is introduced as an intermediary component between the power source and the load. The capacitance device includes capacitors that are electrically connected in parallel with the power transmission path, serving as a mediator to absorb and filter surge while allowing normal power transmission to pass through.
Solution Approach 2:
The harmful surge energy is converted into a beneficial filtering action. The capacitors in the capacitance device absorb the surge energy during voltage spikes and release it during normal operation, effectively converting the harmful surge into a stabilizing effect that protects the connected devices.
2Reliability
If circuit protecting modules are added to prevent surge damage, then device protection is improved, but device complexity and cost increase
Solution Approach 1:
The surge protection function is merged with the power transmission path by integrating the capacitance device directly into the connector structure. The capacitors are electrically connected in parallel with the power transmission conductors, combining the power delivery path and the protection path into a unified structure that provides both functions simultaneously.
Solution Approach 2:
The capacitance device performs multiple functions: it filters surge during voltage spikes, stabilizes voltage during normal operation, and provides energy storage capability. This multi-functional component replaces the need for separate circuit protecting modules, simplifying the overall circuit structure while providing comprehensive protection.
