Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If LEDs are electrically assembled on a circuit board with spacing between them, then lighting performance is improved, but high-voltage static electricity accumulates during assembly causing LED damage
Solution Approach 1:
A conductive line is introduced as an intermediary component between the LEDs and the circuit board. This conductive line serves as a mediator that collects static electricity from the LEDs during assembly and transports it to a grounding point, preventing direct accumulation on the LEDs while maintaining the spaced arrangement needed for lighting performance
Solution Approach 2:
The conductive line enables the assembly process to be self-protecting by automatically collecting and discharging static electricity generated during assembly. The system serves itself by using the conductive line to neutralize harmful static charges without requiring external intervention or special handling procedures
2Reliability
If sharp portions are added to the circuit board to collect and discharge static electricity, then LED protection is improved, but device complexity increases
Solution Approach 1:
The conductive line is merged with the existing circuit board structure, integrating the static electricity collection and discharge function into the board's conventional design. The conductive line is positioned between adjacent LEDs and connected to existing conductive patterns, combining protection functionality with the existing structural framework rather than adding separate discrete components
Solution Approach 2:
The conductive line serves multiple functions: it provides electrical connection between LEDs, acts as a static electricity collection pathway, and functions as a discharge route to ground. This multi-functionality reduces the need for separate dedicated components, thereby limiting the increase in device complexity while achieving comprehensive LED protection
