Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the entire space of the LED circuit board is fully occupied by electronic elements and circuits, then the lighting function is fully implemented, but no additional functions such as radio frequency signal reception and transmission can be integrated
Solution Approach 1:
The patent utilizes the third dimension (vertical layering) by implementing the antenna unit on the first circuit layer while positioning conductive traces on the second circuit layer. This multi-layer spatial arrangement allows the antenna functionality to be integrated without occupying additional planar space on the circuit board, effectively resolving the space constraint while enhancing adaptability.
Solution Approach 2:
The circuit board is designed to perform multiple functions simultaneously: lighting through LED units on the first circuit layer and radio frequency signal reception/transmission through the antenna unit on the same layer. The conductive traces on the second circuit layer provide grounding functionality while clearing space above for antenna operation, enabling the single circuit board to serve both lighting and communication purposes.
2Reliability
If conductive traces are densely arranged on the second circuit layer, then grounding circuit functionality is optimized, but space for antenna unit integration is reduced
Solution Approach 1:
The grounding circuit is segmented into multiple conductive traces arranged in a specific pattern on the second circuit layer. These traces are positioned to provide effective grounding functionality while creating a clearance area in the central region. This segmentation allows the grounding circuit to maintain its reliability while freeing up space for the antenna unit to be integrated on the first circuit layer.
Solution Approach 2:
The conductive traces are strategically positioned toward one side of the second circuit layer, creating a non-uniform distribution pattern. This local arrangement optimizes grounding performance in specific areas while deliberately leaving a clearance area in the central region, enabling the antenna unit to be integrated on the first circuit layer without compromising grounding circuit reliability.
