Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If printed circuit boards are designed specifically for each lighting module application, then the lighting module can be optimized for its specific requirements, but the manufacturing and storage costs increase due to inability to reuse boards
Solution Approach 1:
The printed circuit board is designed with universal terminals and selection means that enable it to function across multiple lighting module applications. The board includes first and second positive terminals, first and second negative terminals, and selection means with multiple configurations, allowing a single board design to serve various voltage and current supply requirements without needing application-specific variants.
Solution Approach 2:
The printed circuit board incorporates selection means that can be configured in different states to adapt the board's functionality. By changing the configuration of the selection means (which may include jumpers, switches, or reconfigurable connections), the same physical board can be dynamically adapted to different electrical configurations, enabling reuse across applications without manufacturing new boards.
2Ease of manufacture
If printed circuit boards are designed with fixed LED configurations, then manufacturing is simplified, but the boards cannot be reused for applications with different LED pitch or configurations
Solution Approach 1:
The printed circuit board divides the LED connection path into segments with selection means positioned between them. This segmentation allows independent configuration of different LED string connections by changing the state of the selection means, while the physical board structure remains fixed and manufacturable using standard processes.
3Device complexity
If lighting modules use fixed voltage or current supply configurations, then the design is simpler, but the modules cannot adapt to different electronic converters
Solution Approach 1:
The printed circuit board incorporates universal terminals and selection means that enable it to function across multiple lighting module applications. The board includes first and second positive terminals, first and second negative terminals, and selection means with multiple configurations, allowing a single board design to serve various voltage and current supply requirements without needing application-specific variants.
