Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If LED lighting units are connected by connecting circuit boards with connectors, then electrical continuity is established, but the connection process becomes complex and insulation of terminal portions is required
Solution Approach 1:
The LED lighting unit is divided into multiple detachable LED sheet modules, each with integrated terminals. This segmentation allows independent handling and connection of modules without complex circuit board assembly, simplifying the overall connection process while maintaining electrical continuity.
Solution Approach 2:
The power receiving terminal and power feeding terminal are integrated directly onto the LED sheet substrate, merging the terminal functions with the lighting module itself. This eliminates the need for separate connector assemblies and circuit board connections, reducing structural complexity while enabling direct module-to-module connection.
2Adaptability or versatility
If rigid circuit boards are used for LED arrangement, then electrical connections are stable, but flexibility in installation and attachment to various surfaces is reduced
Solution Approach 1:
The circuit board is replaced with a flexible substrate that can bend and conform to various surface geometries. This flexible substrate maintains electrical connectivity through printed circuits or conductive traces, enabling stable electrical connections while providing the necessary flexibility for diverse installation scenarios such as curved surfaces or irregular geometries.
3Illumination intensity
If multiple LED chips are arranged on a large area substrate, then light distribution uniformity improves, but power consumption increases
Solution Approach 1:
Different regions of the LED sheet are equipped with LEDs of different colors or intensities tailored to specific functional requirements. This local differentiation allows optimized light distribution for algae culture requirements without uniformly increasing power consumption across the entire substrate, as each region provides only the necessary illumination characteristics.
