Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If different flexible printed circuit boards are used for different dimensions of liquid crystal panels, then the light module can adapt to various panel sizes, but the production process becomes complex and materials are wasted
Solution Approach 1:
The light module is divided into multiple independent LED package units that can be separately arranged and connected. Each unit contains its own LED array and connecting structure, allowing them to be configured in different patterns (linear, L-shaped, U-shaped, etc.) to match various panel dimensions without requiring different circuit board designs
Solution Approach 2:
A universal connecting unit structure is designed with standardized connection interfaces that can accommodate multiple arrangement configurations. The same basic unit can serve different functions by changing its position and orientation, eliminating the need for multiple specialized circuit board designs
2Illumination intensity
If different flexible printed circuit boards are used for different luminosities, then the light module can meet various illumination requirements, but production time and material costs increase
Solution Approach 1:
The light module is segmented into multiple LED package units with adjustable quantities. By increasing or decreasing the number of units and their arrangement density, the overall luminosity can be customized for different applications without requiring different circuit board specifications
Solution Approach 2:
The module allows dynamic configuration of LED unit arrangements during assembly. The connecting units can be positioned at different intervals and orientations to create variable light output patterns, enabling a single module design to adapt to different luminosity requirements
