Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a lens is provided on the light-emitting surface to control luminous intensity distribution, then the luminous intensity distribution can be controlled, but the manufacturing cost increases significantly
Solution Approach 1:
The patent changes the physical parameter of the light-emitting element's position (distance from substrate) to control luminous intensity distribution. By adjusting the mounting distance of different light-emitting elements, the patent achieves different light distribution patterns without requiring additional optical components, thereby resolving the contradiction between illumination control and manufacturing cost.
2Illumination intensity
If a lens is provided on the light-emitting surface to control luminous intensity distribution, then the luminous intensity distribution can be controlled, but the device complexity increases
Solution Approach 1:
The patent uses parameter change (position adjustment) instead of adding complex optical elements. By varying the distance between light-emitting elements and the substrate, the patent achieves different luminous intensity distributions without requiring lens design, thus reducing device complexity while maintaining illumination control capability.
3Adaptability or versatility
If lenses are changed according to different luminous intensity distribution requirements, then different applications can be satisfied, but the manufacturing cost increases significantly
Solution Approach 1:
The patent creates a dynamic configuration where light-emitting elements can be positioned at different distances from the substrate to achieve different luminous intensity distributions for various applications. This dynamic positioning approach eliminates the need for multiple lens types, allowing the same light-emitting elements to serve multiple applications and significantly reducing manufacturing costs.
4Adaptability or versatility
If multiple types of light-emitting elements are used to achieve different luminous intensity distributions, then different applications can be satisfied, but the device complexity increases
Solution Approach 1:
The patent uses dynamic positioning of identical light-emitting elements at different distances from the substrate to achieve different luminous intensity distributions. This approach maintains configuration simplicity by using the same element types while varying their positions, thereby achieving application adaptability without increasing device complexity.
