Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If conventional LED lighting devices use color filters or filter holes to express desired shapes and colors, then the atmospheric effect can be achieved, but the device configuration becomes mechanically complicated
Solution Approach 1:
The patent replaces mechanical filter systems with optical patterns that directly shape light. The patterns are formed on the light-emitting surface of the LED package, eliminating the need for separate color filters and filter hole structures. This substitution of mechanical filtering components with integrated optical patterns reduces device complexity while maintaining the ability to express desired shapes and colors.
Solution Approach 2:
The patent merges the light-emitting function and the light-shaping function into a single integrated structure. The patterns are formed directly on the light-emitting surface of the LED package, combining what were previously separate components (LED light source and color filters) into one unified element. This integration simplifies the overall device configuration and improves ease of installation and maintenance.
2Adaptability or versatility
If conventional LED lighting devices use multiple components to control light shape and color, then the desired optical image can be expressed, but the degree of freedom in design is limited
Solution Approach 1:
The patent applies local quality by varying the patterns at different locations on the light-emitting surface. Each region can have different pattern characteristics (such as different colors, shapes, or light transmission properties) to achieve diverse optical images. This local differentiation provides high design freedom without requiring multiple separate components, as each location can be independently optimized for its specific function.
Solution Approach 2:
The patent utilizes the two-dimensional light-emitting surface of the LED package to create complex three-dimensional optical images. By patterning the light-emitting surface in specific two-dimensional arrangements, the system can generate three-dimensional visual effects and atmospheric lighting. This dimensional transformation provides extensive design freedom without increasing mechanical complexity.
3Illumination intensity
If conventional LED lighting devices use intricate configurations to express atmospheric effects, then the desired optical image can be achieved, but the device becomes difficult to install and maintain
Solution Approach 1:
The patent makes the LED package self-sufficient by integrating the light-shaping patterns directly onto its light-emitting surface. The patterns are formed as part of the LED package structure itself, eliminating the need for separate external filters or optical components that would require additional installation steps. This self-integrated design maintains high optical image quality while significantly improving ease of installation and maintenance.
