Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed configuration of light sources is used in vehicle lamps, then the structural stability is maintained, but the design freedom and light distribution efficiency are limited
Solution Approach 1:
The patent applies the dynamics principle by transitioning from fixed light source configurations to flexible arrays that can be bent and shaped according to design requirements. The flexible array allows the light source configuration to adapt dynamically to different lamp designs while maintaining structural integrity through proper mounting structures.
Solution Approach 2:
The patent implements this principle by using flexible arrays as the light source substrate, which can be bent and conform to various shapes. This flexible array replaces traditional rigid light source configurations, enabling enhanced design freedom while maintaining ease of manufacture through flexible mounting structures.
2Illumination intensity
If uniform light sources are used across the lamp, then the manufacturing simplicity is maintained, but light intensity uniformity and color consistency deteriorate
Solution Approach 1:
The patent applies local quality by dividing the flexible array into different regions with different curvatures, where each region contains light sources with specific shapes and orientations tailored to that region's requirements. This ensures uniform light intensity and color consistency across the entire lamp while maintaining manufacturing simplicity through modular regional design.
Solution Approach 2:
The patent segments the flexible array into multiple regions based on curvature characteristics, with each region containing appropriately configured light sources. This segmentation allows for optimized light distribution in each region while simplifying the manufacturing process by treating each region as a manageable module.
3Productivity
If micro LED chips with different shapes are disposed in different regions, then light distribution efficiency is improved, but device complexity increases
Solution Approach 1:
The patent implements local quality by configuring micro LED chips with different shapes in different regions of the flexible array according to the specific curvature and light distribution requirements of each region. This optimizes light distribution efficiency while managing complexity through region-specific design rules.
Solution Approach 2:
The patent applies parameter changes by varying the shape and orientation parameters of micro LED chips based on the curvature and position within the flexible array. This allows optimization of light distribution efficiency across different regions while maintaining a systematic approach to managing configuration complexity.
