Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If multiple light sources are applied to achieve sequential lighting mode, then aesthetic appearance is improved, but the number of parts is increased and system complexity is increased
Solution Approach 1:
The lighting unit is segmented into multiple light-emitting regions along a light guide, with first and second light sources positioned at opposite ends. Each light source independently illuminates its end of the light guide, creating sequential lighting effects without requiring multiple light sources at each position. This segmentation approach achieves aesthetic diversity while reducing overall system complexity.
Solution Approach 2:
The light guide serves multiple functions: it transmits light from both ends, creates sequential lighting patterns, and provides structural support for the lighting unit. By making the light guide multi-functional, the system reduces the need for additional components while achieving complex lighting effects.
2Shape
If multiple light sources are applied to achieve sequential lighting mode, then aesthetic appearance is improved, but costs are increased
Solution Approach 1:
Multiple light-emitting functions are merged into a single light guide structure illuminated by only two light sources. The light guide integrates light transmission, sequential pattern creation, and structural support functions, reducing the total number of components and associated costs while maintaining aesthetic appeal.
3Shape
If lighting time of each light source is controlled to achieve sequential lighting mode, then aesthetic appearance is improved, but control complexity is increased
Solution Approach 1:
The controller implements periodic lighting cycles where the first light source and second light source are activated in sequence with controlled timing. By using simple periodic on/off patterns with adjustable durations, the system achieves diverse sequential lighting effects without requiring complex control algorithms or additional hardware.
