Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple electronic and optical components are interconnected with varying geometries in limited space, then the functionality of the light device is improved, but the alignment and guiding complexity increases
Solution Approach 1:
The patent combines cable guiding means and component receiving means into a single integrated rigid structure. The guiding device houses both the cable routing pathways and the mounting positions for printed circuit boards and optical components within one unified structure, eliminating the need for separate support elements and reducing overall assembly complexity
Solution Approach 2:
The rigid structure serves multiple functions simultaneously: it guides cables through defined pathways, provides receiving means for mounting printed circuit boards, supports optical components like light guides, and maintains precise spatial relationships between all components. This multi-functional design reduces the number of separate parts needed in the limited space
2Reliability
If dedicated support means are used for each component, then component stability is improved, but the number of parts and assembly complexity increases
Solution Approach 1:
The patent merges multiple support functions into a single rigid structure that provides both cable guidance and component mounting capabilities. Instead of using separate support elements for each component, the integrated structure provides all necessary support, fixing, and alignment functions in one piece, thereby reducing the total number of parts while maintaining component stability
3Volume of moving object
If space is reduced to meet vehicle design constraints, then the compactness of the light device is improved, but the available space for cable management and component alignment decreases
Solution Approach 1:
The rigid structure utilizes three-dimensional space efficiently by creating vertical and horizontal pathways within the compact volume. The guiding structure extends in multiple directions (along axes) to provide adequate cable routing space and component mounting areas without increasing the overall external dimensions of the light device, thus maintaining compactness while enabling proper cable management and alignment
