Engineering Contradictions & Design Principles

VSEngineering 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

Engineering Contradiction:
ImprovefunctionalityVSAvoidalignment and guiding complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

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

Inventive Principle:
Principle #5Merging (Combining)

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

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Reliability

If dedicated support means are used for each component, then component stability is improved, but the number of parts and assembly complexity increases

Engineering Contradiction:
Improvecomponent stabilityVSAvoidnumber of parts
Core Design Contradiction:
ReliabilityVSDevice complexity

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

Inventive Principle:
Principle #5Merging (Combining)

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

Engineering Contradiction:
ImprovecompactnessVSAvoidcable management and component alignment
Core Design Contradiction:
Volume of moving objectVSEase of operation

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

Inventive Principle:
Principle #17Another dimension (Dimensionality change)
