Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a matrix assembly with multiple lighting elements is used to generate information light patterns, then the variability of light patterns is increased, but the device complexity increases
Solution Approach 1:
The patent combines a line assembly and a matrix assembly into a single illumination device, where the matrix assembly serves dual purposes: generating information light patterns and extending the line assembly to form a complete linear signal light function. This merging reduces overall device complexity while maintaining pattern variability.
Solution Approach 2:
The matrix assembly performs multiple functions: it generates information light patterns independently and simultaneously extends the line assembly to complete linear signal light functions. This multi-functionality increases adaptability without proportionally increasing device complexity.
2Adaptability or versatility
If separate line assembly and matrix assembly are used for signal light function and information light pattern, then functional versatility is improved, but the device complexity increases
Solution Approach 1:
The patent merges the line assembly and matrix assembly into an integrated illumination device where the matrix assembly forms a subarea of the line assembly. This spatial integration allows both signal light functions and information light patterns to be generated within a unified structure, improving functional versatility while controlling device complexity.
Solution Approach 2:
The illumination device is segmented into distinct functional areas: the line assembly for linear signal light functions and the matrix assembly for information light patterns, with the matrix forming a subarea of the line assembly. This segmentation allows independent control of each function while maintaining a compact integrated structure.
3Adaptability or versatility
If matrix assembly forms subarea of line assembly with direct spatial connection, then light pattern variability is increased, but manufacturing precision requirements increase
Solution Approach 1:
The matrix assembly is merged with the line assembly such that the matrix forms a subarea of the line assembly with direct spatial connection. This integration enables the matrix lighting elements to extend the linear light function while maintaining precise spatial alignment, achieving high light pattern variability with controlled manufacturing precision requirements.
