Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If traditional bright light sources are used for illuminating vehicle surfaces to identify deformities, then illumination intensity is improved, but eye strain increases and measurement precision deteriorates
Solution Approach 1:
The light guide panel creates non-uniform illumination with alternating bright and dark stripes across the vehicle surface. This localized variation in light intensity allows different regions to highlight different aspects of surface deformities, improving identification accuracy without requiring uniformly high intensity that causes eye strain
Solution Approach 2:
The patent changes the illumination parameter from uniform high intensity to non-uniform alternating intensity patterns. By transforming the light distribution pattern through refraction elements, the system achieves effective deformity detection with lower overall intensity, reducing eye strain while maintaining measurement precision
2Illumination intensity
If traditional high power light sources are used, then illumination effectiveness is improved, but power consumption increases and device complexity increases
Solution Approach 1:
The light guide panel acts as an intermediary between the light source and the vehicle surface. It transforms the light from a standard LED strip into alternating bright and dark stripes through refraction elements, achieving effective illumination with lower power consumption by optimizing light distribution rather than relying on high power
Solution Approach 2:
The system changes the light distribution parameter from uniform to non-uniform alternating patterns, which improves illumination effectiveness for deformity detection while reducing the total power required. The refraction elements modify light parameters to create effective contrast patterns without increasing power consumption
3Device complexity
If uniform light distribution is used, then simplicity is maintained, but deformity identification precision deteriorates
Solution Approach 1:
Instead of uniform light distribution, the patent implements local quality variation with alternating bright and dark stripes. This non-uniform pattern enhances the visibility of surface deformities by creating contrast variations that highlight irregularities, improving detection precision while adding only moderate complexity through the light guide panel and refraction elements
