Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If high beam light sources are used to provide wide illumination range, then driver visibility is improved, but oncoming drivers are dazzled
Solution Approach 1:
The high beam light source is segmented into multiple LED light emitting units arranged in an array, with each unit corresponding to a light guiding member in the condenser. This segmentation allows selective activation of specific light emitting units to illuminate different road areas while avoiding illumination of oncoming drivers.
Solution Approach 2:
Different regions of the light emitting array are assigned different functions: edge light emitting units are configured to illuminate roadside areas, while central light emitting units illuminate the central road area. This local quality differentiation enables targeted illumination that avoids dazzling oncoming drivers while maintaining comprehensive road coverage.
2Area of stationary object
If multiple high beam light sources are activated to illuminate different road areas, then illumination coverage is improved, but control complexity increases
Solution Approach 1:
Multiple light emitting units and their corresponding light guiding members are merged into a single integrated condenser structure. This merging simplifies control by allowing the entire array to be controlled as one unit while maintaining the ability to selectively activate specific segments, thus expanding illumination coverage without proportionally increasing control complexity.
3Loss of energy
If light guiding members are arranged with acute angles to converge light, then light condensing efficiency is improved, but manufacturing precision requirements increase
Solution Approach 1:
The light guiding members are designed with curved or arc-shaped geometries rather than straight lines, allowing them to converge light effectively while accommodating manufacturing tolerances. The curved design naturally guides light from multiple LED units to a common focal region, reducing the stringency of alignment requirements compared to acute-angled straight configurations.
