Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If conventional headlight lens designs are used, then manufacturing costs are high, but manufacturing simplicity is reduced
Solution Approach 1:
The patent combines multiple lens functions (light guidance, reflection, refraction, and pattern formation) into a single monolithic lens body. The light tunnel, passage section, and bend features are integrated as one piece, eliminating the need for multiple separate components and reducing assembly complexity while maintaining optical performance.
Solution Approach 2:
The lens is segmented into distinct functional zones (light tunnel section, passage section, bend section) with specific geometric features. This segmentation allows each zone to perform its optical function independently while being manufactured as a unified structure through injection molding, simplifying the overall manufacturing process.
2Productivity
If conventional headlight designs are used, then lighting distribution efficiency is insufficient, but compactness and dimming capability are reduced
Solution Approach 1:
The patent introduces a bent light tunnel that changes the optical path in three-dimensional space. The bend section redirects light at specific angles to achieve precise lighting distribution patterns while maintaining a compact overall headlight structure, effectively utilizing spatial dimensions to optimize light delivery.
Solution Approach 2:
Different sections of the lens have specialized geometric features optimized for their specific optical functions. The light tunnel has specific curvature radii, the passage section has defined exit face angles, and the bend section has precise angular geometry. This local optimization of geometric properties enhances lighting distribution efficiency while keeping the overall design compact.
