Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If multiple optical elements are used to achieve desired light shape, then the light distribution performance is improved, but the structural complexity and mounting complexity increase
Solution Approach 1:
The patent merges the primary optical element and secondary optical element into a single integrated optical element with a unified light incident surface, light transmission portion, and light emitting surface. This integration eliminates the need for separate mounting brackets and reduces the number of parts while maintaining the optical functions of both elements, thereby reducing structural complexity while preserving optical system accuracy.
2Manufacturing precision
If multiple optical elements are arranged at an interval to form desired light shape, then the light distribution performance is improved, but the size of the lighting module increases
Solution Approach 1:
The patent combines multiple optical elements into a single integrated structure where the light transmission portion internally connects the light incident surface and light emitting surface. This eliminates the need for spatial separation and mounting brackets, significantly reducing the lighting module volume while maintaining precise optical pathways and relative position accuracy through internal geometric design.
3Ease of operation
If multiple optical elements are mounted separately with respective brackets, then the optical functions are achieved, but the mounting accuracy is affected by multiple mounting errors
Solution Approach 1:
The patent integrates multiple optical elements into a single piece with internal light transmission pathways, eliminating the need for separate mounting operations. This single-integration approach removes multiple mounting error accumulation points and simplifies the mounting process to a single operation, thereby improving both mounting ease and mounting accuracy simultaneously.
4Use of energy by moving object
If the primary optical element has longer length and secondary optical element has large size, then the light utilization rate is increased, but the overall module size increases
Solution Approach 1:
The patent designs the light transmission portion with an internal structure where the light transmission pathway is nested within the integrated optical element body. This nested design allows the optical element to maintain sufficient length for high light utilization while being compact in overall dimensions, effectively reducing the lighting module volume without sacrificing light utilization rate.

AI summary
Provided is an automotive lamp optical element and an automotive headlamp. The automotive lamp optical element includes a light-incident portion (11), a light-passing portion (12) and a light-emitting portion (13) sequentially connected and integrally formed. The light-incident portion (11) is configured to focus and emit light from a light source into the light-passing portion (12). The area of a longitudinal section of the light-passing portion (12) gradually increases in an optical axis direction. The light-emitting portion (13) protrudes in a direction facing away from the light-incident portion (11) and is configured to refract light emitted through the light-passing portion (12).
