Solution Overview
Problem
Conventional vehicle lamp modules have a complex structure with numerous components, leading to increased size, higher production costs, and reduced yield due to multiple parts and assembly errors.
Innovation Solution
A vehicle lamp optical element comprising one or more optical units with a light emitting surface and a light receiving structure that includes a light incident surface and a reflecting surface, configured to form an intermediate light image at a focal plane, and a light emitting surface to image this image forward, optionally with cutoff line structures to control light reflection and distribution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple components (lamp panel, driver, bracket, outer lens, light receiving structure, cutoff line baffle) are used to achieve lamp functionality, then the lamp can perform illumination and light control functions, but the overall size increases and structure becomes complex
Solution Approach 1:
The patent merges the lamp panel, driver, bracket, outer lens, light receiving structure, and cutoff line baffle into a single integrated optical element. The light receiving structure includes a light incident surface, reflecting surface, and cutoff line structure all in one component, eliminating the need for separate parts while maintaining illumination and light control functions.
Solution Approach 2:
The integrated optical element performs multiple functions simultaneously: light collection, light reflection, cutoff line formation, and illumination. The single component serves as both the light receiving structure and the optical lens, reducing the number of parts needed while achieving the same lamp functionality.
2Adaptability or versatility
If multiple components are used to achieve lamp functionality, then the lamp can perform illumination and light control functions, but manufacturing cost and assembly complexity increase
Solution Approach 1:
By combining multiple components into one integrated optical element, the patent reduces the number of parts that need to be manufactured and assembled. This single component approach eliminates multiple manufacturing processes and assembly steps, directly reducing production costs and simplifying manufacturing.
3Adaptability or versatility
If multiple components are used to achieve lamp functionality, then the lamp can perform illumination and light control functions, but assembly precision and yield decrease due to more tolerances
Solution Approach 1:
The patent integrates multiple functional components into a single optical element, eliminating the need for assembly between separate parts. This single component approach removes multiple assembly tolerances and alignment requirements, directly improving assembly precision and manufacturing yield.
4Adaptability or versatility
If more parts and assembly links are used, then the lamp can achieve complex light control functions, but production cost increases
Solution Approach 1:
The patent combines multiple light control functions (cutoff line formation, light reflection, light collection) into a single integrated optical element. This eliminates the need for multiple separate components and assembly steps, reducing production costs while maintaining complex light control capabilities.
