Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vehicle lamp structures, particularly taillights, suffer from light leakage, inefficient light distribution due to vibration welding issues, and interference between light-emitting regions, leading to reduced light-emitting efficiency and product quality.
Innovation Solution
A vehicle lamp structure with a base, circuit board, light-emitting elements, ring block, optical elements, and optical cover, where the ring block surrounds the light-emitting elements, forming a closed space to enhance light efficiency and using a beveled optical element to reflect light rays for improved peripheral illumination, while preventing friction during assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a ring is used to contact the 3D round surface of the external lens, then the brake lamp structure is simplified, but light leakage occurs when the external lens is shifted
Solution Approach 1:
The patent divides the sealing structure into multiple segments: a sealing ring with first sealing surfaces and a lens mounting structure with corresponding second sealing surfaces. This segmentation allows independent optimization of each sealing interface and enables the lens to be securely mounted without relying on a single 3D round surface contact, thereby preventing light leakage while maintaining structural simplicity.
Solution Approach 2:
The patent introduces a sealing ring as an intermediary element between the lens and the housing. This sealing ring acts as a mediator that provides reliable light sealing through multiple sealing surfaces, decoupling the sealing function from the mounting function and allowing the lens to be securely positioned without direct reliance on the 3D round surface contact.
2Device complexity
If light-emitting elements are placed in open spaces, then the lamp structure is simpler, but light-emitting efficiency is reduced
Solution Approach 1:
The patent segments the lamp structure into distinct regions: a closed space for primary light-emitting elements and a non-closed space for secondary light-emitting elements. This segmentation allows each region to be optimized for its specific function while maintaining overall structural simplicity, with the closed space providing enhanced light efficiency for its elements.
Solution Approach 2:
The patent applies different spatial characteristics to different regions: the closed space provides a confined environment that enhances light efficiency for certain elements, while the non-closed space allows for simpler mounting of other elements. This local differentiation of spatial quality enables simultaneous optimization of both light efficiency and structural simplicity in different areas.
3Area of stationary object
If light-emitting elements are densely arranged, then the lamp size is reduced, but light ray interference increases
Solution Approach 1:
The patent divides the lamp into multiple light-emitting regions separated by the ring structure and optical elements. This segmentation spatially isolates different light-emitting elements, preventing light ray interference while maintaining a compact overall lamp size. Each region can be independently optimized without affecting adjacent regions.
Solution Approach 2:
The patent introduces optical elements and structural components as intermediaries between light-emitting elements. These intermediaries act as barriers or guides that prevent direct interference between light rays from different elements, allowing dense arrangement while maintaining optical quality.
4Productivity
If vibration welding is used for assembly, then manufacturing efficiency is improved, but fragment problems occur
Solution Approach 1:
The patent incorporates preliminary anti-friction design features into the structure before the vibration welding process. By pre-designing the geometry and material properties of the components, the patent prevents fragment generation during welding, allowing the use of efficient vibration welding without compromising product quality.

Implementation Method 1
The light rays emitted by the light-emitting elements located in the non-closed space will be reflected by the bevel of the optical element for solving the insufficient light on the periphery of the vehicle lamp
