Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle lamps struggle to effectively divide light into intended segment emission areas without using additional components like reflectors or resin lenses, leading to issues such as overlapping or improper light distribution.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If multiple reflectors are used to form multiple segment emission areas, then light can be divided into segment emission areas, but the relationship between reflectors and light-transmitting cover becomes unclear and adjacent segments may overlap
Solution Approach 1:
The patent removes the reflector component from the system entirely and replaces it with a light-shielding wall structure integrated into the housing. This extraction of the problematic reflector element eliminates the ambiguity in light-transmitting cover relationships while maintaining the light division function through the light-shielding walls and diffusing cover combination.
Solution Approach 2:
The patent combines the light-shielding function and structural support function into a single housing structure with integrated light-shielding walls. This merging eliminates the need for separate reflector components and simplifies the overall structure while achieving the same light division effect through the diffusing light-transmitting cover.
2Manufacturing precision
If additional components like reflectors or resin lenses are used to divide light, then segment emission areas can be formed, but the configuration becomes complex
Solution Approach 1:
The patent extracts and removes unnecessary components (reflectors, resin lenses) from the system, retaining only the essential elements: light-shielding walls integrated into the housing and a diffusing light-transmitting cover. This reduction achieves segment emission area formation with fewer components.
Solution Approach 2:
The light-transmitting cover serves multiple functions: it protects internal components, provides structural support, and diffuses light to form segment emission areas. The housing with light-shielding walls also serves both structural and light control functions, reducing the need for separate specialized components.
3Manufacturing precision
If light is not properly divided, then segment emission areas overlap, but using traditional methods requires complex additional components
Solution Approach 1:
The patent replaces the mechanical/optical system of reflectors and lenses with a simpler system based on light absorption (light-shielding walls) and light diffusion (diffusing cover). This substitution achieves accurate light division through material properties rather than complex geometric optical paths, simplifying manufacturing.
Solution Approach 2:
The patent changes the approach from geometric optical control (reflector shapes, lens curvatures) to material property control (light-shielding wall positioning, diffusing cover characteristics). By controlling parameters like wall height, spacing, and cover diffusion properties, accurate segment emission is achieved through simpler manufacturing parameters.

AI summary
A vehicle lamp includes: a light-transmitting cover; a semiconductor light-emitting element, wherein light emitted from the semiconductor light-emitting element passes through the light-transmitting cover; a pair of light-shielding walls disposed on both sides of the semiconductor light-emitting element and blocking a portion of the light emitted by the semiconductor light-emitting element; wherein a space is formed between the pair of light-shielding walls and the light-transmitting cover; the light-transmitting cover is subjected to processing for diffusing the light passing through the light-transmitting cover; and when a portion of the light emitted by the semiconductor light-emitting element is blocked by the pair of light-shielding walls and another portion of the light passes through the light-transmitting cover, a segment emission area including an outer shape defined by the pair of light-shielding walls is formed on the light-transmitting cover.
