Vehicle Lighting Frame Segmentation for Illumination Area
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vehicle interior lighting devices with light emitting diodes face challenges in maximizing illumination area due to the design constraints of their housing and frame, which limits their integration with vehicle interior materials and can result in reduced light emission and increased glare.
Innovation Solution
The lighting device incorporates a housing with an inclined side surface for improved light emission, a frame with a holding section exposed from the cover to enhance illumination area, and a cover with a light guide section to minimize light blocking, allowing for a larger irradiation area while matching the vehicle's design aesthetics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the edge section of the frame is made larger to provide structural support, then the structural strength is improved, but the illumination area of the outer lens becomes smaller
Solution Approach 1:
The frame is divided into an edge section and a holding section. The edge section provides structural support while the holding section is designed to minimize light blocking. This segmentation allows each part to optimize its function without compromising the other.
Solution Approach 2:
Different sections of the frame have different design priorities. The edge section is designed for structural strength with appropriate thickness, while the holding section is designed with minimal interference to maximize light transmission. This local optimization resolves the contradiction between structural requirements and illumination requirements.
2Stability of the object's composition
If the width dimension of the edge of the edge section is increased to enhance structural stability, then the stability is improved, but it becomes difficult to merge into the design of the interior material of the vehicle
Solution Approach 1:
The holding section is extracted as a separate functional element from the edge section. This allows the edge section to maintain its structural width for stability, while the holding section can be independently designed to match vehicle interior aesthetics and be easily integrated into different design schemes.
Solution Approach 2:
The holding section serves multiple functions: it provides structural support, minimizes light blocking, and acts as a design element that can be adapted to match various vehicle interior materials. This multi-functionality allows the frame to maintain stability while being versatile in design integration.
3Object-affected harmful factors
If the cover is made more opaque to reduce glare, then the glare reduction is improved, but the illumination area and light distribution are reduced
Solution Approach 1:
The cover's optical properties are optimized by adjusting its translucency parameter. Instead of making it completely opaque or completely transparent, the cover uses a specific translucency level that balances glare reduction with light transmission, allowing beneficial light distribution while minimizing harmful glare effects.

Function Achieved in This Case
This configuration increases the illumination area, reduces glare, and allows for better integration with vehicle interior designs by using materials with high reflectivity and thermal conductivity, ensuring effective light distribution and aesthetic compatibility.
Implementation Method 1
a cover (6) that covers the opening of the frame (4) and has translucency; and a light guide section extending toward the light emitting section
Implementation Method 2
a housing (2) that stores the light emitting section (3); and a side surface (2d) of an inside of the housing (2) that is inclined in a direction in which a side of a bottom surface (2c) is close to a center of the housing (2)
