Vehicle Door Mirror Light Integration via Merged Cover
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vehicle door mirrors with light-emitting functions require complex structures due to separate light-emitting blocks, compromising design and aesthetics.
Innovation Solution
A vehicle functional component with a molded cover made of translucent resin and a surface-emitting device, where light from the device is transmitted through a light transmissive film to create a diffused light-emitting area, eliminating the need for a separate light-emitting block and simplifying the structure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a separate light-emitting block is combined with the door mirror to obtain light-emitting function, then the light-emitting function is achieved, but the structure becomes complicated and design is impaired
Solution Approach 1:
The patent merges the light-emitting function directly into the door mirror assembly by integrating the light source, light guide, and diffusing layer within the mirror housing structure. This eliminates the need for separate light-emitting blocks while achieving the desired illumination effect, thereby simplifying the overall structure and improving design integration.
2Ease of manufacture
If a separate light-emitting block is combined with the door mirror to obtain light-emitting function, then the light-emitting function is achieved, but the appearance and beauty are compromised
Solution Approach 1:
The light-emitting components are merged into the door mirror housing in a way that maintains aesthetic appearance. The light guide and diffusing layer are integrated within the existing mirror structure, allowing the light to emit uniformly without disrupting the external design lines or visual appeal of the door mirror.
3Ease of manufacture
If members are formed separately to obtain light-emitting function, then the light-emitting function is achieved, but space for housing the light-emitting block is required
Solution Approach 1:
The light guide and diffusing layer are nested within the existing door mirror housing structure. The light guide is positioned behind the diffusing layer, and both are integrated into the available space within the mirror assembly, eliminating the need for additional external housing space while maintaining functional effectiveness.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This approach allows for a compact, aesthetically pleasing light-emitting function without the complexity of separate light-emitting blocks, enhancing the appearance and design of vehicle components.
Implementation Method 1
a light transmissive film having a light diffusion effect is disposed between a back face side of the molded cover (1) and a surface side of the surface-emitting device (2) and the light from the surface-emitting device (2) passes through the light transmissive film (4) and shines on a surface side of the molded cover (1) in a diffused state

AI summary
The invention obtains a light-emitting function of a vehicle functional component with a relatively simple structure and in a relatively compact form. Moreover, the invention provides a vehicle functional component design of which is not impaired and which is excellent in beauty and appearance. A vehicle component includes a molded cover (1) molded into a shape of a surface of a part attached to a vehicle and a surface-emitting device (2) bonded or fitted and fixed along a back face of the molded cover (1). The molded cover (1) is vacuum formed by solid decorative molding of a translucent resin molded member with a translucent film, and light from the surface-emitting device (2) is transmitted through the molded cover (1) and emerges in a predetermined light-emitting area which is a part of a surface of the vehicle component.
