Vehicle Mirror Light Guide Plate Merging Multiple Sources
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Vehicle door mirror devices require separate light guide plates for multiple light sources, leading to increased space requirements for mounting, as existing systems cannot efficiently guide light from different sources to the outer side of the mirror housing without overlapping paths.
Innovation Solution
A mirror apparatus with a guide body that differentiates the light emission directions of multiple light sources using a differentiation portion, such as a redirection surface or dividing body, allowing the light from each source to be guided in distinct directions, thereby eliminating the need for separate guide members and reducing space requirements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate light guide plates are provided for each light source and window portion, then each light source can be guided independently, but the space required for mounting the light guide plates becomes larger
Solution Approach 1:
The patent combines multiple light guide plates into a single integrated light guide plate that serves multiple light sources and window portions. This single light guide plate includes multiple light guide portions that can be arranged in a matrix pattern, allowing independent light guidance for each light source while occupying less mounting space than separate plates would require.
Solution Approach 2:
The single light guide plate performs multiple functions by guiding light from multiple different light sources to multiple different window portions simultaneously. Each region of the light guide plate can be configured to direct light from specific light sources to specific window portions, enabling one component to replace what would traditionally require multiple separate components.
2Adaptability or versatility
If multiple separate guide members are provided for multiple light sources, then each light path can be controlled independently, but the device complexity increases
Solution Approach 1:
The single light guide plate is segmented into multiple functional light guide portions, each capable of independently guiding light from specific light sources to specific window portions. These segments can be arranged in a matrix pattern where each segment corresponds to a particular light source-window portion pair, maintaining independent control flexibility while using a unified structure.
Solution Approach 2:
Multiple separate guide members are merged into a single integrated light guide plate that maintains the functional independence of each light path. The plate includes multiple light guide portions with different optical characteristics or orientations, allowing each portion to control its specific light path while being part of a single component rather than requiring multiple separate pieces.

Function Achieved in This Case
This solution enables the use of a single guide body for multiple light sources, reducing the space needed for mounting and enhancing the efficiency of light guidance, while maintaining effective illumination and warning displays for occupants.
Implementation Method 1
a guide body that guides light emitted by the first emission member and light emitted by the second emission member to an outer side of the design body
Implementation Method 2
the differentiation portion reflects the light emitted by one of the first emission member or the second emission member

AI summary
A mirror apparatus for a vehicle includes a design body, a first emission member, a second emission member, a guide body and a differentiation portion. The design body includes a mirror provided at a vehicle, and the design body structures a design surface. The first emission member emits light and the second emission member emits light. The guide body guides the light emitted by the first emission member and the light emitted by the second emission member to an outer side of the design body. The differentiation portion makes directions in which the light emitted by the first emission member and the light emitted by the second emission member are guided by the guide body different.
