Vehicle Indicator Light Assembly with Segmented Optical Channels
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing indicator light assemblies for vehicles lack the ability to independently illuminate multiple indicators, limiting their functionality and versatility.
Innovation Solution
The indicator light assembly features a housing with separate first and second light channels, each equipped with a dedicated light source to illuminate distinct indicators, such as 'on' and 'off' indicators for the airbag, ensuring independent illumination without light bleed-through.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If multiple indicators are illuminated using a single light source, then the device complexity is reduced, but light interference occurs between channels causing poor measurement precision
Solution Approach 1:
The patent divides the single light source into multiple separate light sources (first light source and second light source), with each light source dedicated to a specific indicator channel. This segmentation eliminates light interference between channels while maintaining clear indicator distinction, resolving the contradiction between device simplicity and illumination precision.
2Device complexity
If a single light channel is used for multiple indicators, then the device complexity is reduced, but light bleed-through occurs causing poor reliability
Solution Approach 1:
The patent creates separate light channels (first light channel and second light channel) for different indicators, preventing light bleed-through between channels. This structural segmentation ensures that each indicator receives light only from its designated source, improving reliability while maintaining clear functional distinction.
3Ease of manufacture
If indicators share a common housing without separation, then the ease of manufacture is improved, but light interference occurs reducing functionality
Solution Approach 1:
The patent incorporates internal partitions within the housing to create separate light channels while maintaining a unified external housing structure. This approach preserves manufacturing simplicity for the overall housing while enabling independent illumination control for each indicator, thus achieving both ease of manufacture and functional versatility.
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
Enables independent illumination of multiple indicators, enhancing the assembly's functionality and clarity by preventing light interference between channels, thus improving user comprehension of vehicle status.
Implementation Method 1
A first light source is disposed in the housing and configured to emit light through the first light channel to illuminate the first indicator
Implementation Method 2
A second light source is disposed in the housing and configured to emit light through the second light channel to illuminate the second indicator
