Solution Overview
Problem
Existing automotive vehicle lighting systems face challenges in reducing size and cost due to the proliferation of separate lighting and signaling modules, which often utilize different technologies and power outputs, making integration difficult.
Innovation Solution
A motor vehicle lighting module that shares components between lighting and signaling functions, utilizing a common reflector and/or support to reduce the number of components and improve compactness, while maintaining luminous efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If separate signal units are used for different light signals, then signalling functionality is improved, but device complexity increases
Solution Approach 1:
The patent combines multiple light signals (brake light, indicator light, fog light) into a single light signal unit. Different signal types are generated by controlling different LED groups within the same unit, eliminating the need for separate signal units for each function and reducing overall device complexity while maintaining full signalling capability.
Solution Approach 2:
The light signal unit is designed to perform multiple functions simultaneously - it can display brake signals, indicator signals, and fog lights within a single unit. This multi-functionality is achieved through a control unit that selectively activates different LED groups based on the required signal type, allowing one unit to replace what would traditionally require multiple specialized units.
2Reliability
If a housing is provided for each light signal unit, then protection and structural integrity are improved, but device complexity increases
Solution Approach 1:
The patent employs a single housing structure that contains multiple light signal units rather than providing separate housings for each unit. This shared housing approach reduces the number of structural components and assembly steps while still providing adequate protection to all light signal units through the common housing structure.
3Measurement precision
If individual control units are used for each light signal, then control precision is improved, but device complexity increases
Solution Approach 1:
The control unit is designed as a multi-functional device that can precisely control different types of light signals (brake, indicator, fog light) within a single light signal unit. It selectively activates different LED groups based on the required signal type, achieving the control precision of multiple separate units while reducing device complexity through consolidation.
