Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Vehicle tail light systems experience downtime due to faulty lights, and providing redundant lights increases costs and complexity, necessitating a solution that allows continuous operation without additional downtime or redundant lights.
Innovation Solution
A tail light unit utilizing RGB LED light sources with adjustable color and intensity, capable of substituting multiple lighting functions, including brake, turn indicator, fog, and reverse lights, using independent power supplies and trigger signals to ensure continuous operation even if one light source fails.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If redundant lights are provided to substitute faulty lights, then vehicle operation continuity is improved, but costs and device complexity increase due to additional lamps
Solution Approach 1:
The patent applies multi-functionality by enabling each tail light unit to perform multiple lighting functions (brake light, taillight, turn indicator) through software-controlled RGB LED color changes. A single tail light unit can substitute for multiple different light functions by changing its emitted color, eliminating the need for separate redundant lamps for each function type.
Solution Approach 2:
The patent combines multiple separate lighting functions into a single integrated tail light unit that can emit different colors. By merging brake light, taillight, and turn indicator functions into one multi-functional unit, the system reduces the total number of lamps while maintaining operational continuity capability.
2Reliability
If traditional separate lights are used for different functions, then lighting function reliability is maintained, but adaptability and substitution capability are reduced
Solution Approach 1:
The tail light unit is designed with universal functionality to perform multiple lighting roles. Through the control unit receiving different trigger signals, a single tail light unit can emit red light for brake/taillight functions or amber light for turn indicator functions, providing both reliability and high adaptability for substitution.
Solution Approach 2:
The patent introduces dynamic adaptability by enabling the tail light unit to change its function in real-time based on trigger signals. The lighting function is not fixed but dynamically adjustable through color control, allowing the system to adapt to different operational requirements and substitute for various light functions as needed.
