Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle lighting systems require significant space for multiple light functions, leading to reduced room for each lighting system as more lights or longer lights are added, and there is a need for a system where multiple printed circuit boards can provide multiple lighting functions simultaneously, intermittently, or alternatively, while maintaining an extended length.
Innovation Solution
A light system comprising multiple printed circuit boards with sets of light sources that generate different colors or wavelengths of light, distributed through light bars with aligned light guides and blockers to prevent light interference, and controlled by controllers to manage the lighting effects.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple separate lighting systems are provided for different lighting functions, then each lighting function can be independently achieved, but the space required for each lighting system increases and reduces room for additional lights
Solution Approach 1:
Multiple lighting functions (headlights, fog lights, turn signals, running lights) are merged into a single integrated light system with multiple light bars arranged in parallel planes. This consolidation achieves various lighting functions simultaneously while reducing the overall space required compared to separate lighting systems.
Solution Approach 2:
The light system is designed as a universal multi-functional unit where a single system structure supports multiple lighting functions through different light bar configurations and control modes, allowing the same physical system to serve multiple purposes (illumination, signaling, warning) without requiring separate dedicated systems for each function.
2Adaptability or versatility
If longer lights or more lights are added to provide more lighting functions, then lighting coverage and functionality are improved, but the space required for the lighting system increases
Solution Approach 1:
The light bars are arranged in substantially parallel planes rather than extending linearly in a single direction. This three-dimensional spatial arrangement allows multiple lighting functions to be achieved within a more compact footprint, effectively utilizing vertical and depth dimensions to reduce the overall length and space requirements of the lighting system.
3Area of stationary object
If multiple light sources are provided in close proximity to achieve multiple functions, then space is saved, but light interference between different light sources may occur
Solution Approach 1:
Blockers are strategically positioned between adjacent light bars to extract or block light paths that would otherwise cause interference between neighboring light sources. This selective blocking prevents harmful light crossover while maintaining the compact multi-functional design, allowing each light bar to operate independently without interference from adjacent lights.
4Adaptability or versatility
If multiple printed circuit boards are used to provide multiple lighting functions, then lighting versatility is improved, but the device complexity increases
Solution Approach 1:
The lighting system is segmented into multiple independent printed circuit boards, each responsible for controlling specific light bars or lighting functions. This modular segmentation allows for easier manufacturing, testing, and maintenance while reducing the complexity of any single circuit board. Each PCB can be independently produced and replaced if needed, simplifying the overall system complexity despite having multiple boards.
