Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle lighting devices face challenges in achieving homogeneous light distribution, reducing glare, and minimizing installation complexity, while also being energy-efficient and cost-effective, particularly in the context of electromobility.
Innovation Solution
A lighting device with a two-part housing featuring a light channel and a light guide that can be constructed with diffuse or directed properties, using reflective materials and coatings to influence light emission and distribution, and incorporating an intermediate wall to reduce light mixing, with the light guide being either a single or multi-component element and potentially injection-molded onto the housing parts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a light guide element is used to distribute light, then homogeneous illumination is achieved, but light mixing and unwanted light pollution occur
Solution Approach 1:
The housing is divided into multiple segments (first housing part, second housing part, intermediate wall) that compartmentalize the light paths. The intermediate wall acts as a separator between different light guides, preventing light mixing while maintaining homogeneous illumination through each individual light guide element.
Solution Approach 2:
Different regions of the housing are assigned different functions: the first housing part contains the first light guide for one lighting function, the second housing part contains the second light guide for another lighting function, and the intermediate wall provides light-tight separation. This local differentiation prevents unwanted light pollution while maintaining homogeneous illumination in each zone.
2Adaptability or versatility
If multiple lighting functions are integrated into one device, then device versatility is improved, but device complexity increases
Solution Approach 1:
The housing is segmented into distinct parts (first housing part, second housing part) with an intermediate wall, allowing each segment to house independent light guides for different lighting functions. This modular segmentation enables multiple lighting functions while keeping each functional unit relatively simple and manageable.
Solution Approach 2:
The housing structure is designed as a universal container that can accommodate multiple different light guides with different functions. The standardized housing design with segmented compartments allows various lighting functions to be integrated without requiring completely different structural solutions for each function.
3Ease of operation
If light channels are used to direct light, then light distribution control is improved, but installation complexity increases
Solution Approach 1:
The light channels are integrated directly into the housing structure itself rather than being separate components. The first housing part and second housing part form the light channels as part of their structural design, eliminating the need for separate channel installations and simplifying the overall installation process while maintaining precise light distribution control.
