Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle light assemblies lack a comprehensive solution for effectively illuminating the exterior area beneath a vehicle's underbody and projecting images in a coordinated manner, especially when the vehicle transitions from a locked to an unlocked state.
Innovation Solution
A vehicle light assembly comprising a light bar with multiple LEDs and an image projector, both electrically connected to a control module, which illuminates the underbody area and projects images onto the ground, synchronized with interior map lights activation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a light assembly is added to illuminate the underbody area and project images, then exterior illumination and image projection are enhanced, but device complexity increases
Solution Approach 1:
The patent combines the light bar with illumination function and the image projector with projection function into a single integrated light assembly unit that is assembled to the underbody of the vehicle. This merging of multiple functional components into one assembly enhances exterior illumination and image projection capabilities while managing device complexity through unified integration.
2Adaptability or versatility
If multiple light sources and control modules are integrated, then image projection and illumination coordination is improved, but ease of manufacture decreases
Solution Approach 1:
The light assembly is segmented into distinct functional modules: a light bar containing multiple light sources for illumination, and a separate image projector module with its own light source and projection optics. Each module can be manufactured independently and then assembled together, improving coordination capability while maintaining ease of manufacture through modular construction.
3Area of stationary object
If the image projector is fitted to the light bar with different emission angles, then illumination coverage is improved, but manufacturing precision requirements increase
Solution Approach 1:
The light bar and image projector are designed with different local emission angles optimized for their specific functions. The light bar emits light at angles optimized for underbody illumination coverage, while the image projector is angled separately to optimize projection onto the ground. This local quality differentiation improves overall illumination coverage while the modular design helps manage manufacturing precision requirements.
