Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Automotive exterior lighting technologies fail to provide both regulatory functionality and a unique, aesthetically pleasing appearance, particularly in creating uniformity and continuity among functionally separate lamps.
Innovation Solution
A projection device using one or more lenticular lenses positioned in front of a light source to generate a three-dimensional image, with the size, shape, and appearance altered by lens distances and orientations, and affected by the angle of observation, which can be incorporated into lamp assemblies to provide a unique and shifting lit appearance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If conventional automotive exterior lighting is used, then regulatory functions are provided, but a unique and aesthetically pleasing appearance with uniformity and continuity is not achieved
Solution Approach 1:
The patent combines multiple lenticular lenses with different optical characteristics into a single lighting assembly, merging their light distribution patterns to create a unified appearance with uniformity and continuity across functionally separate lamps while maintaining regulatory lighting functions
Solution Approach 2:
Different lenticular lenses are positioned at specific locations within the lighting assembly, each with tailored optical properties to achieve localized light distribution characteristics that collectively create the desired uniform and continuous appearance across the entire lighting component
2Shape
If lenticular lenses are added to create three-dimensional images and unique appearance, then aesthetic value and uniformity are improved, but device complexity increases
Solution Approach 1:
The lighting assembly is divided into multiple functional segments, each containing one or more lenticular lenses with specific optical characteristics. This segmentation allows independent optimization of each lens's contribution to the three-dimensional image while managing overall system complexity through modular design
Solution Approach 2:
The patent introduces a third dimension to the light distribution by using stacked lenticular lenses that create depth and three-dimensional imaging effects, transforming conventional two-dimensional light patterns into multi-dimensional visual displays that enhance aesthetic value
