Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing light emitting devices for motor vehicles lack the capability to create three-dimensional or dynamic lighting effects in a simple and cost-effective manner, failing to provide personalized and aesthetically appealing lighting patterns.
Innovation Solution
A light distribution element comprising petal-shaped and annular convexes formed as lenticular gratings, where the patterns generated by these convexes on the light entrance and exit sides interact to produce a stereoscopic and dynamic lighting effect, allowing for personalized lighting patterns and effects through adjustable positioning and rotation of the deflecting portions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If existing lighting devices use simple light sources without complex optical elements, then the device complexity is low and manufacturing cost is reduced, but the lighting effect lacks three-dimensional or dynamic optical effects and personalized patterns
Solution Approach 1:
The light distribution element is divided into multiple independent light deflecting portions (first and second types) that can be separately designed and positioned. Each portion creates specific light patterns, and their superposition forms complex three-dimensional lighting effects. This segmentation allows achieving sophisticated lighting effects without requiring a single complex optical element.
Solution Approach 2:
The patent employs nested optical elements where the first light deflecting portions are positioned on one side of the light source and the second light deflecting portions are positioned on the other side, with light passing through both layers. This nested arrangement allows multiple optical functions to be combined in a compact structure, achieving three-dimensional lighting effects without proportionally increasing device complexity.
2Adaptability or versatility
If multiple light deflecting portions are used to create personalized lighting patterns and three-dimensional effects, then the lighting effect quality is improved, but the device complexity and manufacturing cost increase
Solution Approach 1:
The light distribution element allows for adjustable positioning and rotation of the light deflecting portions. This dynamic configurability enables the same physical element to generate different lighting patterns and personalization effects without requiring multiple fixed-pattern elements, thereby reducing device complexity while maintaining versatility.
Solution Approach 2:
Each light deflecting portion is designed to perform multiple functions: they can be positioned at different locations, rotated to different angles, and combined in various configurations to create diverse lighting patterns. This multi-functionality allows a limited set of optical elements to achieve personalized lighting effects that would otherwise require many different specialized elements.
3Illumination intensity
If complex optical patterns are formed using traditional methods, then the lighting effect quality is improved, but the manufacturing process becomes more difficult and costly
Solution Approach 1:
The light distribution element can be implemented as a thin, flexible component with light deflecting portions formed on transparent or translucent substrates. This thin-film approach simplifies manufacturing compared to traditional bulky optical elements, allows for easier integration into vehicle lighting systems, and enables mass production techniques while maintaining the capability to create complex three-dimensional lighting effects.
