Solution Overview
Problem
Vehicle lamps lack aesthetic appeal and effective light distribution, limiting their ability to attract consumer attention and enhance the vehicle's design quality.
Innovation Solution
A sequential lighting device featuring a linearly extended housing with a rotatable cylindrical light guide and emission portion, where light is totally reflected and emitted through a series of optics arranged spirally or linearly, creating a sequential lighting effect by changing the emission position with rotation, and a bezel with linear light emission holes to enhance light projection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a conventional lamp structure is used, then the lamp can provide basic lighting function, but the aesthetic appearance and light distribution are limited
Solution Approach 1:
The patent applies the dynamics principle by implementing a rotatable light guide that enables sequential lighting effects. The light guide rotates to sequentially expose different emission portions, transforming a static lighting system into a dynamic one that provides both functional illumination and aesthetic sequential lighting effects, thereby resolving the contradiction between basic lighting function and aesthetic appearance.
Solution Approach 2:
The patent applies segmentation by dividing the light guide into multiple emission portions arranged along its length. Each emission portion corresponds to a specific light-emitting region, allowing the light guide to be segmented into functional zones that can be sequentially activated through rotation, improving both light distribution and aesthetic appearance.
2Shape
If multiple light sources are used to achieve sequential lighting effect, then the aesthetic appeal is improved, but the cost and device complexity increase
Solution Approach 1:
The patent applies the universality principle by designing a single light guide that performs multiple functions: it guides light from the light source, creates sequential lighting effects through rotation, and distributes light to multiple emission portions. This multi-functional design eliminates the need for multiple separate light sources while achieving the desired aesthetic appeal, thereby reducing device complexity and cost.
Solution Approach 2:
The patent applies the intermediary principle by introducing a rotatable light guide as a mediator between the single light source and the multiple emission portions. The light guide acts as an intermediary that distributes and sequences the light from one source to multiple locations, achieving sequential lighting effects without requiring multiple light sources, thus reducing complexity while maintaining aesthetic appeal.
3Duration of action of moving object
If the light guide structure is made complex to achieve sequential lighting, then the lighting effect is improved, but the manufacturing difficulty and cost increase
Solution Approach 1:
The patent applies the merging principle by combining the light guiding function and the sequential lighting function into a single integrated light guide structure. The light guide simultaneously performs light transmission and sequential light emission through its rotation, eliminating the need for separate mechanical components and complex assembly processes, thereby improving manufacturability while maintaining the sequential lighting effect.
4Productivity
If the lamp design focuses on light concentration, then the lighting efficiency is improved, but the aesthetic design flexibility is limited
Solution Approach 1:
The patent applies dynamics by implementing a rotatable light guide that can dynamically adjust light distribution patterns. The system maintains high lighting efficiency through effective light guidance while gaining design flexibility through the ability to create various sequential lighting patterns and effects, thereby resolving the contradiction between lighting efficiency and design flexibility.
