Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional vehicle lamps are used, then manufacturing is simple, but design differentiation and aesthetic appeal are limited
Solution Approach 1:
The lighting apparatus is divided into multiple light guides, each corresponding to a divergence lens, arranged along the circumference of the light distribution space. This segmentation allows independent control and design of each lighting element while maintaining overall system functionality, enabling diverse design patterns and aesthetic effects.
Solution Approach 2:
The patent introduces a third dimension of depth perception by arranging light guides and divergence lenses to create linear lighting images that extend in the front-rear direction. The infinite reflection between half mirror and mirror adds another layer of spatial dimension, transforming traditional two-dimensional lamp surfaces into three-dimensional visual experiences.
2Illumination intensity
If multiple light guides and lenses are used, then three-dimensional lighting effect is achieved, but manufacturing complexity increases
Solution Approach 1:
Multiple light guides and divergence lenses are integrated into a unified optical system with standardized mounting structures. The light guides are arranged along the circumference of the light distribution space with regular spacing, allowing modular assembly and simplified manufacturing processes despite the multi-component design.
Solution Approach 2:
The divergence lenses serve multiple functions: they diverge light from light guides, create linear lighting images, and work in conjunction with mirrors to produce infinite reflection effects. This multi-functionality reduces the need for separate components, simplifying the overall manufacturing process.
3Shape
If light guides and divergence lenses are used, then linear lighting image with depth is created, but component quantity increases
Solution Approach 1:
The optical components are nested within a compact light distribution space. Light guides are positioned to correspond with divergence lenses, which are in turn arranged within the circumferential boundary of the light distribution space. This nested arrangement maximizes spatial utilization and minimizes the overall footprint of the lighting apparatus.
Solution Approach 2:
The light guides have a linear rod shape with thin profile, allowing them to be closely spaced and integrated into the compact light distribution space without requiring excessive volume. This thin-film-like structure enables high component density while maintaining design flexibility.

Function Achieved in This Case
The apparatus enhances design freedom and aesthetic appeal by creating a three-dimensional lighting image with an infinite sense of depth, reducing the number of components and simplifying manufacturing, while providing a unique and differentiated lighting effect for vehicle lamps.
Implementation Method 1
a total reflection part formed on the other side of the circumferential portion of the light guide body, the other side being toward an outside of the light distribution space, and configured to totally reflect the light toward the inward emission part
Implementation Method 2
one or more divergence lenses disposed on the light distribution space so as to extend along the light guides, and configured to diverge the lights, which are incident from the light guides
Implementation Method 3
a mirror disposed on the other side of the divergence lenses so as to face the divergence lenses, and configured to reflect the lights, which are diverged by the divergence lenses, between the half mirror and the mirror
