Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a large number of light sources or additional structures are used to form a three-dimensional image, then the three-dimensional feeling is improved, but costs are increased
Solution Approach 1:
The patent introduces a reflection part as an intermediary element that redirects light from the light source to create three-dimensional lighting patterns. Instead of using multiple light sources, a single light source combined with the reflection part achieves the desired effect, thereby reducing device complexity while maintaining illumination quality
Solution Approach 2:
The reflection part creates virtual images of the light source by reflecting light, effectively copying the light source's appearance from different angles. This allows the formation of three-dimensional lighting patterns without physically installing multiple light sources, reducing both cost and device complexity
2Illumination intensity
If conventional structures are used to create three-dimensional lighting patterns, then the lighting effect is achieved, but manufacturing cost increases
Solution Approach 1:
The patent changes the optical parameters of the lighting system by introducing a reflection part with specific reflective properties. This allows the same light source to produce different lighting patterns and three-dimensional effects without changing the physical structure or adding multiple light sources, thereby reducing manufacturing costs
Solution Approach 2:
The reflection part serves multiple functions: it redirects light to create three-dimensional patterns, enhances illumination intensity, and enables various lighting effects with a single light source. This multi-functionality reduces the need for additional components, simplifying manufacturing and reducing costs

Implementation Method 1
a lamp for a vehicle that implements a disparity perspective through refraction and reflection of side light irradiated by a light source
Implementation Method 2
a reflection part installed on a rear side corresponding to an opposite direction to a front side that faces the lens part from the light source part to be spaced apart from the light source part, and that reflects the light irradiated from the light source part to the front side
