Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a light guide body is used to display multiple designs, then the display versatility is improved, but the energy consumption increases and display uniformity deteriorates
Solution Approach 1:
The light guide body is segmented into multiple light guide legs (first, second, third light guide legs) that independently guide light from different light sources (first, second, third guided-light sources) to different regions of the light exit portion. Each light guide leg has its own light entrance surface and guides light through separate paths, allowing multiple designs to be displayed simultaneously with reduced energy consumption per region.
Solution Approach 2:
Different regions of the light exit portion are assigned different reflection design portions (first, second, third reflection design portions) with specific optical properties tailored to their functions. The first reflection design portion reflects light in a first direction, the second reflects light in a second direction, and the third reflects light in a third direction, creating locally optimized display regions with uniform brightness and reduced energy consumption.
2Adaptability or versatility
If a light guide body is used to display multiple designs, then the display versatility is improved, but display uniformity deteriorates
Solution Approach 1:
The light guide body is divided into multiple independent light guide legs, each responsible for illuminating specific regions. This segmentation allows precise control over light distribution to different areas, ensuring uniform display quality across multiple design regions without compromising versatility.
Solution Approach 2:
Each region of the light exit portion has dedicated reflection design portions with specific reflective properties optimized for that region. The first reflection design portion, second reflection design portion, and third reflection design portion each create uniform illumination in their respective regions, achieving high display uniformity across multiple designs.
3Adaptability or versatility
If multiple light sources are used to illuminate different regions, then the display versatility is improved, but the device complexity increases
Solution Approach 1:
Multiple light guide legs and their associated light sources are merged into a single integrated light guide body structure. The first light guide leg, second light guide leg, and third light guide leg are combined with their respective light sources to form one cohesive device, reducing overall complexity while maintaining the ability to display multiple designs simultaneously.
Solution Approach 2:
The light guide body serves multiple functions: it guides light from multiple light sources, creates multiple reflection designs, and displays multiple patterns simultaneously. This multi-functionality reduces the need for separate devices for each function, simplifying the overall system while maintaining high display versatility.

Implementation Method 1
a first reflection design portion which reflects, in a first direction, a portion of the first light guided by the first light guide leg and a second reflection design portion which reflects, in the first direction, another portion of the first light guided by the first light guide leg
Data Source
AI summary
A display device including (i) a light source and (ii) a light guide body which guides light emitted by the light source, and includes: a light guide leg that guides the light entering through a light entrance surface; and a light exit portion connected to the light guide leg and including a reflection design portion which reflects, in a first direction, a portion of the light guided by the light guide leg and another reflection design portion which reflects, in the first direction, another portion of the light. When viewed in the first direction, the reflection design portion is disposed in a first region on a second direction side with respect to a connecting portion of the light exit portion connected to the light guide leg, and the other reflection design portion is disposed in a second region on a third direction side with respect to the connecting portion.
