Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If two independent display panels are assembled in a back-to-back manner, then double-sided display functionality is achieved, but the overall device thickness increases
Solution Approach 1:
The patent merges two separate light guide plates into a single shared light guide plate that serves both display panels. This consolidation reduces the overall number of components and eliminates the need for separate light guiding structures for each panel, thereby reducing device thickness while maintaining double-sided display functionality
Solution Approach 2:
The shared light guide plate performs multiple functions: it guides light for the first display panel on one side and simultaneously guides light for the second display panel on the other side. This multi-functional design allows a single component to replace what would traditionally require two separate components, reducing overall device thickness
2Adaptability or versatility
If two independent display panels are assembled in a back-to-back manner, then double-sided display functionality is achieved, but power consumption increases
Solution Approach 1:
The patent combines the lighting functions for both panels into a single shared light guide plate system. This allows for more efficient light distribution and reduces redundant lighting components, thereby lowering overall power consumption while maintaining double-sided display capability
Solution Approach 2:
The shared light guide plate is designed to efficiently serve both display panels simultaneously, optimizing light utilization and reducing the total energy required to illuminate both sides compared to two independent systems
3Length of stationary object
If a shared light guide plate is used for both panels, then device thickness is reduced, but light distribution uniformity becomes more difficult to control
Solution Approach 1:
The light guide plate is divided into distinct first and second regions with different pattern designs. The first region contains a first pattern optimized for the first display panel, while the second region contains a second pattern optimized for the second display panel. This segmentation allows each region to be independently optimized for uniform light distribution to its respective panel
Solution Approach 2:
Different surface patterns are applied to different regions of the light guide plate. The first region has a first pattern specifically designed for optimal light distribution to the first panel, while the second region has a second pattern designed for the second panel. This local customization of pattern quality ensures uniform light distribution for each panel despite using a shared light guide plate

AI summary
A double-sided display device includes a first panel, a second panel, a light guide plate and a light source. The second panel is arranged opposite to the first panel. The light guide plate is arranged between the first panel and the second panel, and includes a main body portion including a first surface and a second surface, a first pattern arranged on the first surface, and a second pattern arranged on the second surface. The light source is arranged adjacent to the light guide plate. The first pattern is different from the second pattern.
