Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a conventional 3D display device uses specialized components and complex configurations to create a 3D image without glasses, then the 3D image display capability is achieved, but the manufacturing cost and device complexity increase
Solution Approach 1:
The patent applies universality by using a standard backlight module originally designed for ordinary 2D display devices in the 3D display device. This allows the backlight module to serve multiple functions - it can be used in both conventional 2D displays and in the 3D display configuration, reducing the need for specialized components and lowering manufacturing costs while maintaining 3D image display capability

Solution Approach 2:
The patent applies copying by replicating the structure and components of ordinary display devices in the 3D display device. By using the same standard backlight module, frame structures, and assembly methods as conventional displays, the manufacturing process can be copied from existing production lines, significantly reducing development costs and enabling mass production
3Ease of operation
If the spacing between display panels is not constant, then assembly flexibility is improved, but image accuracy deteriorates
Solution Approach 1:
The patent applies preliminary action by pre-forming recesses in the frame at precise positions before assembly. These recesses are created during frame manufacturing with exact dimensions and locations, ensuring that when the display panels are assembled, they automatically achieve the required constant spacing. This preliminary positioning feature guarantees image accuracy while maintaining assembly flexibility
Solution Approach 2:
The patent applies the intermediary principle by introducing recesses as mediating structures between the frame and display panels. These recesses act as intermediaries that precisely control the spacing between panels while allowing flexible assembly. The recesses serve as a buffer and positioning mechanism that ensures constant spacing is maintained throughout the device
