Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the display screen size is increased to provide a larger displaying surface, then the displaying area is improved, but the device becomes bulky and difficult to carry
Solution Approach 1:
The display device is divided into multiple detachable display modules that can be separated and carried independently. Each module contains a complete display system with flexible substrates, rigid substrates, and liquid crystal layers, allowing the total displaying area to be distributed across multiple portable units rather than requiring a single large bulky device.
Solution Approach 2:
The invention transitions from a single-plane display to a multi-dimensional configuration where multiple display modules can be arranged in different spatial configurations (side-by-side, stacked, or at angles). This allows the displaying area to expand in multiple dimensions while each individual module remains compact and portable.
2Adaptability or versatility
If a single displaying surface is used to simplify the device structure, then the device complexity is reduced, but the device cannot accommodate multiple viewers' needs for different images simultaneously
Solution Approach 1:
The display system is segmented into multiple independent display modules, each capable of displaying different content simultaneously. This segmentation allows multiple viewers to watch different programs or images on different modules at the same time, while each module maintains a relatively simple individual structure.
Solution Approach 2:
Each display module is designed as a universal unit that can function independently or be combined with other modules. The modules can be configured in various arrangements (side-by-side for multiple viewers, stacked for different orientations, or at angles for different viewing positions), providing multi-functionality without requiring complex integrated designs.
3Ease of operation
If the liquid crystal display is made foldable to improve portability, then the ease of carrying is improved, but the manufacturing complexity increases
Solution Approach 1:
The foldable display is segmented into multiple rigid substrates connected by flexible substrates, creating hinge-like joints between modules. This segmentation allows the display to be folded into compact configurations for portability while each rigid substrate can be manufactured using standard rigid substrate manufacturing processes, avoiding the need to manufacture entire large-area flexible displays in one piece.
Solution Approach 2:
Flexible substrates are used as connection elements between rigid display modules, enabling the rigid structures to be joined in folded configurations. The flexible substrates act as hinges that allow bending and folding while maintaining electrical and mechanical connections, combining the rigidity needed for stable display surfaces with the flexibility needed for portability.

AI summary
A foldable liquid crystal display device and a method for manufacturing the foldable liquid crystal display device are provided. The foldable liquid crystal display device includes displaying sections, each of which includes a pair of rigid substrates. The displaying sections are connected together with flexible substrates. Folding sections are provided between the displaying sections so that the flexible substrates are foldable along the folding sections to have the displaying sections stacked on each other. Thus, expanding the displaying sections allows for expansion of a displaying area of the liquid crystal display device and folding the displaying sections allows for reduction of a space occupied by the liquid crystal display device to facilitate carrying. By adopting different display modes for different ones of the displaying sections, application scenarios of the liquid crystal display device can be made versatile.
