Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a fixed installation structure is used for display devices, then structural stability is improved, but adaptability and space efficiency deteriorate
Solution Approach 1:
The patent applies the dynamics principle by transforming the fixed installation structure into a movable and adjustable one. The display device incorporates a roll-up mechanism with a cord that can be rolled up and down, allowing the display panel to be dynamically adjusted between extended and retracted positions. This enables the structure to adapt to different spatial requirements while maintaining stability during operation.
Solution Approach 2:
The patent applies segmentation by dividing the support structure into multiple components: a fixing portion, multiple supporting members arranged at intervals, and a cord connection system. This segmentation allows each component to perform its specific function independently while contributing to the overall adaptability of the display device installation system.
2Area of moving object
If larger display sizes are implemented, then display area is improved, but space efficiency and storage capability deteriorate
Solution Approach 1:
The patent applies the nesting principle through the roll-up mechanism where the cord can be rolled up into a compact form when not in use. This allows the large display area to be collapsed into a small storage space, effectively solving the contradiction between large display size and space efficiency for storage and transport.
Solution Approach 2:
The patent applies dimensionality change by transitioning the display device from a two-dimensional extended state to a compact one-dimensional rolled-up state. The cord connects the fixing portion to the supporting members, enabling the display panel to be folded or rolled along the cord's length, effectively reducing the volume occupied while maintaining the display area capability.
3Volume of moving object
If foldable structures are introduced, then space efficiency is improved, but reliability and electrical connectivity maintenance deteriorate
Solution Approach 1:
The patent applies the intermediary principle by introducing a cord as a mediator between the fixing portion and the supporting members. This cord serves as both a mechanical connector for the foldable structure and an electrical conduit that maintains power and signal connectivity during folding and unfolding operations, thereby preserving reliability while enabling space efficiency.
Solution Approach 2:
The patent applies flexible shells and thin films by using a flexible cord that can bend and flex during the folding and unfolding operations. This flexible cord maintains electrical connectivity throughout the range of motion, ensuring reliable operation while enabling the compact folded configuration for space-efficient storage.
