Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a curvature-changing member with wire mechanism is added to adjust display curvature, then immersive effect is improved, but device complexity increases
Solution Approach 1:
The curvature-changing member is segmented into discrete functional components: wire guiders positioned at specific intervals, wire stoppers attached at predetermined positions, and movement control parts. This segmentation allows each component to perform its specific function independently while contributing to the overall curvature adjustment capability, resolving the contradiction by making the complex system modular and manageable.
Solution Approach 2:
The system employs dynamic elements including a movable wire that can be tensioned and relaxed, wire stoppers that can engage and disengage from wire guiders, and movement control parts that actively adjust positions. This dynamic design enables curvature adjustment while maintaining structural integrity, addressing the contradiction between adaptability and complexity.
2Manufacturing precision
If wire stoppers are positioned closely to limit wire movement, then curvature control precision is improved, but manufacturing complexity increases
Solution Approach 1:
The patent employs parameter changes by varying the intervals between wire stoppers and wire guiders to achieve different curvature control precisions. By adjusting these spatial parameters during design, the system achieves precise curvature control without requiring complex manufacturing processes, as the precision is achieved through parameter optimization rather than manufacturing complexity.
3Adaptability or versatility
If multiple wire guiders and stoppers are used to control curvature, then curvature adjustment range is improved, but device complexity increases
Solution Approach 1:
The wire mechanism serves multiple functions simultaneously: it provides tensioning force, defines curvature through its path constrained by wire guiders, and limits movement through wire stoppers. This multi-functionality allows the system to achieve wide curvature adjustment range without proportionally increasing the number of separate mechanical parts, as each component performs multiple roles.
Solution Approach 2:
The wire acts as an intermediary element that transmits force from the movement control parts to the display module, enabling curvature adjustment. The wire guiders and stoppers serve as intermediaries that constrain and guide the wire's movement, thereby controlling the curvature. This intermediary approach allows complex curvature control with relatively simple mechanical parts.

AI summary
A display apparatus includes a display module including a flexible display panel, a curvature-changing member configured to adjust a curvature of the display module, and a bottom chassis in which is disposed the display module and the curvature-changing member. The curvature-changing member includes a wire, a first movement control part which moves the wire, a plurality of wire guiders through which the wire passes, disposed at predetermined intervals in a moving path of the wire to guide the moving path of the wire; and a plurality of wire stoppers which is coupled to the wire at predetermined intervals along a length of the wire limiting the movement of the wire along the moving path. In an unbent state of the curvature-changing member, intervals between adjacent wire guiders among the plurality of wire guiders are larger than intervals between adjacent wire stoppers among the plurality of wire stoppers.
