Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the display panel and module cover are rolled on a roller to enable flexibility and compact storage, then the device achieves ultra-thin profile and portability, but the panel and module cover become vulnerable to damage from external shocks and vibrations during rolling and unrolling
Solution Approach 1:
The patent applies beforehand cushioning by installing buffer members at predetermined locations where shocks and vibrations may occur during rolling and unrolling. The buffer members are positioned to cushion the panel and module cover before damage can occur, preventing direct impact forces from reaching critical components.
Solution Approach 2:
The buffer members act as intermediaries between the external shock sources and the vulnerable components (panel and module cover). These buffer members absorb and dissipate impact forces, mediating the transmission of harmful forces during the rolling and unrolling operations.
2Volume of moving object
If the display panel is made flexible to enable rolling, then the device achieves compact form factor, but internal structures may collide with each other during rolling and unrolling movements
Solution Approach 1:
The patent positions buffer members in advance at locations where internal structural collisions may occur during rolling and unrolling. This beforehand cushioning prevents internal components from directly colliding by providing cushioning elements at potential impact zones before the collision can happen.
3Reliability
If buffer members are added to protect against shocks and vibrations, then damage resistance improves, but device complexity and manufacturing cost increase
Solution Approach 1:
The patent applies local quality by placing buffer members only at specific critical locations where shocks and vibrations are most likely to cause damage, rather than uniformly throughout the entire device. This targeted approach provides necessary protection while minimizing the addition of components and maintaining relatively simple device architecture.
