Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a flexible display panel is used to enable curling and deployment, then portability and convenience are improved, but stability and positioning accuracy deteriorate due to machining and assembly errors in supporting structures
Solution Approach 1:
The supporting structure employs movable locking blocks that can dynamically transition between locked and unlocked positions. The locking blocks are guided to move along predetermined paths, enabling the structure to adapt between stable locked states and flexible unlocked states, resolving the contradiction between stability and adaptability
Solution Approach 2:
Guiding surfaces act as intermediaries between the locking blocks and supporting strips. These guiding surfaces ensure precise movement paths for the locking blocks, compensating for machining and assembly errors, thereby maintaining positioning accuracy and stability while enabling flexible deployment
2Reliability
If supporting strips are used to maintain display panel position, then stability is improved, but flexibility and ease of curling deteriorate due to rigid constraints
Solution Approach 1:
The supporting structure transitions from a static rigid design to a dynamic system with movable locking blocks. When unlocked, the structure allows free curling motion; when locked, it provides stable positioning. This dynamic characteristic resolves the contradiction between stability and ease of operation
Solution Approach 2:
The continuous supporting structure is segmented into multiple supporting strips with individual locking blocks. This segmentation allows localized locking and unlocking, enabling the display panel to curl in specific regions while maintaining stability in locked regions, thus improving ease of operation without sacrificing overall stability
3Ease of manufacture
If traditional supporting structures are used, then manufacturing simplicity is maintained, but positioning precision deteriorates due to machining and assembly errors
Solution Approach 1:
Guiding surfaces serve as intermediaries that compensate for machining and assembly errors. By providing predetermined movement paths, the guiding surfaces ensure that locking blocks achieve accurate positioning even when there are variations in component dimensions, thus improving manufacturing precision without significantly complicating the manufacturing process
Solution Approach 2:
The design incorporates adjustable and tolerant parameter ranges in the guiding surfaces and locking block dimensions. By optimizing these parameters, the system achieves high positioning accuracy while maintaining ease of manufacture through standard manufacturing processes and materials
