Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a flexible display device is designed to be slidable or foldable for improved portability, then ease of operation is improved, but the device may deform when slid or folded, reducing reliability
Solution Approach 1:
The support structure is divided into multiple segment members that can relatively move with respect to each other during sliding or folding operations. This segmentation allows the device to change configuration for portability while each segment maintains its structural integrity, preventing overall device deformation
Solution Approach 2:
Different filling members with different elastic moduli are placed at different locations under the plate. First filling members with higher elastic modulus provide rigid support in areas requiring stability, while second filling members with lower elastic modulus provide flexible support in areas requiring deformation accommodation, thus preventing device deformation while enabling portability
2Reliability
If filling members with different elastic moduli are used to prevent deformation, then reliability is improved, but device complexity increases due to multiple components
Solution Approach 1:
The patent applies local quality by positioning filling members with different elastic moduli at specific locations based on the structural requirements of each area. This targeted approach achieves deformation prevention where needed without unnecessarily complicating the entire device structure
Solution Approach 2:
The patent uses composite material principles by combining filling members with different elastic moduli in a single support structure. This creates a composite system that leverages the advantages of both rigid and flexible materials to prevent deformation while maintaining structural coherence
