Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional auxiliary elements are used to support bendable areas, then the structure is simple, but the connecting relationships are insufficient and components separate easily when bent
Solution Approach 1:
The patent combines multiple supporting components (elastic assembly, connecting blocks, connecting pieces, strengthening bar) into an integrated stretching and folding assembly. The connecting pieces connect adjacent connecting blocks, and the strengthening bar is fixed on the elastic assembly, creating a unified structure that prevents separation while maintaining manageable complexity through functional integration.
Solution Approach 2:
The auxiliary elements are pre-configured in the bendable area before the flexible display panel is bent. The elastic assembly, connecting blocks, and strengthening bar are positioned and connected in advance, so that when bending occurs, the components work together immediately without separation or misalignment.
2Strength
If conventional auxiliary elements are used, then the structure is simple, but the strength ability is insufficient and the flexible display panel is not smooth when bent
Solution Approach 1:
The patent employs an elastic assembly (providing flexibility) combined with a strengthening bar (providing rigidity and strength). This composite structure combines materials with different mechanical properties to achieve both smooth bending capability and sufficient strength, preventing panel deformation while maintaining flexibility.
Solution Approach 2:
The auxiliary support structure is divided into multiple segments: elastic assembly, connecting blocks, connecting pieces, and strengthening bar. This segmentation allows each component to perform its specific function optimally while collectively providing enhanced bending strength and smoothness without excessive overall complexity.
3Reliability
If the flexible display panel is bent without sufficient auxiliary support, then the structure is simple, but the bending quality is poor and user experience deteriorates
Solution Approach 1:
The elastic assembly changes its physical parameters (elasticity, flexibility) to adapt to bending conditions. The connecting pieces allow relative movement between connecting blocks, enabling the structure to adjust its configuration dynamically during bending operations, ensuring smooth and reliable bending performance.

AI summary
A display device is provided and includes a flexible display panel, a middle frame, and a stretching and folding assembly. The flexible display panel has a bendable area. The middle frame encompasses a periphery of the flexible display panel. The stretching and folding assembly is disposed in the bendable area and includes an elastic assembly, connecting blocks, and connecting pieces. The elastic assembly covers the bendable area and an area of the middle frame corresponding to the bendable area. The connecting blocks are disposed at two ends of the elastic assembly. Each connecting piece is disposed between two adjacent ones of the connecting blocks to connect the two adjacent ones of the connecting blocks and configured to cause the connecting blocks to drive, when the flexible display panel is bent, the area of the middle frame corresponding to the bendable area to be bent.
