Solution Overview
Problem
Existing flexible display devices have structurally complex driving and support parts that occupy a large space, hindering the goal of lightening and thinning.

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the driving part and support part are separately arranged, then the display module can be supported and driven, but the structural complexity increases and space occupation increases
Solution Approach 1:
The patent combines the driving part and support part into an integrated mechanism. The support bracket serves both as a support structure and as part of the driving mechanism, eliminating the need for separate driving part and support part arrangements. This integration reduces structural complexity while maintaining the necessary support and driving functions.
Solution Approach 2:
The support bracket is designed to perform multiple functions: it provides structural support for the display module, guides the sliding motion, and participates in the driving mechanism. This multi-functionality reduces the number of separate components needed, thereby reducing overall structural complexity and space occupation.
2Reliability
If the driving part and support part are separately arranged, then the display module can be supported and driven, but the space occupied increases
Solution Approach 1:
By merging the driving part and support part into an integrated mechanism, the patent reduces the total space required. The support bracket and driving mechanism share the same spatial envelope, eliminating the need for separate spaces that would be required if they were arranged separately.
Solution Approach 2:
The driving mechanism is nested within the support bracket structure. The movable part of the driving mechanism is positioned within the space defined by the support bracket, allowing one component to occupy the space of another rather than requiring additional space for separate components.
3Productivity
If a traditional driving mechanism is used, then the display module can be driven, but the stroke requirement increases
Solution Approach 1:
The patent employs a dynamic mechanism where the support bracket can rotate and the connecting member can swing. This dynamic approach allows the driving mechanism to achieve the required display module movement with smaller individual strokes, as the motion is distributed across multiple degrees of freedom rather than requiring a single long linear stroke.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The device achieves efficient sliding and support with minimal space requirements, reducing the stroke demand on the driving mechanism and enhancing the flexibility and compactness of the display.
Implementation Method 1
