Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Slidable display devices suffer from defects such as distortion, scratching, and cracking due to external impacts during sliding operations.
Innovation Solution
A slidable display device design featuring a support member with transformable bars and a support plate, including patterned flexible portions to maintain consistent gaps and engage neighboring bars, preventing distortion and protecting against external impacts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the display panel is made flexible and slidable to enable foldable/rollable configurations, then the display screen can be enlarged or downsized, but the display panel becomes susceptible to distortion, scratching, and cracking during sliding operations
Solution Approach 1:
A flexible support plate is introduced beneath the display panel to provide structural support during sliding operations. This support plate acts as a protective shell that prevents distortion, scratching, and cracking while allowing the display panel to maintain its flexible, slidable configuration for foldable and rollable display modes
Solution Approach 2:
The flexible support plate serves as an intermediary element between the display panel and the external environment. It mediates the mechanical stresses during sliding operations, absorbing and distributing forces to prevent direct contact between external objects and the display panel, thereby preventing damage while preserving flexibility
2Adaptability or versatility
If the support structure is made transformable to enable sliding operations, then the display can change shapes, but the support structure becomes prone to external impacts and structural defects
Solution Approach 1:
The flexible support plate provides a protective underlying structure that maintains the transformable capabilities of the support structure while adding resistance to external impacts. The flexible nature of the support plate allows it to deform with the sliding motion while maintaining structural integrity and protecting against damage
3Ease of operation
If the display panel is exposed to the outside during folded configuration, then the display screen is accessible, but the display panel is vulnerable to external impacts and defects
Solution Approach 1:
The flexible support plate acts as a protective intermediary layer that is exposed during folded configurations. It provides a tough, impact-resistant surface that protects the display panel from external impacts while still allowing the display to be accessible and functional when in folded or rolled states
