Bendable Device Supporting Sheet Assembly Disassembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bendable devices face damage during disassembly due to the rigidity of their flexible screens, which limits reliable disassembly and assembly processes.
Innovation Solution
A bendable device design incorporating a flexible screen connected via a supporting sheet assembly to a housing assembly, utilizing a combination of rigid and flexible sheets, adhesive layers, and a bendable member to facilitate disassembly by separating the supporting sheet assembly from the housing, thereby minimizing damage to the flexible screen.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the flexible screen is made rigid to maintain structural integrity, then the device stability is improved, but the flexibility and bendability of the screen deteriorates
Solution Approach 1:
The supporting sheet assembly is divided into a rigid first sheet and a flexible second sheet. The rigid first sheet provides structural support and stability, while the flexible second sheet allows the screen to bend. This segmentation resolves the contradiction by distributing different functional requirements to different components.
Solution Approach 2:
Different regions of the supporting sheet assembly have different mechanical properties. The first sheet (or specific regions thereof) is made rigid to maintain structural integrity, while the second sheet is made flexible to enable bending. This local differentiation of material properties allows the device to simultaneously achieve both stability and flexibility.
2Device complexity
If the flexible screen is directly connected to the housing assembly, then the device complexity is reduced, but the reliability of disassembly deteriorates due to screen damage
Solution Approach 1:
The supporting sheet assembly serves as an intermediary component between the flexible screen and the housing assembly. It provides a detachable connection interface, allowing the screen to be connected to or separated from the housing without direct attachment. This intermediary structure enables reliable disassembly while maintaining a relatively simple overall connection system.
3Strength
If the supporting sheet assembly is made fully rigid, then the structural support is improved, but the bendability of the flexible screen deteriorates
Solution Approach 1:
The supporting sheet assembly is segmented into a rigid first sheet and a flexible second sheet. The rigid first sheet provides the necessary structural support and strength, while the flexible second sheet enables the screen to bend. This segmentation allows the device to achieve both strong structural support and bendability simultaneously.
Solution Approach 2:
The supporting sheet assembly combines rigid and flexible materials in a composite structure. The rigid first sheet and flexible second sheet work together as a composite system, where each material contributes its advantageous properties. This composite approach resolves the contradiction between strength and bendability.

AI summary
A bendable device is provided according to the present disclosure. The bendable device includes a bendable flexible screen, a supporting sheet assembly, and a housing assembly. The flexible screen includes a display surface and a rear surface opposite to the display surface. The supporting sheet assembly is sandwiched between the rear surface of the flexible screen and the housing assembly. The flexible screen is connected to the housing assembly via the supporting sheet assembly. The flexible screen is connected to the supporting sheet assembly, such that when disassembling the bendable device, only the supporting sheet assembly needs to be disassembled from the housing, thereby improving reliability of disassembly.
