Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a conventional dual-shaft mechanism is employed to provide bending operation space for the flexible screen, then the operation mode variety is improved, but the device volume and moving space occupation increase
Solution Approach 1:
The patent combines the dual-shaft mechanism with a pivot shaft structure into a single integrated pivot shaft device. The operation arm serves both as a pivot component and as part of the dual-shaft mechanism, eliminating the need for separate components. This merging reduces the overall device volume while maintaining the ability to provide multiple operation modes for the flexible screen.
Solution Approach 2:
The patent implements a nested structure where the guide section is disposed on the operation arm and the guiding section is disposed between the operation arm and the fixing seat. The reciprocally movable bolt is positioned within the guide section, creating a compact nested arrangement. This nesting allows the dual-shaft mechanism to be contained within the pivot shaft structure, reducing the moving space occupation while maintaining operation mode variety.
2Adaptability or versatility
If multiple rotary shafts, links, gears, and connection components are assembled to transmit power for synchronous rotation, then the synchronous rotation function is improved, but the structure complexity and assembly difficulty increase
Solution Approach 1:
The patent extracts and eliminates unnecessary intermediate components such as separate links, gears, and connection components from the conventional dual-shaft mechanism. By directly integrating the power transmission function into the pivot shaft structure itself, the design achieves synchronous rotation without requiring multiple separate parts. This extraction simplifies the overall structure while maintaining the synchronous rotation function.
Solution Approach 2:
The pivot shaft structure is designed to perform multiple functions simultaneously: it serves as the pivot axis, provides the dual-shaft mechanism for synchronous rotation, and incorporates the guide and guiding sections for controlled movement. This multi-functionality eliminates the need for separate dedicated components for each function, thereby reducing structure complexity while maintaining the synchronous rotation capability.
3Ease of manufacture
If conventional pivot shaft devices are designed with standard components and connection forms, then the manufacturing standardization is improved, but the space occupation and appearance aesthetics deteriorate
Solution Approach 1:
The patent employs dynamic design elements including the reciprocally movable bolt that can move between the guide section and the guiding section, and the operation arm that can rotate around the shaft pillar. These dynamic components allow the structure to adapt to different operational states while maintaining a compact form factor. The dynamic nature of the design enables minimized space occupation while still allowing for standardized manufacturing of individual components.

AI summary
A complex moving/rotating pivot shaft device is applicable to a double-screen or flexible screen to minify the assembling/moving space of the components. The complex moving/rotating pivot shaft device includes an assembly of a fixing seat and a moving module. The moving module includes an operation arm, a guide section disposed on the operation arm and a bridge unit disposed between the operation arm and the fixing seat. The bridge unit has a shaft pillar, a reciprocally movable bolt and a guiding section in cooperation with the guide section, whereby the operation arm can move along the guiding section to reach a set position. Thereafter, the operation arm can rotate around the shaft pillar of the bridge unit to achieve opening/closing effect.
