Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Noise is generated during the unfolding and folding of foldable mobile terminals due to asynchronous movement between the rotating shaft mechanism and the flexible screen, leading to poor product quality and user experience.
Innovation Solution
A foldable mobile terminal design that incorporates a gasket between the rotating shaft mechanism and the flexible screen, with a connection region fixedly connected to the rotating member and a non-connection region that slides, reducing the gap and deformation, thereby minimizing noise and improving assembly precision.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If the rotating shaft mechanism and flexible screen are directly connected without a gasket, then the structure is simple, but noise is generated during folding and unfolding due to asynchronous movement and gaps
Solution Approach 1:
A gasket is introduced as an intermediary component between the rotating shaft mechanism and the flexible screen. The gasket includes a connection region fixedly connected to the rotating member and a non-connection region that slides relative to the rotating shaft body, serving as a mediator to eliminate gaps and reduce noise during folding and unfolding operations
2Manufacturing precision
If the gasket is fully fixed to the rotating shaft mechanism, then assembly precision is improved, but the flexible screen deformation is restricted causing increased noise
Solution Approach 1:
The gasket is segmented into two functional regions: a connection region that is fixedly connected to the rotating member to provide stable support and improve assembly precision, and a non-connection region that can slide relative to the rotating shaft body to accommodate flexible screen deformation and reduce noise
Solution Approach 2:
Different regions of the gasket have different properties: the connection region provides rigid fixed connection for precision, while the non-connection region provides flexible sliding capability for noise reduction, allowing each part to perform its specific function optimally
3Manufacturing precision
If the gap between the rotating shaft mechanism and flexible screen is reduced, then assembly precision is improved, but the flexible screen deformation capability is restricted
Solution Approach 1:
The gasket transitions from a static fixed connection to a dynamic system where the non-connection region can slide relative to the rotating shaft body, allowing the gap to be reduced for precision while maintaining deformation capability through controlled sliding movement

AI summary
A foldable mobile terminal is provided. The foldable mobile terminal may be a foldable device such as a mobile phone, a tablet computer, or a notebook computer. In embodiments of this disclosure, a gasket is arranged between a flexible screen and a rotating shaft mechanism. The gasket includes a connection region and a non-connection region in an arrangement direction of a rotating shaft body and a rotating member. The non-connection region is slidably arranged between the rotating shaft body and the flexible screen. When the flexible screen is folded or unfolded, a bending portion of the flexible screen first comes into contact with the non-connection region, and a spacing between the flexible screen and the non-connection region is small, which can reduce abnormal noise.
