Flexible Screen Sliding Rail and Reel Assembly for Compact Storage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current foldable screens struggle to provide satisfactory user experiences due to their large volume and limited flexibility in size adjustment, making them unsuitable for miniaturization and convenient use.
Innovation Solution
An electronic device with a housing assembly, sliding rail assembly, and reel assembly that allows the flexible screen to be extended and retracted, featuring a reel support, rotating shaft, and elastic member for winding and unwinding the screen, enabling convenient size adjustments and compact storage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a foldable screen is used to provide different display sizes, then screen size versatility is improved, but device volume increases making it unsuitable for miniaturization
Solution Approach 1:
The flexible screen is wound around a reel assembly, with the reel support nested within the housing assembly. The sliding rail allows the reel assembly to move in and out, enabling the screen to be compactly stored when not in use while maintaining access to full screen functionality when extended.
Solution Approach 2:
The screen transitions from a static fixed-size display to a dynamic adjustable display that can be extended and retracted. The sliding rail assembly enables dynamic movement of the reel, allowing the screen length to be adjusted based on user needs while keeping the device compact when retracted.
2Ease of operation
If the screen is made extendable and retractable, then portability is improved, but device complexity increases due to additional mechanisms
Solution Approach 1:
The elastic member automatically winds the flexible screen onto the reel when the sliding rail is moved, eliminating the need for manual winding operations. The system self-regulates the screen retraction through the elastic force, reducing operational complexity for the user.
Solution Approach 2:
The reel support is integrated with the housing assembly, and the sliding rail is coupled to both the housing and reel support, combining multiple structural elements into a unified mechanism that reduces the number of separate components while maintaining functionality.
Applied Scientific Principles
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 allows users to conveniently use screens of different sizes, improving user experience while maintaining a small volume and mass, making it easier to carry compared to traditional foldable screens.
Implementation Method 1
a rotating shaft rotatably connected to the reel support; and an elastic member connected to the rotating shaft, configured to rotate the rotating shaft

AI summary
An electronic device includes a housing assembly, a sliding rail assembly, a reel assembly and a flexible screen. The sliding rail assembly is assembled to the housing assembly and includes a sliding rail including opposite front and rear surfaces. The reel assembly is fixed to an edge of the sliding rail slidable outwards from the housing assembly. The flexible screen includes a winding end, and has a first part provided at the front surface of the sliding rail and fixed to the housing assembly, and a second part extendably and retractably wound around the reel assembly through the winding end. The sliding rail is able to extend the second part of the flexible screen from the reel assembly when slid outwards from the housing assembly and to retract the second part of the flexible screen to the reel assembly when slid towards the housing assembly from an outside.
