Mobile Terminal Spring Mechanism for Flexible Display Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile terminals with flexible displays face challenges in maintaining structural integrity and protecting internal components when expanded, as the flexible display covers both front and rear faces, making it difficult to arrange user input units, interfaces, and antennas in a compact manner.
Innovation Solution
A mobile terminal design featuring a first and second frame that move relative to each other, a central bracket, and a spirally wound spring that unwinds to cover exposed portions when the terminal is extended, ensuring the flexible display is supported and internal components are protected, allowing for user input, interface, and antenna placement on vertical sides.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of moving object
If the flexible display is expanded to cover front and rear faces, then the display area is increased, but the structural integrity and protection of internal components deteriorates
Solution Approach 1:
The display is divided into a first region fixed to the first frame and a second region coupled to the movable second frame. This segmentation allows the display to be expanded while maintaining structural support through the frame structure, resolving the contradiction between increased display area and structural integrity.
Solution Approach 2:
A support structure including a central bracket and spring is introduced as an intermediary between the flexible display and the frame. The spring provides elastic support to maintain structural integrity while allowing the display to expand and contract, protecting internal components during size changes.
2Adaptability or versatility
If the flexible display is made deformable to vary size, then the adaptability is improved, but the protection of internal components worsens
Solution Approach 1:
The second frame is designed to move relative to the first frame in the first direction, enabling dynamic size adjustment. The spring provides dynamic support that adapts to the changing configuration, allowing the terminal to vary in size while protecting internal components from exposure during deformation.
3Device complexity
If the terminal structure is made compact, then the device complexity is reduced, but the arrangement of user input units and interfaces becomes difficult
Solution Approach 1:
The support structure extends in the second direction (thickness direction) to provide coverage. By utilizing the thickness dimension, the spring and central bracket can cover exposed portions without increasing the footprint in the first direction, enabling compact arrangement while maintaining ease of operation.

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 design effectively supports the extended flexible display, enhances usability, and allows for component arrangement in limited spaces by covering open portions and preventing sagging, thus improving the terminal's structural integrity and user experience.
Implementation Method 1
a spring having an inner end portion fixed to the central bracket and an outer end portion fixed to the other side of the first frame or the second frame, wherein the spring is spirally wound in the first state and unwound in the second state
