Mobile Terminal Sliding Frame Mechanism for Impact Dispersion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The durability of flexible displays in mobile terminals is compromised when bent, as the bending point is often limited to a specific position, leading to potential damage and reduced durability.
Innovation Solution
A mobile terminal design incorporating a driving unit with a motor, screw shaft, nut fastener, and hook clip system that allows the first frame to slide relative to the second frame, dispersing external impacts and preventing exposure of the driving unit, thereby enhancing durability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the flexible display is bent at a specific position, then the display can be folded or extended, but the durability of the display is compromised due to concentrated stress at the bending point
Solution Approach 1:
The patent divides the mobile terminal into multiple separable frames (first frame and second frame) that can slide relative to each other. This segmentation allows the display to be divided into multiple segments that can be independently positioned, distributing the bending stress across multiple points rather than concentrating it at a single location, thereby improving durability while maintaining folding capability.
Solution Approach 2:
The patent introduces a driving unit with a motor and screw shaft that enables dynamic adjustment of the distance between the first frame and second frame. This dynamic mechanism allows the display to transition between different configurations (folded and extended states) while maintaining structural integrity through controlled movement, preventing damage at specific bending points.
2Ease of operation
If the driving unit is exposed during frame sliding, then the mechanism can operate freely, but contaminants can enter and damage the internal components
Solution Approach 1:
The patent designs the driving unit with a nested structure where the motor, screw shaft, and nut fastener are housed within the second frame. The hook clip mechanism allows the first frame to slide relative to the second frame while the driving unit remains protected within the second frame's structure. This nesting approach maintains operational freedom for the driving unit while preventing contaminant exposure to internal components.
3Stability of the object's composition
If the first frame and second frame are fixed together, then the structure is stable, but the display size cannot be varied
Solution Approach 1:
The patent replaces fixed connection with a dynamic sliding mechanism between the first frame and second frame. The driving unit with motor and screw shaft enables controlled movement along the longitudinal axis, allowing the display size to be adjusted while maintaining structural stability through the guided sliding motion. The hook clip and connection protrusion provide stable engagement at different positions during the sliding process.
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 system effectively controls slide movements and disperses external forces, improving the durability of the flexible display by preventing the driving unit from being exposed and minimizing damage from impacts.
Implementation Method 1
a screw shaft that rotates by receiving the driving force of the motor, a nut fastener including a threaded hole, wherein the screw shaft passes through the threaded hole, wherein the nut fastener moves in the first direction or the second direction when the screw shaft rotates
Implementation Method 2
a driving unit that provides a driving force such that the first frame slides in a first direction or in a second direction opposite to the first direction with respect to the second frame, wherein the driving unit includes a motor fixed to the second frame

AI summary
A mobile terminal comprises: a first frame; a second frame; and a driving unit providing a driving force to the first frame to slide in a first direction with respect to the second frame or in a second direction that is opposite to the first direction, wherein the driving unit comprises: a screw shaft which rotates by receiving a driving force of a motor; a nut fastener which is moved in the first direction or the second direction when the screw rotates; and a hook clip which is fastened to a connection protrusion protruding from the nut fastener and is positioned in the first frame, wherein the hook clip is detachable from the connection protrusion. Accordingly, when an external force is applied, the connection protrusion is detached from the hook clip to disperse impact applied to the driving unit, thereby improving the durability of the driving unit.
