Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile terminal devices with fixed display screens fail to meet diverse user needs for varying screen sizes during different tasks.
Innovation Solution
A support structural member with a movable support frame and power assembly that adjusts the display area by protruding or retracting a second support body, accompanied by a screen body connector, to unfold or fold a flexible screen, allowing adjustable display size.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the display screen size is fixed, then the device structure is simple, but the device cannot meet diverse user needs for varying screen sizes
Solution Approach 1:
The support frame is designed with a movable second support body that can protrude or retract relative to the first support body, enabling dynamic adjustment of the display screen size. The power assembly drives this movement, transforming the static structure into a dynamic one that adapts to different usage scenarios while maintaining reasonable structural complexity through integrated design.
2Area of stationary object
If the flexible screen is unfolded to increase display area, then the display size increases, but the screen becomes more vulnerable to impact forces
Solution Approach 1:
The support frame structure is designed to provide protective support for the flexible screen. When the second support body protrudes, it creates a buffered support structure that reduces the direct impact on the screen. The power assembly and support frame work together to provide beforehand cushioning, reducing the risk of screen damage from impact forces while maintaining an increased display area.
3Adaptability or versatility
If the support frame is made movable to adjust display area, then the adaptability improves, but the device complexity increases
Solution Approach 1:
The power assembly is integrated with the support frame structure, merging the driving mechanism with the support structure. The first support body and second support body are combined into a unified movable support frame system, reducing the number of separate components. This merging approach enables adjustable display area while controlling the increase in device complexity through integrated design.
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
Enables flexible screen devices to adapt to different use scenarios by freely adjusting the display area, enhancing user satisfaction and reducing the risk of screen damage from impact forces.
Implementation Method 1
a first threaded rod rotatably connected to the second support body and threadly connected with the first support body, when the first threaded rod rotates, the first threaded rod and the second support body move synchronously relative to the first support body in the first direction
Implementation Method 2
the power assembly driving the second support body to protrude or retract relative to the first support body, and enabling the screen body connector and the second support body to move simultaneously in the first direction
