Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current flexible display screens in electronic devices cannot adjust screen size freely according to user needs, limiting adaptability in various situations.
Innovation Solution
A terminal with an adjustable screen size mechanism using stepping motors, a rotating shaft, and a chain plate to drive relative movement between two bodies, allowing the flexible display screen to expand or contract based on user control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the flexible display screen is folded along a pre-designed folding line to adjust screen size, then the screen size can be changed, but the screen size cannot be adjusted freely according to users' needs
Solution Approach 1:
The patent applies the dynamics principle by replacing the fixed folding line mechanism with a dynamic chain plate system that can extend and contract along the longitudinal direction. The chain plate, driven by rotating shafts, enables the flexible display screen to adjust its length continuously rather than along a predetermined path, achieving free screen size adjustment according to user needs.
2Area of stationary object
If the flexible display screen is expanded to provide a large screen, then the screen area increases, but the device thickness increases
Solution Approach 1:
The patent applies the dimensionality change principle by shifting the expansion mechanism from the thickness direction to the longitudinal direction. Instead of expanding the screen by increasing device thickness, the chain plate system extends the screen area along the length of the device, maintaining a relatively constant thickness while achieving variable screen areas.
3Device complexity
If a fixed folding line mechanism is used to adjust screen size, then the structure is simple, but the screen size is relatively fixed and cannot be adjusted freely
Solution Approach 1:
The patent replaces the static folding line with a dynamic chain plate mechanism driven by rotating shafts. This dynamic system allows the screen to be divided into multiple adjustable regions that can extend and contract along the longitudinal direction, providing continuous screen size variability while maintaining a relatively simple overall structure.
