Folding Terminal Device With Telescopic Joints For Screen Area
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a challenge in increasing the screen area of terminal devices without compromising their portability, as larger screens often result in increased overall device sizes.
Innovation Solution
The terminal device incorporates at least two folding portions, a rotational shaft, and a telescopic device, where the folding portions are connected by the telescopic device, allowing the device to switch between a folded state for reduced size and an extended state for increased screen area, ensuring portability and expanded display.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the screen area of terminal devices is increased, then the display capability is improved, but the overall device size increases and portability deteriorates
Solution Approach 1:
The terminal device is divided into multiple folding portions (first folding portion, second folding portion, etc.) that can be independently folded and extended. Each folding portion contains a housing and display screen, and adjacent folding portions are connected by telescopic devices. This segmentation allows the device to achieve a large screen area when extended while maintaining a compact form when folded, resolving the contradiction between screen size and portability.
Solution Approach 2:
The terminal device employs dynamic structures including telescopic devices and rotational shafts that enable the folding portions to extend and retract. The telescopic devices can extend to increase the distance between folding portions (increasing screen area) and retract to decrease the distance (reducing device size). This dynamic capability allows the device to adapt between large and compact states, resolving the contradiction between screen area and overall size.
2Area of stationary object
If the device is designed to fold and extend, then screen area can be increased without affecting portability, but the device structure becomes more complex
Solution Approach 1:
The telescopic devices serve multiple functions: they connect adjacent folding portions, enable extension and retraction movements, provide structural support, and facilitate the transition between folded and extended states. By making the telescopic devices multi-functional, the patent reduces the need for separate components for each function, thereby managing device complexity while achieving the desired screen area and portability.
