Foldable Multimedia Terminal With Keyboard Input And Dual Screen
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional multimedia terminals lack the ability to provide a keyboard input environment and dual screen functionality while ensuring security and easy mounting/separation, with limited flexibility in adapting to various usage scenarios.
Innovation Solution
A foldable multimedia terminal design that includes a foldable keyboard with a first terminal unit and a second terminal unit, where the second unit is integrated on the rear surface, allowing for dual screen operation and automatic switching between units based on folding detection, along with a terminal holder for easy mounting and protection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single terminal is used for all functions, then the device structure is simple, but security is weak and adaptability to various usage scenarios is limited
Solution Approach 1:
The patent implements multi-functionality by integrating multiple terminal units (first terminal unit and second terminal unit) into a single foldable multimedia terminal. Each terminal unit can independently function as a complete terminal device, enabling the system to adapt to various usage scenarios such as dual-screen mode, keyboard input mode, and independent device mode, thereby achieving universal applicability without requiring entirely separate devices
2Reliability
If all contents are provided from one terminal, then the device structure is simple, but security is weak
Solution Approach 1:
The patent segments the terminal functions by dividing contents into open type contents and security type contents, and assigning them to different terminal units. The first terminal unit handles open type contents while the second terminal unit handles security type contents, creating functional segmentation that enhances security without requiring completely separate physical devices
3Ease of operation
If a foldable keyboard is added to provide keyboard input environment, then input capability is improved, but device complexity increases
Solution Approach 1:
The patent merges the keyboard function with the second terminal unit by integrating the foldable keyboard structure into the second terminal unit housing. This combination allows the keyboard to serve dual purposes: as a physical input device when folded, and as a structural component of the second terminal unit when unfolded, thereby improving input capability while minimizing additional complexity
4Ease of operation
If terminal units are made separable for easy mounting and separation, then ease of operation is improved, but connection reliability may be reduced
Solution Approach 1:
The patent implements a nested structure where the second terminal unit is accommodated within the foldable keyboard structure. When the keyboard is folded, the second terminal unit nests into a designated space within the keyboard housing, providing secure mechanical retention while allowing easy deployment and retraction, thus achieving both ease of operation and connection reliability

AI summary
A foldable multimedia terminal capable of providing a keyboard input condition or a dual screen is disclosed, comprising: a foldable keyboard having one-side keyboard and the other-side keyboard foldably connected to the one-side keyboard such that a user performs an input; a first terminal unit which has a touch display so as to allow an input to be carried out by means of the foldable keyboard or by means of touch, while being linked with the foldable keyboard, and which performs at least one from among calling, internet communication, and multimedia content functions; a second terminal unit which is provided so as to be integrated with or separated from the rear surface of the one-side keyboard and/or the other-side keyboard constituting the foldable keyboard, and which provides the dual screen together with the first terminal unit or takes over the function of the first terminal unit while being linked with the first terminal unit; and a terminal holder which is provided on the foldable keyboard so as to accommodate the first terminal unit or which accommodates the first terminal unit and/or the second terminal unit when the second terminal unit is separably provided on the foldable keyboard.
