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

VSEngineering 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

Engineering Contradiction:
Improveadaptability to various usage scenariosVSAvoiddevice structure
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

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

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Reliability

If all contents are provided from one terminal, then the device structure is simple, but security is weak

Engineering Contradiction:
ImprovesecurityVSAvoiddevice structure
Core Design Contradiction:
ReliabilityVSDevice complexity

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

Inventive Principle:
Principle #1Segmentation

3Ease of operation

If a foldable keyboard is added to provide keyboard input environment, then input capability is improved, but device complexity increases

Engineering Contradiction:
Improvekeyboard input capabilityVSAvoiddevice structure
Core Design Contradiction:
Ease of operationVSDevice complexity

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

Inventive Principle:
Principle #5Merging (Combining)

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

Engineering Contradiction:
Improvemounting and separation easeVSAvoidconnection reliability
Core Design Contradiction:
Ease of operationVSReliability

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

Inventive Principle:
Principle #7Nested doll (Nesting)
