Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Conventional folding devices with hinges are inconvenient to use as they require manual opening and lack the ability to extend additional displays or expansion devices when opened, limiting functionality and usability.

Innovation Solution

A transversely movable hinge with a main bracket and moving assembly, comprising a rotating unit, driving unit, and driven unit, which synchronously rotates and moves to extend an expansion device when the folding device is opened, enhancing usability by allowing the expansion device to extend for convenient use.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a conventional hinge is used to connect base and cover, then the folding device can be opened and closed, but the expansion device cannot be automatically extended when opened

Engineering Contradiction:

Improveautomatic extension of expansion deviceVSAvoidhinge structure complexity

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The patent combines the hinge structure with the expansion device extension mechanism into a single integrated moving assembly. The rotating unit, driving unit, and driven unit are merged into one cohesive structure that simultaneously provides both the opening/closing function and the automatic expansion function, eliminating the need for separate mechanisms

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The moving assembly serves multiple functions: it allows the cover to rotate relative to the base for opening/closing, and simultaneously drives the expansion device to extend automatically. The driving unit and driven unit work together to provide both rotational motion and transverse movement, making the hinge structure multi-functional

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If the hinge only allows rotation for opening/closing, then the structure remains simple, but additional displays or expansion devices cannot be extended

Engineering Contradiction:

Improvefunctionality of folding deviceVSAvoidhinge structure complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The hinge structure transitions from a static rotational joint to a dynamic moving assembly that can perform both rotation and transverse movement. The driving unit and driven unit enable the structure to adapt its motion mode based on the operational state, providing enhanced versatility for different device configurations

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The expansion device is nested within the moving assembly structure, allowing it to be compact when retracted and automatically extend when needed. The driving unit and driven unit are integrated within the moving assembly, creating a nested configuration that maximizes space efficiency while providing extended functionality

Inventive Principle:

Principle #7Nested doll (Nesting)

AI summary

A transversely movable hinge is mounted between a base and a cover of a folding device and has a moving assembly. The moving assembly is connected to an expansion device via a linking rod. Therefore, when the folding device is opened, the expansion device is driven to extend and is convenient for users. When the folding device is closed, the expansion device is driven to retract for saving space.
