Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Conventional plying tools with two adjustable plying members fail to achieve a sufficiently small gap between them when positioned closely, limiting their versatility and effectiveness.

Innovation Solution

A double-hinge device with first and second hinges that are releasably fixed relative to each other, allowing the plying members to be moved into various arrangements, including a configuration where the first plying member is connected to the second joining portion and the second plying member to the first joining portion, achieving a smaller gap than conventional tools.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Length of moving object

If the two plying members are placed very near to each other, then the space between them is reduced, but a sufficiently small gap cannot be achieved

Engineering Contradiction:

Improvegap between plying membersVSAvoidability to create various sized spaces

Core Design Contradiction:

Length of moving objectVSAdaptability or versatility

Solution Approach 1:

The plying members are designed with movable connections allowing dynamic reconfiguration. The first and second plying members can be moved between different arrangements (first arrangement with larger gap, second arrangement with smaller gap), enabling the tool to adapt to different working conditions and achieve both small gaps and various sized spaces as needed.

Inventive Principle:

Principle #15Dynamics

2Adaptability or versatility

If the plying members are fixed in a specific arrangement, then the structure is simple, but the tool cannot achieve multiple gap configurations

Engineering Contradiction:

Improvereconfigurability of plying membersVSAvoidmechanism for moving plying members

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The plying tool is divided into separable components (first plying member, second plying member, main body) that can be independently positioned and connected. This segmentation allows the members to be moved between different arrangements while maintaining a relatively simple overall structure, as each component remains fundamentally unchanged.

Inventive Principle:

Principle #1Segmentation

3Length of moving object

If conventional plying tool design is used, then manufacturing is straightforward, but the minimum gap is not sufficiently small

Engineering Contradiction:

Improveminimum achievable gapVSAvoidconstruction complexity

Core Design Contradiction:

Length of moving objectVSEase of manufacture

Solution Approach 1:

The first and second plying members are designed with asymmetric connection features (first joining portion, second joining portion) that enable different connection configurations. This asymmetric design allows the members to be connected in different arrangements to achieve varying gap sizes, including a sufficiently small minimum gap, while maintaining manufacturability through standardized connection interfaces.

Inventive Principle:

Principle #4Asymmetry

AI summary

A plying tool includes a main body including a first joining portion and a second joining portion and a plying member set including a first and second plying member movably and releasably connected with the main body. The first and second plying members are movable relative to each other and adapted to connect with the main body in a first arrangement with the first plying member connected with the first joining portion and the second plying member connected with the second joining portion respectively, and a second arrangement with the first plying member connected with the second joining portion and the second plying member connected with the first joining portion respectively.
