Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing shearing tools for disassembling pipe fittings are limited to a single pipe diameter, requiring multiple tools for different sizes, causing inconvenience and reducing efficiency.

Innovation Solution

A cutting plier with adjustable gap between cutting parts, allowing adaptation to different pipe diameters through an adjusting member, ensuring minimal damage to fittings during cutting.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If existing shearing tools are used with zero gap between cutting parts, then cutting function is achieved, but pipe fittings are damaged

Engineering Contradiction:

Improvecutting functionVSAvoiddamage to pipe fittings

Core Design Contradiction:

Ease of manufactureVSObject-affected harmful factors

Solution Approach 1:

The patent changes the critical parameter of gap distance between cutting parts from zero to a non-zero value. This parameter modification allows the cutting edge to contact and cut the pipe while maintaining sufficient distance to avoid damaging the pipe fitting, thus resolving the contradiction between achieving cutting function and preventing damage to fittings

Inventive Principle:

Principle #35Parameter changes

2Ease of manufacture

If fixed gap cutting pliers are used, then cutting function is achieved, but adaptability to different pipe sizes is lost

Engineering Contradiction:

Improvecutting functionVSAvoidadaptability to different pipe diameters

Core Design Contradiction:

Ease of manufactureVSAdaptability or versatility

Solution Approach 1:

The patent introduces dynamic adjustability to the cutting pliers through an adjusting member that can modify the gap distance between cutting parts. This dynamic feature enables the tool to adapt to different pipe diameters while maintaining the non-zero gap requirement, thus resolving the contradiction between fixed cutting function and adaptability to various pipe sizes

Inventive Principle:

Principle #15Dynamics

3Adaptability or versatility

If multiple shearing tools are used for different pipe sizes, then adaptability is achieved, but device complexity and working efficiency are reduced

Engineering Contradiction:

Improveadaptability to different pipe sizesVSAvoidnumber of tools required

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent creates a universal cutting plier that can handle multiple pipe sizes through the adjusting member mechanism. This single tool performs the function of multiple specialized tools by allowing users to adjust the gap distance according to different pipe diameters, thus resolving the contradiction between adaptability and device complexity

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

A cutting plier and a cutting plier head are provided in this disclosure. The cutting plier includes a cutting plier body, a first cutting part, a second cutting part, an adjusting member and a hinge member. The cutting plier body includes a left handle and a right handle which are hinged with each other. The second cutting part has a shortest gap from the first cutting part and cooperates with the first cutting part to realize a cutting function. The adjusting member is configured for adjusting an amplitude of the shortest gap. One end of the first cutting part is connected with the right handle through a hinge member, and one end of the second cutting part is connected with the left handle through a hinge member.
