Solution Overview

Problem

Existing disconnecting tools for quick connect fittings are limited to single-sized pipe diameters, making them inconvenient for use with fittings of different sizes and reducing efficiency when disconnecting pipelines with varying diameters.

Innovation Solution

A disconnect tong with variable distance between clamping parts, featuring multiple accommodating grooves of different sizes and shapes, allowing it to be applied to various pipe fittings without needing separate tools, including quick joints with teeth, for easy and quick disconnection.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a single-sized disconnecting tool is used, then the tool structure is simple, but it cannot be applied to pipe fittings with different sizes

Engineering Contradiction:
Improveapplicability to different pipe fitting sizesVSAvoidtool structure complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The disconnecting tool is designed with multiple accommodating grooves of different sizes and shapes on both the first and second clamping parts, enabling a single tool to adapt to various pipe fitting sizes and configurations. This multi-functional design allows the tool to universally apply to different disconnecting scenarios without requiring multiple specialized tools.

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

Solution Approach 2:

The clamping parts are segmented into multiple accommodating grooves with different dimensions, allowing each groove to specifically accommodate different types of pipe fittings. This segmentation enables the tool to handle various sizes while maintaining a unified overall structure.

Inventive Principle:
Principle #1Segmentation

2Productivity

If disconnecting tools for different sizes are used, then each tool is optimized for its specific size, but users need to carry multiple tools which reduces working efficiency

Engineering Contradiction:
Improveworking efficiencyVSAvoidconvenience of use
Core Design Contradiction:
ProductivityVSEase of operation

Solution Approach 1:

By integrating multiple accommodating grooves of different sizes into a single disconnecting tool, the invention eliminates the need for users to carry and switch between multiple size-specific tools. This universal design significantly improves working efficiency and convenience by allowing users to handle all pipe fitting sizes with one tool.

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

3Adaptability or versatility

If the distance between clamping parts is fixed, then the tool structure is simple, but it cannot accommodate fittings at different positions

Engineering Contradiction:
Improveadaptability to different positionsVSAvoidstructure complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The disconnecting tool incorporates a variable distance mechanism between the first and second clamping parts, allowing the distance to be adjusted dynamically based on the position and size of the pipe fittings being disconnected. This dynamic adjustment capability enables the tool to adapt to different fitting positions while maintaining operational simplicity.

Inventive Principle:
Principle #15Dynamics
