Multi-Functional Tool for Flexible Pipe Compression and Cutting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing tools for working with flexible plastic pipes require multiple separate tools for different sizes and types of connections, compression, cutting, and measurement, leading to inefficiencies and bulkiness, especially for larger pipe sizes where increased mechanical advantage and force are needed.
Innovation Solution
A multi-functional hand tool with pivotally connected jaws and collars that can compress, cut, and measure flexible pipes of various sizes using a single hand, featuring adjustable mechanisms for varying hand force and accommodating different types of compression rings and sleeves, including a built-in cutting blade and 'go no-go' gauge.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple separate tools are used for different pipe sizes and operations, then each tool can be optimized for its specific function, but the overall system becomes bulky and requires multiple tools to be carried and managed
Solution Approach 1:
The patent combines multiple previously separate tools (compression tool, pipe cutter, gauges) into a single integrated multi-functional tool. The compression jaws, cutting blade, and measurement gauges are all integrated into one device that can perform compression, cutting, and measurement operations on flexible plastic pipes of various sizes using a single tool body.
Solution Approach 2:
The tool is designed with universal applicability to handle multiple pipe sizes (3/8 inch, 1/2 inch, 5/8 inch, 3/4 inch, and 1 inch) and multiple operation types (compression, cutting, measurement) within a single device. The adjustable jaw mechanisms and interchangeable collars enable the tool to adapt to different pipe diameters and connection requirements.
2Adaptability or versatility
If larger pipe sizes are accommodated, then the tool can handle bigger pipes, but increased mechanical advantage and force are needed making the tool bulkier
Solution Approach 1:
The tool employs dynamic, adjustable jaw mechanisms that can be reconfigured for different pipe sizes. The collars and jaw members can be adjusted or replaced to match the specific pipe diameter being worked on, allowing the tool to maintain an compact form factor while accommodating a wide range of pipe sizes from 3/8 inch to 1 inch and beyond.
3Productivity
If separate tools are used for compression, cutting, and measurement, then each operation can be performed with specialized equipment, but the installation process becomes slower and less efficient
Solution Approach 1:
The patent integrates compression jaws, a cutting blade, and measurement gauges into a single tool body, allowing the installer to perform compression, cutting, and measurement operations sequentially without putting down or switching between multiple separate tools. This integration streamlines the installation process and improves productivity.
4Force
If traditional two-handed compression tools are used, then sufficient force can be applied to compress rings and sleeves, but the tool requires two hands and cannot be used in tight spaces
Solution Approach 1:
The compression mechanism is segmented into two independent jaw members (first jaw member and second jaw member) that can be operated separately. Each jaw member has its own handle that can be actuated independently, allowing the user to apply compression force with one hand while maintaining control over the compression process.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This tool consolidates multiple functions into one device, reducing the need for multiple tools, providing compact mechanical advantage for compressing and cutting, and allowing single-handed operation, thus improving efficiency and access in tight spaces while accommodating wear and size variations.
Implementation Method 1
The first and second jaws are configured to move between an open position and a closed position to thereby connect flexible pipe by compressing flexible pipe connecting rings or sleeves
Implementation Method 2
The cutting blade is configured to cut flexible pipe
Implementation Method 3
The gauge may be used to measure a diameter of the compressed ring or sleeve to ensure that the ring or sleeve has been compressed to within +/â0.008 inch of a target compressed diameter

AI summary
A multifunctional tool includes first and second handle members, first and second jaw members operatively connected to the first and second handle members and movable between a first open position and a second closed position, and first and second removable collar attachment members configured to be removably installed in the first and second jaw members, respectively, to provide different sizes of compressing and/or cutting diameters when the first and second jaw members are in the second closed position.
