Pipe Cutter Handle Grips for Stuck Solvent Can Lids
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pipe cutting tools struggle with efficiently removing twist-off lids from adhesive containers due to adhesive flow or overtightening, requiring excessive manual force or additional tools, causing user discomfort.
Innovation Solution
A gripping system is integrated with the handles of a pipe cutting tool to enhance friction and leverage for twisting off twist-off lids, utilizing elongate gripping bodies with teeth or rubber surfaces to facilitate lid removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a user attempts to remove the lid with their hands, then no additional tools are needed, but the user's hands become sore or cramped due to excessive force required
Solution Approach 1:
The pipe cutter tool serves as an intermediary device between the user and the lid. The user operates the pipe cutter handles to generate twisting force, which is transmitted through the tool to the lid, eliminating the need to apply excessive force directly with the hands.
Solution Approach 2:
The pipe cutter tool is designed to perform multiple functions: cutting pipes and removing lids. By integrating the lid removal capability into the existing tool, the patent eliminates the need for separate tools while providing an effective solution for lid removal.
2Force
If a user employs pliers or other tools to remove the lid, then enhanced leverage can be applied, but additional tools are required which may not be accessible or tedious to use
Solution Approach 1:
The pipe cutter tool is designed to perform multiple functions: cutting pipes and removing lids. By integrating the lid removal capability into the existing tool, the patent eliminates the need for separate tools while providing an effective solution for lid removal.
Solution Approach 2:
The pipe cutter tool serves itself by incorporating the lid removal function within its own structure. The handles and blade assembly are configured to naturally accommodate lid removal operations, making the tool self-sufficient without requiring external assistance.
3Productivity
If adhesive is dispensed from the container, then the adhesive can be applied, but adhesive may flow to the junction between the lid and main body making lid removal difficult
Solution Approach 1:
The patent converts the harmful effect of adhesive flow into a beneficial locking mechanism. The adhesive that would otherwise cause difficulty in lid removal is instead utilized to create a positive lock between the lid and container body, making the lid harder to remove and thus securing the adhesive in place.
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
Enables easier and more comfortable lid removal without additional tools, allowing greater force application and reducing user discomfort.
Implementation Method 1
The first gripping body includes a first gripping surface adapted to enhance friction against the lid when the first gripping surface is urged against the lid

AI summary
A gripping system is for use with a pipe cutting tool having a pair of handles and a blade. The gripping system includes an elongate first gripping body configured to be selectively engageable to a first handle to extend along a portion of the first handle. The first gripping body includes a first gripping surface adapted to enhance friction against a lid when the first gripping surface is urged against the lid. An elongate second gripping body is configured to be selectively engageable to a second handle to extend along a portion of the second handle when engaged therewith. The second gripping body includes a second gripping surface adapted to enhance friction against the lid when the second gripping surface is urged against the lid. The gripping bodies are engageable with the handles such that the gripping surfaces are positionable to engage with separate portions of the lid.
