Slip Coupling Driving Tool for Damage-Free Pipe Installation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional coupling tools for slip couplings in pipe repairs often require hammering, which can damage the coupling or pipes due to direct contact, and the use of scrap wood leads to frequent replacement and potential damage.
Innovation Solution
A slip coupling tool featuring a semi-annular collar with a striking plate and handle that allows precise alignment and impact to drive the slip coupling into place without direct contact with the hammer, reducing the risk of damage and eliminating the need for scrap wood.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a hammer is used directly to drive the slip coupling into place, then the installation process is simple, but the coupling or pipes may be damaged
Solution Approach 1:
The patent introduces a specialized driving tool as an intermediary between the hammer and the slip coupling. This tool includes a striking surface that receives hammer blows and a tapered driving end that contacts the coupling, distributing the impact force and preventing direct hammer contact with the coupling or pipes, thus eliminating damage while maintaining installation simplicity
Solution Approach 2:
The driving tool incorporates a semi-annular collar with a circular inner surface that engages the pipe exterior and a striking plate with an impact surface spaced from the collar. This structure cushions and distributes the impact force before it reaches the coupling, preventing damage while enabling effective installation
2Object-affected harmful factors
If scrap wood is used to tap the coupling into place, then direct hammer contact with the coupling is avoided, but the wood chips and splits requiring frequent replacement
Solution Approach 1:
The patent replaces the disposable scrap wood with a durable, reusable driving tool made of sturdy material. The tool is designed to withstand repeated hammer blows without chipping or splitting, eliminating the need for frequent replacement while maintaining the protective function of preventing coupling damage
Solution Approach 2:
The driving tool combines multiple components (semi-annular collar, striking plate, handle) made from durable materials that can withstand impact forces. This composite structure provides both protection for the coupling and durability for the tool itself, eliminating the need for frequent replacements
3Productivity
If the hammer contacts the pipe or coupling during installation, then the coupling can be driven into place, but damage occurs requiring removal and further repair
Solution Approach 1:
The driving tool serves as an intermediary that guides the hammer blows precisely onto the coupling through its tapered driving end, while the semi-annular collar and striking plate distribute and cushion the impact forces. This ensures the coupling is driven into place without hammer contact damaging the pipe or coupling, achieving both efficiency and reliability

AI summary
A slip coupling tool having an interior surface sized for receiving a pipe. The coupling tool includes a semi-annular collar sized to engage an exterior surface of the pipe. The collar extends to a rearward end face sized and shaped for aligning with an end of the slip coupling when the collar receives the pipe and the inner surface of the collar engages an exterior surface of the pipe. The slip coupling tool includes a striking plate extending outward from the collar. The striking plate has an impact surface spaced from the collar for impacting the coupling tool to drive the slip coupling into position along the pipe. The slip coupling tool includes a handle extending outward from the collar for manipulating the tool into position while impacting the impact surface of the striking plate to drive the slip coupling into position along the pipe.
