Solution Overview

Problem

In the construction field, workers face difficulties in disassembling and assembling pipes due to stuck connections caused by adhesive and corrosion, leading to strain and slippage accidents when using wrenches, often requiring two workers and increased costs.

Innovation Solution

A wrench securing plate system with a base plate and handle holding loops made of ferrous material, allowing a user to securely hold a wrench, freeing up hands for manipulating workpieces without needing to hold the wrench, and optionally including a receiver hitch for portability.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Force

If a worker uses a cheater-pipe to increase leverage for removing stuck pipes, then the leverage is increased, but the likelihood of accidents increases and a second worker is needed

Engineering Contradiction:
ImproveleverageVSAvoidsafety
Core Design Contradiction:
ForceVSReliability

Solution Approach 1:

The patent introduces a stationary base plate with handle-holding loops as an intermediary device. The loops securely hold the wrench handle, acting as a stable intermediary that provides leverage without requiring a second worker or cheater-pipe, thereby eliminating the safety risks associated with those methods

Inventive Principle:
Principle #24Intermediary (Mediator)

2Adaptability or versatility

If a worker uses two pipe-wrenches in opposing directions to remove stuck fittings, then the disassembly capability is improved, but the complexity of operation increases and requires two workers

Engineering Contradiction:
Improvedisassembly capabilityVSAvoidoperation complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The base plate with handle-holding loops enables the wrench to be self-supported and stationary during operation. The loops are designed to securely hold the wrench handle in place, allowing the wrench to effectively apply force to stuck fittings without requiring a second worker to stabilize or operate another wrench, thus simplifying the operation to a single-worker task

Inventive Principle:
Principle #25Self-service

3Ease of operation

If a worker manually holds the wrench to manipulate pipes, then the control over the wrench is maintained, but the worker cannot simultaneously manipulate workpieces with both hands

Engineering Contradiction:
Improvewrench controlVSAvoidworkpiece manipulation efficiency
Core Design Contradiction:
Ease of operationVSProductivity

Solution Approach 1:

The base plate with handle-holding loops serves as a stationary intermediary that secures the wrench handle in place. This allows the worker to apply force and control the wrench through the loops without needing to manually hold it, thereby freeing both hands to manipulate workpieces and significantly improving productivity

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

A specialty tool for holding a pipe wrench stable when assembling or disassembling piping systems. While working in the field, plumbers normally have to balance one pipe wrench on its spine, holding it either between their knees or under one foot, while using another wrench for assembling/disassembling pipes, valves and fittings. Anyone who's attempted to perform this kind of task has experienced the aggravation, frustration and time loss associated with holding and balancing wrenches in this manner which this device serves to solve.
