Plumbing Wrench With Extendable Arm For Confined Valve Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing manual wrench tools are inadequate for accessing and manipulating plumbing hardware in confined or difficult-to-reach locations, requiring significant physical effort and often necessitating the assistance of multiple persons due to the need for applying large forces and stabilizing the hardware during installation or removal.
Innovation Solution
A specialized wrench tool with a wrench member, an elongate arm member that can extend orthogonally, and a handle member configured to reduce physical strain, allowing for single-person operation by enabling the tool to remain stationary while manipulating plumbing hardware through a rotating shaft within a gap formed by angled appendages.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional wrench tools are used to manipulate plumbing hardware in difficult-to-reach locations, then the hardware can be manipulated, but multiple persons are required and physical strain is significant
Solution Approach 1:
The tool is divided into distinct functional segments: a wrench member for engaging the plumbing hardware, an elongate arm member for reaching into confined spaces, and a handle member for user operation. This segmentation allows each component to perform its specific function efficiently, enabling single-person operation while maintaining the ability to manipulate hardware in difficult-to-reach locations
Solution Approach 2:
The elongate arm member acts as an intermediary between the user's handle and the wrench head, transmitting force and motion over a distance. This intermediary structure allows the user to apply force at the handle while the wrench head engages with plumbing hardware in confined spaces, eliminating the need for multiple persons to directly manipulate the hardware
2Ease of operation
If traditional wrench tools are used to manipulate plumbing hardware, then the hardware can be manipulated, but large amounts of force are required
Solution Approach 1:
The tool extends the operational dimension by using an elongate arm member that reaches into confined spaces while maintaining force application capability. This dimensional extension allows the user to apply force remotely through the arm structure, reducing the physical effort needed at the manipulation point while still delivering sufficient force to the plumbing hardware
3Ease of operation
If the wrench is placed on the valve in difficult-to-reach locations, then the valve can be manipulated, but the user must lie down or kneel causing physical strain
Solution Approach 1:
The elongate arm member serves as an intermediary that extends the user's reach into confined spaces without requiring the user to adopt awkward positions. The arm transmits operational force from the handle to the wrench head, allowing the user to remain in a comfortable, upright position while manipulating valves in difficult-to-reach locations
Solution Approach 2:
The tool adds spatial dimensionality through its extended arm structure, allowing the user to access overhead or confined spaces without changing their body position. This dimensional extension eliminates the need to lie down or kneel, reducing physical strain while maintaining access to difficult-to-reach plumbing hardware
