Modified Basin Wrench With Pivoting Head for Simultaneous Nut Fastening
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing basin wrench designs fail to simultaneously grip, fasten, and loosen water supply locknuts and faucet shank nuts in hard-to-reach areas, requiring multiple steps and tools.
Innovation Solution
A modified basin wrench with a wrench head featuring slits and a through hole that cooperates with the shape of the nuts, combined with an elongated rod assembly and pivoting mechanism, allowing for simultaneous operation of both nuts using a single tool.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a conventional basin wrench is used, then the tool structure remains simple, but it requires multiple steps and tools to fasten or loosen water supply locknut and faucet shank nut
Solution Approach 1:
The patent combines two separate gripping functions into a single wrench head assembly. The wrench head includes both slits for gripping the water supply locknut and grooves for gripping the faucet shank nut, allowing both nuts to be operated simultaneously with one tool, thereby eliminating the need for multiple tools and steps
Solution Approach 2:
The wrench head is designed with multi-functional capabilities to handle different nut types and positions. The combination of slits and grooves in the wrench head enables it to universally grip and operate both the water supply locknut and faucet shank nut, making the tool adaptable to multiple fastening scenarios
2Ease of operation
If a standard basin wrench is used, then the tool design remains simple, but it cannot reach hard to access areas under a sink
Solution Approach 1:
The patent incorporates a pivoting mechanism that allows the wrench head assembly to rotate and articulate. This dynamic feature enables the wrench to maneuver around obstacles and access confined spaces under sinks by adjusting the angle and position of the wrench head, making it adaptable to various spatial constraints
3Ease of operation
If a rigid wrench head is used, then the tool structure remains simple, but it cannot maneuver easily around sink cabinet obstacles
Solution Approach 1:
The wrench head assembly is designed with a pivoting mechanism that provides dynamic movement capability. This allows the assembly to rotate and adjust its position to navigate around obstacles such as pipes and fixtures in the sink cabinet area, significantly improving maneuverability compared to rigid designs

AI summary
A modified basin wrench including an elongated rod assembly, wrench head assembly, handle assembly, and a pivoting assembly is disclosed herein. The wrench head assembly is modified in a way to allow the user to fasten and/or loosen the water supply locknut and faucet shank nut simultaneously. The modified basin wrench further includes a handle assembly that is hingedly attached to the wrench head assembly by a pivot assembly in order to help the user grasp the faucet nut at a comfortable angle in hard to reach places. Furthermore, this can allow the user to fasten and loosen the water supply locknut and/or faucet shank nut without having to lie down. The modified basin wrench also includes a handle assembly that can be used to adjust the grip of the tool and allows the user to operate the wrench with one hand.
