Pivoting Interchangeable Hand Tool Torque Arm
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hand tools face challenges when working in tight spaces, such as reduced torque due to pivoting torque arms, weakened torque arms from telescoping designs, and bulkiness of T-handles, with no solution combining pivoting, extending, and interchangeable features effectively.
Innovation Solution
A pivoting and extending interchangeable hand tool device featuring a tool head and torque arm that pivot relative to each other, a secondary torque arm for length extension, and a T-handle for support, allowing for adjustable angles and lengths while maintaining torque strength, with interchangeable tool heads and a resilient, waterproof construction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a pivoting tool head is added to the torque arm to work in tight spaces, then the tool can be angled into small areas, but the effective length of the torque arm is reduced and torque application is weakened
Solution Approach 1:
The device is divided into separate modular components: a tool head assembly that can pivot independently from the torque arm. This segmentation allows the torque arm to maintain its full length for maximum torque while the tool head can be angled into tight spaces through the pivoting connection.
2Length of moving object
If a telescoping torque arm is implemented to reach tight areas, then the arm can be lengthened or shortened, but the torque arm becomes weaker due to circular hollow construction
Solution Approach 1:
The telescoping torque arm uses a nested construction where one tube is inserted within another, allowing the arm to extend and retract while maintaining structural strength. The concentric arrangement provides rigidity without requiring a hollow circular cross-section, solving the weakness problem of telescoping designs.
3Strength
If a T-handle is added to offset torque loss, then torque can be applied perpendicularly, but the device becomes bulkier
Solution Approach 1:
The tool head assembly serves multiple functions: it can be positioned at various angles through pivoting to access tight spaces, and it incorporates the torque application interface. This multi-functionality eliminates the need for a separate T-handle, maintaining a compact design while providing effective torque application.
4Adaptability or versatility
If the torque arm is angled relative to the tool head to access small areas, then work can be performed in tight spaces, but the effective torque arm length is reduced
Solution Approach 1:
The connection between the torque arm and tool head is made dynamic through a pivoting mechanism, allowing the tool head to be angled into tight spaces while the torque arm maintains its full length. The pivot enables independent movement of the tool head from the torque arm, preserving the effective torque length.

AI summary
The pivoting and extending interchangeable hand tool device disclosed herein may comprise a tool head and a torque arm that pivot relative to one another, a secondary torque arm for extending length and increasing appliable torque, and a “T”-handle for additional support. The pivoting and extending interchangeable hand tool device may further comprise a plurality of tool heads that may be interchanged within the secondary torque arm, and may be provided commercially in a multiple-tool set. The device is designed to overcome the shortcomings in the prior art, which specifically include the ability to work in tight spaces while reducing the loss of torque when pivoting a torque arm, the loss of strength inherent in an extendable torque arm, and the bulkiness of a “T”-handle.
