Solution Overview
Problem
Current shearing tools for strut channel are limited to specific applications, require additional equipment, are heavy and difficult to move, and often need a generator for power, leading to inefficiencies and increased costs.
Innovation Solution
A shear tool system driven by a power assembly with pivotally movable lever arms and dies, adaptable for use with existing power tools like press tools, allowing for portable and versatile shearing operations without the need for dedicated equipment or generators.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If dedicated shearing tools are used for strut channel, then shearing performance is improved, but application versatility deteriorates
Solution Approach 1:
The tool head is designed with a universal interface that can be attached to various power tools including impact wrenches, drill presses, and handheld presses. The tool head includes a frame with a distal end wall and interior region that can accommodate different die configurations, enabling both shearing operations and other applications such as press connections on plumbing lines, making a single tool serve multiple functions
2Force
If high tonnage shearing equipment is used, then shearing capability is improved, but portability deteriorates
Solution Approach 1:
The shearing system is divided into separate components: a portable tool head that can be detached and attached to different power sources. The tool head includes a frame, lever arms, and dies as separate assembleable parts. This segmentation allows the high-tonnage shearing capability to be concentrated in the tool head while the power source can be selected based on portability requirements, such as battery-powered tools
3Use of energy by moving object
If corded shearing tools are used, then power availability is improved, but mobility deteriorates
Solution Approach 1:
The tool head is designed with a universal interface that accepts multiple power source types including battery-powered impact wrenches, drill presses, and handheld presses. This universality allows users to select battery-powered options for mobile applications where power outlets are unavailable, eliminating the need for generators in new construction applications
4Reliability
If multiple dedicated tools are used for different operations, then operation specialization is improved, but equipment complexity deteriorates
Solution Approach 1:
The tool head is designed as a multi-functional device that can perform shearing operations and other applications such as press connections on plumbing lines. The frame includes an interior region that can accommodate different die configurations, and the lever arm mechanism can be adapted for various operations, reducing the need for multiple dedicated tools
Solution Approach 2:
The tool head incorporates pivotally movable lever arms that can be adjusted and reconfigured for different operations. The lever arms are affixed to the frame and can be positioned to contact actuation members in different configurations, allowing the same basic tool structure to adapt to various operational requirements
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The shear tool system provides efficient, portable, and cost-effective shearing capabilities, reducing user effort and equipment costs while enabling use with common power tools, addressing limitations of existing shearing technologies.
Implementation Method 1
a pair of pivotally movable lever arms affixed to the frame, each lever arm defining a proximal region for contacting an actuation member of the power assembly and a distal end directed to the interior region
Implementation Method 2
The shear tool also comprises a pair of pivotally movable lever arms affixed to the frame

AI summary
Shear tools are described that are driven by a power assembly. In one version, the shear tools include a pivotally movable pair of lever arms. Upon activation of the power tool, the lever arms of the shear tool are pivotally displaced and urge a die along a shearing plane relative to another stationary die retained by the shear tool. In another version, the shear tools include a carriage and link assembly. Upon engagement and activation with a power assembly or power tool, a movable die is urged past a stationary die. Also described are systems and related methods utilizing the shear tools which enable convenient shearing or severing of workpieces such as strut channel.
