Cable Tie Tool Integrating Cutting With Tightening Handle
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cable tie tools have a complex structure requiring users to manipulate a third handle to control the cutting element, making them inconvenient to use.
Innovation Solution
A cable tie tool with a first and second operating unit, a pivoting shaft, a torsion spring, a cutting assembly, and an extension spring, where the second operating unit has guiding holes and a cutting assembly with an activating element and cutting element, allowing the cable tie to be tightened and cut without needing a third handle for cutting control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a conventional cable tie tool uses a third handle to control the cutting element, then the cutting function can be achieved, but the structure becomes complicated and operation becomes inconvenient
Solution Approach 1:
The patent combines the cutting element control with the existing second handle by integrating a pivoting shaft that moves along guiding holes in the second handle. When the second handle is manipulated, the pivoting shaft automatically triggers the cutting element to cut the cable tie, merging two functions into one handle operation and eliminating the need for a separate third handle.
Solution Approach 2:
The cutting mechanism is designed to activate automatically through the motion of the second handle itself. The pivoting shaft, guided by holes in the second handle, converts the handle's movement into cutting action without requiring additional user input or a separate control mechanism, making the system self-sufficient.
2Productivity
If the cable tie tool integrates tightening and cutting functions, then productivity improves, but the device complexity increases
Solution Approach 1:
The patent merges the tightening and cutting functions into a single integrated tool where both operations are performed using the same two handles. The first handle provides stopping/clamping function while the second handle provides both pushing/tightening and cutting activation functions, allowing sequential completion of both tasks without switching tools.
Solution Approach 2:
The second handle is designed with multi-functionality, serving both as the pushing element for tightening the cable tie and as the trigger for the cutting element. This universal design allows one component to perform multiple functions, reducing the need for separate specialized components.
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 tool simplifies the structure and operation, allowing direct manipulation of the first and second operating units to cut the cable tie, making it more convenient and user-friendly compared to conventional tools.
Implementation Method 1
a torsion spring, The torsion spring abuts against and pushes the first and the second operating units
Implementation Method 2
The extension spring is connected between the activating element and the second operating unit. The extension spring is stretched such that the activating element blocks the pivoting shaft from moving along the guiding holes

AI summary
A cable tie tool has a first operating unit (10), a second operating unit (20) having two guiding holes (23) aligned to each other, a pivoting shaft (30), a torsion spring (40) abutting against and pushing the first and the second operating units (10, 20), a cutting assembly (50) having an activating element (51) pivotally connected to the second operating unit (20) and a cutting element (52) movably mounted in the second operating unit (20) and driven by the activating element (51), and an extension spring (60) connected between the activating element (51) and the second operating unit (20). The pivoting shaft (30) is pivotally connected the two operating units (10, 20), and movable along the guiding holes (23). When the extension spring (60) is stretched, the activating element (51) blocks the pivoting shaft (30) from moving along the guiding holes (23).
