Rebar Tying Tool Push Member Front Arrangement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing rebar tying tools require significant space for the operated unit due to its configuration, limiting the degree of freedom in arrangement and increasing the size of the tool, especially when the push member is disposed on the rear side relative to the fin member.
Innovation Solution
The rebar tying tool configuration is modified with the push member disposed on the front side relative to the fin member, allowing for a reduced space requirement in the front-rear direction, enabling a more compact design and improved arrangement flexibility by positioning the operated unit closer to the rebars.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the push member is disposed on the rear side relative to the fin member, then the operated unit can be arranged with sufficient space, but the tool size increases and degree of freedom in arrangement is reduced
Solution Approach 1:
The patent inverts the conventional arrangement by positioning the push member on the front side relative to the fin member, rather than on the rear side. This inversion allows the operated unit to be positioned closer to the rebars, reducing the overall tool size while maintaining operational effectiveness. The cutting unit is arranged between the push member and the rebars, optimizing the spatial configuration.
2Volume of moving object
If the operated unit is positioned closer to the rebars, then the tool becomes more compact, but the space required for the operated unit's movement is reduced
Solution Approach 1:
The patent utilizes the front-rear dimension effectively by positioning the push member on the front side of the fin member. This dimensional arrangement allows the operated unit to move in a compact space while maintaining sufficient operational range. The cutting unit is positioned between the push member and the rebars, enabling effective cutting motion within a reduced spatial envelope.
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
This configuration reduces the distance between the push member and the rebars, allowing for a smaller cutting unit and a more compact tool design, enhancing the tool's usability and arrangement flexibility.
Implementation Method 1
a screw shaft configured to rotate, a sleeve through which the screw shaft is inserted and configured to move in a front-rear direction and rotate

AI summary
A rebar tying tool may include: a screw shaft configured to rotate; a sleeve through which the screw shaft is inserted, and configured to move in a front-rear direction and rotate; a fin member attached to the sleeve and configured to permit and prohibit rotation of the sleeve; a push member attached to the sleeve and configured to rotate about the sleeve, wherein the push member does not rotate along with the rotation of the sleeve; an operated unit having a longitudinal direction in the front-rear direction and configured to be operated by the push member when the sleeve moves in the front-rear direction; and a grasping unit protruding from a front part of the sleeve, configured to rotate with the sleeve, and configured to grasp the wire. The push member may be disposed on a front side relative to the fin member.
