Binding Machine Hook Layout for Stable Rebar Hanging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tools, such as reinforcing bar binding machines, tend to become unstable and prone to falling when hooked onto reinforcing bars due to improper hook orientation, leading to potential damage and inefficiencies in work processes.
Innovation Solution
The tool design incorporates a first hook attachment unit on the upper surface with the hook opening facing forward and a second hook attachment unit on the side surface with the opening facing downward, allowing for stable hooking without tilting and reducing interference with surrounding objects.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the hook is attached to the side surface of the main body with the opening facing the front, then the tool can be hooked on reinforcing bars, but the tool becomes significantly tilted and unstable, causing it to easily fall from the reinforcing bar
Solution Approach 1:
The patent introduces a second hook attachment unit on the upper surface of the main body, adding a new dimensional option for hook attachment. This allows the hook opening to face upward instead of forward, changing the orientation dimension and enabling stable hooking without tool tilting
2Ease of operation
If the hook is attached to the lower side of the gripping unit, then the tool can be hooked on reinforcing bars, but the worker needs to turn over his wrist which was difficult to execute, preventing quick progression to the next work
Solution Approach 1:
The patent relocates the hook attachment from the lower side of the gripping unit to the upper surface of the main body. This positional change in the vertical dimension allows workers to hook the tool without wrist rotation, enabling quick transition to the next work
3Ease of operation
If the hook is attached to the side surface of the main body, then the tool can be hooked on reinforcing bars, but the tool easily comes into contact with surrounding reinforcing bar or the like, causing damage to the surrounding reinforcing bar and the tool itself
Solution Approach 1:
The patent moves the hook attachment from the side surface to the upper surface of the main body. This vertical repositioning changes the spatial relationship between the tool and surrounding reinforcing bars, preventing contact and damage while maintaining hooking functionality

AI summary
A tool includes: a main body includes an output section provided on a front end portion in a longitudinal direction and accommodating a driving unit for driving the output section therein; a gripping unit provided on a lower surface side of the main body; a first hook attachment unit located on an upper surface side of the main body and to allows a hook opened at one side attached; and a second hook attachment unit located on a side surface side of the main body and allows the hook attached. The hook is attached to the first hook attachment unit so that an opening of the hook faces the front side in the longitudinal direction of the main body. The hook is attached to the second hook attachment unit so that the opening of the hook faces the lower side in an upper-lower direction.
