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

VSEngineering 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

Engineering Contradiction:
Improvehooking operationVSAvoidtool stability
Core Design Contradiction:
Ease of operationVSStability of the object's composition

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

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

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

Engineering Contradiction:
Improvehooking operationVSAvoidwork transition time
Core Design Contradiction:
Ease of operationVSLoss of time

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

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

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

Engineering Contradiction:
Improvehooking operationVSAvoiddamage to surrounding reinforcing bar
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

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

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

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.
