Solution Overview

Problem

Existing reinforcing bar binding machines face inefficiencies in aligning and engaging wires, leading to increased load on clamping plates and decreased operation efficiency due to the parallel alignment of wires, which hinders the binding process.

Innovation Solution

A binding machine with a wire feeding unit, a binding unit featuring openable/closable engaging members, and a control unit that regulates the alignment of wires to intersect with the opening/closing direction of the engaging members, allowing for secure engagement and reduced load on the clamping plates by aligning wires in a radial direction suitable for engagement.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If two wires are aligned in parallel in the opening/closing direction of the clamping plates, then the clamping plates cannot be closed to a predetermined position, but this increases the load on the clamping plates and deteriorates operation efficiency

Engineering Contradiction:

Improvegripping reliabilityVSAvoidoperation efficiency

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The patent inverts the conventional wire alignment approach by aligning wires in the radial direction perpendicular to the opening/closing direction of the engaging members, rather than parallel to it. This inversion allows the engaging members to close properly while maintaining reliable wire engagement, resolving the contradiction between gripping reliability and operation efficiency

Inventive Principle:

Principle #13The other way round (Inversion)

Solution Approach 2:

The patent changes the dimensional orientation of wire alignment from being parallel to the opening/closing direction (one dimension) to being perpendicular in the radial direction (another dimension). This dimensional change enables the clamping plates to close to the predetermined position while still securely engaging the wires, eliminating the load increase and efficiency deterioration

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

2Reliability

If two wires are aligned in parallel in the contact/separation direction of the engaging members, then the wires are engaged with an interval formed, but this increases the load on the engaging members

Engineering Contradiction:

Improveengagement securityVSAvoidload on engaging members

Core Design Contradiction:

ReliabilityVSForce

Solution Approach 1:

The patent inverts the wire alignment orientation by positioning wires perpendicular to the contact/separation direction of the engaging members, rather than parallel to it. This inversion eliminates the formation of intervals between wires during engagement, allowing the engaging members to contact the wires directly and securely while reducing the load applied to the members

Inventive Principle:

Principle #13The other way round (Inversion)

3Reliability

If the clamping plates are used to grip two wires aligned parallel to the opening/closing direction, then the clamping plates cannot close to a predetermined position, requiring load detection and operation stopping

Engineering Contradiction:

Improvewire grippingVSAvoidbinding operation efficiency

Core Design Contradiction:

ReliabilityVSProductivity

Solution Approach 1:

The patent inverts the conventional wire alignment by positioning wires perpendicular to the opening/closing direction of the clamping plates. This inversion enables the clamping plates to close to the predetermined position without requiring load detection or operation stopping, thereby maintaining both reliable wire gripping and high binding operation efficiency

Inventive Principle:

Principle #13The other way round (Inversion)

Solution Approach 2:

The patent changes the wire alignment from parallel to the opening/closing direction to perpendicular in the radial direction. This dimensional change allows the clamping plates to close properly without encountering excessive load, eliminating the need for load detection systems and operation interruptions, thus maintaining productivity

Inventive Principle:

Principle #17Another dimension (Dimensionality change)
