Solution Overview

Problem

Existing binding machines for reinforcing bars face issues with inappropriate wire feeding methods, difficulty in guiding wires to the binding mechanism, and accumulation of foreign matters that can cause malfunctions.

Innovation Solution

A binding facility with a wire feeding mechanism that includes a reel accommodation part, a binding mechanism, a wire pullback mechanism, and a wire feeding mechanism with a pullout mechanism to manage wire feeding and guide wires effectively, while also incorporating a mechanism to discharge foreign matters.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a binding machine is used to bind reinforcing bars with wire, then the reinforcing bars are bound effectively, but foreign matters accumulate inside the binding machine causing malfunctions

Engineering Contradiction:

Improvebinding effectivenessVSAvoidforeign matter accumulation

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent extracts and removes foreign matters (wire cuttings, shavings, and other debris) from the binding machine interior using a dedicated discharge mechanism. This includes providing a discharge port and discharge means that actively remove accumulated foreign matters from the binding mechanism area, preventing malfunctions while maintaining binding effectiveness.

Inventive Principle:

Principle #2Taking out (Extraction)

2Adaptability or versatility

If the binding machine is moved to binding-possible positions, then it can bind reinforcing bars at different locations, but it becomes difficult to guide the wire from the feeding mechanism to the binding mechanism

Engineering Contradiction:

Improveposition flexibilityVSAvoidwire guidance

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

The patent employs a dynamic wire guide mechanism that can move together with the binding mechanism. The wire guide is coupled to the binding mechanism so that when the binding mechanism moves to different binding positions, the wire guide moves accordingly, maintaining proper wire alignment and guidance throughout the binding operation.

Inventive Principle:

Principle #15Dynamics

3Productivity

If the binding machine is always used upward oriented from below, then it can bind reinforcing bars effectively, but foreign matters easily enter and accumulate in the binding machine

Engineering Contradiction:

Improvebinding efficiencyVSAvoidforeign matter entry

Core Design Contradiction:

ProductivityVSObject-affected harmful factors

Solution Approach 1:

The patent implements preliminary protective measures by providing a cover that can close the discharge port and wire guide opening when not in use. This cover prevents foreign matters from entering the binding mechanism while maintaining the upward orientation binding efficiency. The cover is designed to be opened only when wire feeding or foreign matter discharge is required.

Inventive Principle:

Principle #9Preliminary anti-action
