Solution Overview

Problem

Current ironing cutting apparatuses for self-rolling tubes are prone to deformation and sticking, leading to increased labor costs due to manual intervention.

Innovation Solution

A self-rolling tube ironing cutting device with a positioning member and an ironing cutting module that winds the tube around opposing surfaces to prevent deformation and adhesion, utilizing a feeding mechanism for precise cutting and automated control.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If conventional ironing cutting apparatus is used, then cutting operation can be performed, but self-rolling tube is prone to deformation and sticking

Engineering Contradiction:
Improvecutting precisionVSAvoidtube deformation and sticking
Core Design Contradiction:
Manufacturing precisionVSReliability

Solution Approach 1:

A positioning member is introduced as an intermediary component between the ironing cutting apparatus and the self-rolling tube. The positioning member winds the tube around it, providing support during the cutting operation. This mediator prevents the tube from deforming or sticking by distributing the mechanical stress and maintaining proper positioning throughout the cutting process.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The tube is wound around the positioning member before the ironing cutting operation begins. This preliminary action of positioning and securing the tube on the positioning member prevents deformation during cutting. The tube is pre-configured in a stable arrangement that resists the forces applied during the subsequent cutting operation.

Inventive Principle:
Principle #10Preliminary action

2Manufacturing precision

If manual intervention is used to handle deformation and sticking, then tube quality can be maintained, but labor costs increase

Engineering Contradiction:
Improvetube qualityVSAvoidlabor cost
Core Design Contradiction:
Manufacturing precisionVSProductivity

Solution Approach 1:

The positioning member enables the system to self-correct positioning and support issues during cutting. By winding the tube around the positioning member, the system automatically maintains proper tube configuration and prevents deformation without requiring manual intervention. The装置 serves itself by using the positioning member to prevent the very problems that would otherwise require human workers to address.

Inventive Principle:
Principle #25Self-service

3Device complexity

If self-rolling tube is processed without positioning member, then device complexity is reduced, but deformation and sticking occur

Engineering Contradiction:
Improveapparatus structureVSAvoidtube deformation control
Core Design Contradiction:
Device complexityVSManufacturing precision

Solution Approach 1:

The positioning member serves multiple functions simultaneously: it positions the tube, supports the tube during cutting, prevents deformation, and avoids sticking. This single component performs what would otherwise require multiple separate devices or manual operations, adding minimal complexity while providing comprehensive protection against tube deformation and sticking issues.

Inventive Principle:
Principle #6Universality (Multi-functionality)
