Solution Overview

Problem

Existing methods for cutting manufactured articles, such as tubes, result in waste and increased equipment costs when sampling is required for quality control, as they necessitate additional cutting and repositioning steps.

Innovation Solution

A method that synchronizes the speed of a mobile cutting device with the advancement of the manufactured article to position it accurately for cutting, allowing for efficient cutting and sample collection within a single cycle, reducing waste and equipment needs by enabling two cuts with a single device.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a special device is used to collect and re-cut a segment for sample extraction, then quality control sampling is enabled, but equipment complexity and costs increase

Engineering Contradiction:
Improvequality control sampling capabilityVSAvoidequipment complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The cutting device is designed to perform multiple functions: it can cut segments of predetermined length for production and also cut samples of variable length for quality control. The device includes a control system that can switch between different cutting modes (first cutting zone for production segments, second cutting zone for samples), eliminating the need for separate sampling equipment.

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

2Adaptability or versatility

If a special device is used to collect and re-position samples, then quality control sampling is enabled, but operational costs increase

Engineering Contradiction:
Improvequality control sampling capabilityVSAvoidoperational costs
Core Design Contradiction:
Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The same cutting device performs both production cutting and sample extraction, eliminating the need for separate sampling equipment. The control system allows the device to switch between cutting modes, reducing equipment investment and operational costs while maintaining quality control capabilities.

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

3Manufacturing precision

If the cutting device is synchronized with article advancement for precise positioning, then cutting precision is improved, but control complexity increases

Engineering Contradiction:
Improvecutting position precisionVSAvoidsynchronization system complexity
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The control system receives information about the position of the manufactured article and adjusts the cutting device's position accordingly. This feedback mechanism ensures that the cutting device is accurately positioned at the predetermined first or second cutting zones, achieving precise cutting while managing control complexity through automated feedback loops.

Inventive Principle:
Principle #23Feedback
