Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If manual donning is used in twisting machines, then operators can perform donning operations, but the donning time is long, efficiency is low, and labor intensity is high

Engineering Contradiction:

Improvedonning efficiencyVSAvoiddonning time

Core Design Contradiction:

ProductivityVSLoss of time

Solution Approach 1:

The system enables automatic donning where the machine serves itself by automatically conveying yarn packages from the yarn package library to the twisting positions, eliminating the need for manual intervention in the donning process

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The patent replaces manual mechanical donning operations with an automated conveying system that uses conveyors and positioning mechanisms to transport and place yarn packages automatically at the required positions

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Extent of automation

If robotic donning with AGV is used, then automation is improved, but the robot has weak ability to dodge operators, causing disruptions and control difficulty

Engineering Contradiction:

Improveautomation levelVSAvoidoperator interaction

Core Design Contradiction:

Extent of automationVSEase of operation

Solution Approach 1:

The system is divided into separate functional zones: an automated yarn package library area and a twisting operation area. The automated conveying system operates independently in its zone, while operators work independently in theirs, minimizing interaction and disruption

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

An automated conveying system acts as an intermediary between the yarn package library and the twisting positions, handling all yarn package transport tasks automatically without requiring robots to navigate through operator workspaces

Inventive Principle:

Principle #24Intermediary (Mediator)

3Extent of automation

If existing automatic doffing systems are used, then doffing is automated, but manual donning is still required after doffing

Engineering Contradiction:

Improvedoffing automationVSAvoidoverall donning efficiency

Core Design Contradiction:

Extent of automationVSProductivity

Solution Approach 1:

The automated yarn package conveying system serves multiple functions: it supplies yarn packages for donning, facilitates doffing operations, and prepares for the next donning cycle, making the system universally applicable to both donning and doffing processes

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The conveying system operates continuously throughout the entire production cycle, maintaining readiness for both donning and doffing operations without interruption, ensuring that yarn packages are always available when needed

Inventive Principle:

Principle #20Continuity of useful action
