Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If manual control methods are used for yarn spindle transit, then operational flexibility is maintained, but transiting efficiency and productivity are insufficient

Engineering Contradiction:

Improvetransiting efficiencyVSAvoidmanual intervention

Core Design Contradiction:

ProductivityVSExtent of automation

Solution Approach 1:

The system enables automatic transit control where the PLC autonomously manages yarn spindle movement between workstations based on production status data, eliminating the need for manual intervention and significantly improving transiting efficiency

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The patent replaces manual mechanical control with an automated PLC-based control system that uses electronic signals and programmed logic to manage yarn spindle transit, thereby increasing productivity while reducing human labor

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Productivity

If automated transit control is implemented, then transiting efficiency is improved, but system complexity increases

Engineering Contradiction:

Improvetransiting efficiencyVSAvoidcontrol system complexity

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The PLC serves as an intermediary control device that simplifies the system architecture by centralizing the control logic for yarn spindle transit, managing communication between workstations and reducing overall system complexity while maintaining high automation efficiency

Inventive Principle:

Principle #24Intermediary (Mediator)

3Loss of substance

If existing control systems are used, then device simplicity is maintained, but material waste occurs and production costs increase

Engineering Contradiction:

Improvematerial wasteVSAvoidcontrol system structure

Core Design Contradiction:

Loss of substanceVSDevice complexity

Solution Approach 1:

The system implements feedback control where the PLC continuously monitors production status data from workstations and adjusts yarn spindle transit decisions in real-time, preventing material waste by ensuring spindles are only transferred when appropriate, thereby reducing losses without requiring overly complex additional hardware

Inventive Principle:

Principle #23Feedback
