Solution Overview

Problem

The existing yarn winding systems lack optimization in operation control of automatic winders, which affects production efficiency and working quality, as they do not adaptively adjust processing speed based on the spinning frame's status and completion conditions.

Innovation Solution

A yarn winding system where a spinning frame generates and transmits spinning information to an automatic winder, enabling the winder to control its operation based on processing status and completion conditions, including winding speed and bobbin preparation, using RFID technology for data transfer and storage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If the automatic winder operates at a fixed processing speed, then the operation control is simple, but the production efficiency cannot be optimized according to the spinning frame's processing status

Engineering Contradiction:
Improveproduction efficiencyVSAvoidoperation control complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The automatic winder's processing speed is made dynamic rather than fixed. The control unit adjusts the processing speed in real-time based on the spinning information received from the spinning frame, allowing the system to adapt to varying production conditions and optimize efficiency without requiring complex manual intervention

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

A feedback mechanism is implemented where the spinning frame transmits processing status information to the automatic winder. The control unit receives this feedback and uses it to automatically adjust the winder's operation, creating a closed-loop control system that optimizes productivity while maintaining manageable complexity through automated decision-making

Inventive Principle:
Principle #23Feedback

2Productivity

If the automatic winder does not synchronize with the spinning frame, then the system operation is independent and simple, but the working quality and production efficiency are compromised

Engineering Contradiction:
Improveproduction efficiencyVSAvoidspinning status information
Core Design Contradiction:
ProductivityVSLoss of information

Solution Approach 1:

The spinning frame's processing status information is transmitted to the automatic winder through a feedback channel. This allows the winder to synchronize its operations with the spinning frame's status, ensuring that yarn is wound at the appropriate times and speeds, thereby improving both productivity and working quality without creating information loss

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The transmitted spinning information serves multiple functions: it guides the control unit's speed adjustments, enables synchronization of operations, and provides data for optimizing both spinning and winding processes. This multi-functional use of information maximizes its value while maintaining system coordination

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

3Productivity

If the automatic winder adjusts processing speed based on spinning information, then the production efficiency is optimized, but the system complexity increases

Engineering Contradiction:
Improveproduction efficiencyVSAvoidcontrol system complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The automatic winder's control unit autonomously adjusts its processing speed based on the received spinning information without requiring external intervention. The system serves itself by making real-time decisions to optimize productivity, reducing the need for complex external control mechanisms while maintaining efficient operation

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The control system dynamically adjusts processing parameters based on real-time spinning information. This dynamic adaptation allows the system to optimize productivity through automated speed variations while keeping the control architecture relatively simple, as the adjustments are made algorithmically rather than through complex mechanical or manual systems

Inventive Principle:
Principle #15Dynamics
