Solution Overview

Problem

Current ball winding machines cannot precisely control or program the initial and final colors of a ball of thread with multiple color stretches, leading to uncertainty and inefficiency in producing identical textile products, resulting in material waste.

Innovation Solution

A control and programming system for ball winding machines that includes a chromatic characteristic acquisition device, a thread movement system using compressed air, and a cutting mechanism, allowing for precise determination and control of the initial and final colors by learning the selected color and activating the cutting device at the appropriate interval.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If prior art ball winding machines are used, then the winding process can be completed, but the initial and final colors of the ball cannot be precisely controlled or determined

Engineering Contradiction:
Improvecolor determination precisionVSAvoidcolor control reliability
Core Design Contradiction:
Measurement precisionVSReliability

Solution Approach 1:

The system performs preliminary learning of the color sequence pattern before actual ball production. The control unit stores the identified color sequence and uses it to predeterminedly control the winding process, ensuring the ball starts and ends with the same color without requiring real-time adjustment during winding.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system uses a detection device to acquire chromatic characteristics of the thread and provides feedback to the control unit. This feedback loop enables the system to identify the color sequence pattern and adjust the winding process to achieve predetermined initial and final colors.

Inventive Principle:
Principle #23Feedback

2Productivity

If prior art systems are used, then ball production can proceed, but material waste is generated due to inability to produce identical products

Engineering Contradiction:
Improveproduction efficiencyVSAvoidmaterial waste
Core Design Contradiction:
ProductivityVSLoss of substance

Solution Approach 1:

The system predeterminedly programs the color sequence pattern before production. By knowing in advance which colors will be at the beginning and end of the ball, the system eliminates the need to discard balls that don't meet color specifications, thereby reducing material waste while maintaining production efficiency.

Inventive Principle:
Principle #10Preliminary action

3Ease of operation

If prior art systems are used, then the winding process can be completed, but uncertainty exists in processing for the final user

Engineering Contradiction:
Improveprocessing certaintyVSAvoidcolor information确定性
Core Design Contradiction:
Ease of operationVSLoss of information

Solution Approach 1:

The detection device continuously monitors the chromatic characteristics of the thread and provides feedback to the control unit. This real-time information feedback eliminates uncertainty by providing precise knowledge of the color sequence, enabling the final user to process balls with confidence that they will be identical.

Inventive Principle:
Principle #23Feedback

4Measurement precision

If a chromatic characteristic acquisition device is added, then color control is improved, but device complexity increases

Engineering Contradiction:
Improvechromatic measurement precisionVSAvoidsystem complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The control unit serves multiple functions: it controls the winding machine operation, processes chromatic data from the detection device, identifies color sequence patterns, and predeterminedly programs the ball production. By making the control unit multi-functional, the system achieves precise color control without proportionally increasing overall system complexity.

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