Solution Overview

Problem

Existing thread consuming devices, such as embroidery machines, require multiple threads of different colors for multi-colored patterns, which is costly and space-consuming, and existing in-line coloration systems can only handle one thread at a time.

Innovation Solution

A system with a treatment unit that includes multiple nozzles divided into separate dispensing zones, allowing independent control for simultaneous treatment of multiple threads with different coating substances.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple separate threads of different colors are used for multi-colored patterns, then color variety is achieved, but device complexity and space requirements increase

Engineering Contradiction:
Improvecolor varietyVSAvoidthread management complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

A single thread is used to perform multiple functions by applying different coating substances (colors) in-line during processing. The treatment unit with multiple nozzles can apply different colors to the same thread sequentially, replacing the need for multiple pre-colored threads and simplifying thread management while maintaining color variety.

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

Solution Approach 2:

The coating substances are applied to the thread in advance before the thread reaches the consuming device. This preliminary coloring action allows the thread to be prepared with specific color patterns beforehand, eliminating the need for complex real-time thread switching and management during the consuming process.

Inventive Principle:
Principle #10Preliminary action

2Productivity

If a single treatment unit treats multiple threads simultaneously, then productivity increases, but control complexity increases

Engineering Contradiction:
Improvethread treatment throughputVSAvoidcontrol system complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The treatment unit is divided into multiple dispensing zones, with each zone containing nozzles dedicated to treating specific threads. This segmentation allows independent control of each zone, enabling simultaneous treatment of multiple threads while maintaining simple control logic for each individual zone. The control unit can activate specific zones based on which threads need treatment, managing complexity through modular organization.

Inventive Principle:
Principle #1Segmentation

3Manufacturing precision

If in-line coloring is applied to improve color quality, then color consistency improves, but the system can only handle one thread at a time

Engineering Contradiction:
Improvecolor consistencyVSAvoidthread processing capacity
Core Design Contradiction:
Manufacturing precisionVSProductivity

Solution Approach 1:

Multiple treatment functions are merged into a single treatment unit. The unit combines multiple nozzles distributed in different dispensing zones, allowing it to treat multiple threads simultaneously while maintaining the in-line coloring advantage of consistent color application. This merging preserves color consistency while increasing processing capacity.

Inventive Principle:
Principle #5Merging (Combining)
