Innovation Solution

An automatic color mix dyeing process involving an automatic shaping device, a dyeing apparatus with multiple spray devices for simultaneous multi-color application, and a vapor device for color fixing, which allows for the dyeing of various materials like polyester, nylon, and cotton in a single process without using water, using a conveyor system and control devices to manage dye application and temperature.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If conventional tank immersion dyeing is used, then cotton materials can be dyed, but polyester and nylon cannot be dyed effectively

Engineering Contradiction:
Improvematerial compatibilityVSAvoiddyeing effectiveness
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The patent applies parameter changes by controlling temperature parameters to match material requirements. The system heats the tank to different temperature ranges: lower temperatures for cotton and higher temperatures for polyester and nylon, enabling effective dyeing of various materials by adjusting the thermal parameter

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent implements universality by creating a multi-functional dyeing system that can handle different material types (cotton, polyester, nylon) and produce multiple colors in a single process. The automated spray system with multiple dye containers and the programmable temperature control enable the same apparatus to serve multiple material types and color combinations

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

2Adaptability or versatility

If multiple dyeing processes are used for multi-color products, then color variety is achieved, but manufacturing complexity increases

Engineering Contradiction:
Improvecolor varietyVSAvoidprocess complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent merges multiple dyeing operations into a single integrated process. The automated system combines multiple dye containers, spray nozzles, temperature control, and timing mechanisms into one coordinated operation that applies multiple colors sequentially in a single batch, eliminating the need for separate dyeing processes

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The patent replaces manual, multi-step mechanical dyeing processes with an automated control system. The microprocessor-controlled apparatus automatically manages dye selection, spray timing, temperature adjustment, and cycle sequencing, reducing operational complexity while maintaining color variety

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

3Reliability

If conventional dyeing processes are used, then dyeing can be performed, but large quantities of water are consumed

Engineering Contradiction:
Improvedyeing capabilityVSAvoidwater consumption
Core Design Contradiction:
ReliabilityVSQuantity of substance

Solution Approach 1:

The patent uses hydraulic principles through the pump system that circulates dye solutions through the spray nozzles. This controlled fluid delivery system applies dye efficiently as a mist or spray directly onto the material, significantly reducing water consumption compared to traditional tank immersion methods where large volumes of water are required

Inventive Principle:
Principle #29Pneumatics and hydraulics

4Reliability

If conventional dyeing processes are used, then dyeing can be performed, but harmful dye solutions are generated

Engineering Contradiction:
Improvedyeing effectivenessVSAvoidenvironmental harm
Core Design Contradiction:
ReliabilityVSObject-generated harmful factors

Solution Approach 1:

The patent implements recovery by circulating and reusing the dye solution through the pump system. The solution is continuously recirculated through the spray system and returned to the tank for reuse, minimizing waste discharge. The system also allows for concentrated dye application reducing the volume of harmful solution that requires treatment

Inventive Principle:
Principle #34Discarding and recovering
