Solution Overview

Problem

Existing fiber waste collection systems in textile machines, such as false-twisting machines, suffer from the discharge of fiber waste mixed with air to the exterior due to inadequate separation methods, leading to potential contamination and inefficiencies.

Innovation Solution

A fiber waste collection device incorporating a cyclone separator system with multiple fiber waste transfer pipes and cyclone separators, each connected one-to-one, effectively separates fiber waste from air within the device, ensuring minimal discharge of fiber waste to the exterior.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If a suction device with a negative pressure pump is used to collect fiber waste, then fiber waste can be suctioned through the suctioning pipe, but air accompanied with fiber waste is discharged to the exterior of the suction device

Engineering Contradiction:
Improvefiber waste collectionVSAvoidair discharge with fiber waste
Core Design Contradiction:
Quantity of substanceVSObject-generated harmful factors

Solution Approach 1:

The patent uses a cyclone separator with a vortex flow path to create a flexible air circulation system. The air flow follows a curved path within the cyclone separator, allowing separation of fiber waste through centrifugal force while maintaining continuous air flow without rigid barriers that would cause pressure loss.

Inventive Principle:
Principle #30Flexible shells and thin films

Solution Approach 2:

The patent changes the pressure parameter within the cyclone separator to achieve separation. By creating a pressure difference between the inlet and outlet of the cyclone separator, fiber waste is separated from the air stream while maintaining negative pressure throughout the system to prevent external air intake.

Inventive Principle:
Principle #35Parameter changes

2Quantity of substance

If multiple suction units are arranged to collect fiber waste from different locations, then comprehensive waste collection is achieved, but the device complexity increases

Engineering Contradiction:
Improvefiber waste collection coverageVSAvoidnumber of transfer pipes and cyclone separators
Core Design Contradiction:
Quantity of substanceVSDevice complexity

Solution Approach 1:

The patent combines multiple cyclone separators into a single integrated structure where they share common walls and support structures. The multiple suction units connect to a common suction source, and the cyclone separators are arranged in a compact configuration that reduces the overall number of independent components.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The patent designs the cyclone separators with multi-functional characteristics where each unit serves both as a separation device and as a structural element supporting the overall framework. The air outlet of each cyclone separator connects to a common air outlet, allowing the system to handle multiple waste streams through a unified discharge path.

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

Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

Function Achieved in This Case

The system efficiently separates fiber waste from air, reducing the volume of air within the collection unit, allowing for larger waste accumulation and fewer collection units, thereby decreasing maintenance frequency and worker burden.

Implementation Method 1

a cyclone separator (30) arranged between the fiber waste transfer pipe (11) and the fiber waste collection unit (13) configured to separate the fiber waste from the air transferred through the fiber waste transfer pipe

Methodology Applied
Scientific EffectCyclone separation: Cyclone Separation

Implementation Method 2

the cyclone separator (30) includes a body portion (32) in a tubular shape connected with the fiber waste transfer pipe (11) such that a longitudinal direction of the fiber waste transfer pipe (11) follows an inner peripheral wall of the body portion (32), the body portion (32) configured to cause the fiber waste transferred through the fiber waste transfer pipe (11) to travel downward along the inner peripheral wall due to a centrifugal force

Methodology Applied
Scientific EffectCentrifugal force: Centrifugal Force
