Solution Overview

Problem

Existing thread feeding devices for textile machines are difficult to clean, leading to issues with dust and fluff deposits, which requires disassembly and reassembly, a costly and inefficient process.

Innovation Solution

A thread feeding device with a magnet arrangement for securing the storage device to the housing, a drivable shaft for winding the thread, and a locking mechanism that allows the unit to be moved along a cleaning path, enabling easy removal of deposits without disassembly, by releasing the locking element and pulling the unit off the winding element.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the storage device is securely fixed to the housing using a magnetic arrangement, then the storage device remains stable during operation, but the device becomes difficult to clean due to accumulated deposits

Engineering Contradiction:
Improvestability of storage deviceVSAvoidease of cleaning
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The device is divided into two separable parts: the storage device with the second magnetic unit and the housing with the first magnetic unit. The locking element enables controlled separation of these segments for cleaning while maintaining secure connection during operation. This segmentation allows the storage device to be easily removed for cleaning by releasing the locking element, resolving the contradiction between stability and ease of cleaning.

Inventive Principle:
Principle #1Segmentation

2Stability of the object's composition

If the locking device secures the bearing arrangement to the shaft, then the components remain firmly positioned during operation, but disassembly and reassembly become time-consuming

Engineering Contradiction:
Improveposition stability of bearing arrangementVSAvoidtime for disassembly and reassembly
Core Design Contradiction:
Stability of the object's compositionVSLoss of time

Solution Approach 1:

The locking device replaces traditional mechanical fastening methods (screws, clips, or permanent mounting) with a magnetic locking mechanism. The locking element, when engaged, creates a strong magnetic attraction that firmly secures the bearing arrangement to the shaft during operation. For cleaning, the locking element can be easily released by pulling it off, allowing quick separation without tools or complex disassembly procedures. This magnetic-based system resolves the contradiction by providing both secure positioning and rapid release.

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

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 solution simplifies the cleaning process by creating a free space between the unit and the take-up element, allowing for effective removal of contaminants like fluff and dust without disassembling the device, maintaining operational functionality without additional adjustments.

Implementation Method 1

The storage device is secured to the housing by a magnetic arrangement, which has a first magnetic unit on the housing and a second magnetic unit on the storage device
