Solution Overview

Problem

Existing JET treatment systems face challenges in orderly placement of textile goods in storage areas, leading to disordered deposition, high pull-off forces, and inefficient use of storage space, which increases liquor content and operational costs.

Innovation Solution

A device with a drive mechanism for the goods outlet that allows rotation and longitudinal movement along a closed path, enabling precise sheeting and deposition of textile materials with reduced tensile forces, eliminating the need for additional coilers and optimizing storage space usage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Volume of moving object

If a left-right stacker is used to deposit the running strand in the storage area, then the storage depth can be limited to 35-50 cm, but the strand is deposited in a disordered manner and high pull-off forces are required

Engineering Contradiction:
Improvestorage depthVSAvoidordering of strand deposition
Core Design Contradiction:
Volume of moving objectVSManufacturing precision

Solution Approach 1:

The transport nozzle arrangement is made dynamically movable in the longitudinal direction of the treatment container, allowing it to change position during operation. This dynamic positioning enables the strand to be deposited in an ordered manner along the longitudinal axis while maintaining limited storage depth, resolving the contradiction between storage depth limitation and deposition orderliness.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The invention transitions from transverse deposition (left-right stacking) to longitudinal deposition along the container axis. By changing the dimension of deposition from lateral to longitudinal, the system achieves better ordering and reduces the need for deep storage while maintaining efficient space utilization.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Manufacturing precision

If the storage depth is increased to improve strand ordering, then the strand can be deposited more orderly, but the folds fall inward towards the center and require great effort to pull off

Engineering Contradiction:
Improveordering of strand depositionVSAvoidpull-off force
Core Design Contradiction:
Manufacturing precisionVSForce

Solution Approach 1:

The movable transport nozzle arrangement dynamically adjusts its position to deposit strands in an ordered longitudinal pattern. This dynamic deposition creates accessible fold structures that can be easily pulled off without requiring excessive force, even while maintaining good ordering.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The strand deposition follows a curved or spiral path along the longitudinal axis, creating rounded fold patterns rather than sharp angular folds. This curvature allows folds to open naturally and be pulled off with minimal force while maintaining excellent ordering.

Inventive Principle:
Principle #14Spheroidality (Curvature)

3Reliability

If a reel is added to transport the strand, then the strand can be conveyed more reliably, but the device complexity increases and expensive sensors are required

Engineering Contradiction:
Improvestrand transport reliabilityVSAvoidnumber of components
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The invention extracts and removes the reel component from the system entirely. Instead of using a reel to transport and store the strand, the system relies on the movable transport nozzle arrangement to directly deposit strands in an ordered manner into a shallow storage area, eliminating the need for complex reel mechanisms and associated sensors.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The transport nozzle arrangement serves dual functions: it both transports the strand from the treatment zone and deposits it in an ordered storage pattern. This self-service capability eliminates the need for separate reel components, reducing system complexity while maintaining reliable strand handling.

Inventive Principle:
Principle #25Self-service
