Solution Overview

Problem

Existing long-storage machines for textile goods face challenges in treating a wide range of textile materials due to varying coefficients of friction, leading to issues like fabric damage, wrinkles, and uneven treatment, as they often rely on fixed reel systems and sliding floors with predefined inclinations that are not adaptable to different materials.

Innovation Solution

The machine features an adjustable sliding floor inclination within the treatment container, allowing for customizable angles between 6 and 14 degrees, and a trough-shaped sliding floor that can be concavely curved, along with a transport nozzle arrangement that operates without a reel, enabling gentle handling of textile goods by minimizing tensile forces and optimizing liquor ratios.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Speed

If a fixed reel system is used to drive the material strand, then the material can be transported through the treatment vessel, but surface damage occurs due to abrasion and fabric displacement from contact with the reel

Engineering Contradiction:
Improvematerial strand transport speedVSAvoidsurface damage to textile material
Core Design Contradiction:
SpeedVSObject-affected harmful factors

Solution Approach 1:

The invention removes the reel component entirely from the system. Instead of using a mechanical reel to drive the material strand, the patent employs a transport nozzle assembly that propels the strand through the treatment vessel using a fluid medium, thereby eliminating the source of surface damage while maintaining transport functionality

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The mechanical reel-based drive system is replaced with a fluid-dynamic transport system. The transport nozzle assembly uses a fluid medium (liquid or gas) to propel the material strand, substituting mechanical contact with fluid-based propulsion to avoid abrasion and surface damage

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

2Speed

If a sliding floor with fixed inclination is used in the storage section, then material can be transported by gravity effect, but fabric compaction and wrinkles occur due to varying coefficients of friction for different textile materials

Engineering Contradiction:
Improvematerial bundle transport speedVSAvoidfabric compaction and wrinkles
Core Design Contradiction:
SpeedVSObject-affected harmful factors

Solution Approach 1:

The sliding floor inclination is made adjustable rather than fixed. The patent incorporates a mechanism that allows the inclination angle of the sliding floor to be dynamically changed according to the specific textile material being processed, enabling optimization of the gravity effect for different friction coefficients and preventing fabric compaction and wrinkles

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The inclination angle parameter of the sliding floor is made variable. By adjusting this geometric parameter according to the specific textile material's properties (particularly its coefficient of friction), the system optimizes material flow and prevents harmful effects like compaction and wrinkling

Inventive Principle:
Principle #35Parameter changes

3Object-affected harmful factors

If the sliding floor is made concavely curved to prevent fabric compaction, then fabric handling is improved for some materials, but the design becomes less suitable for other textile types with different friction characteristics

Engineering Contradiction:
Improvefabric compaction reductionVSAvoidsuitability for different textile types
Core Design Contradiction:
Object-affected harmful factorsVSAdaptability or versatility

Solution Approach 1:

The sliding floor geometry is made dynamically adjustable. Instead of a fixed concave curve that may not suit all materials, the patent allows the inclination angle to be changed, providing adaptability to different textile types while maintaining the benefit of reduced fabric compaction through optimized gravitational flow

Inventive Principle:
Principle #15Dynamics
