Solution Overview

Problem

Current methods for separating natural fibers from bundles, such as those used in linen production, are inefficient and environmentally harmful, as they rely on time-consuming natural roasting or costly and energy-intensive mechanical processes, and chemical processes that damage the environment.

Innovation Solution

Applying an electric field with a flow of electric current, using deionized water, to break down the natural adhesive pectins, allowing for easier mechanical separation of fibers.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If natural roasting is used to separate fibers, then fiber separation is achieved, but the process is time-consuming and dependent on weather conditions

Engineering Contradiction:
Improvefiber separation speedVSAvoidroasting time
Core Design Contradiction:
ProductivityVSLoss of time

Solution Approach 1:

The patent replaces the biological/chemical process of natural roasting with an electrical field-based mechanism. Electric current applied to wet fiber bundles generates heat and direct electrical action that decomposes pectin adhesives, achieving fiber separation without weather-dependent biological decomposition.

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

Solution Approach 2:

The patent changes the fundamental parameter of separation from time-based biological decomposition to electricity-based decomposition. By applying electric current (measured in amperes) to wet fibers, the process achieves rapid pectin breakdown in minutes rather than days, fundamentally altering the separation mechanism.

Inventive Principle:
Principle #35Parameter changes

2Productivity

If intensive mechanical processes are used to separate fibers, then separation effectiveness increases, but fiber breakage and destruction occur

Engineering Contradiction:
Improveseparation effectivenessVSAvoidfiber integrity
Core Design Contradiction:
ProductivityVSStrength

Solution Approach 1:

The patent substitutes direct mechanical force with electrical field action. The electric current penetrates the fiber bundle and decomposes pectin adhesives from the inside, eliminating the need for external mechanical force that would cause fiber breakage while achieving complete separation.

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

Solution Approach 2:

The patent introduces water as an intermediary medium that enables electrical current to act on pectin adhesives. Wet fibers conduct electricity better, allowing the electrical field to effectively decompose bonds without requiring direct mechanical contact that would damage fibers.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Productivity

If chemical processes are used to break down pectin, then fiber separation is achieved, but environmental harm and cost increase

Engineering Contradiction:
Improveseparation efficiencyVSAvoidenvironmental impact
Core Design Contradiction:
ProductivityVSObject-affected harmful factors

Solution Approach 1:

The patent replaces chemical processes with physical electrical processes. Electric current applied to wet fibers generates heat and direct electrical decomposition of pectin, eliminating the need for harmful chemicals while achieving the same separation effect.

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

Solution Approach 2:

The patent converts the naturally occurring water in fibers from a potential interference into a beneficial conductor. Water enables electrical current to flow through the fiber bundle, allowing electrical decomposition of pectin without requiring additional chemicals, thus turning a neutral substance into a useful medium.

Inventive Principle:
Principle #22Blessing in disguise (Convert harm into benefit)

Applied Scientific Principles

AI summary

The method involves exposing the fiber bundles in contact with water to an electric field strength and an electrical current flow resulting from it. The required electric field is homogeneously and nonhomogeneously formed in arbitrary shape, particularly as plate capacitor or a coaxial structure. The fiber bundles are additionally moved in the water bath for the duration of action of the electric field. The fiber bundles to be treated are moistened or wetted.
