Solution Overview

Problem

Conventional methods for imparting insulation, waterproofing, antifouling, antibacterial, and flame retardant properties to fabrics are inefficient, requiring lengthy processing times and prone to functional solution separation during friction or washing due to surface absorption rather than deep penetration.

Innovation Solution

A fabric injection system using a needle to directly inject a functional solution into the fabric, comprising a mixture of aerogel powder, solvents, and additives, with a reciprocating needle mechanism for quick and continuous injection, ensuring deep penetration and retention within the fabric.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a blade is used to permeate a mixture into fabric, then the fabric can be treated with functional solution, but the permeation process takes a long time and processing efficiency is low

Engineering Contradiction:
Improvefunctional solution penetration depthVSAvoidprocessing speed
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The patent replaces the mechanical blade permeation system with an injection needle system that delivers functional solution directly into the fabric interior through injection holes. This substitution of the delivery mechanism enables rapid injection and penetration without the slow blade-based permeation process, thereby improving processing speed while ensuring deep penetration of the functional solution into the fabric.

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

2Reliability

If a functional solution is applied from the outer surface of the fabric, then the fabric can be treated, but the solution cannot penetrate deeply and is easily separated by friction or washing

Engineering Contradiction:
Improvedurability of functional solutionVSAvoidpenetration depth
Core Design Contradiction:
ReliabilityVSManufacturing precision

Solution Approach 1:

The patent inverts the conventional approach of applying functional solution from the outer surface by instead injecting the solution directly into the interior of the fabric through injection holes formed by the needle. This inversion of the delivery direction ensures deep penetration and anchors the functional solution within the fabric structure, preventing separation by friction or washing and thereby improving durability.

Inventive Principle:
Principle #13The other way round (Inversion)

3Reliability

If a blade permeation method is used, then functional properties can be imparted to fabric, but the overall process time is lengthy

Engineering Contradiction:
Improvefunctional properties retentionVSAvoidprocessing time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The patent replaces the time-consuming blade permeation mechanism with a rapid injection needle system that delivers functional solution directly into the fabric. This substitution eliminates the lengthy permeation process while maintaining functional properties retention, as the injection method ensures proper penetration and distribution of the functional solution within the fabric interior.

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