Solution Overview

Problem

Current methods for manufacturing padded garments face challenges with goose feathers, including fabric damage, reduced thermal insulation after washing, and animal welfare concerns, while alternative fillings like wool and cashmere have limitations such as reduced washing resistance and unsuitable natural forms.

Innovation Solution

A method involving carding and air flow processing of cashmere fibers to create fluffy, soft, and bulkier staple fibers suitable for filling padded garments, which are then inserted into fillable portions using a carding machine and beating station to maintain thermal insulation and softness, and a filling plant that includes a carding station, beating station, and push injection means for efficient filling.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Temperature

If goose feathers are used for filling padded garments, then thermal insulation and lightness are improved, but the quill damages and pierces the fabric, reducing reliability

Engineering Contradiction:
Improvethermal insulationVSAvoidfabric integrity
Core Design Contradiction:
TemperatureVSReliability

Solution Approach 1:

The patent extracts and removes the harmful quill portion from the feather structure, using only the soft down fibers for filling. This is achieved through mechanical processing that separates the quill from the down, eliminating the fabric-piercing element while retaining the insulating properties

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent replaces durable but harmful goose feathers with a more affordable, processed alternative - purified down fibers that can be replenished or replaced without damaging the garment structure, as the harmful quill component has been removed

Inventive Principle:
Principle #27Cheap short-living objects (Disposable)

2Temperature

If goose feathers are used for filling padded garments, then initial thermal insulation is improved, but repeated washings bunch the feathers and reduce insulating power

Engineering Contradiction:
Improvethermal insulationVSAvoiddurability after washing
Core Design Contradiction:
TemperatureVSDuration of action of stationary object

Solution Approach 1:

The patent replaces the mechanical interlocking structure of whole feathers with individually processed down fibers that move independently. This substitution prevents the bunching effect during washing, as the loose fibers can redistribute freely rather than being constrained by rigid quill structures

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

Solution Approach 2:

The patent changes the physical state and distribution parameters of the filling material by processing feathers into separated down fibers. This transformation alters how the material responds to washing - from a structured, bunch-prone configuration to a flexible, redistributable fiber mass that maintains insulation

Inventive Principle:
Principle #35Parameter changes

3Object-affected harmful factors

If wool is used as filling material, then animal welfare is improved, but repeated washings remove lanolin and reduce softness and insulating power

Engineering Contradiction:
Improveanimal welfareVSAvoidwashing resistance
Core Design Contradiction:
Object-affected harmful factorsVSDuration of action of stationary object

Solution Approach 1:

The patent extracts the harmful collection practice from the supply chain by using by-product down fibers from feather processing rather than collecting wool from living animals. This eliminates the animal welfare issue while using a material that doesn't rely on lanolin for its properties

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent uses down fibers that are by-products of the feather industry, transforming a waste material into a valuable filling. This alternative to wool doesn't require the same animal husbandry practices and provides a filling that maintains properties through washing

Inventive Principle:
Principle #27Cheap short-living objects (Disposable)

4Temperature

If cashmere is used as filling material, then softness and insulating power are improved, but it is provided in compressed bales with impurities that require extensive processing

Engineering Contradiction:
Improvethermal insulationVSAvoidprocessing complexity
Core Design Contradiction:
TemperatureVSDevice complexity

Solution Approach 1:

The patent merges the carding and cleaning processes into a single integrated treatment step for the down fibers. By combining these operations, the patent simplifies the overall processing required to prepare cashmere or down for filling, reducing the number of separate equipment and process stages needed

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The patent develops a universal processing method that can handle both cashmere and down fibers through the same carding and cleaning system. This multi-functional approach allows the same equipment to process different types of natural fibers, reducing overall device complexity

Inventive Principle:
Principle #6Universality (Multi-functionality)
