Solution Overview

Problem

Current methods for managing keratin waste, such as pig hair, are inefficient and result in environmental pollution, as keratin is not digestible by animals or absorbable by plants in its raw form.

Innovation Solution

A process involving microbial keratin decomposition followed by enzymatic hydrolysis to convert keratin into bio-available peptides and amino acids, which can be used as a plant bio-stimulant or in animal nutrition.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If keratin waste is disposed of directly, then disposal is simple, but environmental pollution occurs and protein material is wasted

Engineering Contradiction:
Improvedisposal simplicityVSAvoidenvironmental pollution
Core Design Contradiction:
Ease of manufactureVSObject-generated harmful factors

Solution Approach 1:

The patent converts keratin waste, which causes environmental pollution when disposed of directly, into valuable bio-stimulants through microbial decomposition and enzymatic hydrolysis. The harmful waste material is transformed into beneficial peptides and amino acids that can enhance plant growth, thus converting an environmental problem into an economic and ecological benefit

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

Solution Approach 2:

Instead of discarding keratin waste directly, the patent recovers valuable protein materials through a two-step process: microbial decomposition breaks down the keratin structure, and enzymatic hydrolysis extracts peptides and amino acids. This recovery process prevents pollution while generating useful products for agriculture

Inventive Principle:
Principle #34Discarding and recovering

2Ease of manufacture

If keratin is used directly in animal nutrition or plant cultivation, then no processing is needed, but animals cannot digest it and plants cannot absorb it

Engineering Contradiction:
Improveprocessing simplicityVSAvoidbioavailability
Core Design Contradiction:
Ease of manufactureVSEase of operation

Solution Approach 1:

The patent applies preliminary actions to keratin waste before its intended use: microbial decomposition pre-breaks down the resistant keratin structure, and enzymatic hydrolysis further decomposes it into peptides and amino acids. These preliminary processing steps make the material bioavailable for animal nutrition and plant cultivation without requiring complex processing at the point of use

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent introduces microbial consortia and enzymes as intermediaries to facilitate the conversion of keratin into bioavailable forms. These biological mediators break down the complex keratin structure into simpler peptides and amino acids that can be readily absorbed by plants and animals, bridging the gap between the raw material and its intended application

Inventive Principle:
Principle #24Intermediary (Mediator)

3Productivity

If chemical hydrolysis methods are used to convert keratin, then conversion efficiency is high, but hazardous chemicals and reactions are involved

Engineering Contradiction:
Improveconversion efficiencyVSAvoidhazardous chemicals
Core Design Contradiction:
ProductivityVSObject-affected harmful factors

Solution Approach 1:

The patent replaces chemical hydrolysis methods with biological processing systems. Instead of using harsh chemicals and high-energy reactions, the patent employs microbial consortia and enzymes to decompose keratin under milder conditions. This substitution maintains conversion efficiency while eliminating the need for hazardous chemicals and reducing environmental impact

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

Solution Approach 2:

The patent changes the processing parameters from extreme chemical conditions to milder biological conditions. By using microbial decomposition at controlled temperatures and pH levels, followed by enzymatic hydrolysis under optimized conditions, the patent achieves effective keratin conversion without requiring the harsh chemical environment needed for traditional chemical hydrolysis methods

Inventive Principle:
Principle #35Parameter changes
