Solution Overview

Problem

Conventional plant nutrient solutions rely heavily on synthetic compounds, leading to environmental pollution and inefficient retention of natural active ingredients in seaweed, while existing methods for seaweed extraction are costly and inefficient, particularly due to excessive use of protease and insufficient enzymatic hydrolysis.

Innovation Solution

A method involving the enzymatic hydrolysis of fresh seaweed pulp using a composite microbial enzyme mixture, comprising cellulase, pectinase, protease, and amylase, under controlled conditions to produce a plant nutrient solution with enhanced activity and reduced environmental impact.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If conventional alkaline extraction and high-temperature concentration methods are used for seaweed processing, then extraction efficiency is improved, but natural active ingredients are destroyed

Engineering Contradiction:
Improveextraction efficiencyVSAvoidretention of active ingredients
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The patent changes the extraction parameters from conventional alkaline solution and high temperature to microbial enzyme treatment at lower temperatures. Specifically, it uses cellulase, pectinase, and protease enzymes to hydrolyze seaweed components under mild conditions (pH 4-7, temperature 20-50℃), which effectively extracts active ingredients while preserving their biological activity and avoiding thermal degradation.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent replaces the mechanical-chemical extraction method (alkaline solution + high-temperature concentration) with a biological enzymatic hydrolysis system. Microbial enzymes catalyze the breakdown of seaweed cell walls and macromolecules, substituting the harsh physical-chemical process with a gentler biological process that maintains ingredient integrity while achieving efficient extraction.

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

2Reliability

If the same amount of protease as other enzymes is used in seaweed hydrolysis, then comprehensive enzyme coverage is improved, but production cost increases

Engineering Contradiction:
Improveenzymatic hydrolysis completenessVSAvoidproduction cost
Core Design Contradiction:
ReliabilityVSQuantity of substance

Solution Approach 1:

The patent applies different enzyme quantities based on the specific compositional needs of seaweed. Since seaweed contains abundant cellulose and pectin but relatively less protein, the formulation uses higher amounts of cellulase (40-60 units/g seaweed) and pectinase (20-40 units/g seaweed) while using moderate protease (10-20 units/g seaweed). This localized optimization ensures complete hydrolysis of dominant components without wasting expensive enzymes on minor components.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The patent applies excessive action principle by using sufficient cellulase and pectinase to completely hydrolyze the abundant cellulose and pectin in seaweed, while using moderate protease since protein content is lower. This targeted excessive action on critical components ensures thorough hydrolysis without unnecessary enzyme expenditure on already-sufficient areas.

Inventive Principle:
Principle #16Partial or excessive action

3Productivity

If heavy use of chemical fertilizer is applied to increase crop yield, then agricultural productivity is improved, but environmental pollution and soil degradation worsen

Engineering Contradiction:
Improvecrop yieldVSAvoidenvironmental pollution
Core Design Contradiction:
ProductivityVSObject-generated harmful factors

Solution Approach 1:

The patent converts the problem of seaweed waste (which would otherwise be discarded or cause pollution) into a beneficial plant nutrient solution. By using microbial enzymes to hydrolyze seaweed, it transforms organic matter that could decompose anaerobically and pollute the environment into a valuable fertilizer containing amino acids, peptides, and soluble carbohydrates that promote plant growth while improving soil health.

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

Solution Approach 2:

The patent introduces microbial enzymes as an intermediary substance to transform seaweed into a plant-nutrient solution. These enzymes act as catalysts that break down complex seaweed macromolecules into plant-absorbable forms, creating a bridge between seaweed waste and usable fertilizer, thereby eliminating the need for harmful chemical fertilizers while maintaining crop productivity.

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

The present invention relates to a composite microorganism enzyme, a method for preparing a plant nutrient solution by using the composite microorganism enzyme, and a fertilizer synergist. The method comprises the following steps: mixing fresh kelp pulp with a composite microorganism enzyme; and performing enzymolysis on the mixture of the fresh kelp pulp and the composite microorganism enzyme in an enzymolysis vessel to obtain the plant nutrient solution; the composite microorganism enzyme comprises more than one kind each of cellulase, pectinase, protease and amylase, the mass percentage of the cellulases and the pectinases being far greater than that of the proteases and the amylases. The present method for preparing a plant nutrient solution involves a simple enzymolysis process, mild reaction conditions, low costs and no other chemical compositions during the reaction processes, and maintains more of the active ingredients of the fresh kelp.
