Solution Overview

Problem

Existing methods for producing soil improvers require the addition of numerous additives to achieve desired nutrient levels, making them costly and inefficient.

Innovation Solution

A method involving the composition of a starting material using a mixture of river sediments with varying nutrient contents, optimized by a computer algorithm, reduces the need for additives by ensuring higher inherent nutrient levels, and includes aerobic composting and addition of mycorrhiza and living organisms to create a nutrient-rich, mini-ecosystem.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If a starting material containing only one river sediment is used, then the production process is simple and成本低, but the nutrient content is insufficient requiring many additives

Engineering Contradiction:
Improvenutrient contentVSAvoidstarting material composition
Core Design Contradiction:
Quantity of substanceVSDevice complexity

Solution Approach 1:

The patent combines multiple river sediments from different locations into a composite starting material. Each river sediment contributes different nutrient profiles, and their combination creates a synergistic effect that achieves higher overall nutrient content than any single sediment alone, reducing the need for additional nutrient additives.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The invention creates a composite starting material by mixing different river sediments with varying nutrient compositions. This composite approach allows optimization of nutrient content through selective combination of sediments with complementary nutrient profiles, thereby reducing dependency on external nutrient additives.

Inventive Principle:
Principle #40Composite materials

2Quantity of substance

If many additives are added to achieve desired nutrient levels, then the nutrient content is sufficient, but the production cost increases

Engineering Contradiction:
Improvedesired nutrient levelsVSAvoidproduction cost
Core Design Contradiction:
Quantity of substanceVSEase of manufacture

Solution Approach 1:

The patent performs preliminary enrichment of nutrients by selecting and combining river sediments that naturally contain the desired nutrient profiles before the main production process. This pre-positioning of nutrients in the starting material reduces or eliminates the need for expensive nutrient additives during production.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The invention enables the starting material to provide its own nutrients through the natural nutrient content of combined river sediments. The system serves itself by using the inherent nutrients in the sediments rather than requiring external nutrient supplements, thereby reducing production costs.

Inventive Principle:
Principle #25Self-service

3Manufacturing precision

If a single river sediment is used as starting material, then the process is straightforward, but the nutrient levels do not approximate desired levels

Engineering Contradiction:
Improvenutrient level approximationVSAvoidsediment composition
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The patent applies local quality by selecting river sediments with specific nutrient characteristics suited for particular soil improvement needs. Different sediments are chosen for their local nutrient strengths, and their combination creates a starting material with precisely tailored nutrient profiles that closely match desired levels.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The invention changes the parameters of the starting material by varying the types, sources, and proportions of river sediments used. By adjusting these parameters, the nutrient content of the starting material can be optimized to closely approximate desired nutrient levels, reducing the need for corrective additives.

Inventive Principle:
Principle #35Parameter changes

AI summary

Method for producing a soil improver 1 with desired levels of desired nutrients, comprising the composition of a starting material 13 and the addition of additives 15, whereby a river sediment 5 with levels of nutrients is taken as the starting material 13 when composing the starting material. When composing the starting material 13, at least one further river sediment 5 with different nutrient contents from the previously mentioned river sediment is added to the river sediment, in such a way that, by a correct choice of the added river sediment or river sediments and a correct choice of the quantities of the added river sediment or river sediments, the desired nutrient content in the starting material 13 is increased compared to the previous composition of the starting material which contained only one river sediment.
