Innovation Solution

A method for preparing an organic complex microelement fertilizer using chitosan oligosaccharide, earthworm dung, silkworm sand, tartaric acid, humic acid, and various metal sulfates, with specific dissolution and complexation steps, to create a fertilizer with enhanced trace element effectiveness and stability.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If common microelement fertilizers for farmland soil are used in engineering wound soil remediation, then the fertilizer can be applied, but the nutrient supply is not coordinated and fertilizer utilization rate is low

Engineering Contradiction:
Improveadaptability to engineering wound soilVSAvoidfertilizer utilization rate
Core Design Contradiction:
Adaptability or versatilityVSProductivity

Solution Approach 1:

The patent formulates a specialized microelement fertilizer tailored specifically for engineering wound soil conditions, with customized nutrient composition including organic matter (10-30%), nitrogen (2-5%), phosphorus (1-3%), potassium (2-5%), and trace elements (0.1-0.5%). This local quality approach ensures the fertilizer matches the specific requirements of degraded soil rather than using generic farmland fertilizers.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The patent modifies the chemical composition parameters of the fertilizer to optimize performance in engineering wound soil. By adjusting the ratios of organic matter, nitrogen, phosphorus, potassium, and trace elements, the fertilizer achieves better nutrient coordination and higher utilization rates in the target environment.

Inventive Principle:
Principle #35Parameter changes

2Ease of operation

If common microelement fertilizers are used, then the application is simple, but the effect of soil fertility and vegetation restoration is not obvious

Engineering Contradiction:
Improveease of applicationVSAvoideffectiveness of soil remediation
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The patent creates a composite fertilizer formulation combining multiple components: organic matter, nitrogen, phosphorus, potassium, and various trace elements (iron, manganese, zinc, copper, boron, molybdenum). This composite structure provides comprehensive nutrient supply that reliably promotes vegetation restoration in engineering wound soils.

Inventive Principle:
Principle #40Composite materials

3Productivity

If targeted organic complex microelement fertilizer is developed, then nutrient supply coordination and biological effectiveness are improved, but the production complexity increases

Engineering Contradiction:
Improvenutrient supply coordinationVSAvoidproduction process complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent divides the fertilizer formulation into distinct segments or components: organic matter base, macronutrients (N, P, K), and trace elements. Each segment can be prepared and mixed separately, allowing for systematic production while ensuring proper nutrient coordination in the final product.

Inventive Principle:
Principle #1Segmentation
