Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If conventional multiple and large-scale fertilization is used, then the nutritional demands of rice throughout its reproductive period can be met, but rice quality decreases, ecological pollution increases, soil acidification worsens, biodiversity is compromised, and production costs increase
Solution Approach 1:
The patent applies preliminary action by using soil conditioners to improve soil fertility and structure before fertilization, enabling the soil to release nutrients more efficiently and reduce the need for large-scale fertilizer application. The soil conditioner is applied in advance to create a favorable soil environment that minimizes pollution while meeting crop nutritional needs.
Solution Approach 2:
The patent changes the parameters of fertilizer application by transitioning from conventional large-scale fertilization to reduced fertilization combined with soil conditioner application. This parameter change involves adjusting the dosage, timing, and method of fertilizer application to achieve both pollution reduction and adequate nutrient supply.
2Reliability
If pre-made controlled-release fertilizers and soil conditioners are used, then fertilizer utilization rate increases and pollution reduces, but farmers cannot customize formulas based on specific conditions, leading to increased costs and reduced adaptability
Solution Approach 1:
The patent applies segmentation by dividing the fertilizer system into separate controllable components: soil conditioner, controlled-release nitrogen fertilizer, and quick-acting nitrogen fertilizer. This segmentation allows farmers to adjust the dosage and combination of each component based on their specific field conditions, achieving both high utilization rate and customization capability.
Solution Approach 2:
The patent applies dynamics by enabling flexible and adjustable fertilizer formulations that can be customized according to different soil types, crop stages, and environmental conditions. The system transitions from fixed pre-made products to a dynamic formulation approach where farmers can optimize the combination of soil conditioner and different fertilizer types for their specific needs.
3Object-affected harmful factors
If high dosage of controlled-release fertilizer is applied to achieve precise fertilizer reduction, then environmental pollution decreases, but production costs increase due to the high cost of existing controlled-release fertilizers
Solution Approach 1:
The patent applies merging by combining soil conditioner with controlled-release nitrogen fertilizer and quick-acting nitrogen fertilizer into an integrated fertilization system. This combination allows the soil conditioner to enhance nutrient retention and release, reducing the overall dosage of expensive controlled-release fertilizer needed while maintaining environmental benefits and lowering production costs.
Solution Approach 2:
The patent applies composite materials by creating a composite fertilization approach that integrates organic soil conditioner with inorganic controlled-release and quick-acting fertilizers. This composite system leverages the advantages of each material type to achieve pollution reduction at lower cost than using high dosages of controlled-release fertilizer alone.
