Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional fertilizers often result in environmental pollution and toxicity to crops, and existing organic alternatives lack sufficient nitrogen, oligosaccharides, and carboxylic acids, failing to provide adequate macro and micro-elements for plant nutrition, especially for sensitive crops like coffee.
Innovation Solution
A novel foliar fertilizer composition obtained through sequential enzymatic hydrolysis of soybean paste using a proteolytic enzyme with a cysteine bioactive site and cellulase from Trichoderma harzianum, resulting in a high-nitrogen, oligosaccharide-rich formulation that does not require synthetic substances.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If chemical fertilizers are used to provide nutrients, then plant growth is improved, but environmental pollution and crop toxicity increase
Solution Approach 1:
The patent changes the chemical composition parameters of fertilizers by using enzymatic hydrolysis to convert complex organic materials into simpler, bioavailable forms. This includes generating free amino acids, oligosaccharides, and carboxylic acids with specific molecular weights, thereby providing nutrients in forms that are effective for plant absorption without the toxic side effects of synthetic chemicals
Solution Approach 2:
The patent uses readily available organic waste materials such as soybean paste, agricultural residues, and manure as fertilizer substrates. These inexpensive, biodegradable materials are converted through enzymatic hydrolysis into effective nutrients, replacing persistent synthetic fertilizers with short-lived, naturally decomposable organic matter that enriches soil without long-term pollution
2Object-affected harmful factors
If organic hydrolysates are used as fertilizer substitutes, then phytotoxicity is reduced, but nitrogen content and nutritional potency decrease
Solution Approach 1:
The patent applies preliminary enzymatic hydrolysis treatment to organic substrates before application to plants. By pre-digesting complex organic materials with specific enzymes (proteases, cellulases, hemicellulases) under controlled conditions, the system converts indigestible or low-nutrition materials into bioavailable forms rich in free amino acids, oligosaccharides, and carboxylic acids, thereby enhancing nutritional potency while maintaining low phytotoxicity
Solution Approach 2:
The patent creates composite fertilizer compositions that combine multiple hydrolyzed organic materials with complementary nutritional profiles. By blending hydrolysates from different sources (soybean paste, agricultural residues, manure) and supplementing with trace elements, the system achieves a balanced nutrient composition that provides comprehensive nutrition (NPK plus micronutrients) while maintaining biocompatibility and low phytotoxicity
3Device complexity
If single enzymatic hydrolysis is used to produce fertilizer, then production complexity is reduced, but bioavailability and nutritional power decrease
Solution Approach 1:
The patent segments the hydrolysis process into multiple sequential enzymatic stages, each targeting specific components of the organic substrate. First, proteases break down proteins into peptides and amino acids; then cellulases and hemicellulases decompose cellulose and hemicellulose into oligosaccharides; finally, additional hydrolysis releases carboxylic acids. This segmented approach ensures complete degradation of complex molecules into bioavailable forms without requiring overly complex equipment
Solution Approach 2:
The patent uses specific enzymes as intermediary catalysts to facilitate the conversion of complex organic materials into bioavailable nutrients. By introducing proteases, cellulases, and hemicellulases as biological mediators, the system achieves efficient and selective hydrolysis under mild conditions, thereby enhancing the reliability and bioavailability of the resulting fertilizer without requiring extreme temperatures or pressures that would increase process complexity
4Stability of the object's composition
If denatured soybean particles are used in fertilizer, then particle stability is improved, but free amino acids and oligosaccharides are eliminated
Solution Approach 1:
Instead of denaturing soybean particles to improve stability (which destroys nutrients), the patent inverts the approach by using fresh or minimally processed soybean paste as substrate and applying enzymatic hydrolysis to generate free amino acids and oligosaccharides. The resulting hydrolysate provides both stability through standardized composition and high nutritional value through the presence of bioactive molecules, achieving the opposite of the conventional denaturation approach
