Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Malnutrition, particularly protein deficiency, remains a significant global issue due to imbalanced exploitation of marine resources, leading to nutritional deficiencies and health problems, including cardiovascular and metabolic disorders, exacerbated by the over-exploitation of high-protein fish species, which threatens their sustainability.
Innovation Solution
A method for deriving a high-quality protein powder from a diverse range of fish species, including non-commercial ones, using a process that involves obtaining raw fish material, verifying its quality, grinding and mixing with solvents, baking, filtration, oil separation, and dehydration to produce a protein powder with 85% protein concentration, complete amino gram, and minimal environmental impact.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If high-protein fish species are over-exploited to meet protein demand, then protein supply increases, but fish species sustainability deteriorates
Solution Approach 1:
The patent applies universality by developing a protein extraction method that can process multiple types of fish species (both commercial and non-commercial) through a single integrated system. The method uses universal solvents and standardized processing steps that work across diverse fish types, allowing the system to utilize underexploited species while maintaining protein quality standards.
Solution Approach 2:
The patent implements discarding and recovering by converting non-commercial fish species and fish by-products (which would otherwise be discarded) into valuable protein powder. The process recovers protein from materials that have low or no commercial value, thereby reducing pressure on commercially valuable fish species while meeting protein demand.
2Ease of manufacture
If conventional protein extraction methods are used, then processing is simpler, but protein quality and concentration deteriorate
Solution Approach 1:
The patent applies segmentation by dividing the protein extraction process into distinct sequential stages: initial solvent extraction, filtration, concentration, and drying. Each stage targets specific components and progressively purifies the protein, with the solvent-to-fish ratio and processing parameters optimized at each step to maintain simplicity while achieving high protein concentration (85-90%).
Solution Approach 2:
The patent implements parameter changes by systematically adjusting key process variables including solvent-to-fish material ratio (2:4), temperature, pressure, and solvent composition across different extraction stages. These controlled parameter changes enable high protein concentration and quality while maintaining a relatively simple overall process structure that can be implemented with standard equipment.
3Quantity of substance
If marine resources are exploited intensively to address malnutrition, then protein availability improves, but environmental balance deteriorates
Solution Approach 1:
The patent applies self-service by creating a system that utilizes underutilized marine resources (non-commercial fish species) to meet protein needs, thereby allowing commercially valuable species to sustain themselves and maintain ecological balance. The method enables the system to serve protein production needs through alternative, low-impact sources.
Solution Approach 2:
The patent implements discarding and recovering by transforming non-commercial fish species and fish processing by-products into valuable protein powder. This approach recovers nutritional value from materials that would otherwise be discarded or require intensive fishing of valuable species, thereby reducing environmental impact while improving protein availability.

AI summary
A method for deriving a protein powder from fish is presented. The method includes obtaining raw fish material and verifying the quality of the fish material. Solvents and concentrates are prepared and ground with the fish material to produce a mixture. The mixture placed in a reactor and baked. A first filtration of the mixture extracts solvents, concentrates, oil and water to produce a meal. The oil and water are separated to produce Omega 3 fish oil and water. The water is purified to produce purified water and the purified water is stored or bottled. A second filtration on the meal further extracts solvents and concentrates. The meal is ground to yield a fine texture and cured to produce the protein powder.
