Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional shrimp feed with soybean powder and fat-free soybean powder is used, then the feed is easy to manufacture, but the feed lacks essential nutrients leading to low survival rate and high mortality rate
Solution Approach 1:
The patent applies preliminary action by pre-fermenting soybean powder and fat-free soybean powder with specific microorganisms (aerobic bacteria, anaerobic bacteria, and facultative microorganisms) before feeding to shrimp. This pre-processing step enriches the feed with essential nutrients, vitamins, and amino acids, thereby improving survival rate and reducing mortality rate while maintaining ease of manufacture through a straightforward fermentation process.
2Stability of the object's composition
If conventional shrimp feed with soybean powder is used, then the manufacturing cost is low, but the water stability is poor leading to difficulty in controlling PH value, dissolved oxygen, and ammonia nitrogen
Solution Approach 1:
The patent applies parameter changes by transforming the chemical and biological parameters of the feed through fermentation. The fermented feed exhibits improved water stability, better pH buffering capacity, and enhanced ability to maintain dissolved oxygen levels. The fermentation process modifies the feed's composition to reduce ammonia nitrogen release, thereby improving water quality stability without significantly increasing manufacturing complexity.
3Productivity
If vegetable protein feed is used instead of animal protein source, then the manufacturing cost is reduced, but the feed conversion rate dramatically increases
Solution Approach 1:
The patent applies parameter changes by using fermentation to transform vegetable protein (soybean powder and fat-free soybean powder) into a nutritionally superior product. The fermentation process increases protein digestibility, generates essential amino acids, and produces growth-promoting substances, thereby improving feed conversion rate to be comparable with or better than animal protein feeds while maintaining lower manufacturing costs.
Solution Approach 2:
The patent uses microorganisms (aerobic bacteria, anaerobic bacteria, and facultative microorganisms) as intermediaries to convert inexpensive vegetable protein into a high-nutrition feed. These microorganisms act as biological catalysts that enrich the feed with essential nutrients, making vegetable protein feed as effective as animal protein feed in terms of feed conversion rate while maintaining cost advantages.

Function Achieved in This Case
The system achieves high survival rates, low mortality rates, and efficient feed conversion while maintaining water stability and reducing environmental impact through the use of easily implementable and cost-effective fermentation methods.
Implementation Method 1
a liquid-fermentation container which is an airtight container such that the soybean and fat-free soybean powder can be fermented under an anaerobic environment for obtaining the liquid-fermentation feed
Implementation Method 2
a solid-fermentation container which is good in permeability such that the soybean and fat-free soybean powder can be fermented under an aerobic environment for obtaining the solid-fermentation feed

AI summary
A shrimp aquaculture system includes the steps of: (1) preparing a water container; (2) exposing the water container under the sunlight, and then filling with predetermined amount of water; (3) adding 50 liter of liquid-fermentation feed into the water container at least 1 to 2 times per day; (4) adding 50 kilogram of beneficial agents into the water container once per day to obtain nursing water; (5) adding larva and young shrimp into the nursing water, and further adding a solid-fermentation feed into the nursing water, at least once a day, lasting for 0.5 to 3 months beginning on the date of adding young and larva shrimp; (6) three months later, adding regular shrimp feed containing beneficial agents into the water container; and (7) adding the amount of 1 to 3 ppm of photosynthetic bacteria into the nursing water of the water container once a day.
