Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing industrial applications of microalgae are limited to a few species that are resistant to environmental changes and can be cultured in high-density conditions, lacking diversity and efficient nutrient production methods.
Innovation Solution
The development of novel microalgae from the Cyanidiophyceae family, including haploid and diploid forms, which are rich in nutrients such as amino acids and vitamins, and methods for culturing and transforming these algae to enhance nutrient production.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If microalgae are cultured outdoors in large quantities, then productivity and scalability are improved, but the requirement for environmental resistance and high-density growth capability increases, limiting species selection
Solution Approach 1:
The patent changes the environmental parameters by providing specific culture conditions (temperature 20-40°C, pH 2-6, light intensity 5000-20000 lux) that enable diverse Cyanidiophyceae species to thrive outdoors, resolving the contradiction between productivity and species versatility
Solution Approach 2:
The patent segments the microalgae culture system into specific operational phases (growth phase, harvesting phase, nutrient supplementation phase) with optimized parameters for each, allowing diverse species to be cultured efficiently at scale
2Reliability
If microalgae species resistant to environmental changes are selected for outdoor cultivation, then reliability and stability are improved, but nutrient composition diversity and extraction efficiency are limited
Solution Approach 1:
The patent identifies Cyanidiophyceae as a universal algal group that simultaneously provides environmental resistance for outdoor cultivation and rich nutrient composition (amino acids, vitamins, pigments), eliminating the trade-off between reliability and nutrient diversity
Solution Approach 2:
The patent optimizes culture parameters (temperature, pH, light, nutrients) to maximize the production of specific nutrients (astaxanthin, beta-carotene, amino acids) within the Cyanidiophyceae group, achieving both stability and high nutrient content
3Productivity
If high-density culture conditions are implemented, then productivity is improved, but the complexity of maintaining optimal growth conditions increases
Solution Approach 1:
The patent employs self-service mechanisms including natural sunlight for illumination, ambient temperature for heating, and spontaneous CO2 absorption from air, eliminating the need for complex artificial culture systems while achieving high-density growth
Solution Approach 2:
The patent defines specific parameter ranges (pH 2-6, temperature 20-40°C) that simplify culture system design by allowing broad operational windows that maintain high productivity without precise control mechanisms
