Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If palm oil production is increased to meet global demand, then the supply of vegetable oil is improved, but environmental harm increases due to tropical deforestation and habitat destruction
Solution Approach 1:
The patent extracts the oil production function from traditional plant-based systems (palm oil) and relocates it to microbial systems (oleaginous microorganisms). This extraction allows the beneficial oil production capability to be separated from the harmful environmental impacts associated with palm oil plantations, enabling sustainable alternative production
Solution Approach 2:
The patent creates a copy of palm oil's functional properties (high saturated fat content, stability, versatility) using microbially produced oils from oleaginous microorganisms. These microbial oils replicate the desirable characteristics of palm oil while avoiding the environmental degradation associated with its production
2Productivity
If palm oil plantations are expanded to meet increasing demand, then the availability of vegetable oil is improved, but habitat destruction and biodiversity loss worsen
Solution Approach 1:
The patent employs oleaginous microorganisms that can self-replicate and self-produce oils through fermentation processes. These microorganisms serve themselves by converting sugars and carbon sources into lipid accumulations, eliminating the need for land expansion and associated habitat destruction while maintaining high productivity
Solution Approach 2:
The patent fundamentally changes the production parameter from agricultural land-based systems to microbial fermentation systems. This parameter change enables oil production in controlled bioreactors without requiring tropical forest conversion, thereby maintaining productivity while eliminating habitat destruction
3Object-affected harmful factors
If palm oil is used as a sustainable alternative, then the need for tropical deforestation is reduced, but the availability of sustainable oil supply must be increased
Solution Approach 1:
The patent creates microbial oils with universal applicability across multiple industries (food, cosmetics, biofuels, soaps) similar to palm oil's versatility. The oleaginous microorganisms can be engineered to produce oils with various fatty acid profiles, making the sustainable supply adaptable to different application requirements while reducing deforestation
4Stability of the object's composition
If microbial oils are produced with high saturated fat content, then the stability and shelf life are improved, but the production complexity increases
Solution Approach 1:
The patent controls the fatty acid composition parameters of microbial oils through fermentation conditions and strain selection to achieve high saturated fat content (35-85%). This parameter control enables production of stable oils with extended shelf life while managing production complexity through standardized fermentation processes and selective breeding of oleaginous strains
