Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If chemical synthesis is used to produce cannabinoids, then production can be performed without plant cultivation restrictions, but yields are low and costs are high
Solution Approach 1:
The patent uses engineered microorganisms as intermediary biosynthetic factories that convert readily available fatty acid substrates into cannabinoids through heterologously expressed enzyme pathways, eliminating the need for plant cultivation while achieving high yields through biological amplification
Solution Approach 2:
The patent optimizes multiple parameters including enzyme expression levels, pathway flux distribution, substrate availability, and cellular metabolism to maximize cannabinoid production efficiency in the engineered host organisms
2Productivity
If traditional plant-based methods are used to produce cannabinoids, then production is more efficient and cost-effective, but cultivation is restricted in many jurisdictions
Solution Approach 1:
The patent uses engineered microorganisms as intermediary biosynthetic factories that convert readily available fatty acid substrates into cannabinoids through heterologously expressed enzyme pathways, eliminating the need for plant cultivation while achieving high yields through biological amplification
Solution Approach 2:
The patent copies the cannabinoid biosynthetic pathway from Cannabis plants into heterologous host organisms, transferring the genetic instructions for key enzymes to create functional biosynthetic systems in alternative hosts that are not subject to cultivation restrictions
3Adaptability or versatility
If chemical synthesis is used to produce cannabinoids, then production can be performed without plant cultivation restrictions, but costs are high
Solution Approach 1:
