Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional delivery systems (oils, capsules, sprays) are used for therapeutic agents, then ease of administration is improved, but stability and bioavailability deteriorate due to impurities and variable purity profiles
Solution Approach 1:
The patent transforms the physical and chemical parameters of therapeutic agents by converting them into lipid-based particle formulations. This changes the delivery system from conventional oils and capsules to standardized particles with controlled size, composition, and surface properties, thereby improving stability and bioavailability while maintaining ease of administration
Solution Approach 2:
The patent creates composite lipid-based particle systems that combine therapeutic agents with lipid materials (phospholipids, triglycerides, sterols). This composite structure provides both the stability of lipid materials and the therapeutic efficacy of the active agents, resolving the contradiction between reliability and ease of operation
2Reliability
If high-purity therapeutic agents are used, then reliability of delivery is improved, but manufacturing complexity increases due to purification requirements
Solution Approach 1:
The patent segments the manufacturing process into distinct stages: first incorporating therapeutic agents into lipid particles, then purifying the particles separately. This segmentation allows purification to occur at a stage where particles are already formed, simplifying the overall process compared to purifying crude extracts before formulation
Solution Approach 2:
The lipid-based particles serve as an intermediary carrier that facilitates the separation and purification of therapeutic agents. The particles act as a medium through which impurities can be removed while maintaining the integrity and concentration of the active therapeutic compounds, thereby achieving high purity without excessive manufacturing complexity
3Reliability
If lipid-based particle compositions are formulated, then bioavailability and stability are improved, but device complexity increases due to formulation requirements
Solution Approach 1:
The patent develops universal lipid-based particle formulations that can accommodate multiple different therapeutic agents (cannabinoids, terpenes, flavonoids, peptides, proteins) within a single platform. This multi-functional approach reduces formulation complexity by providing a standardized system that works across different drug types, rather than requiring separate formulations for each agent
Solution Approach 2:
The patent controls and standardizes key parameters of the lipid particles (size, composition, surface charge) to create a reproducible formulation system. By fixing these critical parameters within specific ranges, the formulation process becomes more predictable and less complex, while still achieving improved bioavailability and stability
4Ease of manufacture
If conventional extraction methods are used, then ease of manufacture is improved, but purity and consistency deteriorate due to impurities
Solution Approach 1:
The patent selectively extracts therapeutic agents from plant material using lipid-based solvents and particle formation processes. This extraction method specifically isolates the desired compounds (cannabinoids, terpenes, flavonoids) while leaving behind unwanted impurities (chlorophyll, waxes, plant debris), thereby achieving high purity and consistency while maintaining manufacturing efficiency
Solution Approach 2:
The patent uses composite lipid extraction systems that combine multiple lipid materials (phospholipids, triglycerides, sterols) to enhance the selectivity and efficiency of the extraction process. This composite approach improves both the ease of manufacture and the purity of the extracted therapeutic agents by leveraging the complementary properties of different lipid materials
