Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If wet fractionation is used to separate trichomes from plant biomass, then separation can be achieved via differences in specific gravity, but valuable aromatic compounds are lost in the ice water and additional drying steps are required to prevent fungal propagation
Solution Approach 1:
The patent replaces the wet mechanical separation system with an electrostatic separation system. Instead of using ice water extraction and physical agitation, the invention uses electrostatic forces to separate trichomes from plant biomass, eliminating the need for water contact and subsequent drying steps, thereby preventing aromatic compound loss.
Solution Approach 2:
The patent changes the separation parameter from specific gravity (wet fractionation) to electrical charge properties (electrostatic separation). By utilizing the natural electrostatic properties of trichomes versus plant biomass, the system achieves separation without water contact, avoiding compound degradation.
2Quantity of substance
If dry fractionation is used to separate trichomes from plant biomass, then separation can be achieved via density differences, but the process is extremely sensitive to operating parameters and requires additional purification steps to achieve high product purity
Solution Approach 1:
The patent replaces the complex mechanical dry fractionation system with an electrostatic separation system. Instead of tumbling, sieving, and centrifuging with precise control of temperature and humidity, the invention uses electrostatic forces that are inherently more stable and less sensitive to environmental variations, reducing process complexity.
Solution Approach 2:
The patent changes the separation mechanism from density-based mechanical separation to charge-based electrostatic separation. This parameter change makes the process less sensitive to operating conditions like temperature and humidity, and eliminates the need for multiple purification steps.
3Manufacturing precision
If static tech is used to purify trichomes from contaminants, then electrostatic charging can be achieved on dried plant biomass, but the process is very labor-intensive and not scalable
Solution Approach 1:
The patent implements a self-service electrostatic separation system where the plant biomass and trichomes automatically acquire triboelectric charges as they pass through the system, eliminating the need for manual charging operations. The system performs both charging and separation in one automated process, enabling scalability.
Solution Approach 2:
The patent replaces the manual static tech process with an automated electrostatic separation system. Instead of hand-charging biomass on nylon screens and collecting with vinyl gloves, the invention uses a controlled electrostatic field to automatically separate charged trichomes from plant biomass, dramatically increasing throughput and scalability.
