Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If traditional solvent extraction methods are used, then the extraction process is simple to operate, but the extraction speed is slow and time-consuming
Solution Approach 1:
The patent applies parameter changes by transitioning from traditional solvent extraction to supercritical fluid extraction, changing the physical state and properties of the extraction medium. By operating at supercritical conditions (temperature above critical temperature and pressure above critical pressure), the system achieves significantly faster extraction speeds while reducing overall extraction time compared to conventional methods
Solution Approach 2:
The patent utilizes phase transitions of carbon dioxide between supercritical and gaseous states to enable rapid extraction and easy separation. The supercritical fluid penetrates the plant material efficiently, and upon pressure reduction, it transitions to gas phase, allowing quick separation of essential oils without prolonged processing time
2Productivity
If supercritical carbon dioxide extraction is used, then the extraction speed and efficiency are improved, but the system complexity increases
Solution Approach 1:
The patent applies universality by designing a integrated system where the supercritical fluid extraction vessel also serves as the extraction chamber, and the separation vessel handles both separation and collection functions. The control system manages multiple parameters (pressure, temperature, flow rate) through a single automated interface, reducing operational complexity despite the advanced extraction technology
Solution Approach 2:
The patent uses carbon dioxide as an intermediary substance that facilitates both extraction and separation processes. The supercritical CO2 acts as a mediator that can penetrate plant materials effectively during extraction, then easily separates from essential oils during the separation phase, enabling high productivity without requiring complex multiple-stage processing systems
3Stability of the object's composition
If constant flow rate control is implemented, then the extraction consistency is improved, but the control system complexity increases
Solution Approach 1:
The patent implements feedback control by using flow sensors to continuously monitor the supercritical fluid flow rate and automatically adjusting system parameters to maintain constant flow. The control system receives real-time data on extraction progress and modifies pressure or temperature settings to ensure consistent extraction conditions throughout the process, achieving high extraction consistency through automated feedback mechanisms
