Solution Overview
Problem
Existing methods for controlling chemical reactions involving liquid phases either completely prevent or guarantee cavitation, making it difficult to access metastable compounds with good yields.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If cavitation is completely prevented in liquid phase reactions, then reaction reliability is improved, but access to metastable compounds is lost
Solution Approach 1:
The patent applies dynamic control of pressure parameters, continuously adjusting the pressure minimum during the reaction process to maintain it between 90-105% of the cavitation pressure. This dynamic approach allows the system to operate in a metastable regime where cavitation is suppressed but its effects are enhanced, enabling access to metastable compounds while maintaining reaction reliability.
Solution Approach 2:
The invention changes the pressure parameter from a static prevention approach to a dynamic control approach, maintaining pressure minimum at a specific percentage (90-105%) of the cavitation pressure rather than completely preventing pressure drops. This parameter change enables the system to exploit near-cavitation effects for producing metastable compounds while avoiding actual cavitation damage.
2Productivity
If cavitation is guaranteed in liquid phase reactions, then kinetic control is improved, but reaction reliability deteriorates
Solution Approach 1:
The patent applies partial action by maintaining pressure minimum at 90-105% of cavitation pressure, which is close to but does not fully reach the cavitation point. This partial approach provides sufficient kinetic control enhancement through near-cavitation effects while avoiding the reliability deterioration caused by full cavitation. The system gets 90-105% of the kinetic control benefit with minimal cavitation occurrence.
3Productivity
If pressure minimum is set at 105% of cavitation pressure, then kinetic control is improved, but cavitation risk increases
Solution Approach 1:
The patent implements feedback control by continuously monitoring the pressure minimum and adjusting it to maintain a specific relationship (90-105%) with the cavitation pressure. This feedback mechanism ensures that the system operates optimally for kinetic control while automatically preventing excessive pressure drops that would cause harmful cavitation. The feedback loop balances productivity improvement with harm prevention.
