Solution Overview
Problem
Existing vegetable oils treated with electric discharges have unpredictable and uncontrollable physico-chemical properties, making it difficult to maintain viscosity and stability, especially in applications like cosmetics and motor oils, where controlled viscosity is crucial for performance and safety.
Innovation Solution
A vegetable oil with a dynamic viscosity of 1900 mPa.s or greater and a relaxation time of 200 s or less, measured using a cone-plane viscometer, is achieved through specific plasma treatment parameters, such as frequency and time, ensuring reproducible and controllable properties.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If vegetable oil is treated by electric discharges to increase viscosity, then the oil can maintain lubrication film at high temperatures, but the physico-chemical properties become unpredictable and uncontrollable
Solution Approach 1:
The patent applies parameter changes by systematically varying electric discharge treatment parameters (power, time, frequency) to achieve controlled viscosity modification. By establishing specific parameter ranges and treatment durations, the process transforms unpredictable chemical modifications into a controllable method for achieving target viscosity values while maintaining reproducibility
Solution Approach 2:
The patent implements feedback control through continuous monitoring and measurement of viscosity during and after electric discharge treatment. By measuring viscosity at different treatment stages and adjusting subsequent treatment parameters based on these measurements, the process achieves precise control over the final physico-chemical properties of the modified oil
2Reliability
If vegetable oil viscosity is increased through electric discharge treatment, then lubrication performance improves, but the treatment process becomes complex and difficult to reproduce
Solution Approach 1:
The patent simplifies the treatment process by identifying and controlling only the critical parameters (power, time, frequency) that significantly affect viscosity modification. By focusing on these key parameters and establishing their optimal ranges, the complex electric discharge process becomes reproducible and easier to implement without requiring control of all possible variables
Solution Approach 2:
The patent applies preliminary action by conducting systematic preliminary experiments to establish the relationship between treatment parameters and viscosity outcomes. These preliminary studies create a foundation of known parameter ranges and treatment conditions that guide subsequent practical applications, reducing the complexity of the overall process by pre-determining optimal settings
3Manufacturing precision
If mineral oil is used as base oil, then viscosity can be adjusted, but toxic aromatic hydrocarbons are present
Solution Approach 1:
The patent applies parameter changes by systematically varying electric discharge treatment parameters (power, time, frequency) to achieve controlled viscosity modification. By establishing specific parameter ranges and treatment durations, the process transforms unpredictable chemical modifications into a controllable method for achieving target viscosity values while maintaining reproducibility
Solution Approach 2:
The patent converts the typically harmful effect of electric discharge (uncontrolled chemical modification) into a beneficial process for viscosity enhancement. By carefully controlling the discharge parameters, the energy that would otherwise cause random degradation is directed toward controlled polymerization and viscosity improvement, transforming a potential harm into a useful modification
