Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If vegetable oil composition is processed using conventional methods, then commodity-grade products like biodiesel feedstock or animal feed are produced, but the product versatility and value are limited
Solution Approach 1:
The patent applies parameter changes by modifying the chemical composition of vegetable oil through controlled oxidation processes. By adjusting oxidation parameters (ozone concentration, treatment time, temperature), the vegetable oil is transformed into compositions with different functional properties - from conventional biodiesel feedstock to antimicrobial and virucidal disinfectant compositions, thereby achieving product versatility without fundamentally changing the processing infrastructure.
Solution Approach 2:
The invention creates multi-functionality by producing a single vegetable oil-based composition that serves multiple purposes: it can be used as biodiesel feedstock, animal feed ingredient, antimicrobial agent, and virucidal disinfectant. This is achieved by controlling the oxidation degree and composition to provide both fuel properties and biocidal activities, eliminating the need for separate processing lines for different product types.
2Reliability
If vegetable oil is treated with ozone to form ozonide compounds, then antimicrobial and virucidal properties are generated, but the process requires precise control of reaction conditions
Solution Approach 1:
The patent employs parameter changes by systematically varying oxidation parameters (ozone dose, contact time, temperature, pH) to achieve reliable antimicrobial and virucidal efficacy. By establishing optimal parameter ranges and controlling the progression from ozonide formation to decomposition, the process ensures consistent biocidal activity while maintaining manageable process complexity through standardized control protocols.
Solution Approach 2:
The invention replaces complex mechanical separation and purification systems with a chemical transformation approach. Instead of mechanically separating active ingredients from vegetable oil through complex filtration or extraction systems, the process uses controlled oxidation to chemically generate the active antimicrobial and virucidal compounds directly in the oil matrix, simplifying the overall process equipment requirements.
3Quantity of substance
If ozonide compounds are decomposed by heat treatment, then carboxylic acids are formed for antimicrobial activity, but energy input is required
Solution Approach 1:
The patent applies parameter changes by optimizing heat treatment parameters (temperature, time, atmosphere) to efficiently decompose ozonide compounds into carboxylic acids with antimicrobial activity. By controlling the thermal decomposition process to occur at moderate temperatures and extended times, or alternatively at higher temperatures for shorter durations, the process achieves high carboxylic acid concentration while managing energy input through process integration with existing biorefinery thermal systems.
