Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If high voltage is applied at extremely low frequency to generate plasma, then plasma with great electronic energy is generated, but gas reactive material is ionized or dissociated instead of vibrational excitation, reducing product gas yield and energy efficiency
Solution Approach 1:
The patent applies parameter changes by adjusting the frequency of high voltage applied to the plasma generation electrodes. Specifically, the frequency is set within a predetermined range (e.g., 1 kHz to 1 MHz) to control the electronic energy of plasma, thereby promoting vibrational excitation rather than ionization or dissociation of gas reactive materials. This optimization of the frequency parameter resolves the contradiction between energy efficiency and product gas yield.
2Productivity
If high voltage frequency is set extremely high to increase plasma generation frequency, then electron density becomes excessive, but power consumption increases, reducing energy efficiency
Solution Approach 1:
The patent optimizes the frequency parameter of high voltage applied to plasma generation electrodes, setting it within a predetermined range (e.g., 1 kHz to 1 MHz) to achieve appropriate electron density and electronic energy levels. This prevents excessive power consumption while maintaining effective plasma generation frequency, thereby resolving the contradiction between productivity and energy efficiency.
3Productivity
If catalyst reaction field is set to extremely high temperature to increase product gas yield, then great thermal energy must be inputted, but energy efficiency is low and production cost is high
Solution Approach 1:
The patent replaces thermal energy input with plasma energy input by applying high voltage to generate plasma in the catalyst reaction field. The plasma provides electronic energy that promotes vibrational excitation of gas reactive materials at lower temperatures, thereby resolving the contradiction between product gas yield and energy efficiency by substituting the thermal mechanism with a plasma-based mechanism.
Solution Approach 2:
The patent changes the energy input parameter from thermal energy to plasma electronic energy by applying high voltage within a predetermined frequency range. This parameter change enables the system to achieve effective gas reactive material activation without requiring extremely high temperatures, thus resolving the contradiction between productivity and energy efficiency.
