Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional spark ignition systems are used, then the ignition system is simple and reliable, but fuel combustion efficiency is low and unburned fuel remains in the combustion chamber
Solution Approach 1:
The patent replaces the conventional mechanical/electrical spark ignition system with a radio frequency (RF) electromagnetic field-based plasma ignition system. The RF radiation device generates high-energy plasma discharges through electromagnetic radiation, substituting the traditional spark plug mechanism with a non-contact electromagnetic field approach that achieves more complete fuel combustion.
Solution Approach 2:
The patent changes the energy parameters of the ignition system by using high-power RF electromagnetic fields (typically in the range of millions of volts per meter) instead of conventional low-energy sparks. This parameter change enables the creation of extended plasma channels that propagate through the combustion chamber, ensuring complete combustion of the fuel-air mixture even under high compression conditions.
2Object-affected harmful factors
If conventional spark ignition is used, then the system is simple to operate, but harmful emissions such as NOx, CO2, and CO are produced
Solution Approach 1:
The patent replaces the conventional spark ignition mechanism with an RF electromagnetic field-based plasma generation system. This substitution enables more complete combustion of the fuel-air mixture, thereby reducing the formation of harmful emissions such as nitrogen oxides (NOx), carbon dioxide (CO2), and carbon monoxide (CO) that result from incomplete combustion in traditional systems.
Solution Approach 2:
The patent applies high-power RF electromagnetic fields to generate plasma discharges with sufficient energy to ensure complete combustion of the fuel-air mixture. By changing the energy parameters from conventional low-energy sparks to high-energy RF plasma, the system achieves more thorough combustion, thereby reducing harmful emissions while accepting increased system complexity.
