Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If mechanical adjustment of capacitor plates is used to vary electromagnetic field power, then field emission power can be regulated, but response time is long and instantaneous temperature adaptation is not achieved
Solution Approach 1:
The patent replaces the mechanical adjustment system (capacitor plates) with an electronic control system. The oscillator circuit electronically varies the electromagnetic field emission power by controlling the voltage applied to the electrodes, eliminating mechanical movement and achieving instantaneous response. The electronic control circuit adjusts the power level by modifying the voltage signal fed to the electrodes, providing rapid adaptation without mechanical delays.
Solution Approach 2:
The patent changes the operating parameters of the electromagnetic field generation system from mechanical (plate distance) to electrical (voltage amplitude and frequency). By varying the voltage parameters applied to the electrodes through electronic control, the system achieves rapid adjustment of field emission power. This parameter transformation enables instantaneous response time while maintaining effective power regulation.
2Power
If mechanical plates are used for power adjustment, then field emission can be controlled, but safety is reduced due to risk of unexpected electric discharges
Solution Approach 1:
The patent eliminates the mechanical capacitor plate system that poses safety risks from electric discharges. Instead, it uses an electronic control circuit that safely regulates power by controlling the voltage signal to the electrodes. The electronic system provides precise control without the high-voltage exposure risks associated with mechanical plate adjustment, thereby improving safety and reliability.
Solution Approach 2:
The patent introduces an electronic control circuit as an intermediary between the power source and the electrodes. This intermediary circuit safely manages the voltage and power delivery, preventing direct exposure to high voltages that could cause electric discharges. The control circuit acts as a protective mediator, regulating power while maintaining safety through electronic rather than direct mechanical/electrical connection methods.
3Loss of time
If electronic control circuits are used for instantaneous variation of electrical parameters, then response time is reduced, but device complexity increases
Solution Approach 1:
The patent designs the electronic control circuit to perform multiple functions: it generates the voltage signal, regulates the power level, controls the frequency, and protects against electric discharges. By consolidating these functions into a single integrated electronic control system, the patent achieves instantaneous response time without proportionally increasing overall device complexity. The multi-functional design optimizes the complexity-performance ratio.
Solution Approach 2:
The electronic control circuit is designed to automatically adjust electrical parameters in response to control signals without requiring manual intervention. The system self-regulates the voltage and power levels, providing instantaneous adaptation to desired operating conditions. This self-service capability reduces the need for complex external control mechanisms while achieving rapid response times.
