Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If high-frequency fluctuating magnetic field is generated at the stator to produce induction current, then the motor can rotate, but the power consumption increases and efficiency decreases
Solution Approach 1:
The patent replaces the traditional electromagnetic induction mechanism with a capacitive-electric field mechanism. Instead of using high-frequency fluctuating magnetic fields to generate induction current, the invention uses capacitive structures to store and release electrical energy, creating strong electric fields that directly act on charges in the rotor. This substitution of the fundamental physical mechanism eliminates the need for high-frequency magnetic field generation, thereby reducing power consumption while maintaining motor output capability
Solution Approach 2:
The patent fundamentally changes the operating parameter from magnetic field frequency to electric field strength. By using capacitive structures charged to high voltages (e.g., tens of kilovolts), the system generates intense electric fields without requiring high-frequency oscillation. This parameter change from frequency-dependent magnetic fields to voltage-dependent electric fields directly addresses the power consumption issue, as electric field generation is more energy-efficient at the required power levels
2Speed
If high-frequency fluctuating magnetic field is used to generate induction current, then the motor operates, but the rotational speed is limited
Solution Approach 1:
The patent replaces the magnetic field-based speed limitation with an electric field-based system. In traditional motors, rotational speed is constrained by the frequency of the magnetic field oscillation. By substituting this with a capacitive system that uses direct charging and discharging of capacitors, the motor can achieve much higher speeds since the electric field can be established and collapsed almost instantaneously,不受限于磁频振荡频率的约束
Solution Approach 2:
The patent employs periodic charging and discharging of the capacitive structures to create alternating electric fields that drive the rotor. This periodic action occurs at much higher frequencies than magnetic field oscillation can achieve, enabling the motor to operate at higher rotational speeds. The capacitive switching can occur in microseconds or nanoseconds, compared to the millisecond-scale magnetic field cycles in traditional motors
3Ease of operation
If traditional electromagnetic induction is used, then the motor generates rotation, but the controllability is reduced
Solution Approach 1:
The patent incorporates feedback control mechanisms that monitor the motor's operational state and adjust the capacitive charging/discharging parameters accordingly. By measuring rotor position, speed, and load conditions, the control system optimizes the voltage and timing of capacitive discharge to the rotor windings, achieving precise control over motor output. This feedback capability enables independent control of multiple parameters (voltage, frequency, phase) without the energy losses associated with traditional magnetic field control
Solution Approach 2:
The patent employs dynamic control of the capacitive structures, where the charging voltage, discharge timing, and capacitance values can be rapidly adjusted based on real-time operational requirements. This dynamic adaptability allows the motor to respond quickly to control signals and maintain optimal efficiency across varying load conditions, unlike traditional motors where magnetic field parameters are more difficult to modify dynamically
