Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If a capacitor is used to store electrical energy, then the energy storage capacity is improved, but the discharge rate is too rapid and does not match the energy rate requirement of the device
Solution Approach 1:
The patent introduces a transformer as an intermediary device between the capacitor and the motor. The transformer's impedance characteristics act as a mediator to control the discharge rate, preventing immediate discharge while still allowing energy transfer to the motor over a prolonged period.
Solution Approach 2:
The patent changes the electrical parameters of the system by using a transformer with specific impedance characteristics. This alters the discharge behavior of the capacitor from rapid to controlled, matching the energy rate requirements of the motor while maintaining high energy storage capacity.
2Use of energy by moving object
If a capacitor discharges energy, then the stored energy is delivered, but the voltage declines making it unsuitable for prolonged operation
Solution Approach 1:
The transformer serves as an intermediary that buffers the voltage decline of the capacitor. It maintains a more stable voltage output to the motor even as the capacitor voltage decreases, thereby extending the operational duration.
Solution Approach 2:
The patent employs a dynamically adjustable transformer with variable turns ratio that can adapt to changing voltage conditions. As the capacitor voltage declines, the transformer ratio can be adjusted to maintain optimal voltage delivery to the motor, extending operational duration.
3Quantity of substance
If a capacitor is used to drive an electrical motor, then the energy storage is sufficient, but the voltage mismatch prevents prolonged motor operation
Solution Approach 1:
The patent uses a transformer with variable turns ratio to dynamically adjust the voltage parameters. This allows the system to maintain voltage matching between the capacitor source and the motor load throughout the discharge process, enabling prolonged operation while utilizing the full energy storage capacity.
Solution Approach 2:
The dynamically adjustable transformer allows the system to adapt to changing voltage conditions during capacitor discharge. By continuously or periodically adjusting the turns ratio, the system maintains optimal voltage matching for motor operation throughout the entire energy discharge cycle.
