Engineering Contradiction Analysis
1Reliability
If conventional processing mechanisms are used to suppress current-spike, then the spike current can be suppressed, but additional control circuits or high-cost circuitry elements are required, leading to complex control mechanisms
Solution Approach 1:
The patent introduces an inductive reactance element as an intermediary component between the switched capacitor circuit and the load. This inductive element generates an induced voltage that opposes the spike current, effectively suppressing the current spike without requiring complex control circuits. The inductive reactance element acts as a mediator that passively counteracts the harmful spike current through electromagnetic induction principles
Solution Approach 2:
The inductive reactance element automatically generates the opposing induced voltage in response to spike current without requiring external control signals or complex control mechanisms. The element serves itself by utilizing the spike current's own magnetic field changes to generate the counter-voltage, eliminating the need for additional control circuits

If conventional processing mechanisms are used to suppress current-spike, then the spike current can be suppressed, but high-cost circuitry elements and additional control circuits are required
Solution Approach 1:
The patent employs a simple inductive reactance element that can be implemented using basic inductor components or even parasitic inductance from existing circuit traces. This approach replaces expensive specialized spike suppression circuitry with a simple, inexpensive inductive element that provides effective suppression without requiring high-cost circuitry elements
Solution Approach 2:
By introducing the inductive reactance element as a passive intermediary component, the patent avoids the need for expensive active control circuits. The inductive element provides a cost-effective solution that suppresses spike currents through passive electromagnetic induction rather than requiring costly active control mechanisms
