Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the receiving induction element directly supplies energy to the further unit without voltage conversion, then the system structure is simple, but the receiving induction element and voltage regulator are prone to overloading and failure
Solution Approach 1:
A voltage converter unit is introduced as an intermediary component between the receiving induction element and the further unit. This voltage converter includes a voltage cascade with multiple stages (first voltage cascade stage, second voltage cascade stage) that step-wise converts the induced voltage, preventing direct overload of the receiving induction element and voltage regulator while improving system reliability.
2Loss of energy
If the electrical voltage is not converted for the further unit, then the system has fewer components, but electrical losses are high and energy supply is inefficient
Solution Approach 1:
The voltage converter unit changes the voltage parameter through a cascade configuration with multiple stages. The first voltage cascade stage converts the electrical voltage to an intermediate level, and the second voltage cascade stage further converts it to the final operating voltage for the further unit. This multi-stage parameter transformation reduces electrical losses and improves energy supply efficiency.
