Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If conventional energy regenerating methods are used (mechanical energy storage in flywheel or magnetic energy storage in magnetic circuit), then some form of energy can be regenerated, but the load current used to operate the load and the voltage-converted current conducted through the converter cannot be regenerated, resulting in energy wastage
Solution Approach 1:
The patent changes the fundamental parameters of energy storage by transitioning from mechanical/f magnetic storage to electrical storage using capacitor banks. The system uses first and second capacitor banks that can be switched between series and parallel configurations, enabling the regeneration of load current and voltage-converted current through electrical parameter manipulation rather than mechanical or magnetic means
Solution Approach 2:
The regenerating circuit is designed to handle multiple types of current (load current and voltage-converted current) and can operate in different modes (series/parallel switching of capacitor banks), making it a universal solution that can regenerate various forms of electrical energy rather than being limited to a single energy type
2Loss of energy
If the circuit switches between series and parallel connections of capacitor banks to regenerate energy, then load current and voltage-converted current can be recycled, but the voltage gradually drops requiring complex switching control
Solution Approach 1:
The system employs periodic switching between series and parallel connections of the capacitor banks. The switching unit alternates between connecting the capacitor banks in series during energy regeneration phases and in parallel during voltage stabilization phases, creating a periodic action that maintains energy recycling efficiency while managing voltage drops through rhythmic configuration changes
Solution Approach 2:
The circuit configuration is made dynamic through the switching unit that can change the connection topology of the capacitor banks from series to parallel and vice versa. This dynamic reconfiguration allows the system to adapt to varying voltage conditions and load requirements, enabling effective energy recycling while compensating for voltage drops through real-time structural changes
3Loss of energy
If recharging and discharging elements are used to regenerate energy, then energy efficiency is enhanced, but the circuit structure becomes more complex with additional components
Solution Approach 1:
The patent merges the functions of recharging and discharging elements into a unified capacitor bank system. The first and second capacitor banks serve dual purposes as both recharging units (when connected in parallel to the power source) and discharging units (when connected in series to supply energy to the load), eliminating the need for separate recharging and discharging component sets and reducing overall circuit complexity while maintaining high energy efficiency
