Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Capacitive electrical energy storage systems, such as those using super-capacitors, are ineffective in delivering continuous electric currents of significant durations, typically limited to short periods due to charge distribution challenges between capacitors.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If very high capacity capacitors (super-capacitors) are used for storing electrical energy, then the lifespan is improved (greater than lithium batteries), but the ability to deliver electric current for significant durations (order of a day or more) deteriorates
Solution Approach 1:
The patent combines multiple capacitors into a capacitive storage system where energy can be transferred between them. By merging the functionality of multiple capacitors with charge transfer capability, the system achieves both long lifespan (inherent to capacitors) and extended duration current delivery through coordinated operation of multiple units.
Solution Approach 2:
The patent introduces dynamic charge transfer between capacitors using controlled switches. The system dynamically redistributes electrical charges between capacitors based on their charge states, enabling the system to adapt and maintain current delivery capability over extended periods while preserving the long lifespan advantage.
2Stability of the object's composition
If controlled switches and transfer capacitors are used to maintain uniform charge distribution, then charge balance is improved, but device complexity increases
Solution Approach 1:
The patent segments the capacitive storage system into multiple independent capacitor units with individual charge states. By dividing the system into manageable segments, charge distribution can be monitored and adjusted locally between units, maintaining uniformity without requiring complex centralized control of the entire system.
Solution Approach 2:
The patent uses transfer capacitors as intermediary elements between storage capacitors. These intermediary components facilitate charge transfer and balance between capacitors, simplifying the control architecture by providing a dedicated mechanism for charge redistribution rather than requiring direct complex control between all capacitor pairs.
3Productivity
If conventional electron multiplier tubes are used, then current amplification is achieved (up to milliampere level), but the ability to deliver ampere-level currents deteriorates
Solution Approach 1:
The patent replaces conventional electron multiplier tubes (which rely on vacuum tube mechanics and high voltage acceleration) with a solid-state rhodium block device operating at low voltages. This substitution enables current amplification at the ampere level by using a different physical mechanism (magnetic field interaction with rhodium) that does not suffer from the current limitations of vacuum tube technology.
Solution Approach 2:
The patent fundamentally changes the operating parameters of electron multiplication: operating voltage (from hundreds of volts down to 10-24 volts), current level (from milliampere to ampere), and physical state (from vacuum tube to solid block). These parameter changes enable the device to deliver high current intensities while maintaining amplification capability.
