Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Resonance circuits face challenges in achieving high voltage output and extended operation time while minimizing power consumption from a power source, and their portability is limited due to the need for a constant power source connection.
Innovation Solution
An electric circuit incorporating a supercapacitor and a toroid inductor with adjustable primary and secondary windings, along with a transistor and biasing resistors, allows for energy harvesting from nearly depleted batteries, enabling high voltage output and extended operation by alternating between saturation and cut-off regions at a resonance frequency, disconnecting the power source for portability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If resonance circuits use more turns in primary and secondary windings to increase voltage output, then voltage output is improved, but operation time decreases
Solution Approach 1:
The patent applies parameter changes by optimizing the number of turns in primary and secondary windings to achieve a balance between voltage output and operation time. The circuit allows adjustment of winding parameters to resolve the contradiction between high voltage output and extended operation duration.
2Reliability
If resonance circuits are connected to power source at all times to ensure continuous operation, then reliability is improved, but portability deteriorates
Solution Approach 1:
The patent applies preliminary action by pre-charging the supercapacitor before disconnecting the power source. This allows the circuit to operate independently for extended periods, achieving both reliability through continuous operation capability and portability through power source disconnection.
Solution Approach 2:
The patent uses a supercapacitor as an intermediary energy storage device between the power source and the resonance circuit. This mediator enables the circuit to operate without continuous power source connection, improving portability while maintaining reliability through the supercapacitor's energy buffer.
3Duration of action of moving object
If resonance circuits use minimum power from power source to extend operation time, then duration of action is improved, but voltage output deteriorates
Solution Approach 1:
The patent resolves this contradiction by optimizing circuit parameters including the number of turns in windings, inductance values, and capacitance to achieve efficient energy transfer. This allows extended operation time while maintaining sufficient voltage output through parameter optimization rather than simply reducing power consumption.

AI summary
The present disclosure describes an electric circuit for powering a connectable load. The electric circuit includes a supercapacitor configured for connection in parallel to a removable power source capable of charging the supercapacitor, a toroid inductor having a primary winding and a secondary winding, a base biasing resistor, and a transistor. The secondary winding connected in series to the base biasing resistor, and to the base, the primary connected to the collector, the emitter connected the supercapacitor, and the load connected across the collector-emitter junction of the transistor. When the charged supercapacitor discharges, the primary and secondary windings incite the transistor to alternate between a saturation region and a cut off region at a resonance frequency, directing current to the supercapacitor through the collector-emitter junction of the transistor while in the saturation region, and directing current with high voltage to the load while in the cut off region.
