Voltage Conversion for Reliable Electric Human-Powered Vehicles
Here’s PatSnap Eureka !
Summary
Problems
Human-powered vehicles with electric units face usability issues due to voltage mismatch between the electric power source and the actuator driver, leading to inefficient operation and potential damage.
Innovation solutions
Incorporating a converter circuit that adjusts the voltage from a first voltage to a second voltage, suitable for the actuator driver, by being electrically connected in series with the input part and actuator driver, allowing for selective use of multiple power sources and threshold-based voltage conversion.

Specific contradictions:
General conflict description:
Principle concept:
If a fixed voltage electric power source is used, then the device structure is simple, but the device cannot adapt to different voltage requirements of actuator drivers
Why choose this principle:
The patent applies parameter changes by converting the fixed voltage output of the electric power source to a variable voltage that matches the actuator driver's requirements. The converter circuit dynamically adjusts the voltage parameter based on the actuator driver's needs, enabling the system to adapt to different voltage requirements while maintaining a simple overall structure.
Principle concept:
If a fixed voltage electric power source is used, then the device structure is simple, but the device cannot adapt to different voltage requirements of actuator drivers
Why choose this principle:
The converter circuit serves as an intermediary component between the electric power source and the actuator driver. It mediates the voltage mismatch by transforming the power source's fixed voltage into the appropriate voltage for the actuator driver, thus resolving the contradiction between simple structure and voltage adaptability.
