AI Technical Summary

Technical Problem

Conventional power generation mechanisms using a cored motor in generators experience mis-engagement between movable parts due to oscillation, limiting the rotation angle and elastic energy storage, thereby restricting the generation of electricity, which in turn restricts the transmission distance of wireless communication devices.

Method used

A power generation device utilizing a coreless motor with a first and second movable part, each with gears, and a torsion coil spring, where the number of teeth on the second movable part is increased, and the elastic energy is stored and managed to prevent oscillation, enhancing the rotation angle and electricity generation.

Benefits of technology

Prevents damage to movable parts, increases the rotation angle and stored elastic energy, leading to higher electricity generation, enabling longer-distance radio wave transmission for wireless communication devices.

Abstract

To provide a power generation device and a power generation method that are able to prevent damage to a movable component, are able to increase the amount of power generated by a power generator and are able to allow a radio communication device to transmit a radio wave to a farther place by the increase in the amount of power.SOLUTION: A power generation device comprises at least a first movable component, a second movable component, a power generator, and a housing. The first movable component and the second movable component are gears, the power generator is a coreless motor, and the number of teeth of the second movable component is three or more. Further, a torsion coil spring is provided. The coil is rotated with respect to a magnet by rotation of a shaft of the coreless motor to generate power by means of the power generator; and by means of initial elastic energy ie1, ie2 of the torsion coil spring caused by rotation of a first central shaft, oscillation of the first central shaft and the first movable component is suppressed to suppress generation of power in a direction opposite to the power generated by the power generator.SELECTED DRAWING: Figure 2
