Sliding Magnet Power Generation Device for Thin Profiles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional power generation devices are difficult to make thinner in size due to their configuration, which limits their compactness for use in electronic equipment and remote control operation devices.
Innovation Solution
The configuration includes a first magnet member with one polarity and a second magnet member with opposite polarity, a yoke disposed between them, and an induction coil at the yoke's periphery, allowing sliding movement to change the magnetic flux direction and induce an electromotive force, thereby enabling a thinner design.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If conventional power generation device configuration is used, then power generation function is achieved, but device thickness cannot be reduced
Solution Approach 1:
The patent transitions from a conventional rotational motion configuration to a sliding motion configuration. The movable-side part with magnet members slides horizontally relative to the fixed-side part with yoke members, changing the dimension of motion from rotational to linear sliding. This dimensional change enables the device to achieve power generation in a thinner profile while maintaining the essential function of magnetic flux change and electromotive force induction.
2Device complexity
If magnet member rotates to induce electromotive force, then power generation is achieved, but device structure becomes complex and thick
Solution Approach 1:
The patent replaces the conventional rotational mechanical system with a sliding mechanical system. Instead of rotating the magnet member around an axis, the movable-side part slides horizontally relative to the fixed-side part. This substitution simplifies the mechanical structure by eliminating rotational components and bearings, reducing device complexity and thickness while maintaining the ability to change magnetic flux and generate power through the sliding motion.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This configuration allows for the creation of a power generation device that is thinner in size, suitable for a wide range of electronic equipment and remote control operation devices, enhancing compactness without compromising power generation efficiency.
Implementation Method 1
an induction coil disposed at the periphery of the yoke. When the first magnet member and the second magnet member slidingly move in synchronization with each other, or alternatively the yoke slidingly moves, the direction in which the magnetic flux flows in the yoke changes to induce an electromotive force in the induction coil.

AI summary
A power generation device includes a first magnet member, a second magnet member which is disposed such that the N pole side thereof is in the opposite direction to the N pole side of the first magnet member, a yoke which is disposed between the first magnet member and the second magnet member, an induction coil which is disposed at an outer periphery of the yoke. When the first magnet member and the second magnet member slidingly move in synchronization or when the yoke slidingly moves, the direction of a magnetic flux flowing in the yoke changes to generate an electromotive force in the induction coil.
