Cantilever Power Generation Device with Rotating Attraction Body
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional power generation devices with cantilever-shaped power generation units experience variations in attraction force and position during vibration, leading to unstable amplitude and power generation, due to the movement of the attraction body and the power generation unit.
Innovation Solution
The power generation device incorporates a start-up unit with a rotation supporting point that allows the attraction body to incline in the direction of the power generation unit's inclination, reducing contact area variation and maintaining a stable attraction force, thereby stabilizing the vibration amplitude and power generation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the attraction body moves the power generation unit from start point to end point, then the power generation unit is activated, but the attraction force and position vary during vibration causing unstable amplitude
Solution Approach 1:
The attraction body is configured to rotate about a rotation supporting point, allowing it to dynamically adjust its position and orientation during movement. This rotational capability enables the attraction body to maintain optimal alignment with the power generation unit throughout its trajectory, compensating for positional variations and maintaining consistent attraction force, thereby resolving the contradiction between activation function and force stability.
2Productivity
If the attraction body moves perpendicular to the power generation unit, then the power generation unit deflects and vibrates, but the contact area varies causing attraction force instability
Solution Approach 1:
The attraction body rotates about the rotation supporting point to dynamically adjust its orientation during movement. This rotational motion allows the attraction body to maintain consistent contact area with the power generation unit despite perpendicular movement, thereby maintaining stable attraction force while achieving the required deflection and vibration for power generation.
Solution Approach 2:
The rotation supporting point introduces a rotational degree of freedom (angular dimension) to the attraction body's movement. This additional dimensional capability allows the attraction body to compensate for positional variations in the perpendicular direction, maintaining stable contact area and attraction force while still achieving the necessary movement for power generation activation.

AI summary
A power generation device of the present disclosure has a start-up unit that has an attraction body and moves from a start point toward an end point, and a power generation unit that generates electricity by being vibrated and has a cantilever shape. Then, the attraction body attracts the power generation unit when the start-up unit moves from the start point toward the end point, the power generation unit deflects and inclines due to movement of the attraction body of the start-up unit and the power generation unit toward the end point while the power generation unit is attracted to the attraction body, the attraction body starts to vibrate by separation of the attraction body from the power generation unit, and the attraction body inclines in a direction along an inclination of the power generation unit.
