Solution Overview
Problem
Existing reciprocating devices require complex construction and increased costs due to the need for power transmission units along the track, and they cannot move a movable body while its battery is uncharged.
Innovation Solution
A reciprocating device with a movable body that receives electric power wirelessly from power transmission units at both ends of the track, using magnetic field resonance, electric field resonance, or electromagnetic induction for efficient power transmission, allowing the movable body to move along the track with reduced power consumption and simplified construction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a pair of feeders are arranged along the track to supply power wirelessly, then the movable body can be reciprocated along the track, but the construction becomes complicated and costs increase
Solution Approach 1:
The track is divided into multiple sections with power transmission units positioned at both ends, allowing the movable body to receive power from either end depending on its position. This segmentation eliminates the need for continuous feeder arrangement along the entire track, simplifying construction while maintaining reliable power supply.
Solution Approach 2:
Power transmission is achieved from both ends of the track simultaneously, creating a bidirectional power supply system. This dimensional change from unidirectional to bidirectional power transmission reduces the need for extensive feeder infrastructure along the track length.
2Reliability
If wireless power transmission is used to charge the battery, then the movable body can be stationary during charging, but it cannot move while the battery is uncharged
Solution Approach 1:
The movable body continuously receives power wirelessly from both ends of the track during movement, eliminating interruptions in power supply. This continuous power transmission enables the movable body to move throughout the entire track without needing to stop for charging, maintaining both reliability and mobility.

AI summary
In a reciprocating device, first and second power transmission units are provided on one end side and the other end side of a track to put therebetween power receiving units which are provided on a movable body being movable along the track. Thus, when the movable body is moved close to the one end side or the other end side of the track to separate the power receiving units far from the second power transmission unit on the other end side or the first power transmission unit on the one end side, the power receiving units are able to efficiently receive the electric power from the first power transmission unit on the one end side or the second power transmission unit on the other end side which is close thereto. Therefore, it is possible to reciprocate the movable body between the both ends of the track in a simplified construction.
