Pool Cleaning Robot Wireless Power Interface Without Cables
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pool cleaning robots require cumbersome electrical cables or rely on battery power, which is inefficient and aesthetically unappealing, and submerged electrical devices need tethered power supplies that pose safety risks.
Innovation Solution
A contactless electromagnetic connection (EMC) system using a Tx and Rx module for power transmission, where the Tx is embedded in the pool wall, deck, or floor, and the Rx is attached to the robot, enabling wireless power transfer and communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If electrical cables are used to power pool cleaning robots, then power supply is reliable, but the cables are visible and aesthetically unappealing
Solution Approach 1:
The patent extracts the power transmission function from the visible cable by embedding the transmitter in the pool structure (wall, floor, or deck) and using electromagnetic induction to transfer power wirelessly to the robot, eliminating the need for visible cables while maintaining reliable power supply
2Device complexity
If mechanical galvanic electric power connectors are located at the pool wall, then power transmission is simple, but electrical safety is compromised
Solution Approach 1:
The patent replaces the mechanical galvanic connector system with an electromagnetic induction system where the transmitter is embedded in the pool structure and the receiver is mounted on the robot, enabling contactless power transmission that eliminates electrical safety risks while maintaining simple power transmission
3Ease of operation
If battery operated robots are used, then no cables are needed, but power efficiency is reduced and batteries require charging
Solution Approach 1:
The patent introduces an electromagnetic field as an intermediary between the power source (embedded transmitter) and the robot (equipped with receiver), enabling continuous power supply during operation without the need for batteries or cable connections, thus maintaining power efficiency while achieving cable-free operation
