Solution Overview
Problem
There is a growing need to interact with a submerged cordless pool-related platform, such as a robot, without the use of a power and communication cable, while ensuring effective communication and control.
Innovation Solution
A partially submerged system that uses unique sound signals, such as ultrasonic signals within the 11 KHz-12 KHz range, to interact with submerged robots. These signals can convey commands, requests, or information and are designed to propagate effectively through water, allowing for communication and control of the submerged robot.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a power and communication cable is used to convey commands to the submerged robot, then reliable communication and power supply are achieved, but physical interaction and cable management become necessary
Solution Approach 1:
The patent replaces the mechanical cable-based communication and power transmission system with an acoustic signal transmission system. The above-water device transmits acoustic signals that penetrate the water surface to convey commands to the submerged robot, eliminating the need for physical cable connection while maintaining communication capability.
Solution Approach 2:
The patent introduces acoustic signals as an intermediary medium to transfer commands from the above-water device to the submerged robot. The acoustic signal acts as a mediator that can traverse the air-water interface, enabling communication without direct physical contact or cable connection.
2Ease of operation
If cordless operation is implemented to prevent physical interactions with cables, then user convenience and safety are improved, but communication and control capability may be compromised
Solution Approach 1:
The patent substitutes the mechanical cable connection with acoustic signal transmission, enabling cordless operation while maintaining command transmission capability. The acoustic signals carry control information from the above-water device to the submerged robot without requiring physical connection.
Solution Approach 2:
Acoustic signals serve as an intermediary carrier for command transmission, allowing the submerged robot to receive control instructions without cable connection. This intermediary approach preserves information transmission capability while achieving cordless operation.
3Adaptability or versatility
If acoustic signals are used to communicate with the submerged robot, then cable-free operation is achieved, but signal propagation effectiveness through water must be ensured
Solution Approach 1:
The patent utilizes specific acoustic signal parameters (frequency, wavelength) that are optimized for propagation through water. By selecting appropriate acoustic parameters, the system achieves effective signal transmission across the air-water interface and through the water medium to the submerged robot.
