Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a trailing cable is used to supply power and transmit commands to the underwater cleaning robot, then the robot can receive power and control signals, but the cable may tangle or block the robot during movement
Solution Approach 1:
The patent extracts the trailing cable from the system by implementing wireless power transmission and communication. The robot receives power inductively through a power receiving unit with coils, and communication is established wirelessly via acoustic modems, eliminating the physical cable that causes tangling and blocking during robot movement.
Solution Approach 2:
The patent replaces the mechanical cable connection with non-contact power transmission and acoustic communication systems. The mechanical constraint of the cable is substituted by electromagnetic fields for power transfer and acoustic waves for data transmission, allowing the robot to move freely without physical constraints.
2Reliability
If software is used to prevent the robot from getting tangled in cables or blocking itself, then the robot can avoid some cable-related issues, but the software complexity increases
Solution Approach 1:
The patent removes the root cause of cable tangling and blocking by eliminating the cable itself through wireless power and communication systems. This extraction approach is more effective than software workarounds, as it prevents the problem at its source rather than requiring complex software to manage cable constraints.
3Ease of operation
If the robot operates autonomously without a trailing cable, then the robot gains freedom of movement, but a reliable power supply and communication method must be established
Solution Approach 1:
The patent substitutes mechanical cable connections with inductive power transmission using electromagnetic fields and acoustic communication using sound waves. The power receiving unit with coils enables wireless power transfer, while acoustic modems provide bidirectional communication, together forming a complete wireless system that enables robot autonomy.
Solution Approach 2:
The patent implements a multi-functional wireless system where inductive power transmission provides both power supply and a degree of positioning information, while acoustic modems handle bidirectional communication including commands, status reports, and navigation data. This universal wireless approach replaces multiple cable functions with integrated non-contact systems.

AI summary
An underwater cleaning robot contains a movement device for moving the underwater cleaning robot under water, a cleaning device for cleaning an object located under water, a control device for controlling the movement device and/or the cleaning device and a communication device for receiving and/or transmitting signals from outside the underwater cleaning robot and vice versa. The communication device contains a first ultrasonic transducer for receiving ultrasonic signals transmitted under water and is designed to transmit electrical signals, corresponding to the ultrasonic signals received, to the control device.
