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 power supply and communication are enabled, but the robot becomes prone to entanglement and blockage, limiting its freedom of movement
Solution Approach 1:
The patent extracts the power supply function from the trailing cable by equipping the robot with an independent battery system. The battery is mounted on the robot's chassis and provides autonomous power supply, completely eliminating the physical cable connection. This allows the robot to move freely without cable entanglement while maintaining reliable power supply throughout the cleaning cycle.
Solution Approach 2:
The patent replaces the mechanical cable connection with wireless communication technology. Commands and data are transmitted between the control device and the robot using radio frequency or other wireless protocols, eliminating the need for a physical trailing cable. This substitution enables complete freedom of movement while maintaining reliable communication and control.
2Use of energy by moving object
If a trailing cable is used for power supply, then continuous power can be provided, but the cable causes tangling and blockage issues that hinder cleaning efficiency
Solution Approach 1:
The robot is equipped with a battery that is charged in advance before deployment. This preliminary energy storage allows the robot to operate autonomously for the entire cleaning cycle without requiring a trailing cable for continuous power supply. The battery capacity is calculated to ensure sufficient energy for complete pool cleaning, eliminating productivity losses from cable management issues.
3Ease of operation
If wireless communication is used instead of cable connection, then freedom of movement is improved, but communication reliability may be affected by water interference
Solution Approach 1:
The patent uses an antenna as an intermediary device for wireless communication. The antenna is strategically positioned on the robot's exterior to optimize signal transmission and reception through water. The control device and robot communicate via wireless signals that penetrate water effectively, maintaining reliable communication while enabling complete freedom of movement. The system includes signal strength monitoring and automatic reconnection capabilities to ensure communication reliability.
