Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the robot repeatedly adjusts its moving direction to navigate around obstacles, then the robot can maintain its cleaning path, but the adjusting time and energy consumption increase significantly
Solution Approach 1:
The robot body is divided into two independent modules: a fixed functional processing module and a movable moving module. The moving module can independently rotate 360 degrees around the functional module, allowing the robot to change direction without complex adjustments of the entire body, thus reducing adjusting time while maintaining path navigation capability
Solution Approach 2:
The moving module is designed with dynamic rotational capability through a connection mechanism including a rotating joint and ball joint. This allows the moving module to freely rotate and adapt its orientation in real-time when encountering obstacles, enabling quick direction changes without time-consuming adjustments
2Reliability
If the robot repeatedly adjusts its moving direction to navigate around obstacles, then the robot can maintain its cleaning path, but the energy consumption increases significantly
Solution Approach 1:
By segmenting the robot into a fixed functional module and a movable module with independent rotational capability, the system reduces the energy required for direction changes. Only the moving module needs to rotate rather than the entire robot body, significantly reducing energy consumption during obstacle navigation
Solution Approach 2:
The dynamic connection mechanism with rotating and ball joints allows the moving module to rotate with minimal energy input. The mechanical design enables smooth rotation with low friction, reducing the energy required for direction adjustments while maintaining the ability to navigate around obstacles
3Adaptability or versatility
If the robot uses a complex adjustment mechanism to change moving direction, then the robot can navigate obstacles, but the device complexity increases
Solution Approach 1:
The robot is segmented into a fixed functional processing module and a simplified moving module. The moving module contains a straightforward connection mechanism with a rotating joint and ball joint, avoiding complex adjustment mechanisms while maintaining obstacle navigation capability through independent rotation
Solution Approach 2:
The connection mechanism provides dynamic rotational freedom with simple components: a rotating joint allowing 360-degree rotation and a ball joint enabling multi-directional movement. This simple dynamic structure achieves obstacle navigation without requiring complex mechanisms

The robot achieves improved cleaning efficiency with reduced energy consumption and time, as it can easily turn 90 degrees to continue cleaning around obstacles, maintaining performance with the same power and time usage.
Implementation Method 1
the vacuum pump is controlled by the control device to communicate with the suction cup through the gas-guide tube and to vacuumize the suction cup to form negative pressure so as to enable the self-moving robot to adhere to a surface to be treated
