Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a connecting structure is provided between the mopping disk and the movement mechanism to enable lifting and lowering, then the cleaning element can be lifted during non-mopping operation, but the connecting structure becomes complicated and disassembly becomes inconvenient
Solution Approach 1:
The connecting structure is divided into two detachable parts: a first magnetic attraction assembly on the movement mechanism and a first magnetic part on the cleaning element. This segmentation allows the cleaning element to be easily detached from the movement mechanism while maintaining the lifting function during operation.
Solution Approach 2:
The traditional mechanical connecting structure is replaced with a magnetic attraction system. The first magnetic attraction assembly and first magnetic part create a magnetic connection that enables both attachment and easy detachment, eliminating complex mechanical fasteners while maintaining the lifting and lowering functionality.
2Reliability
If a complicated connecting structure is used between the mopping disk and the movement mechanism, then the cleaning element can be securely attached, but disassembly becomes inconvenient and time-consuming
Solution Approach 1:
The magnetic attraction system replaces mechanical fastening mechanisms, providing reliable attachment through magnetic force while enabling quick release. The cleaning element can be securely held during operation but easily detached by overcoming the magnetic force, significantly reducing disassembly time.
Solution Approach 2:
The magnetic attraction force can be dynamically adjusted by controlling the electromagnet's power consumption. During operation, higher power consumption provides strong attachment reliability. During disassembly, reduced power consumption allows easy separation, thus solving both attachment reliability and disassembly time requirements.
3Stability of the object's composition
If the cleaning element is permanently connected to the movement mechanism, then structural stability is maintained, but maintenance and cleaning become inconvenient
Solution Approach 1:
The system is segmented into detachable components: the cleaning element with first magnetic part and the movement mechanism with first magnetic attraction assembly. This allows the cleaning element to be easily removed for maintenance and cleaning while maintaining structural stability during operation through magnetic attraction.
Solution Approach 2:
The connecting structure transitions from a static permanent connection to a dynamic detachable connection. The magnetic attraction assembly can engage and disengage the magnetic parts, allowing the system to switch between stable operation mode and maintenance mode, improving both structural stability and ease of repair.

AI summary
The present application provides a cleaning robot system, which includes a self-moving cleaning device and a base station. The self-moving cleaning device includes a machine main body, a cleaning element and a movement mechanism. The movement mechanism is connected to the machine main body and the cleaning element to drive the cleaning element to be lifted and lowered relative to the machine main body. The cleaning element and the movement mechanism are detachably connected by means of a first magnetic attraction assembly. The cleaning element is also provided with a first magnetic part. The base station is provided with an electromagnet. A magnetic attraction force between the energized electromagnet and the first magnetic part is greater than a difference between a magnetic attraction force of the first magnetic attraction assembly and a gravitational force of the cleaning element. In this way, automatic disassembly and separation of the cleaning element from the movement mechanism can be achieved, and the whole process eliminates the need for manual operation by a user, thereby improving the operation experience in disassembling the cleaning element.
