Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a complex wheel assembly design is used to ensure secure attachment, then the reliability of the wheel assembly is improved, but the ease of mounting and dismounting deteriorates
Solution Approach 1:
The wheel assembly is divided into separate components: a wheel body, a mounting bracket, and an elastic buckle mechanism. This segmentation allows the wheel to be easily attached and detached while maintaining secure connection during operation. The mounting bracket separates the wheel body from the device body, enabling simple installation and removal.
Solution Approach 2:
The elastic buckle mechanism provides dynamic adjustment capability, allowing the wheel assembly to transition between a secured state during operation and an easily removable state for maintenance. The elastic component enables the structure to adapt between tight connection and flexible disassembly.
2Reliability
If a complex wheel assembly design is used to ensure stable operation, then the reliability is improved, but the device complexity increases
Solution Approach 1:
The wheel assembly uses segmented design with separate mounting bracket and wheel body components. This reduces overall complexity by allowing each component to be optimized independently while maintaining stable operation through their coordinated connection.
Solution Approach 2:
The mounting bracket acts as an intermediary component between the wheel body and device body, simplifying the connection mechanism while ensuring stable operation. This intermediate structure reduces complexity by providing a standardized interface that ensures reliable attachment without requiring complex integration.
3Reliability
If traditional mounting methods are used to ensure secure attachment, then the reliability is improved, but the ease of repair and maintenance deteriorates
Solution Approach 1:
The wheel assembly is designed as separable components that can be easily removed and replaced. The mounting bracket and elastic buckle mechanism enable quick detachment of the wheel body, facilitating maintenance and repair without requiring complex disassembly procedures while maintaining secure attachment during normal operation.
Solution Approach 2:
The design allows for easy replacement of worn or damaged wheel components. The elastic buckle mechanism enables quick removal of the wheel body for maintenance, and the modular structure allows individual components to be replaced or recovered independently, simplifying repair processes.
4Device complexity
If a compact mounting structure is used to save space, then the device complexity is reduced, but the ease of mounting in narrow spaces deteriorates
Solution Approach 1:
The mounting bracket extends the attachment structure in a direction perpendicular to the wheel rotation plane, providing access for mounting operations from the side rather than requiring access only from the wheel center. This dimensional change enables easier mounting in narrow spaces while maintaining a simple overall structure.

Function Achieved in This Case
Facilitates easy mounting and dismounting of the universal wheel assembly in tight spaces, simplifies maintenance, and enhances the mobility of intelligent cleaning devices by providing a secure and efficient attachment mechanism.
Implementation Method 1
the elastic buckle is squeezed to a deformed position when the rotating shaft is inserted into the rotating shaft support, and the elastic buckle is reset to an initial position by means of elastic force when the rotating shaft is inserted in place, to restrict movement of the rotating shaft toward the universal wheel support
