Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the cleaning module height is fixed, then the device structure is simple, but the device cannot maintain tight contact with surfaces of varying heights, resulting in reduced cleaning quality and mobility
Solution Approach 1:
The cleaning module is designed with adjustable height capability, transforming from a static fixed-structure to a dynamic adjustable-structure. This allows the cleaning module to adapt to surfaces of varying heights while maintaining tight contact, resolving the contradiction between adaptability and structural simplicity through controlled dynamic adjustment
Solution Approach 2:
The height parameter of the cleaning module is made variable rather than fixed. By enabling the cleaning module height to change according to surface characteristics, the device achieves adaptability to different surface heights while managing the added complexity through parameter variability
2Manufacturing precision
If the cleaning module maintains tight contact with the surface, then cleaning quality improves, but the device experiences great resistance to movement
Solution Approach 1:
The cleaning module employs dynamic height adjustment during operation, allowing it to maintain optimal contact pressure for cleaning quality while reducing contact pressure during movement phases. This dynamic adjustment resolves the contradiction between maintaining tight contact for cleaning precision and reducing movement resistance
Solution Approach 2:
The cleaning module operates in periodic cycles of tight contact during cleaning and reduced contact during movement. This periodic adjustment of contact pressure enables the device to achieve high cleaning precision when needed while minimizing movement resistance during transit
3Adaptability or versatility
If the cleaning device is designed for flat surfaces only, then the device structure is simplified, but the device cannot be applied in various cleaning environments
Solution Approach 1:
The cleaning device is designed with adjustable height cleaning modules that enable it to perform cleaning functions across multiple surface types and environments. This multi-functionality approach allows a single device structure to adapt to various cleaning environments including flat surfaces, stepped surfaces, and surfaces with obstacles, resolving the contradiction between universality and structural simplicity
Solution Approach 2:
The cleaning device incorporates dynamic height adjustment capabilities that allow it to adapt to different cleaning environments. By making the cleaning module height variable rather than fixed, the device achieves versatility across various surfaces while managing the added complexity through controlled dynamic adjustment mechanisms

AI summary
An automatic cleaning device includes a mobile platform, a lifting station, a cleaning module, a liquid supplying module, and a collecting module. The mobile platform is configured to automatically move in a target direction on a surface to be cleaned. The lifting station is connected to the mobile platform and configured to move upwards or downwards with respect to the mobile platform. The cleaning module is connected to the lifting station and configured to clean the surface to be cleaned; the liquid supplying module is configured to provide cleaning liquid to the surface to be cleaned; and the collecting module is configured to collect the cleaning liquid. A height of the cleaning module of the automatic cleaning device is adjustable, and the automatic cleaning device has a great cleaning strength and is capable of collecting dirty cleaning liquid, thus, the automatic cleaning device can be applied broadly.
