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 efficiency
Solution Approach 1:
The cleaning module is designed with adjustable height capability, transitioning from a fixed static structure to a dynamic one that can adapt to different surface heights. This allows the cleaning module to maintain tight contact with surfaces of varying elevations, resolving the contradiction between adaptability and structural simplicity.
Solution Approach 2:
The height parameter of the cleaning module is made variable rather than fixed. By enabling the cleaning module to change its vertical position, the device can accommodate surfaces at different heights while maintaining effective cleaning contact, thus improving adaptability without permanently increasing device complexity.
2Productivity
If the cleaning module maintains tight contact with the surface, then cleaning efficiency is improved, but the device experiences great resistance to movement when not cleaning
Solution Approach 1:
The cleaning module's contact force with the surface is made dynamic rather than constant. The module can adjust its pressure and contact level based on whether the device is in cleaning mode or transit mode, allowing high cleaning efficiency during operation while reducing movement resistance during transportation.
Solution Approach 2:
The cleaning module operates in periodic cycles of tight contact during cleaning phases and reduced contact during transit phases. This periodic adjustment of contact pressure enables the device to achieve high cleaning efficiency when needed while minimizing resistance to movement during non-cleaning periods.
3Ease of operation
If the cleaning module is fixed in position, then the device structure is simple, but the device cannot move freely on the surface, reducing mobility
Solution Approach 1:
The cleaning module is designed with dynamic positioning capability, allowing it to adjust its position relative to the mobile platform. This enables the module to move freely on the surface during cleaning operations while maintaining a relatively simple overall device structure through modular design.
4Adaptability or versatility
If the reciprocating cycle is fixed, then the control system is simple, but the device cannot adapt to different operation environments, reducing cleaning thoroughness
Solution Approach 1:
The reciprocating cycle parameters are made dynamically adjustable rather than fixed. The control system can modify the reciprocating cycle based on detected operation environment conditions, enabling the device to adapt to different cleaning scenarios while maintaining reasonable control system complexity through programmed adjustments.
Solution Approach 2:
The reciprocating cycle control incorporates feedback mechanisms that detect operation environment conditions and automatically adjust the cycle parameters accordingly. This feedback-based adaptation allows the device to optimize cleaning performance for different environments without requiring overly complex manual control systems.

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.
