Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the autonomous cleaning device integrates multiple functional modules to enhance cleaning capability, then the cleaning function becomes stronger, but the internal structure becomes more complex and maintenance difficulty increases
Solution Approach 1:
The autonomous cleaning device is divided into multiple detachable functional modules including a main body module, a sensing module, a drive module, and a cleaning module. Each module can be independently assembled and disassembled, allowing the device to maintain complex functionality while simplifying maintenance and repair operations through modular architecture
2Stability of the object's composition
If the sensing module is integrated into the device body, then the device structure becomes unified, but disassembly time and maintenance difficulty increase significantly
Solution Approach 1:
The sensing module is designed as a detachable component that can be separated from the main body module through a sensing module installation structure. This segmentation allows maintenance personnel to access and repair the sensing module without disassembling the entire device, significantly reducing maintenance time and difficulty while maintaining structural integrity during operation
Solution Approach 2:
The sensing module is extracted as an independent detachable unit from the main device body. The sensing module installation structure provides a dedicated interface that allows the sensing module to be removed and replaced independently, enabling easy maintenance and repair of the sensing components without affecting other parts of the device
3Reliability
If the laser distance sensor is installed in the sensing module, then navigation function is improved, but installation accuracy is affected by positioning errors
Solution Approach 1:
The sensing module installation structure incorporates a self-positioning mechanism that automatically ensures accurate alignment of the laser distance sensor when the sensing module is mounted on the main body module. This self-service positioning system eliminates the need for complex external alignment procedures and ensures consistent installation accuracy without requiring high-precision manual assembly
