Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the cleaning robot attempts to climb the base station on slippery ground, then the robot may reach the base station for maintenance, but the climbing operation is affected and docking reliability deteriorates
Solution Approach 1:
The patent introduces an extension plate as an intermediary component between the base station and the cleaning robot. This extension plate provides additional support surfaces and anti-slip portions that mediate the interaction between the robot's travelling device and the base station, enabling reliable docking even on slippery ground by distributing the climbing load across multiple contact points
Solution Approach 2:
The base station baseboard is segmented into multiple functional components: substrate, extension plate, slope portion, and anti-slip portions. This segmentation allows each component to perform a specific function in the climbing process, breaking down the challenging single-step climb into multiple manageable stages with intermediate support points
2Reliability
If the base station uses a fixed baseboard design, then the structure is simple, but the cleaning robot cannot successfully dock on slippery surfaces
Solution Approach 1:
The extension plate is designed to be pivotally connected to the substrate, allowing it to rotate between a folded state (when not needed) and an unfolded state (when docking is required). This dynamic configuration enables the base station to adapt its structure based on operational needs, providing enhanced docking capability only when necessary while maintaining structural simplicity at other times
Solution Approach 2:
The base station structure changes its geometric parameters dynamically through the pivotal extension plate. When unfolded, the extension plate increases the effective length and modifies the angle of the baseboard, creating a more favorable climbing geometry for the cleaning robot. This parameter change allows the same structure to serve different functions under different conditions
