Autonomous Cleaning Device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing autonomous cleaning devices struggle with simultaneous sweeping and mopping, leading to reduced mopping efficiency and inability to adjust cleaning component heights, causing resistance issues during movement.
Innovation Solution
An autonomous cleaning device with a mobile platform and a dual-mode cleaning module, featuring a wet cleaning module with a lifting structure for adjustable height and a dry cleaning module, enabling efficient sweeping and mopping with improved mobility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a mop is added to an end of the sweeping robot to achieve integrated sweeping and mopping, then the device can perform both functions, but the mopping effect and efficiency are greatly reduced because the mop only moves once along the cleaning trajectory
Solution Approach 1:
The cleaning head is designed with dynamic reciprocating movement capability, allowing it to move back and forth along the cleaning trajectory. This dynamic motion enables the mop to clean the same area multiple times during a single pass of the robot, significantly improving mopping efficiency while maintaining integrated sweeping and mopping functionality
Solution Approach 2:
The cleaning head performs periodic reciprocating movements during the cleaning process. By oscillating the cleaning head back and forth along the trajectory, the system creates multiple cleaning cycles per unit distance, enhancing the mopping effect without requiring separate sweeping and mopping operations
2Reliability
If cleaning components are tightly attached to the surface to be cleaned, then cleaning contact is maintained, but the device encounters large resistance when moving and cannot move freely on the surface
Solution Approach 1:
The cleaning module is equipped with a lifting structure that enables dynamic height adjustment. The cleaning head can be raised or lowered relative to the mobile platform, allowing the system to maintain reliable cleaning contact when needed while restoring mobility when the cleaning head is lifted, thus resolving the contradiction between cleaning reliability and movement ease
