Solution Overview
Problem
Current cleaning robots are limited by their single-function design, requiring separate ground sweeping and mopping robots, which occupy more space and can leave areas unclean due to mismatched cleaning widths, leading to inefficient cleaning processes.
Innovation Solution
An automatic cleaning apparatus with a moving platform featuring both dry and wet cleaning modules, where the wet cleaning module's cleaning head has a narrower width than the dry cleaning module, allowing for simultaneous sweeping and mopping with the dry module leading and the wet module following, and incorporating a driving unit and vibration mechanism for enhanced cleaning efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the width of the mop is equal to the width of the bottom surface of the cleaning apparatus, then the wet cleaning module can cover the entire width, but the dry cleaning module cannot cover the same area, causing some ground areas to be mopped before sweeping
Solution Approach 1:
The patent applies asymmetry by making the cleaning head width of the wet cleaning module smaller than the width of the dry cleaning module. Specifically, the dry cleaning module has a larger cleaning width while the wet cleaning module has a narrower cleaning head, creating an asymmetric configuration that ensures the dry module leads and covers a broader area, preventing the wet module from cleaning unswept areas
Solution Approach 2:
The patent implements preliminary action by positioning the dry cleaning module to lead the wet cleaning module during operation. The dry cleaning module performs sweeping first on a broader area, and only then does the wet cleaning module follow to mop the already-swept area, ensuring that wet cleaning only occurs after dry cleaning has prepared the surface
2Reliability
If separate ground sweeping robot and ground mopping robot are used, then each robot can perform its specialized function, but double space is occupied and structure design becomes unreasonable
Solution Approach 1:
The patent merges the functions of separate ground sweeping and ground mopping robots into a single integrated cleaning apparatus. The device combines a dry cleaning module for sweeping and a wet cleaning module for mopping, allowing both functions to be performed by one robot, thereby reducing space occupation and simplifying structural design while maintaining specialized cleaning capabilities
Solution Approach 2:
The patent achieves universality by designing a multi-functional cleaning robot that can perform both dry sweeping and wet mopping operations. The apparatus is equipped with interchangeable or simultaneously operable dry cleaning modules and wet cleaning modules, enabling a single device to handle multiple cleaning tasks that previously required separate specialized robots
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This design ensures thorough cleaning by preventing the wet module from cleaning areas not swept by the dry module, enhancing cleaning effectiveness, especially in areas with stains, by allowing multiple passes over a single area.
Implementation Method 1
a cam 4212 connected with the motor output shaft and having an asymmetric structure; and a vibrating rod 4213 arranged on a side of the driving platform 421 opposite to the motor 4211, connected with the cam 4212, and reciprocating under an asymmetrical rotation of the cam 4212
