Wet Cleaning Module Lift Structure for Reciprocating Robot Mopping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current cleaning robots are limited in their ability to simultaneously sweep and mop surfaces effectively, as they either require separate devices or have reduced efficiency when attempting to perform both functions simultaneously, especially in environments with more stains or dirty surfaces.
Innovation Solution
An automatic cleaning apparatus with a mobile platform, a wet cleaning module, a lifting and lowering structure, and a driving mechanism that synchronously or asynchronously controls the wet cleaning device, lifting and lowering structure, and cleaning liquid module using a combination of clutches, gear sets, and power structures to enhance cleaning efficiency and adapt to obstacles and undulating surfaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a mop cloth is added to a ground sweeping robot to create an integrated sweeping and mopping robot, then the robot can perform both sweeping and mopping functions, but the mopping efficiency is greatly reduced because the mop cloth only translates on the ground once per movement trajectory
Solution Approach 1:
The patent applies the dynamics principle by introducing a lifting and lowering structure that enables the wet cleaning module to dynamically adjust its position vertically relative to the mobile platform. This allows the mop cloth to perform reciprocating motion (lifting and lowering) in addition to translation, creating multiple cleaning passes per trajectory and significantly improving mopping efficiency while maintaining the integrated cleaning function
Solution Approach 2:
The patent implements periodic action through the reciprocating motion mechanism where the wet cleaning module periodically lifts and lowers during operation. This periodic lifting and lowering creates multiple cleaning cycles along the movement trajectory, ensuring thorough cleaning of stains and dirty areas that would be missed by single-pass translation
2Productivity
If the wet cleaning module is equipped with a reciprocating mechanism to improve cleaning effectiveness, then the cleaning efficiency increases, but the device complexity and driving mechanism workload increase
Solution Approach 1:
The patent applies the merging principle by integrating the lifting and lowering structure with the existing mobile platform and wet cleaning module. The driving mechanism is combined to control both the movement of the mobile platform and the reciprocating motion of the wet cleaning module, reducing overall system complexity while achieving improved cleaning efficiency through coordinated motion control
3Productivity
If the wet cleaning module moves vertically relative to the mobile platform to enable reciprocating motion, then the cleaning effectiveness improves, but the lifting and lowering mechanism requires additional power and increases energy consumption
Solution Approach 1:
The patent applies partial action by implementing lifting and lowering motion only when and where needed for effective cleaning. The wet cleaning module performs reciprocating motion selectively during cleaning operations rather than continuously, and the lifting action is used specifically to create additional cleaning passes in areas requiring thorough cleaning, thereby optimizing energy consumption while maintaining cleaning effectiveness
