Cleaning robot and cleaning cloth bracket
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current floor cleaning robots with mopping functions are limited by fixed or non-deformable cleaning cloth brackets, which get stuck on obstacles like steps, reducing cleaning efficiency and user experience.
Innovation Solution
A cleaning robot with a cleaning cloth bracket featuring a raised portion connected to the base via a soft member, allowing the bracket to lift and deform to overcome higher obstacles while maintaining contact with the ground for effective cleaning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the cleaning cloth bracket is fixed or cannot move, then the structure is simple and stable, but the robot gets stuck on obstacles and cleaning efficiency is reduced
Solution Approach 1:
The cleaning cloth bracket is transformed from a fixed structure to a dynamic structure that can automatically lift and lower in response to obstacles. The bracket includes a lifting component that raises the bracket when encountering obstacles and a lowering component that returns it to the original position, enabling the robot to maintain cleaning contact while navigating obstacles.
Solution Approach 2:
The bracket structure is divided into multiple independent components: the bracket body, lifting component, lowering component, and cleaning cloth. This segmentation allows each component to perform its specific function independently, with the lifting and lowering mechanisms operating separately to achieve obstacle navigation while maintaining cleaning effectiveness.
2Productivity
If the bracket is lifted by protrusion, then the robot can overcome obstacles, but the ground around the protrusion cannot be cleaned
Solution Approach 1:
The cleaning cloth bracket employs dynamic lifting and lowering mechanisms that enable selective elevation. When encountering obstacles, only the necessary portion of the bracket is lifted to clear the obstacle, while other portions remain in contact with the ground to continue cleaning, thus maintaining both obstacle overcoming capability and cleaning coverage.
Solution Approach 2:
Different parts of the bracket have different functions: some portions are designed to lift and overcome obstacles, while other portions maintain contact with the ground for cleaning. This local differentiation ensures that obstacle navigation and cleaning operations occur simultaneously without compromising either function.
3Productivity
If the side wall height is limited, then the bracket structure is compact, but the robot gets stuck on obstacles of medium height
Solution Approach 1:
Instead of increasing the static height of the bracket to overcome taller obstacles, the invention uses dynamic lifting mechanisms that temporarily raise the bracket only when obstacles are detected. This allows the bracket to overcome obstacles of various heights without requiring a permanently larger bracket structure, maintaining compact dimensions while achieving greater obstacle clearance capability.
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
The solution enhances the robot's ability to navigate higher obstacles and improves cleaning efficiency by ensuring the cleaning cloth remains in contact with the ground, expanding its operational range and cleaning effectiveness.
