Floating Mop Bracket Structure for Robot Obstacle Crossing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current 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, as they cannot lift the cleaning cloth to overcome higher obstacles or clean effectively around protrusions.
Innovation Solution
A cleaning robot with a cleaning cloth bracket that is floatingly disposed at the base through an elastic member, where the bracket is connected to a raised portion via a soft member, allowing the bracket to deform and maintain contact with the ground while navigating obstacles, composed of soft brackets for enhanced cleaning efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the cleaning cloth bracket is fixed or non-deformable, then the structure is simple and stable, but the robot gets stuck on obstacles and cannot clean effectively around protrusions
Solution Approach 1:
The cleaning cloth bracket is transformed from a fixed structure to a dynamic one by introducing elastic members that allow the bracket to deform and adapt when encountering obstacles. The bracket can elastically deform to lift over obstacles and then return to its original position, enabling the robot to navigate uneven surfaces while maintaining a relatively simple overall structure.
Solution Approach 2:
The bracket's physical state is changed by using elastic materials that can alter their shape and position in response to external forces from obstacles. This parameter change allows the bracket to transition between different states (contacting ground, lifting over obstacles) without requiring complex mechanical mechanisms.
2Force
If the cleaning cloth bracket is lowered only by gravity, then the structure is simple, but the bracket cannot be lifted when encountering obstacles
Solution Approach 1:
The elastic members function as counterweight elements that store potential energy when compressed and release it to lift the bracket over obstacles. This counteracts the gravitational force pulling the bracket down, enabling the bracket to be lifted without requiring additional active lifting mechanisms.
Solution Approach 2:
The elastic members are pre-configured to provide cushioning and lifting force before the robot encounters obstacles. When obstacles are detected or encountered, the elastic members are already in position to deform and lift the bracket, providing immediate resistance against gravitational force without requiring real-time adjustment mechanisms.
3Productivity
If the bracket is lifted by protrusions, then the robot can overcome obstacles, but the ground around the protrusion cannot be cleaned effectively
Solution Approach 1:
The cleaning system is segmented into multiple independent cleaning cloth brackets, each capable of independent deformation and ground contact. This segmentation ensures that when one bracket is lifted by an obstacle, other brackets remain in contact with the ground and continue cleaning, maintaining overall cleaning coverage and efficiency.
Solution Approach 2:
Different parts of the cleaning system have different functions: the elastic members provide lifting capability where needed, while the cleaning cloth brackets maintain ground contact for cleaning. This local differentiation of properties ensures that the lifting mechanism does not compromise cleaning coverage, as each bracket can independently adapt to local terrain conditions.
4Adaptability or versatility
If there is a gap between the side wall and supporting plate, then the structure is simple, but the robot gets stuck when obstacle height is between the side wall and supporting plate
Solution Approach 1:
The bracket structure is made dynamic through elastic members that allow continuous adjustment of the bracket's position and angle. This dynamic capability enables the bracket to adapt to various obstacle heights by deforming to different extents, eliminating the problem of fixed gaps and expanding the range of conquerable obstacles without adding complex adjustable mechanisms.
