Cleaning Robot Height Adjuster for Multi-Floor Surface Adaptation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Cleaning robots face operational limitations due to height differences between floors, which can lead to malfunctions when trying to clean surfaces with varying heights or materials, such as carpets, as they struggle to adjust their physical properties to match the changing floor conditions.
Innovation Solution
A cleaning robot equipped with a central controller and sensors that adjust the height of its floor cleaner based on pre-stored height information and real-time sensor data, allowing it to adapt its operation to different floor heights and materials, ensuring effective cleaning without damaging the robot's components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the cleaning robot uses a fixed-height floor cleaner structure, then the device complexity is reduced, but the adaptability to different floor heights and materials deteriorates
Solution Approach 1:
The patent implements a height adjuster mechanism that dynamically changes the height of the floor cleaner based on detected floor conditions. The system transitions from a static fixed-height structure to a dynamic adjustable-height structure, allowing the cleaning robot to adapt to various floor heights and materials while maintaining manageable device complexity through automated control.
2Ease of operation
If the cleaning robot operates on floors with height differences without adjustment, then the ease of operation is maintained, but the reliability of cleaning operation deteriorates
Solution Approach 1:
The system employs sensors to automatically detect floor height and material conditions, then autonomously controls the height adjuster to optimize the floor cleaner's position. This self-service mechanism eliminates the need for manual intervention while ensuring reliable cleaning operations across diverse floor conditions, maintaining ease of operation without compromising reliability.
3Loss of time
If the cleaning robot does not adjust to floor height changes, then the loss of time for adjustment is eliminated, but the productivity of cleaning operation deteriorates
Solution Approach 1:
The system performs preliminary detection of floor conditions using sensors before the cleaning operation begins. By detecting floor height and material characteristics in advance, the height adjuster can be pre-positioned to optimal settings, eliminating adjustment delays during cleaning and maintaining high productivity without time loss.
4Manufacturing precision
If the cleaning robot uses a fixed floor cleaner height, then the manufacturing precision requirements are simplified, but the adaptability to different floor materials deteriorates
Solution Approach 1:
The patent implements a system that changes the height parameter of the floor cleaner based on detected floor material and height conditions. Rather than requiring manufacturing precision for all possible floor types, the system uses adjustable height parameters controlled by sensor feedback, allowing adaptation to different floor materials while maintaining reasonable manufacturing tolerances.
