Adjustable parameters for autonomous cleaning robots
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cleaning robots lack the ability to adjust their cleaning performance based on room size or dirt/debris levels, leading to either inadequate cleaning or excessive overlap, which affects their efficiency and coverage.
Innovation Solution
An autonomous cleaning robot system that allows users to select from multiple cleaning levels and spray levels through a mobile device interface, adjusting rank overlap parameters and fluid ejection characteristics to optimize cleaning missions based on user input, enabling deeper or broader cleaning coverage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a relatively large rank overlap is used, then cleaning performance is improved, but coverage area decreases
Solution Approach 1:
The patent applies dynamics by making the rank overlap parameter adjustable rather than fixed. The system allows users to dynamically change the overlap percentage based on specific cleaning needs, enabling the robot to adapt between deep cleaning mode (higher overlap) and coverage mode (lower overlap) without hardware modifications.
Solution Approach 2:
The patent implements parameter changes by varying the rank overlap percentage as a controllable variable. Different overlap parameters (e.g., 0-30% for coverage, 40-70% for deep cleaning) are provided as selectable options, allowing the system to optimize performance by changing this key parameter based on the cleaning scenario.
2Area of stationary object
If a relatively small rank overlap is used, then coverage area is increased, but cleaning performance decreases
Solution Approach 1:
The system enables dynamic adjustment of the rank overlap parameter, allowing users to switch between coverage-optimized settings (lower overlap) and performance-optimized settings (higher overlap) based on the specific cleaning requirements of different areas.
Solution Approach 2:
The patent provides different parameter ranges for different cleaning objectives: lower overlap values (0-30%) for maximizing coverage in large spaces, and higher overlap values (40-70%) for ensuring thorough cleaning in areas with heavy dirt or debris.
3Device complexity
If fixed cleaning parameters are used, then device complexity is reduced, but adaptability to different cleaning scenarios decreases
Solution Approach 1:
The patent implements a dynamic parameter selection system where users can choose from multiple predefined cleaning levels (e.g., low, medium, high overlap) or custom percentages. This provides adaptability without requiring complex real-time sensing and adjustment mechanisms.
Solution Approach 2:
The system offers a range of selectable parameter values (different overlap percentages and spray levels) that can be chosen based on cleaning needs. This allows the robot to adapt to various scenarios through parameter selection rather than through complex structural changes.
4Adaptability or versatility
If adjustable cleaning parameters are provided, then adaptability to different cleaning scenarios is improved, but device complexity increases
Solution Approach 1:
The patent provides adjustable parameters through a user interface that allows selection from predefined cleaning levels or custom percentage inputs. This dynamic adjustment capability is implemented through software control rather than complex mechanical systems, maintaining relatively simple device architecture.
Solution Approach 2:
The system enables parameter adjustment by providing users with selectable options for different cleaning scenarios. The complexity is managed by offering predefined ranges (e.g., 0-30% for coverage, 40-70% for deep cleaning) rather than requiring users to understand or calculate optimal values.
5Reliability
If higher spray volume is used, then cleaning performance is improved, but fluid consumption increases
Solution Approach 1:
The patent provides adjustable spray parameters including volume and frequency. Users can select from different spray levels or custom percentages, allowing optimization between cleaning effectiveness and fluid consumption based on the specific cleaning needs of different areas.
6Quantity of substance
If lower spray volume is used, then fluid consumption is reduced, but cleaning performance decreases
Solution Approach 1:
The system allows parameter adjustment for spray volume and frequency, enabling users to select lower spray levels for areas with light dirt to conserve fluid, or higher levels for heavily soiled areas to maintain cleaning effectiveness.

AI summary
A method of operating an autonomous cleaning robot includes presenting, on a display of a mobile device, a representation of each of multiple cleaning levels, each cleaning level corresponding to a respective rank overlap parameter for a wet cleaning mission of the autonomous cleaning robot. The method includes receiving, at the mobile device, an input indicative of a selection of one of the cleaning levels; and controlling the autonomous cleaning robot to execute a wet cleaning mission according to the rank overlap parameter corresponding to the selected one of the cleaning levels.
