Solution Overview

Problem

Autonomous mobile cleaning robots are often inadequately configured to handle a variety of cleaning surfaces, as they typically come with a single hardware setup optimized for either hard or carpeted surfaces, making them sub-optimal for environments with mixed surfaces.

Innovation Solution

The robot analyzes its environment using maps and sensor data to recommend specific hardware upgrades, such as rollers, casters, or side brushes, to improve cleaning efficiency based on surface types and usage patterns, allowing users to replace or adjust components for better performance.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If a single hardware configuration is provided for the cleaning robot, then the device complexity is reduced and manufacturing is simplified, but the cleaning effectiveness deteriorates on mixed surfaces

Engineering Contradiction:
Improvehardware configuration simplicityVSAvoidcleaning effectiveness
Core Design Contradiction:
Ease of manufactureVSReliability

Solution Approach 1:

The cleaning robot's hardware is divided into separate, interchangeable modules including rollers, side brushes, and casters. Each module can be independently selected and replaced based on the specific surface type (hard floor, carpet, tile) to optimize cleaning performance for different environments.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The cleaning robot is designed with a universal base platform that can accommodate multiple types of cleaning modules. This allows a single robot chassis to perform effectively on various surface types by swapping modules, making the system multi-functional across different cleaning scenarios.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Reliability

If the cleaning robot is optimized for one surface type, then cleaning effectiveness improves on that specific surface, but adaptability to other surfaces deteriorates

Engineering Contradiction:
Improvecleaning effectivenessVSAvoidsurface type compatibility
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The cleaning robot system transitions from a static, fixed configuration to a dynamic, reconfigurable system. Users can adapt the hardware configuration by replacing rollers, side brushes, and casters based on the specific surface type encountered, allowing the system to optimize performance for each environment dynamically.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

Different hardware modules have varying physical parameters (roller diameter, brush length, caster wheel size) that are selected based on the surface type. By changing these physical parameters of the cleaning components, the system adapts to different surface characteristics while maintaining effective cleaning performance.

Inventive Principle:
Principle #35Parameter changes

3Adaptability or versatility

If multiple hardware configurations are provided, then adaptability to different surfaces improves, but device complexity and ease of operation worsen

Engineering Contradiction:
Improvesurface type compatibilityVSAvoidhardware configuration management
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The system provides self-service through automated recommendations. The cleaning robot uses sensor data and environment maps to automatically identify surface types and generate hardware replacement recommendations, reducing the user's burden in determining the appropriate configuration.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The system incorporates feedback loops where sensor data from the cleaning robot is continuously analyzed to assess surface types and cleaning performance. This feedback is used to generate real-time hardware recommendations, creating a closed-loop system that adapts to environmental conditions and guides users in optimizing their robot configuration.

Inventive Principle:
Principle #23Feedback

AI summary

A method of assisting user-configuration of hardware for a mobile autonomous cleaning robot can include detecting a flooring type of a room or other portion of an environment. A size of the portion of the environment can be detected and a total size of the environment can be determined. Generating a hardware characteristic recommendation can be generated based at least in part on the flooring type, the size of the portion of the environment, and the total size of the environment.
