Solution Overview

Problem

Current mobile cleaning robots lack situational awareness, failing to adapt their cleaning operations based on the dynamic environment and user preferences, leading to inefficient cleaning and potential interference with daily activities.

Innovation Solution

A mobile cleaning robot equipped with artificial intelligence, featuring a camera system, recognition module, and control module that uses neural networks to recognize objects, adapt cleaning modes, and schedule tasks based on environmental changes and user preferences, including the presence of people, pets, and foot traffic patterns.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If the robot performs thorough cleaning in all areas, then cleaning quality is improved, but it may interfere with user activities and cause loss of time

Engineering Contradiction:
Improvecleaning qualityVSAvoiduser activity interruption
Core Design Contradiction:
Manufacturing precisionVSLoss of time

Solution Approach 1:

The robot dynamically adjusts its cleaning behavior based on real-time environmental recognition. When objects like chairs or user activities are detected, the robot modifies its cleaning path and intensity accordingly, transitioning between different cleaning modes to balance thoroughness with user convenience

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The robot uses camera-based object recognition to continuously monitor the environment and provides feedback to its control system. This feedback loop enables the robot to adapt its cleaning operations in real-time, avoiding areas where users are active or objects need to remain undisturbed

Inventive Principle:
Principle #23Feedback

2Productivity

If the robot adapts to dynamic environment and user preferences, then cleaning efficiency is improved, but device complexity increases

Engineering Contradiction:
Improvecleaning efficiencyVSAvoidsystem complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The robot autonomously performs environmental assessment, object recognition, and cleaning plan adjustment without user intervention. The system self-adapts to changing conditions by automatically recognizing objects and modifying its behavior, reducing the need for complex user-programming interfaces

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent replaces traditional mechanical obstacle avoidance sensors with vision-based object recognition systems. This substitution enables more sophisticated environmental understanding and adaptive behavior while maintaining a relatively simple physical structure

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

3Device complexity

If the robot uses traditional cleaning operations, then device complexity is kept low, but it cannot respond to environmental changes and user needs

Engineering Contradiction:
Improvesystem complexityVSAvoidenvironmental responsiveness
Core Design Contradiction:
Device complexityVSAdaptability or versatility

Solution Approach 1:

The robot integrates multiple functions into a single system: navigation, object recognition, environmental mapping, and adaptive cleaning control all work together within one platform. The camera system serves multiple purposes including obstacle detection, object identification, and environmental monitoring

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

4Ease of operation

If the robot cleans without situational awareness, then ease of operation is maintained, but cleaning effectiveness decreases due to inability to avoid obstacles and adapt to conditions

Engineering Contradiction:
Improveoperational simplicityVSAvoidcleaning effectiveness
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The robot autonomously performs environmental assessment, object recognition, and cleaning plan adjustment without user intervention. The system self-adapts to changing conditions by automatically recognizing objects and modifying its behavior, reducing the need for complex user-programming interfaces

Inventive Principle:
Principle #25Self-service
