Solution Overview

Problem

Conventional robot cleaners lack the ability to automatically prioritize and intensively clean specific areas desired by users, often missing important cleaning areas due to pre-programmed routes and requiring user intervention.

Innovation Solution

An artificial intelligence cleaner equipped with sensors like movement detect sensors, image sensors, and obstacle detectors that allow it to switch to a meticulous cleaning mode upon user intervention, detecting user movement and prioritizing cleaning based on sensed information.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Extent of automation

If the robot cleaner operates according to a pre-programmed cleaning route, then the cleaning process is automated and follows a predetermined path, but the user cannot prioritize specific areas that need cleaning first

Engineering Contradiction:
Improveautomation of cleaning routeVSAvoidability to prioritize cleaning areas
Core Design Contradiction:
Extent of automationVSAdaptability or versatility

Solution Approach 1:

The cleaning route is made dynamic by allowing real-time modifications based on user interaction. The system transitions from a static pre-programmed route to a dynamic route that adapts when the user moves the cleaner to a specific location, enabling priority area cleaning while maintaining overall automation

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system uses feedback from movement detection sensors to sense when the user relocates the cleaner. This feedback triggers a mode switch from general cleaning to meticulous cleaning, allowing the system to adapt its behavior based on user input while maintaining automated operation

Inventive Principle:
Principle #23Feedback

2Ease of operation

If the user manually moves the robot cleaner to a desired area using a remote controller, then the cleaner can reach the priority area, but the cleaner still follows the preset route and does not necessarily clean the desired area

Engineering Contradiction:
Improveuser ability to move cleaner to desired areaVSAvoidcleaning accuracy at desired area
Core Design Contradiction:
Ease of operationVSManufacturing precision

Solution Approach 1:

The system performs preliminary detection of user intent by detecting when the cleaner is moved from its automatic path. Upon detecting user manipulation, it proactively switches to meticulous cleaning mode at the new location, ensuring the area is actually cleaned rather than just reached

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The cleaning mode dynamically switches from general cleaning to meticulous cleaning based on user action. This dynamic adjustment ensures that when the user manually positions the cleaner, the system responds with appropriate intensive cleaning at that location

Inventive Principle:
Principle #15Dynamics

3Reliability

If the robot cleaner waits for the user to indicate a priority area, then it can potentially clean the desired area, but the user must wait for the cleaner to arrive at the area according to the preset route

Engineering Contradiction:
Improvecleaning of priority areaVSAvoiduser waiting time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The system performs preliminary detection of user intent through movement detection. When the user moves the cleaner, the system immediately recognizes this as a priority area indication and switches to meticulous cleaning mode, eliminating the need for the user to wait for the preset route to naturally bring the cleaner to that location

Inventive Principle:
Principle #10Preliminary action
