Solution Overview

Problem

Conventional cleaning robots lack intuitive state display and user interface capabilities, making it difficult for users to monitor and control their operations, especially in divided regions with varying obstacle arrangements.

Innovation Solution

A cleaning robot equipped with a user interface that displays a map image of divided regions, showing the robot's state through icons and animations, and allows users to set target points and virtual walls, enabling intuitive control and navigation within selected areas.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If the cleaning robot operates autonomously without user manipulation, then productivity is improved, but the user cannot check the state of the cleaning robot, worsening information availability

Engineering Contradiction:
Improveautonomous cleaning operationVSAvoiduser awareness of robot state
Core Design Contradiction:
ProductivityVSLoss of information

Solution Approach 1:

The patent implements a feedback mechanism by displaying the cleaning robot's current position, state, and cleaning progress on a user terminal device. The controller transmits position information and state data (cleaning, charging, error states) to the terminal, allowing users to monitor the autonomous operation in real-time without interfering with productivity

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The user terminal device serves as an intermediary between the cleaning robot and the user. It receives position and state information from the robot's controller and presents it in an intuitive format (map display with icons and animations), bridging the information gap while maintaining autonomous operation

Inventive Principle:
Principle #24Intermediary (Mediator)

2Loss of information

If the user directly controls the cleaning robot position using a remote controller, then the user can check and control the robot position, but ease of operation deteriorates due to manual intervention requirements

Engineering Contradiction:
Improveuser awareness of robot positionVSAvoidmanual position control
Core Design Contradiction:
Loss of informationVSEase of operation

Solution Approach 1:

The cleaning robot performs self-navigation and self-positioning using its sensors and map data. The user simply designates a target region on the displayed map, and the robot autonomously determines its own path and executes the cleaning task without requiring continuous manual guidance, significantly improving ease of operation

Inventive Principle:
Principle #25Self-service

3Productivity

If the cleaning robot cleans the entire space without region division, then productivity is maintained, but adaptability worsens when obstacle arrangements vary in divided regions

Engineering Contradiction:
Improveoverall cleaning efficiencyVSAvoidhandling of varied obstacle arrangements in divided regions
Core Design Contradiction:
ProductivityVSAdaptability or versatility

Solution Approach 1:

The cleaning space is segmented into multiple virtual regions based on map data and obstacle information. The controller divides the cleaning task into region-specific sub-tasks, allowing the robot to adapt its cleaning path and strategy to the specific obstacle arrangements in each region while maintaining overall cleaning productivity

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent applies local quality by customizing the cleaning approach for each divided region according to its specific characteristics (obstacle density, size, shape). The robot adjusts its navigation and cleaning parameters locally for each region rather than using a uniform approach, improving adaptability to varied obstacle arrangements

Inventive Principle:
Principle #3Local quality

4Loss of information

If the user interface displays detailed real-time information, then information availability is improved, but device complexity increases

Engineering Contradiction:
Improvedetailed robot state informationVSAvoiduser interface complexity
Core Design Contradiction:
Loss of informationVSDevice complexity

Solution Approach 1:

The user terminal displays a simplified copy or representation of the cleaning space as a virtual map, with the robot's position and state represented by icons and animations. This graphical copy provides comprehensive information about robot location, cleaning progress, and status without requiring complex data presentations, maintaining interface simplicity while improving information availability

Inventive Principle:
Principle #26Copying
