Problem

Autonomous cleaning robots face inefficiencies due to the need for continuous human guidance and manual intervention for debris bin emptying, leading to downtime and potential operational errors in evacuation stations.

Innovation Solution

A system comprising an autonomous cleaning robot that interfaces with an evacuation station for automatic debris bin emptying, featuring a mobile application for remote monitoring and control, an indicator for status updates, and a transceiver for communication, enabling efficient operation and error detection.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If manual intervention is used for debris bin emptying, then the evacuation station can be simple in structure, but the robot experiences downtime and requires continuous human guidance

Engineering Contradiction:
Improverobot cleaning efficiencyVSAvoidevacuation station complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The evacuation station automatically detects when the robot's debris bin is full and initiates the emptying process without human intervention. The system self-manages the evacuation operation, allowing the robot to continue cleaning autonomously and eliminating downtime associated with manual bin emptying.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The evacuation station uses sensors to monitor the robot's debris bin status and receives feedback about bin fullness. Based on this feedback, the system automatically triggers the evacuation process, creating a closed-loop control system that eliminates the need for continuous human monitoring and intervention.

Inventive Principle:
Principle #23Feedback

2Extent of automation

If automatic evacuation is implemented, then the robot can operate autonomously without continuous human guidance, but the evacuation station requires complex control systems and communication interfaces

Engineering Contradiction:
Improveautonomous operation capabilityVSAvoidcontrol system complexity
Core Design Contradiction:
Extent of automationVSDevice complexity

Solution Approach 1:

The evacuation station integrates multiple functions into a single system: debris detection, automated evacuation, status monitoring, and user notification. This multi-functional design consolidates what would otherwise require separate systems, achieving high automation while managing complexity through functional integration.

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

Solution Approach 2:

The system uses a mobile device application as an intermediary between the evacuation station and the user. This intermediary provides a user-friendly interface for monitoring and controlling the automated system without requiring the user to directly interact with complex control systems, thus enabling autonomous operation while simplifying user interaction.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Loss of information

If the evacuation station provides real-time status monitoring, then the user can remotely monitor and control the robot, but the communication system becomes more complex

Engineering Contradiction:
Improvestatus information availabilityVSAvoidcommunication system complexity
Core Design Contradiction:
Loss of informationVSDevice complexity

Solution Approach 1:

The system creates a digital copy or representation of the physical evacuation station and robot status on the mobile device. Instead of requiring direct interaction with the physical system, the user interacts with a digital interface that mirrors the real-time status, enabling remote monitoring and control while keeping the physical communication system relatively simple.

Inventive Principle:
Principle #26Copying
