Solution Overview

Problem

Existing cleaning device methods lack user flexibility and control over defining and assigning cleaning tasks to specific surface areas, as subareas are automatically defined without user intervention.

Innovation Solution

Users can manually define the position, shape, and size of partial surface areas on a map and specify cleaning tasks, including intensity and frequency, with the cleaning device detecting soiling levels and adjusting operations accordingly.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If subareas are automatically defined by the control device without user intervention, then the device complexity is reduced and ease of operation is improved, but the adaptability and user control over cleaning strategies are worsened

Engineering Contradiction:
Improveease of operationVSAvoidadaptability
Core Design Contradiction:
Ease of operationVSAdaptability or versatility

Solution Approach 1:

A map display interface serves as an intermediary between the automatic detection system and the user, allowing users to visually review automatically detected subareas and manually adjust their definitions, shapes, and cleaning task assignments without directly interacting with the control device's programming functions

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The system transitions from static automatic definition to dynamic user-adjustable definitions, where subarea parameters (position, shape, size, cleaning intensity) can be modified in real-time based on user input and soiling level observations

Inventive Principle:
Principle #15Dynamics

2Adaptability or versatility

If users manually define position, shape, and size of partial surface areas, then the adaptability and user control are improved, but the ease of operation and device complexity are worsened

Engineering Contradiction:
Improveuser controlVSAvoiddevice complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The system creates a visual copy (map) of the physical environment where users can define and adjust subarea parameters. This graphical interface simplifies the complexity by providing an intuitive visual representation rather than requiring direct manipulation of coordinate systems or technical parameters

Inventive Principle:
Principle #26Copying

Solution Approach 2:

The control device automatically detects and pre-defines subareas and their basic parameters before presenting them to the user for confirmation or modification, reducing the user's workload while maintaining adaptability

Inventive Principle:
Principle #10Preliminary action

3Productivity

If cleaning intensity is automatically adjusted based on detected soiling levels, then the productivity is improved, but the user control and adaptability to specific surface requirements are worsened

Engineering Contradiction:
ImproveproductivityVSAvoiduser control
Core Design Contradiction:
ProductivityVSAdaptability or versatility

Solution Approach 1:

The system implements a feedback loop where the detection device provides real-time information about soiling levels to the control device, which then automatically adjusts cleaning intensity parameters. This closed-loop control enables adaptive productivity optimization while maintaining user oversight through the map interface

Inventive Principle:
Principle #23Feedback

AI summary

The application relates to a method for operating a self-propelled cleaning device (1) within an environment, wherein the cleaning device (1) cleans an area (2) according to a predefined work plan, determining at least one degree of soiling of the area (2) and controlling a cleaning task depending on the degree of soiling. To make the cleaning operation more flexible and individualized, it is proposed that the degree of soiling be entered into a map (4) linked to positional information of the environment, wherein a user edits the map (4), namely by defining area sub-areas (5, 6, 7, 8) of the area (2) in the map (4) and manually assigning a cleaning task of the cleaning device (1) to at least one area sub-area (5, 6, 7, 8).
