Solution Overview

Problem

Existing map displays for sweeping robots only show room boundaries and lack detailed representation of carpeted regions, making it difficult for users to accurately control and clean specific areas.

Innovation Solution

A method and device for acquiring and displaying room and region map data, where a region map layer is drawn on the room map based on region map data, allowing users to visualize and control cleaned regions more effectively.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If only room boundary outline is displayed on the map, then the map display is simple and clear, but the user cannot accurately locate and control cleaned regions in carpeted areas

Engineering Contradiction:
Improvelocation accuracy of cleaned regionsVSAvoidmap display complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The map display is segmented into multiple layers: a room map layer showing the overall room boundary and a region map layer showing detailed carpeted regions. This allows the system to provide detailed information about cleaned regions without cluttering the entire map display, thereby improving location accuracy while maintaining manageable complexity through modular layer structure.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent introduces a vertical dimension by stacking map layers. The room map and region map are displayed as separate layers that can be overlaid or switched between, transforming a two-dimensional flat map into a multi-layered structure. This enables detailed region information to be presented without increasing horizontal complexity.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Ease of operation

If a region map layer is drawn on the room map to show carpeted regions, then users can accurately control cleaned regions, but the map display complexity increases

Engineering Contradiction:
Improveuser control capabilityVSAvoidmap processing complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The map display system is designed to be dynamic, allowing users to switch between different map layers (room map only, region map only, or both overlaid). The system can dynamically adjust which layer is displayed based on user needs, providing ease of operation while managing complexity through flexible, on-demand layer rendering rather than permanently displaying all layers simultaneously.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent introduces a map rendering module as an intermediary that processes and manages multiple map layers. This intermediary component handles the complexity of layer integration, coordinate transformation, and display management, thereby simplifying the user interface and improving ease of operation while containing processing complexity within a dedicated module.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Manufacturing precision

If the sub-region is magnified by a preset scale to draw region map data, then the region map layer is more detailed, but the processing time and computational resources increase

Engineering Contradiction:
Improveregion map drawing precisionVSAvoidmap rendering time
Core Design Contradiction:
Manufacturing precisionVSLoss of time

Solution Approach 1:

The patent applies magnification selectively only to the sub-region containing carpeted areas, not to the entire room map. This local quality approach ensures that detailed region map data is rendered with high precision where needed, while other areas maintain their original scale, thereby reducing overall processing time and computational resources compared to magnifying the entire map.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The system performs partial magnification only on the necessary sub-region rather than the entire map. This partial action principle allows the patent to achieve sufficient drawing precision for carpeted regions without the excessive computational cost of magnifying or processing the entire room map at high resolution.

Inventive Principle:
Principle #16Partial or excessive action
