Solution Overview

Problem

Existing cleaning robot systems face challenges in efficiently dividing and managing cleaning zones among multiple robots, leading to prolonged cleaning times and inefficient collaborative cleaning within a shared space.

Innovation Solution

A collaborative cleaning system that assigns individual cleaning regions to robots based on their location information, using processors to map and merge location data, and prioritize cleaning tasks, allowing robots to communicate and adjust their cleaning paths dynamically.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If multiple cleaning robots are deployed to clean a large cleaning zone, then the cleaning coverage and productivity are improved, but the coordination complexity and time management become more difficult

Engineering Contradiction:
Improvecleaning coverageVSAvoidcoordination complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The cleaning zone is divided into multiple sub-zones, and each cleaning robot is assigned to a specific sub-zone based on its location. This segmentation allows multiple robots to work simultaneously without complex coordination, as each robot independently cleans its designated area. The processor automatically determines the cleaning sub-zone for each robot, simplifying the division of labor.

Inventive Principle:
Principle #1Segmentation

2Productivity

If multiple cleaning robots operate in the same cleaning zone, then the cleaning productivity increases, but the cleaning time management and collision avoidance become more challenging

Engineering Contradiction:
Improvecleaning efficiencyVSAvoidcleaning time
Core Design Contradiction:
ProductivityVSLoss of time

Solution Approach 1:

Before the cleaning operation begins, the processor pre-determines the cleaning sub-zone for each cleaning robot based on its initial location. This preliminary assignment of zones prevents robots from entering each other's paths, eliminating the need for real-time collision avoidance and ensuring efficient time management. Each robot knows its designated area in advance, preventing redundant cleaning and optimizing the overall cleaning time.

Inventive Principle:
Principle #10Preliminary action

3Ease of operation

If cleaning robots autonomously determine their cleaning paths, then the ease of operation is improved, but the measurement precision of location and path planning becomes more critical

Engineering Contradiction:
Improveautonomous operationVSAvoidlocation identification accuracy
Core Design Contradiction:
Ease of operationVSMeasurement precision

Solution Approach 1:

The processor acts as an intermediary that receives location information from cleaning robots and determines their assigned cleaning sub-zones. Instead of requiring robots to independently calculate complex paths with high precision, the processor simplifies the task by assigning specific sub-zones based on robot locations. This intermediary step reduces the measurement precision requirements for individual robots while maintaining autonomous operation.

Inventive Principle:
Principle #24Intermediary (Mediator)
