Solution Overview

Problem

Existing systems for cleaning environments with autonomous cleaning devices require manual intervention for tasks like emptying wastebaskets and refilling consumables, which are not efficiently automated, leading to suboptimal distribution of work tasks.

Innovation Solution

A system with a computing device that analyzes environmental parameters and operating statuses to create a work plan, distinguishing between activities that can be automatically executed by cleaning devices and those requiring manual intervention, and automatically prioritizing and scheduling tasks based on urgency and capability.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Extent of automation

If manual intervention is used for tasks like emptying wastebaskets and refilling consumables, then flexibility and adaptability are maintained, but productivity and automation extent are reduced

Engineering Contradiction:
Improveautomation of cleaning tasksVSAvoidmanual intervention capability
Core Design Contradiction:
Extent of automationVSAdaptability or versatility

Solution Approach 1:

The cleaning device is equipped with a detachable container that can be automatically emptied at a base station or docking station. The system autonomously performs the emptying operation without requiring manual intervention, while still allowing manual override when needed. This enables self-service automation while preserving adaptability for manual tasks.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The cleaning system is divided into modular components including a detachable container, base station, and control unit. This segmentation allows the container to be automatically emptied at the base station while maintaining the option for manual emptying, thus achieving both automation and adaptability through modular design.

Inventive Principle:
Principle #1Segmentation

2Productivity

If all work activities are automatically executed by cleaning devices, then productivity increases, but device complexity and operational limitations worsen

Engineering Contradiction:
Improvecleaning task execution efficiencyVSAvoidsystem configuration complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The system implements partial automation where only suitable cleaning tasks are automatically executed by the cleaning device, while tasks requiring manual intervention are identified and assigned to users. The computer distinguishes between automatically executable tasks and manually required tasks, avoiding the complexity of making the device capable of all possible tasks.

Inventive Principle:
Principle #16Partial or excessive action

Solution Approach 2:

A computer system acts as an intermediary between the cleaning device and the user. It receives work orders, determines which tasks can be automatically executed versus which require manual intervention, and coordinates the execution. This intermediary manages the complexity centrally rather than requiring the cleaning device itself to handle all task types.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Productivity

If manual decision-making is required for task distribution, then adaptability to specific situations is maintained, but loss of time and productivity decrease

Engineering Contradiction:
Improvetask distribution efficiencyVSAvoidmanual planning time
Core Design Contradiction:
ProductivityVSLoss of time

Solution Approach 1:

The system uses feedback from environmental detection devices and status detection devices to automatically determine task distribution. The computer receives real-time information about the cleaning device's status, environmental conditions, and completed tasks, and uses this feedback to dynamically assign new tasks without manual intervention, thus eliminating time loss while maintaining adaptability.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The computer pre-determines the distribution of work activities based on received work orders and current system status before execution begins. By performing the task allocation decision in advance automatically, the system eliminates the time that would otherwise be spent on manual task distribution planning.

Inventive Principle:
Principle #10Preliminary action
