Solution Overview

Problem

Existing sweeping robots require manual cleaning of their components such as mops and brushes after use, which is inconvenient and time-consuming for users.

Innovation Solution

A washing control method and apparatus for cleaning devices that allow them to automatically wash their cleaning assemblies by entering a charging pile with different postures, utilizing a washing assembly to perform washing tasks, and then exit and recharge, ensuring the cleaning device can autonomously maintain itself.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the cleaning device is equipped with automatic washing function, then the ease of operation is improved, but the device complexity increases

Engineering Contradiction:
Improveease of operationVSAvoiddevice complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The cleaning device automatically returns to the charging pile to wash its cleaning assembly (mop, brushes) without human intervention. The control system autonomously determines when washing is needed and executes the washing process, allowing the device to service itself and eliminating manual cleaning requirements for users.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The washing function is integrated into the charging pile structure. The charging pile combines charging functionality with washing capabilities, merging two separate functions (charging and cleaning) into a single stationary unit. This reduces the need for separate washing equipment and simplifies the overall system architecture.

Inventive Principle:
Principle #5Merging (Combining)

2Productivity

If the cleaning device performs multiple tasks autonomously, then the productivity is improved, but the device complexity increases

Engineering Contradiction:
ImproveproductivityVSAvoiddevice complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The cleaning device performs multiple functions: cleaning floors, automatic washing of its own components, and recharging. The charging pile also serves dual purposes: charging the device and providing washing services. This multi-functionality increases productivity by eliminating separate manual cleaning steps while the shared infrastructure (charging pile) helps manage system complexity.

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

3Adaptability or versatility

If the cleaning device enters charging pile with different postures, then the adaptability is improved, but the measurement precision requirements increase

Engineering Contradiction:
ImproveadaptabilityVSAvoidmeasurement precision
Core Design Contradiction:
Adaptability or versatilityVSMeasurement precision

Solution Approach 1:

The cleaning device is designed to enter the charging pile in different postures (orientations) depending on which cleaning assembly needs washing. The system dynamically adjusts the entry posture based on the washing requirements, allowing flexible adaptation to different cleaning scenarios while the control system manages the precision requirements for positioning.

Inventive Principle:
Principle #15Dynamics
