Solution Overview

Problem

Existing cleaning robots face safety hazards due to separation of adsorption members caused by collisions with foreign objects, leading to potential damage or loss of safety protection functionality.

Innovation Solution

A multi-medium intelligent cleaning apparatus with a self-propelled robot and a safety protection apparatus connected via a connecting member, featuring an anti-collision member that protrudes from the adsorption member to prevent foreign object impacts, along with sensors and a control module to manage collision forces and prevent separation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If the adsorption member and robot are located on the same working surface, then the robot can clean the surface, but the robot may collide with the adsorption member causing separation and safety hazards

Engineering Contradiction:
Improvecleaning capabilityVSAvoidsafety protection
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The system divides the working surface into distinct zones: the robot operates on the cleaning surface while the adsorption member is positioned on a separate safety surface, physically segmenting their operational spaces to prevent collision while maintaining functional independence

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The adsorption member is relocated from the same two-dimensional working surface to a different spatial plane (safety surface), adding a dimensional separation that eliminates collision risk while preserving the robot's cleaning path

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

2Reliability

If the adsorption member and robot are located on different adsorption surfaces, then collision is avoided, but foreign objects may still impact the adsorption member causing it to fall

Engineering Contradiction:
Improvecollision avoidanceVSAvoidforeign object impact
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The anti-collision member is pre-installed on the adsorption member to provide preliminary protection against foreign object impacts before such impacts can occur, creating a preventive barrier that counteracts potential harmful forces

Inventive Principle:
Principle #9Preliminary anti-action

Solution Approach 2:

The anti-collision member serves as a cushioning element positioned in advance to absorb and distribute impact forces from foreign objects, preventing these forces from reaching the adsorption member and causing detachment

Inventive Principle:
Principle #11Beforehand cushioning (Prior cushioning)

3Object-affected harmful factors

If the anti-collision member protrudes from the adsorption member, then foreign object impact is prevented, but the structure becomes more complex

Engineering Contradiction:
Improveimpact protectionVSAvoidstructural complexity
Core Design Contradiction:
Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

Instead of making the entire adsorption member complex, only a specific local region (the protruding anti-collision member) is modified to provide protection, concentrating the structural enhancement where it is most needed while keeping the rest of the system simple

Inventive Principle:
Principle #3Local quality

AI summary

Provided are a multi-medium intelligent cleaning apparatus and a control method. The multi-medium intelligent cleaning apparatus is used for cleaning a working surface, and includes a self-propelled cleaning robot (1) and a safety protection apparatus connected to the self-propelled cleaning robot (1) through a connecting member (3). The safety protection apparatus includes an adsorption member (2) for adsorbing on a surface to be adsorbed. The multi-medium intelligent cleaning apparatus further includes an anti-collision member (4) arranged on the adsorption member (2). The anti-collision member (4) protrudes from an outer end edge of the adsorption member (2) so as to prevent a foreign object from impacting the adsorption member (2). According to the anti-collision member (4) arranged on the adsorption member (4), the possibility that the adsorption member (2) falls off due to impact of a foreign object is reduced.
