Solution Overview

Problem

Automatic cleaning apparatuses face issues with smooth entry and exit from self-cleaning dust collection seats due to rubbing or sticking, which affects their service life and operation efficiency.

Innovation Solution

A self-cleaning dust collection seat design featuring a bottom plate connected to a body base with a lifting structure at the edge of their joint, facilitating the automatic cleaning apparatus's backward movement and preventing sticking by pressing a cleaning module inward, thus allowing smooth docking and undocking.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the automatic cleaning apparatus moves on the bottom plate during entering or leaving the station, then the cleaning apparatus can enter/leave the station, but the bottom of the cleaning apparatus and the bottom plate rub against each other causing wear and potential sticking

Engineering Contradiction:
Improveentry and exit smoothnessVSAvoidservice life
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The bottom plate changes its surface morphology from a flat surface to an inclined plane with a specific angle range (5-15 degrees). This parameter change in the geometric configuration reduces friction and prevents sticking while maintaining smooth entry and exit operations. The inclined plane structure allows the cleaning apparatus to slide in and out more easily without excessive rubbing against the bottom plate.

Inventive Principle:
Principle #35Parameter changes

2Ease of operation

If the cleaning module is located on the bottom surface of the automatic cleaning apparatus, then the cleaning module can contact the bottom plate for cleaning, but the cleaning module may get stuck between the bottom plate and the cleaning apparatus body during entering or leaving

Engineering Contradiction:
Improveentry and exit smoothnessVSAvoidservice life
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The lifting structure is positioned at the edge of the joint between the body base and bottom plate to preemptively lift the cleaning module before the cleaning apparatus enters the station. This preliminary action prevents the cleaning module from being pinched or stuck between the bottom plate and the apparatus body during entry, eliminating the harmful effect before it can occur.

Inventive Principle:
Principle #9Preliminary anti-action

Solution Approach 2:

The lifting structure performs the action of lifting the cleaning module in advance during the entry process. By lifting the cleaning module before the apparatus fully enters the station, the system prepares the cleaning module for its final position, preventing it from getting stuck and ensuring smooth operation.

Inventive Principle:
Principle #10Preliminary action

3Reliability

If the lifting structure presses the cleaning module inward during backward movement, then the cleaning module moves toward the interior preventing sticking, but this requires additional mechanical structure and control

Engineering Contradiction:
Improveservice lifeVSAvoidstructure complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The lifting structure is designed to automatically activate when the cleaning apparatus enters the station. The system uses the entry motion itself to trigger the lifting action, eliminating the need for separate complex control mechanisms. The cleaning module serves its dual purpose of both cleaning and being lifted into position, reducing overall system complexity.

Inventive Principle:
Principle #25Self-service
