Solution Overview

Problem

Existing mobile suction devices face challenges in handling particle collection containers, as they are often cumbersome and difficult to manage, especially when stacked, which complicates transportation and storage.

Innovation Solution

A mobile suction device with a container receptacle on its upper side that accommodates particle collection containers with a downwardly tapering outer contour, allowing for horizontal stabilization and easy stacking, along with detachable coupling mechanisms for the cyclone pre-separator and system boxes, enabling stable and practical handling and transportation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If traditional particle collection containers are used, then they can collect particles effectively, but they are cumbersome and difficult to handle when stacked

Engineering Contradiction:
Improveease of handling particle collection containersVSAvoidcomplexity of container stacking arrangement
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The particle collection container is designed with a downwardly tapering outer contour that allows it to be nested within another identical container. The container receptacle on the mobile suction device provides a tapered receiving space that guides and stabilizes the nested container horizontally, enabling compact stacking and easier handling without complex mechanisms.

Inventive Principle:
Principle #7Nested doll (Nesting)

2Adaptability or versatility

If the particle collection container has a downwardly tapered outer contour for stacking, then it can be stacked inside another container, but it requires a specially designed container receptacle with tapered inner contour

Engineering Contradiction:
Improvestackability of particle collection containersVSAvoidcomplexity of container receptacle design
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The container receptacle features an asymmetric tapered inner contour that corresponds to the downwardly tapered outer contour of the particle collection container. This asymmetric design provides horizontal stabilization and guidance while enabling the container to be stacked inside another identical container, achieving versatility without excessive complexity.

Inventive Principle:
Principle #4Asymmetry

3Stability of the object's composition

If the container receptacle has steep lateral inner sides for stabilizing the container, then it provides good stability during inclined use, but it reduces the vertical space available in the receptacle

Engineering Contradiction:
Improvestability of particle collection container during inclined useVSAvoidvertical space in container receptacle
Core Design Contradiction:
Stability of the object's compositionVSVolume of moving object

Solution Approach 1:

The container receptacle is designed with steep lateral inner sides that taper towards the base, creating a snug fit for the particle collection container. This geometric parameter change provides excellent stability during inclined use by preventing lateral movement, while the tapering design efficiently utilizes the vertical space available in the receptacle.

Inventive Principle:
Principle #35Parameter changes
