Solution Overview

Problem

Existing particle collection systems in the handicraft sector require frequent bag or filter replacements due to high particle contamination, leading to inefficiencies and increased maintenance costs.

Innovation Solution

A cyclone pre-separator and particle collection container arrangement where the particle collection container is designed to taper downwards, allowing for efficient stacking and space-saving transportation, eliminating the need for plastic bags and enhancing usability by enabling direct particle collection and easy handling.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If plastic bags are used in particle collection containers, then particle collection is effective, but the bags require frequent replacement due to high particle contamination

Engineering Contradiction:
Improveusability of bag or filter systemVSAvoidtime for bag replacement
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The cyclone pre-separator extracts the majority of particles from the air flow before it reaches the bag or filter. By removing particles in advance through cyclonic separation, the bag/filter system is protected from rapid contamination, extending its usability and reducing replacement frequency

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

Particle separation is performed in advance by the cyclone pre-separator before the air flow enters the bag filtration system. This preliminary action reduces the particle load on the bag, delaying the point at which it becomes saturated and requires replacement

Inventive Principle:
Principle #10Preliminary action

2Ease of operation

If multiple particle collection containers are transported separately, then each container is easy to handle, but transportation space efficiency is poor

Engineering Contradiction:
Improvehandling of particle collection containerVSAvoidtransportation space
Core Design Contradiction:
Ease of operationVSVolume of moving object

Solution Approach 1:

Particle collection containers are designed with a tapered shape that allows one container to be nested inside another identical container. This nesting capability enables multiple containers to be stacked vertically in a compact arrangement, dramatically improving transportation space efficiency while maintaining individual container handleability

Inventive Principle:
Principle #7Nested doll (Nesting)

Solution Approach 2:

The container design utilizes vertical stacking in the third dimension (height) rather than horizontal arrangement. By tapering the container shape to enable vertical nesting, the system transforms space utilization from a horizontal spread to a vertical stack, improving transportation efficiency without compromising individual container handling

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

3Reliability

If conventional particle collection containers are used, then particle collection is functional, but production costs are higher due to bag material requirements

Engineering Contradiction:
Improveparticle collection functionVSAvoidproduction cost
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

The invention replaces expensive reusable bags with a durable, injection-molded particle collection container that can be used repeatedly. The container design eliminates the need for disposable bag materials while maintaining effective particle collection functionality, reducing long-term production and operational costs

Inventive Principle:
Principle #27Cheap short-living objects (Disposable)

Solution Approach 2:

The container geometry is designed with specific parameters (tapered shape, opening dimensions) that enable both effective particle collection and space-efficient stacking. The material selection and structural parameters are optimized for durability and manufacturability through injection molding, reducing production costs compared to traditional bag-based systems

Inventive Principle:
Principle #35Parameter changes

AI summary

The invention relates to an assembly (30) comprising a particle collection container (2) and a cyclonic pre-separator (1) placed on the particle collection container (2). The particle collection container (2) has a rectangular container base (31) and four container peripheral walls (33, 34, 35, 36) which extend upwards from the container base (31) and define a horizontal outer contour of the particle collection container (2), and the cyclonic pre-separator (1) has a particle outlet (8) which is designed to dispense particles which have been separated in the cyclonic pre-separator (1) into the particle collection container (2). The horizontal outer contour defined by the container peripheral walls (33, 34, 35, 36) tapers towards the container base (31), and the particle collection container (2) can be stacked into an identical particle collection container (2).
