Solution Overview

Problem

Current packaging systems for disposable absorbent sanitary articles are limited by the need for two separate packaging machines to achieve high production speeds, leading to increased costs, space requirements, and limitations in package size due to the distance between extractor devices.

Innovation Solution

An apparatus that forms groups of products by using a conveyor system with orthogonally oriented septa and an extractor element to create groups, which are then compacted in series by dual compacting devices before being packaged, allowing for efficient packaging of up to 2000 products per minute with a single machine.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If a single packaging machine is used, then device complexity and cost are reduced, but production speed is limited due to extractor device spacing constraints

Engineering Contradiction:
Improvenumber of packaging machinesVSAvoidproduction speed
Core Design Contradiction:
Device complexityVSProductivity

Solution Approach 1:

The extraction system is segmented into multiple extraction stations arranged in series along the conveyor path, allowing each station to independently extract groups of products at different positions. This segmentation enables a single packaging machine to handle multiple extraction points simultaneously, increasing production speed without adding multiple complete packaging machines.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The invention transitions from a single extraction point to multiple extraction stations distributed along the conveyor's length (adding a spatial dimension). This dimensional expansion allows the system to process multiple groups of products in parallel through different extraction stations, effectively increasing throughput while maintaining a single packaging machine configuration.

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

2Productivity

If two packaging machines are used in parallel, then production speed increases, but device complexity, cost, and space requirements increase

Engineering Contradiction:
Improveproduction speedVSAvoidnumber of packaging machines
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

A single packaging machine is designed to perform multiple functions by serving multiple extraction stations. The packaging machine can simultaneously or sequentially package groups of products extracted at different stations, making it a multi-functional device that replaces what would traditionally require two separate machines.

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

Solution Approach 2:

The system maintains continuous operation by having multiple extraction stations feeding the packaging machine in sequence. While one extraction station is being serviced, another can be preparing the next group of products, ensuring continuous useful action without idle time and achieving high production speeds with a single machine.

Inventive Principle:
Principle #20Continuity of useful action

3Quantity of substance

If packages contain fewer products, then market demand is met, but production speed is limited by packaging machine capacity

Engineering Contradiction:
Improvenumber of products per packageVSAvoidproduction speed
Core Design Contradiction:
Quantity of substanceVSProductivity

Solution Approach 1:

The product flow is segmented into multiple groups at different extraction stations, each group destined for a package. This segmentation allows the system to handle smaller package sizes (meeting market demand) while processing multiple groups simultaneously through different stations, maintaining high production speed despite reduced products per package.

Inventive Principle:
Principle #1Segmentation
