Solution Overview

Problem

Existing methods for producing rod-shaped articles in the tobacco processing industry lack the ability to efficiently and variably combine multiple types of segments, particularly filter segments, which can lead to issues during the transfer from transverse-axial to longitudinal-axial conveying directions.

Innovation Solution

A method where segments of different types are alternately arranged in a row transversely, with specific spacing, allowing for the introduction of at least three different segment types, and then conveyed longitudinally to form rod-shaped articles, enabling precise and reliable assembly of multi-segment filters with various configurations.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple types of filter segments are combined in a row during transverse-axial conveying, then the variety of rod-shaped articles that can be produced increases, but the length of segment groups increases causing transfer problems to longitudinal-axial conveying

Engineering Contradiction:
Improvevariety of rod-shaped articlesVSAvoidlength of segment groups
Core Design Contradiction:
Adaptability or versatilityVSLength of moving object

Solution Approach 1:

The conveying process is divided into two distinct directional phases: transverse-axial conveying for assembling segments laterally, and longitudinal-axial conveying for transferring the completed groups. This segmentation of the conveying process allows segments to be arranged in variety-rich configurations during transverse conveying without creating transfer problems, as the longitudinal conveying phase handles the actual transfer of completed, manageable-length groups to the final product position

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The invention utilizes a two-dimensional assembly approach during transverse-axial conveying, where segments of different types are arranged both laterally across the conveying direction and in sequences along it. This dimensional arrangement allows for high variety in the final rod-shaped articles while maintaining control over group lengths, as segments can be distributed across multiple positions rather than simply extended in a single long line

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

2Adaptability or versatility

If the distance between segments of the first type is increased to accommodate more segment types, then more segment types can be introduced, but the transverse axial distance required increases

Engineering Contradiction:
Improvenumber of segment typesVSAvoidtransverse axial distance
Core Design Contradiction:
Adaptability or versatilityVSArea of stationary object

Solution Approach 1:

Multiple types of segments are nested within the transverse-axial conveying sequence by introducing segments of second, third, and fourth types in alternating patterns between segments of the first type. This nesting approach allows many different segment types to be incorporated into the assembly without requiring proportionally large increases in transverse distance, as segments are efficiently packed into the available conveying space through systematic alternation patterns

Inventive Principle:
Principle #7Nested doll (Nesting)
