Solution Overview

Problem

Existing manufacturing machines for multi-segment smoking articles require significant space due to separate feed modules for each segment, especially when producing products with multiple identical segments, leading to increased space requirements and inefficiencies.

Innovation Solution

A method and machine design that uses a single filter rod or two identical filter rods to produce filter segments of different lengths, allowing for the assembly of rod-shaped smoking articles with a mouth-side and distal filter segment without the need for separate feed modules for each segment, utilizing a reorientation unit and wrapping modules to efficiently manage segment lengths and assembly.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If separate feeding modules are provided for each segment, then each segment can be supplied and cut independently, but the machine's space requirement increases significantly

Engineering Contradiction:
Improvesegment supply flexibilityVSAvoidmachine space requirement
Core Design Contradiction:
Adaptability or versatilityVSArea of stationary object

Solution Approach 1:

A single feeding module is designed to handle multiple segment types by selectively supplying different filter rods (e.g., filter rod AB for filter segment A, filter rod BC for filter segment B) based on the required segment configuration. This multi-functional feeding module eliminates the need for separate dedicated feeding modules for each segment type, thereby reducing machine space while maintaining supply flexibility.

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

Solution Approach 2:

The filter rod is divided into different segments (filter segment A, filter segment B) with specific lengths and functions. The feeding module supplies complete filter rods that are then cut into appropriate segments, allowing flexible combination of different segment types in a single production line without requiring separate feeding mechanisms for each segment.

Inventive Principle:
Principle #1Segmentation

2Adaptability or versatility

If multiple identically shaped segments are produced from identically shaped filter rods, then production variability is maintained, but the machine's space requirement increases due to separate feeding modules for each additional segment

Engineering Contradiction:
Improvesegment configuration flexibilityVSAvoidmachine footprint
Core Design Contradiction:
Adaptability or versatilityVSArea of stationary object

Solution Approach 1:

The feeding module is designed to supply different filter rods (AB1, AB2) that can be cut into various segment configurations. This single multi-functional feeding module replaces multiple dedicated feeding modules, enabling production of different segment combinations (e.g., A+A, A+B, B+B) without increasing machine space.

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

Solution Approach 2:

The system maintains production variability by changing parameters such as filter rod length, segment length, and segment type rather than requiring separate physical feeding modules for each configuration. The feeding module supplies filter rods with different lengths or types that are then cut into the required segment configurations, achieving flexibility through parameter variation rather than structural duplication.

Inventive Principle:
Principle #35Parameter changes

3Manufacturing precision

If filter rods are cut into segments of different lengths, then segment length requirements are met, but residual segments may be generated requiring removal

Engineering Contradiction:
Improvesegment length accuracyVSAvoidresidual segment waste
Core Design Contradiction:
Manufacturing precisionVSLoss of substance

Solution Approach 1:

The feeding module supplies filter rods with lengths that are pre-calculated to match the required segment lengths. For example, if filter segment A requires length L_a and filter segment B requires length L_b, the system supplies filter rods with lengths that are exact multiples of these segment lengths (e.g., 2*L_a, 2*L_b, or combinations), ensuring that complete segments can be produced without generating residual waste that would need removal.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system adjusts filter rod length parameters to match segment requirements. By varying the filter rod length supplied to the cutting device based on the specific segment configuration needed, the system achieves precise segment lengths without waste. The feeding module coordinates with the cutting device to ensure the filter rod length is optimized for the intended segment division.

Inventive Principle:
Principle #35Parameter changes

AI summary

Method and machine for manufacturing a rod-shaped smoking article (10) with a mouth-side end and an upstream distal end, wherein the smoking article has several segments (20, 30, 40, 50, 90), wherein at least one segment (20) comprises aerosol-forming substrate, in particular reconstituted tobacco, and the segments comprise at least one filter segment A (90) and one filter segment B (50), wherein the filter segment A is arranged upstream of the aerosol-forming substrate and the filter segment B is arranged downstream of the aerosol-forming substrate to provide a smoking article with a protective segment at the distal end, wherein the segment at the mouth-side end and the segment at the distal end are made from similarly shaped filter rods or the same filter rod.
