Solution Overview

Problem

Existing machines for producing smoking articles with cavities are costly and time-intensive, particularly those used to form filter plugs with cavities, necessitating dedicated combiner machines.

Innovation Solution

A machine and method that integrate a picking, cutting, combining, and wrapping process to create smoking articles with cavities without a dedicated combiner, using separation means to form spaces between filter units and a second cutting assembly to define cavities, allowing for economical and simple production.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If a dedicated combiner machine is used to assemble filter rods with cavities, then the quality and precision of cavity formation is improved, but the device complexity and production cost increase

Engineering Contradiction:
Improvecavity formation precisionVSAvoidmachine structure complexity
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The patent combines the functions of filter rod assembly, cavity formation, and cigarette production into a single integrated machine. The combiner machine is merged with the cigarette making machine, allowing filter rods to be assembled and cavities to be formed within the same production line, eliminating the need for separate dedicated combiner equipment while maintaining production precision.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The cigarette making machine is designed to perform multiple functions: it assemblies filter rods, forms cavities, and produces cigarettes all in one process. This multi-functional approach allows the same machine to handle both standard and cavity-containing filter rods, providing versatility without requiring specialized equipment for each function.

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

2Manufacturing precision

If a dedicated combiner machine is used to form filter plugs with cavities, then the manufacturing precision of cavities is improved, but the productivity and production speed decrease

Engineering Contradiction:
Improvecavity formation precisionVSAvoidproduction speed
Core Design Contradiction:
Manufacturing precisionVSProductivity

Solution Approach 1:

By merging the cavity formation process with the main cigarette production line, the patent eliminates the need for separate combiner machines that would create bottlenecks. The integrated system allows continuous production where filter rods are assembled and cavities formed in-line, maintaining high production speeds without sacrificing cavity precision.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The machine prepares filter rods with cavities in advance during the assembly phase, before the actual cigarette making process begins. This preliminary formation of cavities ensures that when cigarettes are produced, the cavity-containing filter rods are already ready, eliminating post-processing steps and maintaining production efficiency.

Inventive Principle:
Principle #10Preliminary action

3Ease of manufacture

If existing machines are modified to produce smoking articles with cavities, then the ease of manufacture and cost-effectiveness are improved, but the manufacturing precision and reliability may be compromised

Engineering Contradiction:
Improvemodification simplicityVSAvoidcavity formation precision
Core Design Contradiction:
Ease of manufactureVSManufacturing precision

Solution Approach 1:

The modified machine is designed to handle both traditional and cavity-containing filter rods using the same basic mechanisms. The filter rod feeding system, cutting assembly, and wrapping unit are adapted to accommodate cavity formation without requiring completely new components, thus maintaining manufacturing precision while improving ease of manufacture and cost-effectiveness.

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