Innovation Solution

A modular apparatus for smoking article assembly that can be reconfigured to perform different sequences of operations, allowing a single machine to produce various cigarette configurations by rearranging modules, adding or removing components, and altering the order of operations.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If dedicated machinery is used for each cigarette configuration, then manufacturing precision and reliability are maintained, but device complexity and factory space requirements increase

Engineering Contradiction:
Improvemanufacturing reliabilityVSAvoidmachinery complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The cigarette manufacturing machine is divided into multiple independent modules, each performing a specific function (e.g., rod insertion, division, separation). These modules can be independently configured and rearranged to produce different cigarette types, reducing the need for entirely different machines while maintaining manufacturing reliability through specialized functional units.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The modular architecture enables a single machine to perform multiple functions by reconfiguring the same modules for different cigarette configurations. The same modular apparatus can produce various cigarette types by changing the arrangement and connection of modules, eliminating the need for dedicated machinery for each product variant.

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

2Manufacturing precision

If dedicated machinery is used for each cigarette configuration, then manufacturing precision is maintained, but loss of time and cost in product development increase

Engineering Contradiction:
Improveassembly precisionVSAvoidproduct development time
Core Design Contradiction:
Manufacturing precisionVSLoss of time

Solution Approach 1:

The modular modules are designed to be dynamically reconfigurable, allowing quick changes in their arrangement and connectivity to accommodate different cigarette configurations. This dynamic reconfiguration capability enables rapid product development without sacrificing assembly precision, as each module maintains its specialized function while adapting to new product requirements.

Inventive Principle:
Principle #15Dynamics

3Manufacturing precision

If dedicated machinery is used for each cigarette configuration, then manufacturing precision is maintained, but factory space requirements increase

Engineering Contradiction:
Improveassembly precisionVSAvoidfactory space
Core Design Contradiction:
Manufacturing precisionVSArea of stationary object

Solution Approach 1:

A single modular machine occupies factory space while being capable of producing multiple cigarette configurations through module reconfiguration. This universal machine replaces what would otherwise require multiple dedicated machines, significantly reducing the total factory space needed while maintaining the assembly precision of specialized equipment through its modular functional units.

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

4Adaptability or versatility

If modular reconfiguration is implemented, then adaptability and versatility improve, but device complexity increases

Engineering Contradiction:
Improveproduction flexibilityVSAvoidapparatus complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The apparatus is segmented into standardized modular units with defined interfaces and functions. This segmentation enables flexible reconfiguration for different production requirements while managing complexity through modular design principles, where each module remains relatively simple but the system as a whole achieves high versatility.

Inventive Principle:
Principle #1Segmentation

AI summary

A modular apparatus is configured to cause received rods of smokeable material to undergo a first sequence of operations. The modular apparatus can be reconfigured so as to cause received rods of smokeable material to undergo a second sequence of operations, different to the first sequence of operations. The first and second sequences of operations respectively form at least part of first and second processes for assembling smoking articles, each smoking article comprising one of said rods of smokeable material, which is smoked in use. The modular apparatus comprises a first inserter configured to insert a first rod article between two tobacco rods, a first rod divider configured to divide the first rod article into at least two parts, a separator configured to separate a first group comprising a rod of smokeable material and one of said parts from a second group comprising a rod of smokeable material and another of said parts and a second inserter configured to insert a second rod article between the first and second groups.
