Solution Overview

Problem

Conventional smoking articles with integrated extinguisher elements for tobacco rods are complex to manufacture, as the connected reservoir and elongate tube are difficult to incorporate using conventional assembly techniques, requiring significant modifications to existing high-speed manufacturing machines and processes.

Innovation Solution

A smoking article design featuring a compressible reservoir with a neck portion and sealing means, where the neck portion is supported within a tubular element, allowing for efficient liquid delivery directly into the tobacco rod upon compression, enabling controlled extinguishment without damaging the components during assembly.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a connected reservoir and elongate tube are incorporated into the smoking article, then liquid delivery to the burning end is achieved, but the manufacturing complexity increases significantly

Engineering Contradiction:
Improveliquid deliveryVSAvoidmanufacturing complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The extinguisher element is divided into separate functional components: a reservoir for liquid storage, a neck portion for liquid delivery, and sealing means for controlled release. This segmentation allows each component to be manufactured and assembled independently, reducing overall manufacturing complexity while maintaining reliable liquid delivery functionality.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The neck portion is received within the longitudinal channel of the tubular element, creating a nested arrangement. The reservoir is positioned within the cavity defined by the tubular element and downstream filter segment. This nesting allows multiple components to be integrated into a compact structure that can be manufactured using conventional assembly techniques without significant modifications to existing high-speed manufacturing machines.

Inventive Principle:
Principle #7Nested doll (Nesting)

2Reliability

If the reservoir and elongate tube extend between the filter and tobacco rod, then effective extinguishment is achieved, but the assembly becomes difficult to insert into the smoking article

Engineering Contradiction:
Improveextinguishment effectivenessVSAvoidassembly difficulty
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

The extinguisher element is segmented into distinct components (reservoir, neck portion, sealing means) that can be assembled separately and then integrated into the smoking article. This segmentation simplifies the assembly process compared to inserting a single complex connected reservoir-and-tube assembly, while still achieving effective extinguishment through the coordinated function of these segmented components.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The tubular element serves as an intermediary structure that receives and protects the neck portion during assembly. The cavity formed between the tubular element and downstream filter segment provides a designated space for the reservoir. These intermediary structures facilitate the insertion and assembly of the extinguisher components without requiring significant modifications to existing manufacturing processes.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Productivity

If conventional assembly apparatus and techniques are used, then manufacturing efficiency is maintained, but the connected reservoir and elongate tube cannot be incorporated

Engineering Contradiction:
Improvemanufacturing efficiencyVSAvoidcomponent integration
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

By segmenting the extinguisher system into separate components (reservoir, neck portion, sealing means) that can be assembled independently, the design maintains compatibility with conventional assembly apparatus and techniques. Each component can be manufactured and prepared separately, then quickly assembled using existing high-speed manufacturing equipment, thereby maintaining manufacturing efficiency while achieving the required component integration.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The nested arrangement of the neck portion within the tubular element's longitudinal channel and the reservoir within the cavity creates a compact integrated structure. This nesting allows the extinguisher element to be assembled as a unified component that can be efficiently integrated into the smoking article using conventional assembly techniques, maintaining manufacturing efficiency without requiring complex specialized equipment.

Inventive Principle:
Principle #7Nested doll (Nesting)

Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

Function Achieved in This Case

This design allows for efficient and controlled extinguishment of the tobacco rod with minimal modification to existing manufacturing processes, ensuring effective liquid delivery and protecting the assembly components during production.

Implementation Method 1

Upon compression of the reservoir during use, the sealing means over the open end of the neck portion are broken and the liquid from the reservoir is releasable through the neck portion directly into the tobacco rod

AI summary

A smoking article (10) includes a tobacco rod (“rod”) (12) and a mouthpiece (14) secured to a downstream end of the rod (12). The mouthpiece contains: a tubular element (20) defining a longitudinal channel, a downstream segment of filter material (24), and an extinguisher element (22). The tubular element (20) is provided adjacent the downstream end of the rod (12). The downstream segment of filter material (24) is downstream of the tubular element (20) and spaced apart from the tubular element (20) to define a cavity (26) between the tubular element (20) and the downstream segment of filter material (24). The extinguisher element (22) includes: a compressible reservoir (28) provided in the cavity (26) and containing liquid, a neck portion (30) extending upstream from the reservoir (28) and having an open end, and a seal (32) provided over the open end of the neck portion (30). The neck portion (30) is received in the longitudinal channel of the tubular element (20) such that the open end is proximate the downstream end of the rod (12).
