Solution Overview

Problem

Aerosol generating systems face challenges in manufacturing complexity and cost due to the need for precise engineering of piercing members, which can fail after multiple uses and pose risks to consumers.

Innovation Solution

A compact aerosol-generating system with a rupturing system comprising two tubes that move relative to each other, containing a rupturing member that protrudes only when needed to pierce the container, reducing manufacturing complexity and risk of injury.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a stationary exposed piercing element is used, then the piercing function is simple, but the risk of breaking off and injury to consumer increases

Engineering Contradiction:
Improvepiercing operationVSAvoidrisk of injury
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The rupturing member is extracted from a stationary position and integrated into a movable tube system, allowing it to be enclosed during storage and only exposed when the tube moves to the second position to perform the piercing function

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The rupturing member is nested inside the tube, specifically contained within the volume defined by the first and second tubes in the first position, and only protrudes when the tube moves to the second position

Inventive Principle:
Principle #7Nested doll (Nesting)

2Reliability

If a precise piercing member is engineered, then the piercing reliability is improved, but the manufacturing complexity and costs increase

Engineering Contradiction:
Improvepiercing reliabilityVSAvoidmanufacturing complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The system transitions from a static piercing element to a dynamic tube system that moves between positions, allowing the rupturing member to be enclosed during storage and only exposed when needed, simplifying the overall design while maintaining reliability

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The tube system is pre-configured with the rupturing member in an enclosed state, and the movement to the second position is the triggering action that exposes the rupturing member only when needed, preventing premature exposure or breakage

Inventive Principle:
Principle #10Preliminary action

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

The system is cost-effective, easy to operate, and effectively ruptures containers without exposing hazardous elements, improving handling and reducing the risk of component breakage.

Implementation Method 1

the guide member comprises a cam surface; and the first rupturing member comprises a cam follower surface, such that during relative movement of the first tube and the second tube from the first position to the second position along the first motion path, the cam follower surface of the first rupturing element engages with the cam surface of the guide member to guide the rupturing portion of the first rupturing member along the second motion path

AI summary

An aerosol-generating system is provided, including a first container including at least one aerosol-generating substrate; a rupturing system including a first tube and a second tube, the first and second tubes being arranged in operational engagement defining a volume, wherein the first and second tubes are movable relative to each other along a first motion path from a first position to a second position, such that the defined volume is larger in the first position than in the second position, wherein the first tube includes a first rupturing member disposed at least partially inside the first tube, such that in the first position, the first rupturing member is contained completely in the defined volume of the first and second tubes, and wherein in the second position, the first rupturing member at least partially protrudes from the defined volume to rupture the container including said substrate.
