Solution Overview

Problem

Existing smoking alternatives, such as heat-not-burn products, lack a secure and user-friendly mechanism for accessing and replacing the power source, which can lead to accidental disconnection and potential damage.

Innovation Solution

An aerosol provision device with a locking mechanism controlled by a multi-step user interface, requiring specific movements to unlock and access the power source, ensuring secure and intentional operation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a simple cover is used to close the power source receiving portion, then the device structure is simple and easy to manufacture, but the power source can be accidentally disconnected or damaged

Engineering Contradiction:
Improvepower source connection securityVSAvoidlocking mechanism complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The locking mechanism is engaged automatically when the cover is closed, preventing accidental disconnection before use. The control member is positioned to require intentional activation, ensuring the power source is securely locked in place before the device is operated.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The control member acts as an intermediary between the user and the locking mechanism. It translates user input (pressing or rotating) into the engagement or disengagement of the locking mechanism, providing a controlled interface that prevents accidental activation while enabling intentional access.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If a secure locking mechanism is implemented, then accidental disconnection is prevented, but the ease of operation for accessing the power source is reduced

Engineering Contradiction:
Improvepower source connection securityVSAvoidpower source access convenience
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The locking mechanism is designed to engage automatically when the cover is closed, eliminating the need for separate locking actions. The control member integrates both locking and unlocking functions, allowing the user to maintain security while easily accessing the power source when needed.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The locking mechanism uses electromagnetic actuation instead of purely mechanical systems. The motor or linear actuator provides controlled engagement and disengagement, reducing the physical effort required by the user while maintaining secure locking during operation.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

3Reliability

If the control member requires multiple movements to release the locking mechanism, then accidental release is prevented, but the number of operational steps increases

Engineering Contradiction:
Improvelocking mechanism reliabilityVSAvoidtime to access power source
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The control member can be activated through different dynamic inputs (pressing or rotating), allowing flexible user interaction. The system adapts to the user's action type, providing a responsive interface that maintains security while enabling quick access when intentionally triggered.

Inventive Principle:
Principle #15Dynamics

AI summary

An aerosol provision device for use with an aerosol generating material comprises a power source receiving portion and a removeable power source arranged within the power source receiving portion for supplying power for consumption by a component of the device. The aerosol provision device also comprises a cover arranged such that when in a closed position the cover closes an opening to the power source receiving portion, along with a locking mechanism arranged to hold the cover in the closed position. The device further comprises a user interface comprising a control member configured to control electrical operation of the device and is arranged to release the locking mechanism so as to allow the cover to move out of the closed position.
