Solution Overview

Problem

Existing aerosol provision systems face challenges in efficiently testing and confirming the post-sale activation (PSA) capability of aerosol provision devices, leading to increased costs and complexity with each new product release or feature addition.

Innovation Solution

A test fixture with processing circuitry is provided, capable of sending a transition signal to aerosol provision devices to transition between initial and transitioned states during functional tests. The transition signal has a message format with a data portion and a length indicator, allowing for efficient testing and adaptation to different device configurations.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a new signaling paradigm is implemented for each new product release or feature addition, then the aerosol provision device can support PSA functionality, but the test fixture must be redesigned for each product, increasing cost and complexity

Engineering Contradiction:

ImprovePSA functionalityVSAvoidtest fixture design

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The test fixture is designed with a universal signaling interface that can handle multiple signaling paradigms through software configuration rather than hardware redesign. The processing circuitry is configured to recognize and process different message formats and transition signals, allowing a single physical test fixture to test multiple device versions and configurations.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The signaling paradigm is implemented through configurable parameters in the processing circuitry rather than fixed hardware design. By changing software parameters and signal processing logic, the same test fixture can adapt to different messaging formats, transition types, and device configurations without physical redesign.

Inventive Principle:

Principle #35Parameter changes

2Reliability

If authentication methods require interaction with a host device, then age verification can be performed, but the testing process becomes more complex and time-consuming

Engineering Contradiction:

Improveage verificationVSAvoidauthentication process

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The test fixture performs preliminary authentication testing by simulating the host device interaction and pre-validating the signaling pathway during manufacturing testing. This preliminary action ensures that the authentication functionality is verified before the device reaches the customer, reducing the need for repeated authentication steps.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The test fixture acts as an intermediary that simulates the host device during testing, providing a controlled environment to validate authentication sequences. This intermediary role allows comprehensive testing of authentication logic without requiring actual host device interaction during the testing phase.

Inventive Principle:

Principle #24Intermediary (Mediator)

AI summary

A test fixture for testing aerosol provision devices includes a housing, a plurality of testing modules disposed at the housing where each of the testing modules includes a cavity configured to receive a portion of an aerosol provision device, and processing circuitry operably coupled to the testing modules. Each of the testing modules may be configured to interface with an assembly of a respective one of the aerosol provision devices to transition the assembly between an initial state and a transitioned state during a functional test controlled by the processing circuitry. The processing circuitry may be configured to conduct the functional test of at least two of the testing modules simultaneously.
