Aerosol provision systems face issues with article reliability and predictability due to continuous use leading to degradation and potential failure, as refilling with aerosol-generating material can cause degradation of internal components.

Innovation Solution

A refilling device with a motor-driven interface system that transfers aerosol-generating material from a reservoir to an article, using a nozzle block and plunger mechanism to facilitate efficient and controlled refilling.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If the article is continuously used to extend its service life, then the productivity is improved, but the reliability deteriorates due to component degradation

Engineering Contradiction:
Improveservice lifeVSAvoidcomponent reliability
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The system is divided into two main segments: a reusable aerosol provision device and a replaceable article. The article can be separated from the device and refilled independently, allowing the consumable material to be replenished without replacing the entire assembly. This segmentation enables continuous use of the same article with refilling, extending service life while maintaining reliability through controlled refilling processes.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

A refilling device acts as an intermediary system between the reservoir of aerosol-generating material and the article. The refilling device includes a motor-driven interface that precisely controls the transfer of material from the reservoir to the article, preventing overfilling and ensuring accurate refilling. This intermediary mechanism protects the article from degradation caused by improper refilling while enabling extended service life.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Device complexity

If manual refilling is used, then the device complexity is reduced, but the manufacturing precision and control of refilling process deteriorates

Engineering Contradiction:
Improverefilling mechanism complexityVSAvoidrefilling control precision
Core Design Contradiction:
Device complexityVSManufacturing precision

Solution Approach 1:

The refilling device is designed to automatically perform the refilling operation without requiring manual intervention during the actual transfer process. The motor-driven interface autonomously positions the article interface relative to the reservoir interface and controls the material transfer, providing precise refilling control while maintaining relatively simple overall device architecture.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The refilling process replaces manual mechanical operations with an automated motor-driven interface system. The motor precisely controls the movement of the article interface and the timing of material transfer from the reservoir, achieving high manufacturing precision and controlled refilling without complex mechanical linkages or multiple moving parts.

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

3Productivity

If the article is refilled multiple times, then the productivity is improved, but the reliability deteriorates due to repeated use

Engineering Contradiction:
Improvenumber of usesVSAvoidarticle reliability
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The refilling device incorporates detection mechanisms that monitor the refilling process and provide feedback to the control system. The system detects when the article interface engages with the reservoir interface, when material transfer is complete, and can identify potential issues such as leaks or improper positioning. This feedback enables controlled multiple refilling operations while maintaining reliability by preventing conditions that would cause degradation.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The refilling device is designed with protective features that prevent damage to the article during refilling operations. The motor-driven interface system carefully controls the positioning and engagement of components, and the detection mechanisms can identify potential problems before they cause reliability issues. This beforehand cushioning allows multiple refilling cycles without compromising the article's reliability.

Inventive Principle:
Principle #11Beforehand cushioning (Prior cushioning)
