Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing electronic aerosol provision systems, such as e-cigarettes, face challenges in secure attachment and exposed profile design, which can lead to usability and protection issues.

Innovation Solution

A device with a housing comprising a chassis section and a hatch section that is moveable between two positions, allowing the aerosol forming component to be enclosed within the device, reducing the overall profile and enhancing protection, while maintaining accessibility for aerosol generation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the aerosol provision component is made separable from the device section, then re-usability of the device section is improved, but the overall device complexity increases

Engineering Contradiction:

Improvere-usabilityVSAvoiddevice complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The device is divided into separable components: a reusable device section containing the power source and electronics, and a disposable aerosol provision component containing the heating element and source material. This segmentation allows the device section to be reused while the aerosol provision component is replaced, resolving the contradiction between re-usability and complexity by making the separable interface a standard feature.

Inventive Principle:

Principle #1Segmentation

2Shape

If the aerosol provision component extends from the device section in a longitudinal format, then conventional appearance is improved, but the profile exposure increases

Engineering Contradiction:

Improveconventional appearanceVSAvoidprofile exposure

Core Design Contradiction:

ShapeVSObject-affected harmful factors

Solution Approach 1:

The aerosol provision component is designed to nest within or attach compactly to the device section, rather than extending far outward. This reduces the overall profile exposure and protection issues while maintaining a conventional longitudinal appearance when assembled, resolving the contradiction between shape and harmful exposure.

Inventive Principle:

Principle #7Nested doll (Nesting)

3Reliability

If screw-threads or bayonet-fittings are used for attachment, then secure connection is improved, but the manufacturing complexity increases

Engineering Contradiction:

Improvesecure attachmentVSAvoidmanufacturing complexity

Core Design Contradiction:

ReliabilityVSEase of manufacture

Solution Approach 1:

The aerosol provision component is designed as a disposable unit that is replaced rather than refilled or repaired. This allows the use of simple, cost-effective attachment mechanisms that provide sufficient secure connection for the component's intended lifespan, resolving the contradiction between reliable attachment and manufacturing simplicity by accepting the component as temporary.

Inventive Principle:

Principle #27Cheap short-living objects (Disposable)
