Solution Overview

Problem

Existing smoking alternatives that heat aerosolisable materials lack efficient and user-friendly mechanisms for inserting and securing the material, leading to potential misuse or damage during handling.

Innovation Solution

A sliding door assembly with a mechanical latching arrangement, featuring a cam and follower mechanism, allows for secure and easy access to the aerosolisable material while preventing accidental opening or closing, using Polycarbonate/Acrylonitrile Butadiene Styrene (PC/ABS) materials for durability.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a cartridge-type consumable container is used, then portability and ease of use are improved, but the amount of liquid composition that can be stored is limited

Engineering Contradiction:
ImproveportabilityVSAvoidstorage capacity
Core Design Contradiction:
Ease of operationVSQuantity of substance

Solution Approach 1:

The system is divided into two separate parts: a portable cartridge-type consumable container (100) for easy handling and a separate storage container (200) for bulk storage. The consumable container can be detached and replaced, allowing users to carry only the small cartridge while the larger storage container remains stationary or is stored separately. This segmentation resolves the contradiction by enabling portability of the consumable unit while maintaining the option for large-scale storage elsewhere.

Inventive Principle:
Principle #1Segmentation

2Weight of moving object

If the container is made lightweight and small, then portability is improved, but the storage capacity is reduced

Engineering Contradiction:
Improvecontainer weightVSAvoidliquid composition volume
Core Design Contradiction:
Weight of moving objectVSQuantity of substance

Solution Approach 1:

The container system is segmented into a lightweight portable cartridge (100) containing the liquid composition and a separate storage container (200). The cartridge is designed to be small and light for portability, while the storage container can be larger and heavier since it doesn't need to be frequently carried. This allows the system to provide both lightweight portability and adequate storage capacity by distributing the weight and volume across separate components.

Inventive Principle:
Principle #1Segmentation

3Difficulty of detecting and measuring

If the container is made transparent, then visibility of remaining liquid is improved, but aesthetic appearance and protection from light-induced degradation are worsened

Engineering Contradiction:
Improveliquid level visibilityVSAvoidlight-induced degradation
Core Design Contradiction:
Difficulty of detecting and measuringVSObject-affected harmful factors

Solution Approach 1:

A window (131) is provided in the container wall as an intermediary structure that allows light to pass through for visibility of the liquid level and remaining composition, while the rest of the container can be made opaque or dark-colored to protect the liquid from light-induced degradation. The window acts as a selective opening that provides the necessary visual information without exposing the entire contents to harmful light exposure.

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

Provided is an assembly for use in an apparatus for heating aerosolisable material to volatalise at least one component of the aerosolisable material to generate an inhalable aerosol, the assembly having a structure delimiting an opening through which aerosolisable material can be removably inserted into the apparatus, a door coupled to the structure and movable between an open position where access to the opening is unrestricted, and a closed position where access to the opening is restricted, and a latching arrangement configured to hold the door in at least one of the open position and the closed position when the door is in the one of the open position and the closed position until an external force is applied, in use, to release the latching arrangement.
