Innovation Solution

A container design for planar aerosol-generating articles featuring an outer housing with a hinged lid and specific internal arrangements that maximize accessible surface area and efficient packing, allowing for easy handling and storage without extensive modifications.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of substance

If cylindrical aerosol-generating articles are used, then they can be manufactured with uniform heating, but a significant portion of the substrate is insufficiently heated and wasted

Engineering Contradiction:
Improvesubstrate material wasteVSAvoidheating uniformity
Core Design Contradiction:
Loss of substanceVSManufacturing precision

Solution Approach 1:

The container divides the storage space into multiple compartments, with dividing walls creating separate sections for different groups of articles. This segmentation allows planar articles to be stored in an organized manner that maximizes heating efficiency while minimizing substrate waste.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The invention transitions from cylindrical to planar aerosol-generating articles, changing the geometric dimensionality. Planar articles with surface-area-to-volume ratios greater than 1.5:1 enable more uniform heating across the substrate surface, eliminating the heating inefficiencies inherent in cylindrical designs.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Adaptability or versatility

If cylindrical aerosol-generating articles are used, then they can be stored in containers, but the size and shape require extensive modifications to existing manufacturing apparatus

Engineering Contradiction:
Improvecompatibility with existing apparatusVSAvoidmanufacturing complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The container design with a hinged lid and standardized compartments can accommodate multiple types of planar aerosol-generating articles. The universal design allows the same container structure to store different article configurations without requiring specialized modifications, enhancing adaptability while maintaining simplicity.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Volume of stationary object

If planar aerosol-generating articles are packed tightly in a container, then space is efficiently used, but interstitial space that assists gripping is reduced

Engineering Contradiction:
Improvecontainer space utilizationVSAvoidgripping ease
Core Design Contradiction:
Volume of stationary objectVSEase of operation

Solution Approach 1:

The container is divided into multiple compartments using dividing walls, creating separate groups of articles. This segmentation organizes the tightly packed planar articles into accessible sections, allowing users to easily grip and remove articles from specific compartments while maintaining efficient space utilization throughout the container.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The hinged lid acts as an intermediary mechanism that provides leverage and mechanical advantage for removing articles. When the lid is opened, it creates an access point that facilitates gripping of the tightly packed planar articles, compensating for the reduced interstitial space.

Inventive Principle:
Principle #24Intermediary (Mediator)

4Ease of operation

If planar aerosol-generating articles are arranged with major faces accessible, then handling is easier, but manufacturing precision requirements increase

Engineering Contradiction:
Improvehandling easeVSAvoidarrangement precision
Core Design Contradiction:
Ease of operationVSManufacturing precision

Solution Approach 1:

The container compartments are designed with dividing walls that guide and organize planar articles into specific orientations. This segmentation automatically aligns articles with their major faces accessible during removal, achieving the desired handling ease without requiring high-precision manual arrangement during manufacturing.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The container structure itself performs the orientation function through its geometric design. The compartments and dividing walls are configured to naturally position articles with major faces accessible, eliminating the need for additional precision-oriented manufacturing steps while maintaining ease of handling.

Inventive Principle:
Principle #25Self-service

AI summary

There is provided a container (100) of planar aerosol-generating articles (10). The container (100) comprises: an outer housing having an internal volume; and a plurality of planar aerosol-generating articles (10) disposed within the outer housing. The outer housing comprises: a box portion (102) having an access opening and comprising a box portion front wall (106) and a box portion rear wall (108); and a lid portion (104). The lid portion (104) is connected to the box portion (102) by a hinge line extending along a top edge of the box portion (102), and the lid portion (104) being moveable about the hinge line between: closed position, in which the lid portion (104) covers the access opening; and an open position, in which one or more of the planar aerosol-generating articles (10) can be removed through the access opening. The plurality of planar aerosol-generating articles (10) are arranged within the outer housing such that a first planar major face (12) of each planar aerosol-generating article (10) faces towards the box portion front wall (106).
