Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Aerosol-generating devices face issues with waste accumulation and residue deposition, leading to device impairment and compromised user experience due to the non-reusable nature of aerosol-forming articles, which results in frequent device cleaning challenges and environmental waste.
Innovation Solution
A reusable aerosol-generating article with a pivotable housing and compartment design allows for easy access and cleaning, incorporating a heating element and air-flow path, enabling multiple uses and reducing waste by separating aerosol-forming substrate replacement from device maintenance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If aerosol-forming articles are made disposable and discarded after use, then ease of operation is improved, but loss of substance increases due to large amount of waste
Solution Approach 1:
The aerosol-forming article is divided into two segments: a reusable housing and a disposable aerosol-forming substrate. The housing contains the compartment, filter, and mouthpiece, while the substrate is replaced after use. This segmentation allows the non-consumable parts to be reused, reducing waste while maintaining ease of operation.
Solution Approach 2:
The invention applies discarding and recovering by discarding only the consumed aerosol-forming substrate while recovering and reusing the housing, filter, and mouthpiece. This selective discarding reduces the overall waste generated compared to complete disposal of the entire article.
2Ease of operation
If aerosol-forming articles are discarded after use, then ease of operation is improved, but object-generated harmful factors increase due to residue deposition in device cavity
Solution Approach 1:
The aerosol-forming substrate is extracted as a separate replaceable component from the housing. This extraction allows the substrate to be removed and discarded after use, preventing residue from being deposited in the device cavity, while the housing remains clean and reusable.
Solution Approach 2:
By segmenting the article into housing and substrate, the invention isolates the residue-generating component (substrate) from the device cavity. When the substrate is replaced, residue is contained within the disposable portion and discarded with it, preventing contamination of the reusable housing and device cavity.
3Ease of repair
If the housing is made cleanable and accessible, then ease of repair is improved, but device complexity increases due to pivotable parts and compartment design
Solution Approach 1:
The housing incorporates pivotable parts that allow dynamic opening and closing access to the compartment. This dynamic design enables easy cleaning and substrate replacement while maintaining a compact closed structure, balancing cleanability with acceptable complexity.
