Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing aerosol-generating device extractors face reliability issues due to a stopper and indent engagement mechanism that deteriorates over time, leading to difficulties in attachment and detachment, affecting stability and usability.
Innovation Solution
An extractor with a resilient coupling element that moves independently of the body, allowing for repeated attachment and detachment without deformation, ensuring a longer lifespan and consistent aerosol delivery by isolating deformation to the coupling element.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a stopper and indent engagement mechanism is used to couple the extractor to the aerosol-generating device, then the extractor can be attached and detached, but the engagement mechanism deteriorates over time leading to unreliable coupling
Solution Approach 1:
The coupling system is divided into two independent parts: a resilient coupling element attached to the extractor body and a corresponding engagement feature on the aerosol-generating device. This segmentation allows the resilient element to absorb wear and deformation independently from the extractor body, maintaining reliable coupling over time while enabling repeated attachment and detachment operations.
2Ease of operation
If the extractor body undergoes repeated deformation during attachment and detachment, then the coupling mechanism can be engaged and disengaged, but the extractor body deteriorates and may break
Solution Approach 1:
The deformation function is extracted from the extractor body and assigned to a separate resilient coupling element. This resilient element is specifically designed to undergo elastic deformation during attachment and detachment, while the extractor body remains substantially rigid and free from repeated deformation, preventing deterioration and breakage.
Solution Approach 2:
The resilient coupling element is designed with localized elasticity at specific coupling points, allowing deformation to be concentrated in this small region. The rest of the extractor body maintains its structural integrity and rigidity, ensuring that repeated operations do not compromise the overall strength of the extractor.
3Ease of operation
If the extractor body is repeatedly deformed during use, then attachment and detachment are enabled, but aerosol delivery consistency deteriorates
Solution Approach 1:
The deformation function is extracted from the extractor body and assigned to a separate resilient coupling element. This resilient element is specifically designed to undergo elastic deformation during attachment and detachment, while the extractor body remains substantially rigid and free from repeated deformation, preventing deterioration and breakage.
