Flavor Inhaler Airflow Layout for Easy Cleaning and Dropout Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing flavor inhalers face challenges in accommodating novel consumable materials and maintaining air flow paths suitable for these configurations, with issues in cleaning and preventing consumable material dropouts.
Innovation Solution
A flavor inhaler design featuring a cover portion that opens/closes along a longitudinal direction, with a first opening allowing external air inflow, and a recessed air communication path that prevents finger obstruction and condensation, while enabling easy maintenance and temperature control of the air flow.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a novel consumable material configuration is introduced, then the flavor inhaler can accommodate new material formats, but the cover portion and air flow path need to be rearranged to suit the new configuration
Solution Approach 1:
The cover portion is designed to perform multiple functions: it serves as both a closure for the accommodating portion and as a structural element that defines the air flow path. By making the cover portion multi-functional, the design can accommodate novel consumable material configurations without requiring separate redesign of the cover and air flow path, thus resolving the contradiction between adaptability and device complexity
2Ease of repair
If the cover portion is designed to open/close along the longitudinal direction, then easy maintenance is enabled, but the air flow path arrangement becomes more complex
Solution Approach 1:
The accommodating portion is segmented into a cover portion and a body portion, with the cover portion capable of opening and closing along the longitudinal direction. This segmentation allows easy access to the interior of the accommodating portion for maintenance purposes. The air flow path is arranged to pass through the consumable material from the proximal end to the distal end, which can be cleaned by inserting a straight cotton swab or brush through the open cover portion
3Ease of operation
If the first opening portion is provided facing the cover portion, then external air can flow in easily, but the opening may be obstructed by user's finger
Solution Approach 1:
The first opening portion is provided on the rear face of the accommodating portion, which is a different spatial dimension relative to the user's hand grip. This dimensional arrangement allows external air to flow in easily while preventing finger obstruction, as the opening is positioned in a location that is not easily accessible to the user's fingers during normal operation
4Object-affected harmful factors
If the opening portion is positioned close to the distal end, then condensation can be prevented, but the air flow path becomes more complex
Solution Approach 1:
The air flow path is configured to pass through the consumable material from the proximal end to the distal end, with the first opening portion positioned on the rear face near the distal end. This preliminary arrangement of the air flow path ensures that external air enters close to the distal end, which prevents condensation from forming in the air flow path before reaching the user's mouth
