Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a single airflow pathway is used in conventional electrically heated smoking systems, then the device structure is simple, but the aromatic notes and flavoring aspects are insufficient compared to conventional cigarettes and cigars
Solution Approach 1:
The airflow pathway is segmented into two separate channels: a first airflow pathway that delivers aerosol to the user's mouth, and a second airflow pathway that delivers aroma to the user's nose. This segmentation allows independent optimization of flavor delivery (through the aerosol pathway) and aromatic notes (through the aroma pathway), resolving the contradiction between structural simplicity and sensory quality.
Solution Approach 2:
The invention adds a new dimension to the airflow system by introducing a radial airflow component through openings in the air chamber wall, in addition to the axial airflow through the aerosol generating article. This dimensional addition enables simultaneous delivery of aerosol and aroma through different spatial pathways, improving both aromatic notes and flavoring aspects without significantly complicating the overall device structure.
2Device complexity
If aerosol is delivered only to the user's mouth, then the device structure is simple, but the user experience lacks the aromatic notes provided by conventional smoking articles
Solution Approach 1:
The user experience is segmented into two sensory channels: oral delivery of aerosol for flavor and nasal delivery of aroma for aromatic notes. This segmentation mirrors the natural way humans experience flavor and smell, significantly improving user experience quality. The device complexity increase is minimal, involving only additional openings in the air chamber and corresponding airflow pathways.
Solution Approach 2:
The air chamber serves as an intermediary structure that facilitates the separation and directional delivery of aerosol and aroma. By incorporating openings in its wall, the air chamber mediates between the heating element and the user's sensory organs, enabling simultaneous oral and nasal delivery without requiring complex additional components.
3Manufacturing precision
If a flavor generating article is added to provide aromatic notes, then the aromatic notes improve, but the device complexity increases
Solution Approach 1:
The flavor generating article is merged with the existing air chamber structure, utilizing the air chamber as both a holding structure and an airflow distribution component. The openings required for aroma delivery are integrated into the air chamber wall, combining multiple functions (aerosol generation, aroma generation, and directional delivery) into a single integrated module, thereby minimizing the increase in device complexity.
Solution Approach 2:
The air chamber is designed with multi-functionality: it holds the flavor generating article, generates aerosol when heated, distributes aroma through its wall openings, and directs both aerosol and aroma to appropriate delivery pathways. This universal design reduces the need for separate dedicated components for each function, limiting the increase in device complexity while achieving improved aromatic notes.
