Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If a paper filter is used in the filter section, then the structure is simple and manufacturing is easy, but the temperature of the aerosol cannot be effectively regulated
Solution Approach 1:
The filter section is segmented into multiple functional zones: a paper filter region for basic filtration, a hollow member region for thermal management, and a vent hole region for air intake control. This segmentation allows each zone to perform its specific function independently, achieving temperature regulation without overly complicating the overall structure.
Solution Approach 2:
The hollow member is disposed inside the paper filter, creating a nested structure where the hollow member is positioned within the filter section. This nesting allows the thermal management component to be integrated within the existing filter structure, adding temperature regulation functionality while minimizing increases in device complexity.
2Temperature
If air flow is increased through vent holes to cool the aerosol, then aerosol temperature is regulated, but the delivery efficiency of substances like nicotine or glycerol decreases
Solution Approach 1:
The vent holes are positioned at specific locations on the tip paper, and the hollow member is positioned at specific locations within the filter section. This local positioning ensures that air intake occurs at optimal points where it can cool the aerosol effectively while minimizing interference with the pathways that deliver substances to the user.
Solution Approach 2:
The hollow member acts as an intermediary structure that facilitates heat exchange between the aerosol and the surrounding air. It provides a controlled interface where cooling can occur through thermal conduction and convection, while the paper filter maintains the substance delivery pathway, thus mediating between temperature regulation and substance delivery requirements.
3Temperature
If the hollow member is made larger to improve cooling, then aerosol temperature regulation improves, but the space for substance delivery is reduced
Solution Approach 1:
The hollow member is designed with a size that provides sufficient cooling capability without occupying excessive space. The vent holes are sized and positioned to provide adequate air intake for temperature regulation while maintaining appropriate flow paths for substance delivery. This partial action approach ensures that cooling is effective but does not overly compromise the delivery function.
