Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If a heater element is used to heat the substrate, then aerosol generation is achieved, but energy efficiency is poor and temperature distribution is non-uniform
Solution Approach 1:
The patent replaces the conventional heater element (thermal conduction method) with an airflow-based heating system. Air is circulated through the consumable unit, utilizing convective heat transfer instead of direct contact with a heating element. This substitution improves energy efficiency and achieves more uniform temperature distribution throughout the aerosol-forming substance.
Solution Approach 2:
The invention employs an airflow system where air is pumped through the consumable unit to achieve heating and aerosol generation. The pneumatic flow of air serves dual purposes: as the heating medium and as the carrier for aerosol formation, eliminating the need for separate heating elements and improving overall energy efficiency.
2Productivity
If airflow passes through the consumable unit, then aerosol generation is achieved, but control over aerosol production is insufficient
Solution Approach 1:
The system incorporates controllable airflow parameters including variable flow rate, direction, and duration. The pump can be dynamically adjusted to deliver precise amounts of air through the consumable unit, enabling controlled aerosol generation. This dynamic control allows users to regulate aerosol production levels and consistency according to desired output.
Solution Approach 2:
The system includes sensors and control mechanisms that monitor airflow characteristics and aerosol generation in real-time. This feedback enables automatic adjustment of airflow parameters to maintain consistent aerosol production, improving both productivity and ease of operation through closed-loop control.
