Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing aerosol delivery devices for tobacco or tobacco-derived materials suffer from inconsistent performance characteristics, failing to replicate the sensations of traditional smoking without significant combustion or pyrolysis products.
Innovation Solution
The aerosol delivery device incorporates a segmented electrical heating assembly with independent heating members that heat segments of the aerosol source member, allowing for precise control of heat distribution and inhalable substance generation, using a combination of a moveable and stationary jaw with heating pins or elements to create a closed circuit for efficient heating.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a single heating element is used, then the device structure is simple, but the heating distribution is inconsistent leading to poor performance reliability
Solution Approach 1:
The heating assembly is divided into multiple independent heating members (first heating member and second heating member) that can be independently controlled. Each heating member has its own control circuit, allowing separate temperature and power regulation to achieve consistent heating distribution across different zones of the aerosol source member.
Solution Approach 2:
Different heating members are assigned to heat different segments of the aerosol source member (first segment and second segment). This allows localized temperature control where each heating member optimizes heating for its specific zone, improving overall heating consistency and performance reliability.
2Reliability
If electrical heating is used to avoid combustion, then harmful combustion products are reduced, but heating control precision is insufficient leading to inconsistent vaporization
Solution Approach 1:
The device incorporates temperature sensors that continuously monitor the temperature of each heating member and aerosol source member segment. The control circuits receive feedback from these sensors and automatically adjust power delivery to maintain optimal temperatures, ensuring consistent vaporization without combustion while improving heating control precision.
Solution Approach 2:
The system dynamically adjusts electrical parameters (voltage, current, power) to each heating member based on real-time temperature measurements and operational conditions. This precise parameter control enables consistent heating that avoids combustion thresholds while maintaining reliable vaporization performance.
