Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a separate heating device is used to generate aerosol, then aerosol generation function is achieved, but device structure becomes complex and manufacturing cost increases
Solution Approach 1:
The heating function is merged with the aerosol generating material itself. The vaporizing agent is incorporated into the composition along with tobacco material, eliminating the need for a separate heating device. When exposed to air, the vaporizing agent generates heat that directly heats the tobacco material to produce aerosol, combining the heating function and aerosol generation function into a single integrated system.
Solution Approach 2:
The composition is designed to be self-heating through the vaporizing agent that generates oxidizing heat when exposed to air. The system serves itself by using the chemical reaction of the vaporizing agent with oxygen to produce the necessary heat for aerosol generation, without requiring external power sources or separate heating devices.
2Device complexity
If conventional heating device with electric wiring and battery is used, then aerosol can be generated, but structural complexity and manufacturing cost increase
Solution Approach 1:
The electric wiring and battery components are extracted and removed from the system. Instead of using conventional electrical heating components, the invention uses a chemical-based heating mechanism where the vaporizing agent in the composition generates heat through oxidation when exposed to air, eliminating the need for complex electrical systems.
Solution Approach 2:
The mechanical/electrical heating system is replaced with a chemical system. The vaporizing agent undergoes oxidation reaction to generate heat, substituting the electrical heating mechanism with a chemical reaction-based heating mechanism that is simpler and less costly to manufacture.
3Reliability
If separate heating device and power supply are used, then reliable aerosol generation is achieved, but device complexity increases
Solution Approach 1:
The composition serves multiple functions simultaneously: it contains the tobacco material for aerosol generation, the vaporizing agent for heat generation, and the binding agent for structural integrity. This multi-functional design ensures reliable aerosol generation while maintaining simple structure without requiring separate heating devices or power supplies.
