Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If electrical heating is used to vaporize tobacco or botanical materials, then combustion products are reduced, but flavor release consistency and aerosol formation quality deteriorate
Solution Approach 1:
The patent applies parameter changes by precisely controlling heating temperature and duration to achieve vaporization without combustion. The substrate is heated to a controlled temperature range that releases flavors and forms aerosol while avoiding the harmful effects of combustion, thus resolving the contradiction between reducing harmful factors and maintaining reliable flavor release.
Solution Approach 2:
The patent uses composite materials by combining tobacco or botanical materials with specific binders and aerosol-forming components in a beaded substrate. This composite structure ensures consistent flavor release and proper aerosol formation while maintaining the benefit of reduced combustion products through controlled electrical heating.
2Object-affected harmful factors
If electrical heating is used to vaporize materials, then combustion is reduced, but aerosol formation quality deteriorates
Solution Approach 1:
The patent controls heating parameters (temperature, time, power) to optimize aerosol formation while avoiding combustion. By adjusting these parameters, the system achieves high-quality aerosol generation from the beaded substrate without the harmful effects of combustion.
Solution Approach 2:
The beaded substrate contains porous structures that facilitate uniform heating and consistent aerosol release. The porous material allows electrical heating to efficiently vaporize the aerosol-forming components while maintaining controlled combustion-free operation, thus improving aerosol formation quality without combustion.
3Device complexity
If simple heating methods are used, then device complexity is reduced, but sensory characteristics deteriorate
Solution Approach 1:
The patent employs composite beaded substrates containing tobacco or botanical materials, binders, and aerosol-forming components. This composite structure delivers superior sensory characteristics including flavor consistency and aerosol quality while maintaining relatively simple device architecture with controlled electrical heating.
