Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If electrically-generated heat is used to vaporize tobacco or aerosol forming materials, then the sensations of smoking can be provided without combustion, but inconsistent performance characteristics occur including inconsistent release of flavors and inadequate loading of aerosol forming materials
Solution Approach 1:
The patent applies parameter changes by optimizing the physical and chemical properties of the aerosol-forming material composition, including specific ratios of tobacco material (10-45% by weight), non-tobacco botanical materials, binders (0.5-1.5% by weight), water content, and aerosol-forming components. These parameter adjustments ensure consistent vaporization performance and flavor release without combustion, resolving the reliability issue while maintaining the harm reduction benefit.
Solution Approach 2:
The invention uses composite materials by creating a multi-component aerosol-forming material that combines tobacco material, non-tobacco botanical materials, binders, water, and aerosol-forming components into a beaded substrate. This composite structure ensures consistent heating and vaporization characteristics, improving performance reliability while avoiding incomplete combustion and pyrolysis products.
2Object-affected harmful factors
If electrical energy is used to heat tobacco and aerosol generating substrate materials, then combustion can be avoided, but poor sensory characteristics result
Solution Approach 1:
The patent improves sensory characteristics by optimizing parameters including the composition of aerosol-forming materials, water content, binder types and concentrations, and the physical form of the substrate (beaded structure). These parameter changes enable consistent flavor release and pleasant sensory experience while maintaining the combustion-free heating approach.
Solution Approach 2:
The invention applies local quality by ensuring uniform distribution of aerosol-forming materials throughout the beaded substrate structure, with consistent loading of tobacco and non-tobacco botanical materials. This uniform local composition throughout the substrate ensures consistent sensory characteristics and flavor release during vaporization.
3Quantity of substance
If aerosol forming materials are loaded on substrates, then inhalable substance can be provided, but inadequate loading occurs leading to poor performance
Solution Approach 1:
The patent addresses loading consistency by specifying precise parameter ranges for aerosol-forming material composition, including tobacco material (10-45% by weight), non-tobacco botanical materials, binders (0.5-1.5% by weight), and water content. These controlled parameters ensure adequate and consistent loading of inhalable materials on the substrate beads during manufacturing.
Solution Approach 2:
The invention achieves homogeneity by ensuring uniform mixing and distribution of all components (tobacco material, non-tobacco botanical materials, binders, water, and aerosol-forming components) throughout the beaded substrate. This homogeneous composition ensures consistent loading of aerosol-forming materials, improving manufacturing precision and performance reliability.
