Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a plurality of elongate second strips comprising inductively heatable susceptor material are attached to an elongate carrier strip that is folded along one or more fold lines to form two or more elongate carrier regions, then uniform heating of the aerosol generating material is improved, but device complexity increases
Solution Approach 1:
The carrier strip is folded along one or more fold lines to form two or more elongate carrier regions, dividing the heating structure into multiple segments. Each carrier region can be independently positioned to contact and heat different portions of the aerosol generating material, ensuring uniform heating across the entire substrate while maintaining a manageable structural complexity through modular segmentation.
2Reliability
If elongate first strips comprising aerosol generating material and elongate second strips comprising inductively heatable susceptor material are arranged to form a rod-shaped aerosol generating article, then aerosol characteristics are optimized, but manufacturing difficulty increases
Solution Approach 1:
The elongate first strips comprising aerosol generating material and the elongate second strips comprising inductively heatable susceptor material are merged by attaching the second strips to the carrier strip, forming an integrated rod-shaped aerosol generating article. This combination ensures that the aerosol-generating components and heating components are pre-assembled in the correct configuration, optimizing aerosol characteristics while simplifying the manufacturing process through a single integrated structure that can be produced as one unit.

Function Achieved in This Case
This configuration ensures effective and uniform heating of the aerosol generating material, producing a consistent aerosol for inhalation, while allowing for easy and reliable mass production.
Implementation Method 1
an induction coil is provided in the device and an inductively heatable susceptor is provided to heat the aerosol generating substrate. Electrical energy is supplied to the induction coil when a user activates the device which in turn generates an alternating electromagnetic field. The susceptor couples with the electromagnetic field and generates heat
Implementation Method 2
heating the aerosol generating material, without burning the aerosol generating material, to volatise at least one component of the aerosol generating material and thereby generate a heated vapour which cools and condenses to form an aerosol
