Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of substance
If conventional heating mechanisms are used in aerosol provision devices, then aerosol generation is achieved, but frequent replacement of aerosol-generating materials is required and material waste increases
Solution Approach 1:
The patent enables recovery and reuse of aerosol-generating materials by implementing a heating system that can be detached and reused with different material articles. The flexible coil configuration on the removable support allows the heating mechanism to be separated from the consumable material, enabling users to replace only the material article while retaining the expensive heating component, thus reducing material waste and cost.
2Adaptability or versatility
If resistive heating systems are used to create aerosol, then heating function is achieved, but the system lacks flexibility and efficiency in material utilization
Solution Approach 1:
The patent divides the aerosol provision device into separate functional modules: a reusable heating assembly with flexible coil configuration on a removable support, and a detachable material article. This segmentation allows the heating system to be manufactured separately and paired with different material types, enhancing versatility without requiring complex integration of heating and material components into a single unit.
Solution Approach 2:
The flexible coil configuration on the removable support provides dynamic adaptability, allowing the heating system to accommodate different material articles and be repositioned or reconfigured as needed. The flexible support enables the coil to conform to different geometries and maintain electrical connection while allowing mechanical movement and detachment, providing both flexibility and ease of manufacture.
3Power
If a flexible coil configuration with multiple parallel conductive tracks is implemented, then heating efficiency is improved, but device complexity increases
Solution Approach 1:
The patent merges multiple parallel conductive tracks onto a single flexible support structure, combining their heating functions into one integrated component. This merging approach increases heating power by providing multiple current paths simultaneously while avoiding the complexity of assembling separate coil components, as all tracks are formed together on the flexible support in a single manufacturing process.
