Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If aerosol generating material is applied to the support surface without surface modification, then the manufacturing process is simpler, but the application precision and material adhesion are insufficient
Solution Approach 1:
The support surface is pre-modified with a hydrophobic coating before applying the aerosol generating material. This preliminary action creates distinct modification areas that control where the material will adhere, ensuring precise application without requiring complex real-time control mechanisms during the application process itself.
Solution Approach 2:
The support surface is created with non-uniform properties through selective hydrophobic modification of specific areas. This local quality differentiation allows the material to be applied precisely to designated regions while maintaining manufacturing simplicity, as the precision is built into the surface structure rather than the application mechanism.
2Manufacturing precision
If the support surface is modified to improve material application control, then the manufacturing precision is improved, but the manufacturing time increases
Solution Approach 1:
The hydrophobic modification of the support surface is performed as a preliminary step before material application. This allows the modification to be optimized independently and potentially performed in batch processes, reducing the time impact on the overall manufacturing cycle when material application is the critical path.
Solution Approach 2:
The manufacturing process is segmented into distinct stages: surface modification, material application, and setting. This segmentation allows each stage to be optimized independently, and the surface modification can be performed once for multiple material applications, amortizing the time cost across multiple production cycles.
3Productivity
If aerosol generating material is applied to large areas of the support, then the productivity is improved, but the control over material setting and uniformity becomes difficult
Solution Approach 1:
The support surface is divided into multiple modification areas with controlled hydrophobic properties. This allows large-area production while maintaining precise control over material distribution and setting in each local region, as the hydrophobic boundaries prevent material migration between zones.
Solution Approach 2:
The large support surface is segmented into multiple discrete modification areas where material is applied separately. This segmentation enables parallel processing of multiple zones, maintaining productivity while ensuring each zone achieves proper material setting control through its defined boundaries.
4Reliability
If the aerosol generating material is applied without hydrophobic modification areas, then the manufacturing process is simpler, but the material adhesion and film stability are reduced
Solution Approach 1:
The support surface incorporates localized hydrophobic modification areas that provide enhanced adhesion and stability for the aerosol generating material. These localized modifications create distinct zones where material adheres more reliably, forming stable films without requiring complex overall surface treatment or additional stabilization mechanisms.
