Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If sheets of material are crimped and gathered to form a body with controlled permeability and density, then aerosol modification performance is improved, but manufacturing complexity increases
Solution Approach 1:
The sheets are pre-crimped with a specific pattern (ridges and grooves with controlled spacing and depth) before being gathered into the final body structure. This preliminary structuring ensures consistent permeability and density characteristics are achieved during the gathering process, improving aerosol modification performance while maintaining manufacturing feasibility through standardized pre-processing steps.
Solution Approach 2:
The invention controls specific parameters of the crimp pattern (ridge spacing greater than 0.3 mm, ridge depth between 0.1-0.8 mm) and the gathering process to achieve targeted bulk density ranges (0.05-0.5 gms/cm³) and permeability characteristics. By optimizing these parameters, the system achieves reliable aerosol modification performance without requiring excessively complex manufacturing processes.
2Productivity
If aerosol modifying additives are applied to sheets as liquid with specific viscosity, then aerosol delivery efficiency is improved, but process control difficulty increases
Solution Approach 1:
The invention specifies applying aerosol modifying additives as liquids with controlled viscosity ranges (5-100 centipoise at 25°C). This parameter control ensures optimal delivery efficiency by balancing additive distribution uniformity with application feasibility. The viscosity specification provides clear process control criteria, reducing measurement and control difficulties while maintaining high aerosol delivery efficiency.
3Reliability
If sheets with large total width are used to ensure consistent performance, then aerosol modification consistency is improved, but material usage increases
Solution Approach 1:
The invention uses multiple sheets (typically 3-7 sheets per component) with controlled individual widths that are gathered together to form the final body. This segmentation approach ensures consistent performance across the component by distributing the functional requirements across multiple standardized sheets, while allowing optimization of total material usage through controlled sheet dimensions and efficient gathering configurations.
