Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If multiple ionizers are distributed throughout the system, then the ionization coverage is improved, but the homogeneity of ion density across the airflow deteriorates
Solution Approach 1:
An intermediate stage is introduced between the ionization stage and collector stage, comprising multiple attractor elements arranged in a matrix. These attractor elements act as intermediaries that capture and redistribute ions, creating a more uniform ion density field across the airflow before particles enter the collector stage.
Solution Approach 2:
The ionization and attraction process is segmented into distinct stages: an ionization stage with ionizers, an intermediate stage with multiple attractor elements arranged in rows and columns, and a collector stage. This segmentation allows each stage to perform its function optimally and contributes to overall ion distribution homogeneity.
2Productivity
If ionizers are placed close together, then the ionization efficiency is improved, but the structural complexity of the device increases
Solution Approach 1:
The attractor elements serve multiple functions: they attract ions toward the collector stage, distribute ions uniformly across the airflow, and structurally organize the ionization process. This multi-functionality reduces the need for additional components and simplifies the overall device structure despite the multiple stages involved.
3Manufacturing precision
If an intermediate stage with attractor elements is added, then the homogeneity of ion distribution is improved, but the device complexity increases
Solution Approach 1:
Different regions of the device are assigned different functions: ionizers in the ionization stage generate ions, attractor elements in the intermediate stage distribute ions locally across the airflow, and collectors in the final stage capture particles. This local specialization allows each component to be simple in design while the system as a whole achieves high ion distribution homogeneity.
