Engineering Contradictions & Design Principles

VSEngineering 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

Engineering Contradiction:
Improveion densityVSAvoidhomogeneity of ion distribution
Core Design Contradiction:
Quantity of substanceVSManufacturing precision

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.

Inventive Principle:
Principle #24Intermediary (Mediator)

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.

Inventive Principle:
Principle #1Segmentation

2Productivity

If ionizers are placed close together, then the ionization efficiency is improved, but the structural complexity of the device increases

Engineering Contradiction:
Improveionization efficiencyVSAvoidstructural complexity
Core Design Contradiction:
ProductivityVSDevice complexity

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.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Manufacturing precision

If an intermediate stage with attractor elements is added, then the homogeneity of ion distribution is improved, but the device complexity increases

Engineering Contradiction:
Improvehomogeneity of ion distributionVSAvoiddevice complexity
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

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.

Inventive Principle:
Principle #3Local quality
