Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If compressed air is used to blow off electrical components, then particles can be removed, but the cleaning performance is insufficient and particulate contaminants are not effectively removed
Solution Approach 1:
The patent applies dynamic vortex flow instead of static compressed air blowing. The cleaning medium is introduced tangentially to create rotating vortex flow that dynamically adapts to the component geometry, significantly improving particle removal efficiency while maintaining cleaning effectiveness for sensitive electrical components
Solution Approach 2:
The patent changes the flow parameters by introducing cleaning medium tangentially to generate vortex flow with specific rotational characteristics. This parameter change transforms the cleaning mechanism from simple pressure blowing to controlled vortex flow, achieving both high particle removal efficiency and effective cleaning of sensitive components
2Device complexity
If a cylindrical cleaning chamber is used, then the structure is simple, but the flow pattern does not create effective vortex flow for particle capture
Solution Approach 1:
The patent applies local quality by introducing the cleaning medium tangentially at specific locations on the cylindrical chamber wall rather than using uniform distribution. This localized tangential introduction creates effective vortex flow in critical areas, achieving reliable particle capture while maintaining the simplicity of the cylindrical chamber structure
Solution Approach 2:
The patent uses pneumatic principles by introducing cleaning medium through tangential nozzles to generate vortex flow. The pneumatic flow pattern creates rotational motion that enhances particle capture effectiveness within the simple cylindrical chamber, combining structural simplicity with effective cleaning action
