Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If filtration elements are added to the nozzle guide, then particle removal effectiveness is improved, but device complexity increases
Solution Approach 1:
The filtration membranes are integrated directly into the lateral openings of the nozzle guide body, merging the filtration function with the existing structural component. This eliminates the need for separate filtration assemblies while achieving effective particle removal from medical gases and vacuum streams.
Solution Approach 2:
Filtration membranes with controlled porosity are installed in the lateral openings of the nozzle guide. These porous materials allow gas and vacuum to pass through while blocking particles ranging from dust and debris to bacteria, effectively addressing contamination without adding complex mechanical filtration systems.
2Ease of repair
If the nozzle guide is designed for easy maintenance and replacement, then ease of repair is improved, but manufacturing precision requirements increase
Solution Approach 1:
The nozzle guide is divided into separable components including the main body with lateral openings and removable filtration membranes. This segmentation allows individual components to be replaced independently during maintenance without requiring complete disassembly of the entire assembly, facilitating easy repair while using standard manufacturing tolerances.
Solution Approach 2:
The filtration membranes are designed as extractable elements that can be removed from the lateral openings of the nozzle guide. This extraction capability enables maintenance personnel to access and replace filtration elements without specialized tools or complex procedures, improving ease of repair while maintaining acceptable manufacturing precision through simple insertion and retention features.
