Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a cone-shaped leaking hole with decreasing diameter is used to balance air pressure, then the pressure balancing function is achieved, but the processing steps become complicated and manufacturing efficiency decreases
Solution Approach 1:
The leaking hole is divided into multiple segments (first leaking hole, second leaking hole, third leaking hole) with different diameters, replacing the complex cone-shaped single hole. This segmentation simplifies the processing steps while maintaining the pressure balancing function, as each circular hole can be easily manufactured independently.
Solution Approach 2:
The invention changes the geometric parameters of the leaking hole from a continuous cone shape to discrete circular holes with specific diameters (first, second, and third leaking holes having different diameters). This parameter discretization simplifies manufacturing while achieving the same pressure balancing effect.
2Reliability
If a cone-shaped leaking hole is used to prevent shielding failure, then the leaking structure reliability is improved, but the device complexity increases
Solution Approach 1:
The single cone-shaped hole is segmented into multiple circular holes (first, second, third leaking holes) distributed across different locations. This segmentation reduces structural complexity while maintaining reliability through distributed pressure balancing capability.
Solution Approach 2:
Instead of using a single complex cone-shaped hole, the invention inverts the approach by using multiple simple circular holes. This inversion simplifies the structure while achieving the same or better functional performance.
3Reliability
If multiple leaking holes with different diameters are used, then the pressure balancing and dust-proof performance are improved, but the manufacturing precision requirements increase
Solution Approach 1:
The leaking structure is segmented into multiple holes with different diameters, where each hole can be manufactured with standard precision. The segmentation allows for easier quality control compared to a single complex cone-shaped hole requiring high precision throughout.
Solution Approach 2:
The invention changes from a continuous parameter (cone angle and diameter variation) to discrete parameters (specific diameters of first, second, and third holes). This discretization relaxes manufacturing precision requirements while maintaining functional performance.
