Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If current connectors are used for fluid transfer, then the connection can be established quickly, but the seal reliability is insufficient and leakage may occur
Solution Approach 1:
The connector is divided into multiple functional segments: a separate wiper seal component for cleaning the mating surface, an O-ring seal for the primary sealing function, and a housing structure that positions both seals. This segmentation allows each seal to perform its specific function optimally, improving overall seal reliability while keeping the assembly process manageable.
Solution Approach 2:
The wiper seal performs a preliminary cleaning action on the mating surface of the port fitting before the O-ring seal makes contact. This preliminary wiping action removes contaminants that could compromise the seal, ensuring the O-ring seals against a clean surface and thereby improving seal reliability without requiring a complex multi-component sealing system.
2Adaptability or versatility
If a simple connector design is used, then the device complexity is low, but the connector cannot provide a tight seal across different fluid types and environments
Solution Approach 1:
The connector design incorporates universal sealing principles with the wiper seal and O-ring combination that can effectively seal against various fluid types (coolants, oils, vapors) and environmental conditions. The housing structure and seal arrangement provide a universal solution that adapts to different port fitting configurations while maintaining consistent sealing performance across diverse applications.
3Reliability
If the connector uses basic sealing components, then the manufacturing cost is low, but the connector fails to prevent leakage under pressure and varying conditions
Solution Approach 1:
The wiper seal acts as an intermediary element between the external environment and the O-ring seal. It prepares the mating surface by removing contaminants, thereby enabling the O-ring to perform its sealing function effectively. This intermediary action ensures leak-proof performance under pressure and varying conditions while using standard, easily manufactured seal components.
