Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If traditional coupling devices are used for media-conducting lines, then connection strength is achieved, but assembly complexity and cost increase
Solution Approach 1:
The coupling device is divided into distinct functional segments: an outer coupling section, an inner coupling section, and a locking element with locking arc sections. This segmentation allows each component to be manufactured independently and assembled through simple insertion, reducing overall assembly complexity while maintaining connection strength.
Solution Approach 2:
The locking element automatically engages with the coupling sections through its locking arc sections that interact with corresponding locking sections. The device performs its own locking function without requiring additional external locking mechanisms or complex assembly procedures, thereby simplifying the overall device structure.
2Adaptability or versatility
If rigid connections are used for media-conducting lines, then connection strength is improved, but adaptability to positional changes decreases
Solution Approach 1:
The coupling device incorporates dynamic characteristics through its locking mechanism that allows for controlled movement and positioning adjustments. The locking arc sections can engage at different positions on the locking sections, enabling the connection to adapt to positional changes while maintaining sufficient connection strength through the distributed locking contact.
3Reliability
If simple locking mechanisms are used, then ease of operation is improved, but connection reliability under high pressure and temperature decreases
Solution Approach 1:
The locking element is nested within the coupling sections, with the locking arc sections positioned to interact with the locking sections of the coupling parts. This nested arrangement allows the locking mechanism to be operated simply through insertion and automatic engagement, while the distributed locking contact points ensure reliable connection under high pressure and temperature conditions.

Function Achieved in This Case
The coupling device provides a reliable, cost-effective, and easily mountable quasi-rigid connection suitable for high-pressure and temperature applications, allowing for minimal deviation compensation and easy assembly, while ensuring secure locking and simple release without tools.
Implementation Method 1
the locking element can be reversibly expanded in diameter by the inner coupling section and, due to its elastic properties, can snap back into its initial position
