Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a complex fixing arrangement with multiple securing parts and locking mechanisms is used, then the reliability of securing the plug-in part is improved, but the device complexity and difficulty of disassembly increase
Solution Approach 1:
The fixing arrangement is divided into functionally independent components: the securing part with securing arms for initial engagement, the retaining part with retaining wings for final securing, and the actuating structure for controlled operation. This segmentation allows each component to perform its specific function efficiently while simplifying the overall disassembly process, as each segment can be operated independently.
Solution Approach 2:
The securing arms and retaining wings are designed with dynamic characteristics, allowing them to move between different positions (engaged/disengaged states). The actuating structure enables controlled pivoting and movement of these components, transforming a static complex mechanism into a dynamic system that can be easily operated and disassembled when needed.
2Manufacturing precision
If a specialized disassembly tool is required, then the precision of disassembly is improved, but the ease of operation and manufacturing cost increase
Solution Approach 1:
The actuating structure is designed to be operated directly by hand or with simple tools, allowing the fixing arrangement to be disassembled without requiring specialized equipment. The retaining wings can be manually pivoted and the securing arms released, enabling the system to serve itself in the disassembly process and eliminating the need for complex specialized tools.
Solution Approach 2:
The actuating structure serves as an intermediary mechanism between the operator and the securing components. Instead of requiring direct manipulation of the securing arms and retaining wings, the actuating structure mediates the disassembly process by coordinating their movement, thereby simplifying operator interaction while maintaining precision.
3Reliability
If multiple retaining wings and securing arms are used, then the secure engagement of the plug-in part is improved, but the ease of manufacture decreases
Solution Approach 1:
The securing part and retaining part are designed to be manufactured as integrated components where possible, reducing the total number of separate parts. The securing arms and retaining wings are configured to work together as a coordinated system, allowing for simplified manufacturing processes while maintaining the security of engagement through their cooperative function.

AI summary
The invention relates to a fluid line coupling and comprises a receiving part (1) as well as a fixing assembly (15) for the fixation of an insertion part (10). The fixing assembly has a retaining part (17) which is, in a steady state, located in the receiving space (4) of the receiving part (1) and is equipped with pivotable support wings (22, 23) engaging behind the existing front coil (14) which is located on the insertion part (10). Said fixing assembly also features a locking element (16) which is movably connected to the retaining part (17) and has, along with the receiving part (1), elements of a blocking assembly which impede the movement of the locking element (16) from an extended to a retracted position, if the insertion part (10) is not positioned accordingly. Thus, an easily attainable and stable fixation of the insertion part (10) in the receiving part (1) is achieved.
