Fluid Line Connector Assembly With Tool-Free Retainer Lock
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current connection joints for fluid lines require tools for tightening and can give a false sense of secure connection, leading to potential separation during fluid transfer.
Innovation Solution
A connector assembly featuring a female coupler, a male coupler, and a retainer or wire spring that securely locks the couplers together through a groove and slot mechanism, eliminating the need for tools and ensuring a reliable fluid connection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If tools such as screwdrivers are used to tighten screws that secure fluid lines together, then the connection can be securely fastened, but the operation becomes complex and requires additional tools
Solution Approach 1:
The connector assembly enables self-service connection through a self-latching mechanism. The retainer with its resilient portion automatically engages with the groove on the opposing coupler when the connectors are mated, creating a secure connection without requiring external tools or manual tightening operations.
2Ease of operation
If a simple connector design is used, then ease of operation is improved, but the reliability of the connection may be compromised leading to potential separation during fluid transfer
Solution Approach 1:
The retainer acts as an intermediary locking component between the two couplers. Its resilient portion engages with the groove to provide a positive mechanical lock that prevents separation during fluid transfer, thereby ensuring connection reliability while maintaining the simplicity of the overall connector design.
3Reliability
If a retainer mechanism with groove and slot is implemented, then connection reliability is improved by preventing separation, but the device complexity increases
Solution Approach 1:
The retainer is segmented into distinct functional portions: a resilient portion that engages with the groove to prevent separation, and an actuating portion that extends through the slot for manual operation. This segmentation allows each portion to perform its specific function efficiently while keeping the overall mechanism simple and manageable.

AI summary
A connector assembly that provides fluid communication between a first conduit and a second conduit. The connector assembly includes a first coupler, a retainer, and a second coupler. The retainer is carried by the first coupler. The second coupler has a groove. When the first and second couplers are brought together, they fluidly communicate with each other and the retainer is received with the groove so that the first and second couplers are prevented from unintentionally coming apart.
