Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Quick connectors for fluid conduits face difficulties in assembly due to limited accessibility and require specialized latching components with high assembly forces, especially in high-pressure applications like oil cooling and brake connections, which demand strong latching integrity and sealing reliability.
Innovation Solution
An in-line quick connector design featuring a male and female connector body with resilient latching arms and key members that allow for easy assembly using moderate forces without specialized tools, utilizing a bifurcated tubular member with elastic latching arms and anti-rotation key members for secure locking and sealing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If specialized latching components with high latching forces are used to ensure strong latching integrity and sealing reliability in high-pressure applications, then connection reliability is improved, but assembly difficulty increases and accessibility requirements become more stringent
Solution Approach 1:
The latching arms are designed as resilient elements that can dynamically deflect during assembly and then lock into position. This dynamic behavior allows the connector to be assembled with moderate forces while still achieving strong latching integrity once locked, resolving the contradiction between high reliability and ease of assembly.
Solution Approach 2:
The patent changes the physical state of the latching mechanism from rigid to resilient/elastic. By using resilient latching arms that can flex and recover, the system achieves both easy assembly (moderate forces required) and high reliability (strong locking capability), as the resilient material properties allow controlled deformation during assembly followed by secure engagement.
2Strength
If conventional quick connectors with difficult-to-handle latching elements are used, then latching strength is maintained, but accessibility requirements increase and assembly becomes difficult in limited spaces
Solution Approach 1:
The patent introduces a new dimensional aspect to the latching mechanism by using resilient arms that deflect in a direction perpendicular to the assembly force. This allows the latching action to occur in multiple dimensions, enabling assembly in tight spaces while maintaining latching strength, as the resilient deflection provides the necessary mechanical advantage without requiring large linear movements.
3Reliability
If high latching forces are required for secure connection, then connection reliability is improved, but the complexity of the latching mechanism increases
Solution Approach 1:
The resilient latching arms are designed to be self-actuating during assembly. As the male connector is inserted into the female connector, the resilient arms automatically deflect and then lock into position without requiring external actuation or complex control mechanisms. This self-service approach achieves reliable connection while minimizing mechanism complexity.

AI summary
An in-line quick connector has a female connector body arranged to receive a male connector body in an interior cavity. The male connector body includes a bifurcated tubular member that includes resilient latching arms co-operable to engage latching members located within the interior cavity of the female connector body. The male connector body and female connector body each further include a raised annular flange. Fixed key members located on the male connector body flange engage slots located on the female connector body flange.
