Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing quick pipe connectors fail to securely retain pipes under high-pressure fluid flow, leading to accidental detachment.
Innovation Solution
A quick pipe connector design featuring a coupling sleeve that reinforces catching claws, combined with an inner and outer sealing ring system, a biasing ring, a securing ring, and an engaging member with catching claws, ensures secure retention of pipes even under high pressure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a simple engaging mechanism is used, then ease of operation is improved, but reliability deteriorates under high pressure
Solution Approach 1:
The engaging member is segmented into multiple catching claws (at least three) that are distributed around the circumference, allowing the pipe to be engaged at multiple points simultaneously. This segmentation provides both ease of insertion and reliable retention under pressure, as the distributed claws share the load and prevent accidental detachment.
Solution Approach 2:
The catching claws are designed with differentiated local qualities: they have a curved engagement surface for easy pipe insertion, a locking surface for secure retention, and varying lengths to engage different portions of the pipe. This local differentiation allows the same component to provide both ease of operation and high-pressure reliability.
2Reliability
If the catching claws are made more robust to prevent deformation, then reliability is improved, but device complexity increases
Solution Approach 1:
The coupling sleeve integrates multiple functions into a single component: it reinforces the catching claws, retains the sealing rings, and provides structural support. This merging prevents catching claw deformation without requiring separate reinforcement components, thus maintaining reliability while controlling complexity.
Solution Approach 2:
The coupling sleeve and catching claws are designed to work as a composite structural system where the rigid coupling sleeve provides external support to the more flexible catching claws. This composite approach allows the catching claws to be sufficiently robust for high-pressure reliability while maintaining the overall structural integrity without excessive complexity.
3Reliability
If multiple sealing rings are added to prevent leakage, then reliability is improved, but device complexity increases
Solution Approach 1:
The coupling sleeve serves as both a structural reinforcement element and a retention mechanism for the sealing rings. By merging the reinforcement and sealing retention functions into a single component, the design achieves reliable sealing through multiple rings without proportionally increasing device complexity.
Solution Approach 2:
The coupling sleeve is designed as a multi-functional component that simultaneously reinforces the catching claws, retains the sealing rings, and provides structural support. This universality allows multiple sealing rings to be incorporated into the design without requiring separate retention mechanisms for each ring, thus improving sealing reliability while controlling complexity.

Function Achieved in This Case
The design effectively minimizes the chance of pipe detachment by securely biasing and retaining the sealing and engaging components between the connector body and the coupling sleeve, even when subjected to high-pressure fluids.
Implementation Method 1
a biasing ring sandwiched between the inner sealing ring and the outer sealing ring; a securing ring attached to the connecting portion of the connector body in such a manner that the securing ring is arranged to bias against the outer sealing ring

AI summary
A quick pipe connector includes a connector body, an inner sealing ring, an outer sealing ring, a biasing ring sandwiched between the inner sealing ring and the outer sealing ring, a securing ring attached to a connecting portion of the connector body, an engaging member arranged to bias against the securing ring and includes a plurality of catching claws, and a coupling sleeve. The coupling sleeve includes a main sleeve member having a through hole, and an extension sleeve extending from the main sleeve member to engage with the connecting portion of the connector body. When the pipe is inserted in the connector body, the inner sealing ring, the outer sealing ring, the biasing ring, the securing ring and the engaging member are securely biased and retained between the connector body and the main sleeve member.
