Corrugated Pipe Coupling with Guided Clamping Ring Sealing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing corrugated pipe connection devices face challenges with sealing efficiency due to the need for manual expansion of a rigid clamping ring, which can lead to deformation, eccentric coupling, and fluid leakage, and require complex operations that increase the risk of losing the clamping ring during assembly.
Innovation Solution
A corrugated pipe connection device design where a clamping ring is temporarily coupled to a nut, with a socket featuring an outer protrusion that guides the clamping ring into a groove, allowing for simplified assembly by screwing the nut and socket together, ensuring proper alignment and sealing without manual expansion of the clamping ring.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the clamping ring is manually expanded to increase its inner diameter for insertion into the groove, then the clamping ring can be coupled to the corrugated pipe, but the clamping ring may exceed its elastic limit and fail to return to its original shape, causing deformation and sealing failure
Solution Approach 1:
The clamping ring is preliminarily expanded during the manufacturing process to a predetermined inner diameter that is larger than the groove diameter. This preliminary action eliminates the need for manual expansion during installation, preventing the clamping ring from exceeding its elastic limit during coupling operations while ensuring reliable sealing.
2Ease of operation
If the clamping ring is manually expanded during assembly, then it can be inserted into the groove, but the complex operation increases the risk of losing the clamping ring and reduces assembly efficiency
Solution Approach 1:
The clamping ring is preliminarily expanded to the required diameter during manufacturing, eliminating the need for complex manual expansion operations during assembly. This allows workers to simply install the pre-expanded clamping ring onto the corrugated pipe, significantly improving assembly efficiency and reducing the risk of losing components.
Solution Approach 2:
The invention uses a cost-effective pre-expanded clamping ring that can be mass-produced with the required expansion already applied. This eliminates the need for specialized expansion tools and complex assembly procedures, making the overall process more efficient and less prone to errors.
3Ease of manufacture
If the clamping ring is manually expanded during assembly, then it can be inserted into the groove, but the complex and difficult operation requires skilled workers and increases assembly time
Solution Approach 1:
The clamping ring is preliminarily expanded to the predetermined inner diameter during the manufacturing process. This transfers the complex expansion operation from the assembly stage to the manufacturing stage, where it can be performed efficiently using specialized equipment. During assembly, workers only need to install the pre-expanded clamping ring, significantly reducing assembly time and the skill level required.

Function Achieved in This Case
The solution enhances sealing efficiency by maintaining the clamping ring's original shape, preventing deformation and fluid leakage, and allows for easy repair by tightening the nut alone, ensuring reliable and efficient coupling and sealing without manual intervention.
Implementation Method 1
the outer protrusion is inserted into a gap between an inner circumferential surface of the nut and an outer circumferential surface of the clamping ring, the clamping ring is pressed radially inwards so that the inner portion of the clamping ring is inserted into the groove of the corrugated pipe
