Segmented Pipe Clamp Structure for Even Circumferential Pressure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pipe clamping arrangements cause uneven pressure distribution on pipes, leading to deformation and compromised connection tightness, as the clamping rings often result in elliptical cross-sections instead of maintaining a circular shape, which affects the integrity of the connection.
Innovation Solution
A pipe clamp design featuring a clamping section with slots that distribute force evenly around the circumference, allowing the clamping section to lie completely against the pipe, and a connecting section that can be sheared off during compression to ensure even force distribution and prevent deformation, along with orientation elements for proper alignment and a latching connection for assembly facilitation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a traditional clamping ring with an ear gap is used to tighten the pipe connection, then the clamping force is applied to close the gap, but the pressure distribution becomes uneven causing the pipe to deform into an elliptical cross-section
Solution Approach 1:
The clamping section is divided into multiple segments by slots that extend along the central axis, creating multiple clamping tabs. This segmentation allows the clamping force to be distributed evenly around the circumference, preventing localized deformation while maintaining overall connection tightness
Solution Approach 2:
The clamping section is designed with slots positioned specifically in the annular section area, creating local structural features that enable even force distribution. The slots are strategically located to ensure clamping tabs contact the pipe uniformly without affecting the ear compression mechanism
2Reliability
If the clamping section is designed to lie completely against the pipe for even force distribution, then connection tightness improves, but the structure becomes more complex requiring slots and connecting sections
Solution Approach 1:
The connecting section is designed with a predetermined breaking point that allows it to be sheared off during the compression process. This preliminary design feature enables the clamping section to separate from the holding section automatically when the ear is compressed, ensuring the clamping section lies completely against the pipe without requiring additional complex mechanisms
Solution Approach 2:
The connecting section automatically shears off during compression due to the applied force, without requiring external intervention or additional components. This self-service mechanism simplifies the overall structure by eliminating the need for separate release mechanisms or complex assembly procedures
3Shape
If slots are added to the clamping section to distribute force evenly, then pipe deformation is prevented, but manufacturing complexity increases
Solution Approach 1:
The slots are designed to extend along the central axis of the clamping ring, following a curved path that matches the circular geometry. This curved slot design distributes force evenly around the circumference while being manufacturable using standard forming processes, avoiding the need for complex multi-step manufacturing operations

Function Achieved in This Case
The solution ensures even force distribution around the pipe circumference, preventing deformation and enhancing the tightness of the connection while preventing material loss and facilitating assembly.
Implementation Method 1
the compression of the slots prevents material from the pipe from flowing away in the radial direction in the area of the clamping section
Implementation Method 2
the connecting section being designed in such a way that it allows the clamping section to be sheared off from the holding section during the compression process

AI summary
The clamp (1) has a clamping ring (4) comprising an annular section along the periphery. A lug extends radially outwards, and compressed by a tool. A lock ring (7) is compressed by the clamping ring, and partially extends into the annular section with a locking section (8). The locking section has a slot, and completely encases a pipe (2), where clearance of the slot is repealable in a pressed condition of the clamping ring. The clamping ring has a holding section (10) that stays in connection with the locking section over a connection section (11).
