Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a permanent fixing mechanism is added to secure the socket pipe connection axially, then axial security is improved, but thermal expansion compensation capability deteriorates
Solution Approach 1:
The clamping device employs a deformation element that can dynamically adjust its clamping force. In the assembled state, the deformation element is compressed between the half-rings, creating an adhesive compression force that secures the pipe axially. However, this clamping force is not rigid but rather a controlled adhesive force that allows for limited thermal expansion while maintaining axial security.
2Reliability
If a complex multi-part clamping device is used to secure the socket pipe connection, then axial security is improved, but device complexity increases
Solution Approach 1:
The invention merges multiple functions into a single integrated clamping device. The two half-rings with complementary locking elements form a complete clamping structure that simultaneously provides axial securing, radial clamping, and positioning functions. The deformation element is integrated within the clamping groove, combining the clamping and securing functions in one compact device.
Solution Approach 2:
The clamping device is segmented into two identical half-rings that can be easily assembled and disassembled. Each half-ring has locking elements at its ends that interlock with the complementary half-ring, allowing for simple assembly while maintaining structural integrity. This segmentation reduces assembly complexity compared to a single complex piece.
3Reliability
If a deformation element is used to provide adhesive compression, then axial security is improved, but manufacturing precision requirements increase
Solution Approach 1:
The deformation element's physical state is changed from a free form to a compressed state within the clamping groove. By controlling the compression between the half-rings, the deformation element generates adhesive compression force without requiring extremely tight manufacturing tolerances. The parameter change from uncompressed to compressed state creates the necessary securing force.

AI summary
The invention relates to a clamping device (14) for axially securing a socket pipe connection (20) of two pipelines (21, 22), in particular exhaust pipes, comprising two half-rings (01) which have mutually complementary locking elements (08) at their respective ends (07) in the circumferential direction (U) and which have on an inner side in the axial direction (A) a socket groove (03) extending in the circumferential direction (U) for gripping a socket section (23) of a pipe socket and a clamping groove (04) also extending in the circumferential direction (U) at one end, wherein a deformation element (05) is partially received in the clamping device in such a way that, in the unassembled state, it projects radially inwards beyond the groove walls (06, 13) that laterally limit the clamping groove (04) in the axial direction.
