Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional no hub clamps with bands are used to connect pipes, then the connection can be achieved, but the device becomes complex and difficult to manufacture and use
Solution Approach 1:
The clamp is divided into distinct functional segments: the elongated band for circumferential engagement, the locking mechanism for securing the band ends, and the gasket for sealing. This segmentation allows each component to be optimized independently, simplifying manufacturing while maintaining connection reliability.
Solution Approach 2:
The invention extracts the essential function of pipe connection from the complex traditional clamp design, isolating it into a simplified system comprising only the necessary elements: band, locking mechanism, and gasket. This eliminates unnecessary components while preserving the core connection functionality.
2Reliability
If traditional no hub clamps with bands are used to connect pipes, then the connection can be achieved, but the device becomes difficult to use
Solution Approach 1:
The locking mechanism is designed to automatically secure the band ends together through self-engaging features, eliminating the need for complex assembly procedures or specialized tools. The mechanism performs its own locking function, making installation straightforward and improving ease of operation.
Solution Approach 2:
The locking mechanism combines multiple functions into a single integrated component that simultaneously secures the band ends, maintains tension, and provides a locked configuration. This merging of functions reduces the number of steps required for installation and improves user convenience.
3Reliability
If a locking mechanism is added to secure the band ends, then the connection reliability improves, but the manufacturing complexity increases
Solution Approach 1:
The elongated band is designed as a flexible element that can be easily formed and shaped during manufacturing. This flexibility allows the band to be produced using simple forming processes, offsetting the added complexity of the locking mechanism and maintaining ease of manufacture.
Solution Approach 2:
The clamp system combines different materials with complementary properties: the band uses flexible material for engagement, the locking mechanism uses rigid material for structural integrity, and the gasket uses sealing material for leakage prevention. This composite approach allows each component to be manufactured using processes suited to its specific material properties.

Implementation Method 1
the membrane section is configured to collapse in response to radial compression of the gasket about a pipe end
Implementation Method 2
radial compression of the gasket about a pipe end
Implementation Method 3
The wedge may have a first portion and a second portion, with the first portion configured to contact the seal and prevent radial movement of the seal

AI summary
Systems, devices and methods for pipe connectors and associated components are disclosed. Features for no hub clamps, for locking mechanisms on no hub clamps, for tools for no hub clamps, and for gaskets are described. The gaskets may be hourglass-shaped or otherwise taper outward near the ends to facilitate assembly onto pipe ends and that compress inward when a clamp is secured over the gasket. The gaskets may reduce in circumference at the gasket ends upon contraction of the gasket by a clamp onto two pipe ends. The gaskets may include collapsible sections that collapse upon contraction of the gasket by a clamp onto two pipe ends. The gaskets may include wedges at the collapsible regions that extend axially and protrude into the channel.
