Adjustable Service Saddle Sealing for Variable-Diameter Pipelines
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pipeline connection systems, such as service saddles and tapping sleeves, lack flexibility and adjustability to accommodate pipes of varying diameters and do not provide efficient sealing mechanisms under high fluid pressures.
Innovation Solution
A system comprising a service saddle with a strap coupled by an over-center latch and an adjustment mechanism, allowing independent adjustment of dimensions, and featuring a hydrostatic gasket for sealing up to 300 psi, along with interchangeable outlet components and a ratchet mechanism for secure attachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed-diameter service saddle is used, then the connection structure is simple, but it cannot accommodate pipes of varying diameters
Solution Approach 1:
The service saddle incorporates an adjustable strap with modification features that allow the connection structure to change its configuration dynamically. The strap can be adjusted to different positions and configurations to accommodate various pipe diameters, transforming a static structure into a dynamic one that adapts to different conditions.
Solution Approach 2:
The connection structure is divided into separable components including the strap, modification features, and attachment mechanisms. This segmentation allows individual components to be adjusted or modified independently, enabling the overall structure to adapt to different pipe diameters while maintaining structural integrity.
2Reliability
If conventional sealing mechanisms are used, then the structure is simple, but sealing effectiveness under high fluid pressure is insufficient
Solution Approach 1:
The sealing mechanism utilizes a hydrostatic gasket that changes its sealing parameters in response to fluid pressure. As pressure increases, the gasket deforms and increases its contact pressure with the mating surface, enhancing the seal rather than deteriorating it. This parameter change allows reliable sealing under high pressure without requiring complex additional components.
3Adaptability or versatility
If the strap connection is fixed, then the attachment is secure, but the dimension cannot be adjusted for different applications
Solution Approach 1:
The strap connection transitions from a fixed state to a dynamic, adjustable state through the modification features. These features allow the strap to be repositioned or reconfigured while maintaining secure attachment, enabling dimension adjustment without compromising the security of the connection.
4Adaptability or versatility
If interchangeable outlet components are added, then versatility is improved, but device complexity increases
Solution Approach 1:
The service saddle is designed with universal attachment features and standardized interfaces that allow different outlet components to be interchangeably mounted. The modification features and strap system provide a universal mounting platform that can accommodate various outlet types, reducing the need for multiple specialized components and simplifying the overall system architecture.

AI summary
A system coupled to a pipeline includes a first portion and a second portion coupled to the first portion by an over-center latch and a secondary adjustment mechanism such that a diameter of the system can be adjusted independently by either the over-center latch or the secondary adjustment mechanism. The first portion may be coupled to the second portion by a ratchet mechanism. The system may include a service saddle or a tapping sleeve. The system may be coupled to a water main.
