Straight-Thread Pipe Fitting With Seal Stop for Leak-Free Joints
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Piping components with tapered threading often require adapters for connection, leading to increased labor and material costs, and potential leaks due to varying threading angles between components from different manufacturers.
Innovation Solution
A tight-seal piping component with straight internal threading and a seal stop surface, allowing for a fluid-tight connection by rotatingally engaging with other components having straight external threading, eliminating the need for adapters and ensuring consistent sealing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If adapters are used to connect piping components with different threading types, then compatibility is improved, but device complexity and material cost increase
Solution Approach 1:
The patent applies universality by designing piping components with standardized straight threading that can directly connect to other components with matching straight threading. This eliminates the need for adapter components, reducing device complexity and material costs while maintaining compatibility across the piping system.
2Adaptability or versatility
If tapered threading with varying angles is used, then connection flexibility is improved, but sealing reliability deteriorates due to improper matching between components
Solution Approach 1:
The patent changes the threading angle parameter from variable (tapered) to fixed (straight). This parameter change ensures that straight threading components from different manufacturers with standardized specifications will match properly, maintaining sealing reliability through consistent geometric parameters while preserving connection flexibility.
3Adaptability or versatility
If adapters are used to connect piping components, then material compatibility is improved, but labor time and installation cost increase
Solution Approach 1:
The patent establishes a universal connection system using straight threading that allows direct connection between compatible piping components without requiring adapter intermediaries. This universal design reduces installation time and labor costs while maintaining material compatibility across the piping system.

AI summary
Example aspects of a tight-seal piping component, a tight-seal piping assembly, and a method for preventing leaking in a piping assembly are disclosed. The tight-seal piping component can comprise a fitting body defining a fitting inner surface, a fitting outer surface opposite the fitting inner surface, a first fitting end, and a second fitting end opposite the first fitting end, the fitting inner surface defining: an interior channel defining a fitting axis; a seal stop surface within the interior channel; and internal threading between first fitting end and the seal stop surface, the internal threading defining straight threading extending in a direction about perpendicular to the fitting axis; and a seal received within interior channel and abutting seal stop surface.
