Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for aligning and supporting flanges in piping systems are often cumbersome, prone to inaccuracies, and require multiple fixtures for different sizes, leading to inefficiencies and safety hazards, especially when dealing with larger flanges or those in confined spaces.
Innovation Solution
A flange leveling system utilizing U-shaped spring-loaded wires with stainless-steel spherical ball bearings that securely seat in flange bolt holes, allowing for precise alignment and level indication, reducing the risk of distortion and making the process easier and faster, even in challenging conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional two-holing alignment method is used, then alignment can be achieved, but measurement precision deteriorates due to bolt tilting and cocking
Solution Approach 1:
The patent introduces ball bearings as intermediary elements between the bolts and the level device. These ball bearings provide stable, distortion-free support surfaces for the level device, eliminating the tilting and cocking problems associated with direct bolt support. The ball bearings act as mediators that transfer the alignment function from the bolts to a more reliable support mechanism.
Solution Approach 2:
The patent replaces the traditional mechanical support system (level device directly on bolts) with a hybrid system incorporating spherical elements (ball bearings). This substitution eliminates the mechanical instability caused by bolt flexibility and clearance, providing a more precise and reliable alignment reference surface.
2Adaptability or versatility
If multiple fixtures are used for different flange sizes, then adaptability improves, but device complexity increases
Solution Approach 1:
The patent creates a universal alignment system where ball bearings can be used with flanges of various sizes. The ball bearings serve multiple functions: they support the level device, provide alignment references, and can be positioned in different bolt holes regardless of flange size. This single versatile component replaces the need for multiple size-specific fixtures.
Solution Approach 2:
The patent divides the alignment system into separable components (ball bearings that can be independently positioned in different flange configurations). This segmentation allows the same basic components to be reconfigured for different flange sizes, reducing the need for complete fixture sets for each size.
3Ease of operation
If workers use smaller bolts for convenience, then ease of operation improves, but manufacturing precision deteriorates due to increased tilting
Solution Approach 1:
The ball bearings serve as intermediaries that decouple the bolt size from the alignment precision. Workers can use smaller, easier-to-insert bolts, while the ball bearings maintain precise alignment by providing stable support surfaces for the level device, independent of bolt dimensions.

AI summary
A pipe flange is leveled for welding by using stainless steel using ball bearings attached to a U-shaped spring-loaded wire so a fitter is able to level a flange for welding while the wire supports a level. The ball bearings are part of a first leveling unit and a second leveling unit which comprise a flange leveling system. The spring acts to bias a first leg and a second leg of the leveling units such that the distal ends of both legs are biased toward each other. The ball bearings are axially co-linear with each other and are sized to be seated in bolt holes defined in the first and second sides of the pipe flange. A related process is also disclosed wherein the flange is adjusted until the associated flange holes on the first and second sides of the pipe flange are level with each other.
