Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pipe welding methods face challenges due to improper alignment and the need for manual handling, which can lead to misalignment and injuries from heat exposure, especially when dealing with varying pipe sizes and angles.
Innovation Solution
An adjustable pipe alignment tool comprising a pipe guide, guide shaft, adapters, and a chain system that allows for precise alignment and secure holding of pipe ends during welding, eliminating the need for manual handling and accommodating different pipe sizes and angles through adjustable mechanisms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual holding of pipe fittings during welding is used, then the user has direct control over positioning, but the user is exposed to heat injury and alignment accuracy deteriorates
Solution Approach 1:
The patent introduces a pipe alignment tool as an intermediary device between the welder and the pipe fittings. This tool includes clamping mechanisms that securely hold the fittings in proper alignment during welding, eliminating the need for manual holding and thus preventing heat injury while maintaining alignment accuracy
Solution Approach 2:
The alignment tool is divided into separate functional components: clamping mechanisms for securing fittings, alignment guides for maintaining proper positioning, and adjustment mechanisms for accommodating different pipe sizes and angles. This segmentation allows each component to perform its specific function effectively
2Adaptability or versatility
If fixed pipe alignment tools are used, then the structure is simple, but the tools cannot accommodate varying pipe sizes and angles
Solution Approach 1:
The patent employs adjustable and movable components in the alignment tool, including adjustable clamping arms that can be positioned at different angles and distances, and movable alignment guides that can be repositioned along the pipe length. This dynamic design allows the tool to adapt to various pipe sizes and angles while maintaining a relatively simple overall structure
Solution Approach 2:
The alignment tool incorporates parameters such as adjustable arm lengths, variable clamping forces, and repositionable alignment guides that can be modified to match different pipe dimensions and angular requirements. These parameter changes enable the tool to handle diverse piping configurations without requiring multiple specialized tools
3Ease of operation
If existing pipe alignment tools are used, then alignment can be achieved, but the tools are difficult to use and interfere with the welding process
Solution Approach 1:
The patent designs the alignment tool with removable and separable components that can be easily attached and detached from the pipe fittings. The clamping mechanisms and alignment guides can be quickly installed and removed without interfering with the welding process, improving ease of operation while maintaining necessary functionality
Solution Approach 2:
The alignment tool incorporates self-adjusting features such as automatic alignment guides that self-position on the pipe, and clamping mechanisms that self-lock into place. These self-service features reduce the complexity of operation by eliminating the need for complex manual adjustments and interventions during the welding process

AI summary
An alignment tool that is used to hold a pipe fitting stationary in the welding process includes a pipe guide, a guide shaft, and an adapter. The adapter can vary according to the fitting that is to be welded. As an example, the adapter can be a flange adapter, a 90-degree adapter or a 45-degree adapter. The guide shaft is slidably engaged to a connecting arm which is perpendicularly and terminally fixed to the pipe guide. Therefore, the distance between the guide shaft and the pipe guide can be varied as preferred. A base section of the adapter is slidably engaged along the guide shaft. Therefore, the position of the fitting which is mounted on the adapter can also be repositioned as preferred. In order to hold the pipe against the pipe guide, a chain is being used.
