Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Positioning and aligning large diameter pipes for tie-in is time-consuming, costly, and hazardous, requiring extensive equipment and labor, with current methods being inefficient and unsafe for workers.
Innovation Solution
An attachment for construction equipment that automates pipe end alignment using adjustable grapple mechanisms and laser guidance systems, allowing precise positioning and alignment of pipes in x, y, and z-axis directions for secure welding or processing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional manual methods are used to position and align pipe ends, then worker safety is compromised and alignment precision is insufficient, but the process becomes extremely time-consuming and labor-intensive
Solution Approach 1:
The patent replaces manual mechanical positioning with an automated system that uses laser guidance and hydraulic actuators. The laser alignment system provides precise optical references, while hydraulic cylinders automatically adjust pipe positions, eliminating the need for manual measurement and positioning operations.
Solution Approach 2:
The system enables self-alignment through automated feedback mechanisms where sensors detect pipe positions, control systems process this information, and actuators automatically make corrections. The grapple mechanisms with multiple degrees of freedom allow the system to self-adjust pipe positions without continuous human intervention.
2Reliability
If extensive equipment and multiple workers are deployed for pipe alignment, then alignment capability is improved, but operational cost and complexity increase significantly
Solution Approach 1:
The attachment device integrates multiple functions into a single unit: grapple mechanisms for pipe gripping, hydraulic actuators for positioning, laser alignment systems for guidance, and sensors for detection. This multi-functional integration replaces what would traditionally require separate equipment and multiple specialized workers.
Solution Approach 2:
The patent combines the grapple mechanism, positioning actuators, alignment system, and control electronics into an integrated attachment that mounts to existing construction equipment. This merging of functions into a single coordinated system reduces the number of separate equipment pieces and workers needed.
3Productivity
If manual pipe positioning methods are used, then equipment cost is reduced, but worker safety is compromised and operational efficiency decreases
Solution Approach 1:
The system replaces dangerous manual handling operations with automated hydraulic actuators and robotic grapple mechanisms. Workers are removed from hazardous positions near heavy pipes and moving equipment, while the automated system performs all positioning and alignment operations safely and efficiently.

AI summary
An attachment that is configured for attachment to an arm of a piece of construction equipment. The attachment includes a pair of grapple mechanisms mounted on a main beam. Each grapple mechanism includes opposing grab arms mounted to a grab arm housing. The grab arm housings of the grapple mechanisms are each individually adjustable separate from one another relative to the main beam in one or more directions generally perpendicular to the longitudinal axis of the main beam. The attachment can fine adjust the positions of the pipe ends relative to one another until the ends align with each other, at which point the pipe ends can be welded or otherwise secured to each other while being held in position by the grapple mechanisms.
