Solution Overview

Problem

Existing devices for aligning pipe sections during welding lack efficient mechanisms for adjusting longitudinal and lateral positions, as well as varying the orientation of end faces, which can lead to inaccuracies in joining processes.

Innovation Solution

The apparatus employs a combination of clamp members, hinges, and turnbuckle assemblies with color-coded clevises and threaded rods to adjust the longitudinal and lateral spacing between clamp jaws, allowing for precise alignment and orientation of pipe sections, including the use of shoe inserts for adapting to different pipe diameters.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If existing alignment devices are used, then basic pipe section alignment is achieved, but adjustment precision for longitudinal and lateral positions is insufficient

Engineering Contradiction:
Improvealignment precisionVSAvoiddevice structure
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The apparatus employs adjustable turnbuckle assemblies that allow dynamic modification of the spacing between clamp jaws, enabling precise longitudinal and lateral positioning of pipe sections. The hinges provide dynamic angular adjustment capability, transforming a static alignment device into a dynamically adjustable system that achieves high precision without excessive complexity.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The invention changes key geometric parameters of the alignment apparatus through adjustable mechanisms. The turnbuckle assemblies modify the longitudinal spacing parameter between clamp jaws, while the hinges enable angular orientation parameter changes. This parametric adjustability allows precise control of pipe section positioning while maintaining a relatively simple device structure.

Inventive Principle:
Principle #35Parameter changes

2Ease of operation

If multiple separate tools are used for alignment adjustments, then comprehensive positioning control is achieved, but operational efficiency decreases

Engineering Contradiction:
Improveoperational efficiencyVSAvoidapparatus integration
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The apparatus merges multiple alignment and adjustment functions into a single integrated device. The clamp members, hinges, and turnbuckle assemblies work together as a unified system that simultaneously provides longitudinal positioning, lateral positioning, and angular orientation adjustment. This consolidation eliminates the need for multiple separate tools, improving operational efficiency while the modular design keeps the overall apparatus complexity manageable.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The alignment apparatus is designed with multi-functionality, where the same device structure performs multiple functions: clamping pipe sections, adjusting longitudinal position, adjusting lateral position, and controlling angular orientation. This universal design allows a single apparatus to replace several specialized tools, enhancing ease of operation without requiring excessively complex device architecture.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Adaptability or versatility

If fixed clamp spacing is used, then device simplicity is maintained, but adaptability to different pipe configurations is limited

Engineering Contradiction:
Improvepipe configuration adaptabilityVSAvoidadjustment mechanism
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The turnbuckle assemblies provide dynamic adjustability of the longitudinal spacing between clamp jaws, allowing the device to adapt to different pipe configurations and sizes. This dynamic parameter modification capability enables the same apparatus to work with various pipe diameters and spacing requirements without requiring multiple fixed-spacing devices, thereby enhancing adaptability while maintaining reasonable structural simplicity.

Inventive Principle:
Principle #15Dynamics
