Solution Overview

Problem

Slurry pipes in deep liquid bodies require additional buoyancy to maintain the upper end near or above the surface, but existing solutions are complex to install and do not effectively complement the outer radius of the pipe.

Innovation Solution

A buoyant device with a concaved section that complements the outer radius of the slurry pipe, attached via straps to prevent rotation and longitudinal movement, ensuring easy installation and secure attachment.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If existing buoyant devices are used to provide buoyancy for slurry pipes, then the upper end of the pipe can be kept near or above the surface, but the installation becomes complex and the devices do not effectively complement the outer radius of the pipe

Engineering Contradiction:
Improvebuoyancy effectivenessVSAvoidinstallation complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The buoyant device incorporates a concaved section with a curvature that complements the outer radius of the slurry pipe. This curved surface design allows the buoyant device to conform to the cylindrical shape of the pipe, creating a stable fit that simplifies installation while maintaining effective buoyancy support.

Inventive Principle:
Principle #14Spheroidality (Curvature)

Solution Approach 2:

The buoyant device is designed to attach to the exterior of the slurry pipe, with the concaved section nesting against the pipe's outer surface. This nested configuration allows the buoyant device to wrap around and secure to the pipe without requiring complex internal modifications or additional support structures.

Inventive Principle:
Principle #7Nested doll (Nesting)

2Reliability

If existing buoyant devices are used to provide buoyancy, then the pipe can be supported, but the devices rotate or move longitudinally during operation

Engineering Contradiction:
Improvebuoyancy supportVSAvoidpositional stability
Core Design Contradiction:
ReliabilityVSStability of the object's composition

Solution Approach 1:

The concaved section's curvature matches the pipe's outer radius, creating a snug fit that prevents rotation and longitudinal movement. This geometric complementarity ensures the buoyant device remains stationary relative to the pipe while providing continuous buoyancy support.

Inventive Principle:
Principle #14Spheroidality (Curvature)

3Reliability

If complex installation methods are used to secure buoyant devices, then the devices can be attached to the pipe, but the installation time and complexity increase

Engineering Contradiction:
Improveattachment securityVSAvoidinstallation time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The concaved section is designed to naturally conform to the pipe's outer surface geometry, allowing the buoyant device to be easily positioned and secured without requiring complex alignment procedures or specialized installation equipment, thereby reducing installation time while maintaining secure attachment.

Inventive Principle:
Principle #14Spheroidality (Curvature)
