Solution Overview

Problem

Existing floating pipes with larger diameters exceed the dimensions of standard shipping containers, necessitating disassembly and reassembly on-site, which is time-consuming and costly.

Innovation Solution

Designing floaters with a rounded square or squircle cross-section to fit within 40-ft ISO containers, using a combination of materials like steel, closed cell foam, and rubber, with specific dimensions to maximize floatation capacity while allowing modular connection of pipes.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If the diameter of floaters is increased to provide larger buoyancy capacity for bigger pipes, then the floatation capacity is improved, but the floaters exceed the internal dimensions of standard shipping containers requiring disassembly and reassembly

Engineering Contradiction:
Improvebuoyancy capacityVSAvoidtransportation convenience
Core Design Contradiction:
Quantity of substanceVSEase of operation

Solution Approach 1:

The floater is designed with a rounded square or squircle cross-section instead of a traditional circular cross-section. This geometric modification allows the floater to fit diagonally within standard 40-ft ISO shipping containers while maintaining sufficient buoyancy capacity. The rounded corners of the squircle shape enable the floater to navigate the rectangular container space efficiently, eliminating the need for disassembly during transportation.

Inventive Principle:
Principle #14Spheroidality (Curvature)

2Adaptability or versatility

If the diameter of floaters is increased to support larger pipe diameters, then the pipe size capability is improved, but the floaters cannot fit within standard shipping containers

Engineering Contradiction:
Improvepipe size capabilityVSAvoidshipping container fit
Core Design Contradiction:
Adaptability or versatilityVSVolume of stationary object

Solution Approach 1:

By adopting a rounded square cross-section, the floater achieves an optimal balance between external dimensions for container compatibility and internal volume for buoyancy. The squircle geometry provides a larger effective diameter along the diagonal axis to support bigger pipes while keeping the width and height dimensions within container limits.

Inventive Principle:
Principle #14Spheroidality (Curvature)

Solution Approach 2:

The invention utilizes the diagonal dimension of the rectangular shipping container by orienting the rounded square floater at an angle during loading. This allows the floater's diagonal measurement to exceed the container's width and height while still fitting within the three-dimensional space, effectively using the container's volume more efficiently.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

3Ease of operation

If floaters are divided into several smaller parts to fit within shipping containers, then the transportation feasibility is improved, but the assembly process becomes time-consuming and expensive

Engineering Contradiction:
Improvetransportation feasibilityVSAvoidassembly time
Core Design Contradiction:
Ease of operationVSLoss of time

Solution Approach 1:

The rounded square cross-section enables the complete floater to be transported as a single integrated unit within standard 40-ft ISO containers, eliminating the need for segmentation. This geometric innovation resolves the contradiction by allowing the full-sized floater to fit within container dimensions without requiring disassembly into smaller parts.

Inventive Principle:
Principle #14Spheroidality (Curvature)
