Solution Overview

Problem

The manufacture of internal platform support structures for offshore wind turbines is challenging due to the need for custom designs, skilled labor, and varying structural elements, leading to high costs and material wastage, especially when installed in remote locations.

Innovation Solution

A modular internal platform support structure assembled using specifically designed structural elements connected by fasteners, made from readily available materials like galvanized steel sheet metal, which can be easily manufactured and assembled, reducing costs and complexity.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If standard steel I-beams are welded together to form SIP structures, then structural strength and stability are improved, but manufacturing complexity and cost increase due to requiring skilled labor and custom designs

Engineering Contradiction:
Improvestructural strengthVSAvoidmanufacturing complexity
Core Design Contradiction:
StrengthVSEase of manufacture

Solution Approach 1:

The structure is divided into modular components (vertical posts, horizontal beams, platforms) that can be manufactured separately using standardized elements and assembled together using simple connectors, eliminating the need for complex welding operations while maintaining structural integrity

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The invention replaces expensive, skill-intensive welding operations with inexpensive, simple connector assemblies that can be installed by unskilled labor, significantly reducing manufacturing cost and complexity while achieving sufficient structural strength for the application

Inventive Principle:
Principle #27Cheap short-living objects (Disposable)

2Adaptability or versatility

If SIP structures are customized for each region with locally available materials, then adaptability to local conditions is improved, but supply chain complexity and maintenance consistency deteriorate

Engineering Contradiction:
Improveregional adaptabilityVSAvoidsupply chain complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The invention employs universal standardized components (uniform posts, beams, and connectors) that can be used in any location, creating a single global supply chain while allowing the same modular system to be adapted to different regional requirements through configuration rather than customization of components

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

3Reliability

If conventional welding processes are used to assemble SIP structures, then structural reliability is improved, but assembly time and labor cost increase

Engineering Contradiction:
Improvestructural reliabilityVSAvoidassembly time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The structural components are pre-assembled into modular units with connectors attached beforehand, allowing rapid on-site assembly by simply connecting the pre-prepared modules together, significantly reducing assembly time while maintaining reliability through standardized connection designs

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The connector design allows unskilled workers to assemble the structure themselves without requiring skilled welders, making the assembly process self-serviceable and dramatically reducing both labor cost and assembly time while achieving sufficient structural reliability for the application

Inventive Principle:
Principle #25Self-service
