Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If conventional crane assisted installation methods are used, then wind turbine blades can be installed, but the need for large size heavy lift cranes causes bottlenecks and delays

Engineering Contradiction:
Improveinstallation speedVSAvoidcrane size requirement
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The installation system is divided into separate functional components: a self-climbing platform for vertical transport, a blade holder for blade positioning, and a hub holder for hub assembly. This segmentation allows each component to be optimized independently and eliminates the need for a single large crane system.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The self-climbing platform performs its own vertical displacement along the tower using its climbing mechanism, eliminating the need for external crane assistance. The platform carries the blade holder and hub holder assemblies autonomously to the installation location.

Inventive Principle:
Principle #25Self-service

2Productivity

If conventional crane assisted installation methods are used, then wind turbine blades can be installed, but the need for heavy lift vessels increases environmental impact

Engineering Contradiction:
Improveinstallation capacityVSAvoidenvironmental impact
Core Design Contradiction:
ProductivityVSObject-affected harmful factors

Solution Approach 1:

The patent replaces the mechanical crane lifting system with a self-climbing platform that uses a different mechanical principle (climbing along the tower structure). This substitution eliminates the need for heavy lift vessels and large cranes, thereby reducing environmental impact from equipment operation and deployment.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

3Productivity

If blade holder elevator is used for vertical displacement, then installation efficiency improves, but device complexity increases

Engineering Contradiction:
Improveinstallation efficiencyVSAvoidelevator mechanism complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The self-climbing platform serves multiple functions: vertical transport, blade holder positioning, and hub holder positioning. By making the platform multi-functional, the patent reduces the need for separate specialized equipment, thereby managing complexity while improving efficiency.

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

Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

Function Achieved in This Case

Enables safe, efficient, and cost-effective installation and removal of wind turbine blades without the need for large cranes, reducing environmental impact and operational costs, and extending the operational window in adverse weather conditions.

Implementation Method 1

The blade holder can be based on two systems. First, a hard connection can be used for performing the vertical displacement of the blade holder elevator. The hard connection can be based on gyroscopic stability and can include a a holder based on the ability of the wind turbine blade to freely rotate from a hub end on two axes while being elevated or lowered.

Methodology Applied
Scientific EffectGyroscopic stability: Gyroscope

Implementation Method 2

Second, a flexible connection can be implemented for performing the vertical displacement of the blade holder elevator, wherein a holder allows the wind turbine blade to rotate from a hub end freely and securely on more than two axes while being elevated or lowered.

Methodology Applied
Scientific EffectFlexible connection: Elasticity
