Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Power

If wind turbines increase in size and power output, then power generation capability is improved, but transportation and handling costs increase and design complexity increases

Engineering Contradiction:
Improvepower outputVSAvoiddesign complexity
Core Design Contradiction:
PowerVSDevice complexity

Solution Approach 1:

The nacelle is divided into multiple modular units (main unit and auxiliary units) that can be independently manufactured, transported, and assembled. Each unit houses specific components, allowing the overall system to achieve high power output capabilities while maintaining manageable design complexity through standardized modular architecture.

Inventive Principle:
Principle #1Segmentation

2Power

If wind turbines increase in size and power output, then power generation capability is improved, but transportation costs increase

Engineering Contradiction:
Improvepower outputVSAvoidtransportation costs
Core Design Contradiction:
PowerVSQuantity of substance

Solution Approach 1:

The nacelle is divided into multiple modular units (main unit and auxiliary units) that can be independently manufactured, transported, and assembled. Each unit houses specific components, allowing the overall system to achieve high power output capabilities while maintaining manageable design complexity through standardized modular architecture.

Inventive Principle:
Principle #1Segmentation

3Adaptability or versatility

If custom configurations are created to meet specific power requirements, then adaptability is improved, but manufacturing complexity increases

Engineering Contradiction:
Improveconfiguration adaptabilityVSAvoidmanufacturing ease
Core Design Contradiction:
Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The main unit and auxiliary units are designed with standardized interfaces and connection mechanisms that can accommodate different component configurations. This universal modular platform allows the same basic unit designs to be adapted for various power requirements and operational conditions without requiring custom manufacturing for each configuration.

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

4Ease of repair

If maintenance accessibility is improved, then ease of repair is improved, but structural complexity increases

Engineering Contradiction:
Improvemaintenance accessibilityVSAvoidstructural complexity
Core Design Contradiction:
Ease of repairVSDevice complexity

Solution Approach 1:

The nacelle is divided into multiple modular units (main unit and auxiliary units) that can be independently manufactured, transported, and assembled. Each unit houses specific components, allowing the overall system to achieve high power output capabilities while maintaining manageable design complexity through standardized modular architecture.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The auxiliary units can be detached from the main unit, allowing maintenance personnel to access and service components housed within the auxiliary units without disassembling the entire nacelle structure. This extraction capability significantly improves maintenance accessibility while adding minimal structural complexity through standardized connection interfaces.

Inventive Principle:
Principle #2Taking out (Extraction)

AI summary

A set of units for assembly to form a wind turbine nacelle. The nacelle comprises a rotor-supporting assembly and generator, and a power conversion assembly and the set of units comprises a main unit arranged to be connected to a wind turbine tower and housing the rotor-supporting assembly and the generator, and at least two different auxiliary units each housing an operative component forming part of the power conversion assembly. To allow different wind turbine configurations, one of the auxiliary units can be selected from the at least two auxiliary units and assembled with the main unit to form the nacelle.
