Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If spoilers or flow guiding devices are added to enhance aerodynamic properties, then energy capture efficiency is improved, but device complexity and installation complexity increase
Solution Approach 1:
The blade element is divided into a first portion for attachment to the blade surface and a second portion forming the aerodynamic feature, allowing modular installation and simplifying the overall device complexity while maintaining aerodynamic performance
Solution Approach 2:
The blade element extends perpendicular to the blade surface into a third dimension, creating a three-dimensional structure that enhances aerodynamic properties without complicating the two-dimensional blade design, thereby improving energy capture efficiency without proportionally increasing installation complexity
2Productivity
If blade elements are securely attached to improve aerodynamic performance, then energy production increases, but attachment complexity and material usage increase
Solution Approach 1:
The blade element is segmented into two portions where the first portion serves as a compact attachment interface, reducing the total material volume required while ensuring secure attachment to the blade surface for improved energy production
Solution Approach 2:
The blade element is constructed from composite materials that provide high strength-to-weight ratio, enabling secure attachment and aerodynamic performance with reduced material usage compared to traditional homogeneous structures
3Productivity
If the angle between first and second portions is optimized to enhance aerodynamic properties, then energy capture improves, but manufacturing precision requirements increase
Solution Approach 1:
The angle between the first and second portions is optimized within a specific range (90° to 180°, preferably 110° to 160°) to balance aerodynamic performance with manufacturing feasibility, allowing energy capture improvement without excessive manufacturing precision requirements
