Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If components are fixed onto one part of the rotating system by means of bolting, welding, or soldering, then a tight connection is obtained between the component and the attached part, but it becomes difficult to retrofit the component in an existing wind turbine
Solution Approach 1:
The patent replaces traditional mechanical attachment methods (bolting, welding, soldering) with a magnetic attachment system. The component includes magnetic elements that magnetically attach to the rotating system part, eliminating the need for permanent mechanical fastening while maintaining a tight connection. This allows for easy installation and removal, enabling retrofitting in existing wind turbines without complex assembly processes.
2Reliability
If components are fixed onto one part of the rotating system, then the component is securely attached, but it cannot easily slide along another part of the rotating system in tight abutment
Solution Approach 1:
The patent employs a dynamic attachment system where the component can be securely held in position by magnetic forces while simultaneously being able to slide along the surface of the rotating system. The magnetic attraction provides secure attachment perpendicular to the surface, while the component's design allows parallel movement along the surface, combining both secure attachment and sliding capability.
3Reliability
If traditional mechanical attachment methods are used, then the component is firmly fixed, but the installation process becomes complex and time-consuming
Solution Approach 1:
The patent replaces complex mechanical attachment processes with a simple magnetic attachment mechanism. The component includes magnetic elements that can be easily positioned and attached to the rotating system by simply bringing them into proximity, eliminating the need for bolting, welding, or soldering operations. This dramatically reduces installation time while maintaining firm fixation through magnetic forces.
