Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual visual inspection and manual percussions are used for blade detection, then the detection method is simple and easy to operate, but the detection accuracy is limited and can only distinguish damage on blade surface
Solution Approach 1:
The patent replaces manual visual inspection and manual percussions with an automated detector system that includes ultrasonic detection devices, infrared imaging detection devices, or thermal imaging detection devices. The detector is mounted on a movable platform with linear tracks and sliders, eliminating manual operation while significantly improving detection accuracy through non-destructive testing technologies.
Solution Approach 2:
The patent introduces a detector as an intermediary tool between the inspector and the blade surface. The detector contacts the blade surface through adjustment rotating pads and moves along linear tracks, serving as a mediator that performs precise non-destructive detection, thereby improving detection accuracy while maintaining operational simplicity through automated control.
2Adaptability or versatility
If detectors are held by people for large blade detection, then the detection method is flexible, but it is difficult to move accurately and regularly on the surface of a large area
Solution Approach 1:
The patent divides the detection system into modular components: a supporting frame with multiple aluminum extruded frames, adjustment rotating pads for surface adaptation, a linear track system with sub-tracks and sliders, and a movable platform with detector. This segmentation allows each component to perform its specific function while maintaining overall system flexibility and positioning accuracy.
Solution Approach 2:
The patent employs dynamic elements including adjustment rotating pads that can rotate to adapt to blade surface curvature, and a movable platform that can move along linear tracks in longitudinal and lateral directions. These dynamic components enable the detector to maintain accurate contact with the blade surface while moving regularly across large areas, combining flexibility with positioning precision.
3Measurement precision
If non-destructive detection technologies are used for blade detection, then the detection accuracy is improved, but the availability, stability and operational efficiency of wind turbines need to be improved
Solution Approach 1:
The patent enables continuous detection operation through an automated movable platform that systematically moves along linear tracks covering the entire blade surface. The detector maintains continuous contact with the blade surface through adjustment rotating pads, eliminating gaps in detection and allowing uninterrupted scanning, thereby improving operational efficiency while maintaining high detection accuracy.
Solution Approach 2:
The detection system is designed to be self-contained and autonomous, with the movable platform automatically moving along predefined linear tracks and the detector automatically adapting to the blade surface through rotation of adjustment pads. This self-service capability eliminates the need for continuous manual intervention, improving operational efficiency while maintaining consistent detection accuracy across the entire blade surface.
