Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing alignment tools for wind turbine rotor blades struggle to provide precise cuts through the ductile and robust leading edge protection material, leading to fraying and difficulties in repair or replacement, especially due to the uneven geometry of the blades.
Innovation Solution
An alignment tool with a flexible guiding structure and fixation means, such as suction cups, adhesive elements, or a clamp arrangement, that allows for reversible attachment and precise guidance of the cutting edge along the rotor blade's contour, enabling precise cuts without damaging the material.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a rigid guiding structure is used for precise cutting, then cutting precision is improved, but adaptability to different blade geometries deteriorates
Solution Approach 1:
The patent employs a flexible belt as the guiding structure instead of a rigid one. This flexible belt can conform to various blade geometries and contours while still providing precise guidance for the cutting edge. The flexibility allows the belt to adapt to different radii of curvature and blade shapes, resolving the contradiction between maintaining cutting precision and adapting to diverse geometries.
Solution Approach 2:
The guiding structure is made dynamic and adjustable through the flexible belt design. The belt can be tensioned and positioned to match different blade configurations, allowing the system to adapt its shape while maintaining functional precision for cutting operations across various geometries.
2Stability of the object's composition
If the alignment tool is firmly attached to the workpiece, then stability during cutting is improved, but ease of removal and repositioning deteriorates
Solution Approach 1:
The fixation means employs adjustable clamping elements that can be dynamically tightened to secure the flexible belt to the blade during cutting operations, providing stability. After cutting, the clamping elements can be easily loosened and the tool removed or repositioned, resolving the contradiction between stability during operation and ease of repositioning.
3Adaptability or versatility
If the guiding structure is made flexible to adapt to contours, then adaptability to geometry is improved, but structural strength deteriorates
Solution Approach 1:
The flexible belt is designed with appropriate material properties and cross-sectional characteristics to provide both flexibility for contour adaptation and sufficient structural strength to guide the cutting edge accurately. The belt's construction balances these competing requirements through material selection and dimensional design.
Solution Approach 2:
The flexible belt may utilize composite material construction combining materials with different properties to achieve both flexibility and strength. This allows the guiding structure to conform to blade contours while maintaining the structural integrity needed for precise cutting guidance.
