Modular Strand Guide Inserts for Wind Turbine Cable Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fastening systems for securing strand elements in wind power installations are costly and complex due to the base body needing to form and support strand passages, requiring large format tools and elaborate manufacturing processes.
Innovation Solution
The system uses independent inserts with locking devices and locking elements to form strand passages, allowing the base body to solely function as a support, enabling simpler and cost-effective manufacturing with modular components adaptable to various strand sizes and shapes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the base body forms the strand passages directly, then the strand passages are integrated into the base body structure, but the manufacturing becomes elaborate and cost-intensive requiring large format tools
Solution Approach 1:
The base body is divided into two functional parts: the base body itself and separate inserts. The inserts contain the strand passages and are locked into the base body. This segmentation allows the base body to be manufactured simply as a support structure, while the inserts are manufactured separately with the required passage geometries, avoiding the need for large format tools and elaborate manufacturing processes.
Solution Approach 2:
The strand passages are extracted from the base body structure and placed into separate inserts. These inserts are then locked into the base body, separating the function of providing structural support (base body) from the function of forming passages (inserts). This extraction simplifies base body manufacturing while maintaining the integrated functionality.
2Adaptability or versatility
If the base body supports and forms strand passages, then the base body must be designed with complex geometry, but this increases manufacturing costs and requires large format tools
Solution Approach 1:
Different insert designs with varying passage geometries can be developed to accommodate different strand sizes and shapes, while the base body remains a simple, standardized support structure. This segmentation allows adaptability to be achieved through insert variation rather than base body redesign.
Solution Approach 2:
The base body is designed as a universal support structure that can accommodate multiple types of inserts with different passage configurations. This multi-functionality is achieved through the standardized locking mechanism that accepts various insert designs, allowing the same base body to serve multiple application purposes.
3Reliability
If the base body is designed to form strand passages, then the passages are permanently integrated, but this reduces manufacturing efficiency and increases costs
Solution Approach 1:
The inserts with strand passages are prepared in advance as separate components, allowing for pre-manufacturing and quality control. These pre-prepared inserts are then quickly locked into the base body, separating the complex passage formation process from the final assembly, thereby improving overall manufacturing efficiency.
Solution Approach 2:
By segmenting the base body and inserts as separate manufacturable components, each can be optimized for its specific manufacturing process. The inserts can be manufactured using appropriate techniques for their geometry, while the base body is manufactured independently, allowing for parallel production and improved productivity.

AI summary
A system guides and secures the position of strand elements, such as cables, hoses or tubes, in particular in wind power installations. The system includes a base body (1) that forms at least one strand passage with a receiving space (19) for at least one strand element. The respective strand passages are formed by inserts (3) in the form of independent components. A locking device with a locking element (25) forms a form-fitting latching of each insert (3) on the base body (1).
