Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cable guiding systems in wind turbines suffer from increased wear, large space requirements, and complex arrangements due to cable torsion and length differences, leading to potential damage and inefficient use of tower space.
Innovation Solution
A cable guiding structure with a horizontal movement element that allows cables to move horizontally within the tower, compensating for torsion and length differences, reducing wear, and optimizing space usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a cable loop is used to compensate cable torsion and length differences, then cable damage is reduced, but space requirements increase and device complexity increases
Solution Approach 1:
The patent applies the dynamics principle by introducing a horizontal movement element that can move horizontally within the tower to compensate for cable torsion and length differences. This dynamic adjustment mechanism replaces the static cable loop arrangement, allowing the cable guiding structure to adapt to cable movements without requiring large fixed spaces for loops, thereby reducing both space requirements and device complexity while maintaining cable protection
Solution Approach 2:
The patent implements dimensionality change by enabling the cable guiding structure to move in the horizontal dimension rather than relying on vertical cable loops. The horizontal movement element translates cable compensation from a vertical space-consuming loop configuration to a horizontal movement mechanism, effectively reducing the space occupied in the tower while maintaining the same protective function
2Reliability
If a cable loop arrangement is used, then cable torsion is compensated, but device complexity and installation time increase
Solution Approach 1:
The horizontal movement element provides dynamic torsion compensation through controlled horizontal movement, replacing the complex static loop geometry. This simplifies the overall device structure while maintaining the essential function of torsion compensation, reducing both device complexity and installation requirements
Solution Approach 2:
The patent extracts the essential function of torsion compensation from the complex cable loop arrangement and implements it through a simplified horizontal movement mechanism. By separating the compensation function from the bulky loop structure, the invention reduces device complexity while preserving the core protective function
3Ease of operation
If traditional cable guiding structures are used, then cables are guided from nacelle to tower base, but cable abrasion increases due to fixed positioning
Solution Approach 1:
The horizontal movement element enables dynamic cable positioning that adapts to cable movement and tension changes. This dynamic adjustment prevents fixed-point abrasion by allowing the cable guiding structure to move with the cable, thereby reducing wear while maintaining effective cable guidance throughout the tower
