Wind Turbine Busbar Housing Thread Repair
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for repairing busbar housing sections in wind turbines often result in discarded components due to assembly errors or damaged threads, leading to unnecessary replacement and increased costs, as the faulty sections cannot be reused.
Innovation Solution
The method involves enlarging the damaged thread area, installing a support element with a replacement thread, and using an adhesive layer to secure the carrier element, allowing the screw to be reinserted and mechanically fixed, thus enabling the reuse of the original busbar housing section.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a busbar housing section with damaged thread is discarded and replaced with a new section, then the reliability of the connection is maintained, but the cost increases and assembly delays occur due to the need for spare parts
Solution Approach 1:
Instead of discarding the busbar housing section with damaged thread, the invention recovers it by installing a support element that provides a replacement thread. The original housing section is retained and reused after thread replacement, eliminating the need to discard functional components and reducing spare part requirements.
Solution Approach 2:
A support element is introduced as an intermediary component between the busbar housing section and the connecting element. This support element carries the replacement thread and enables the screw to be reinstalled, serving as a mediator that restores the connection functionality without requiring replacement of the entire housing section.
2Manufacturing precision
If a busbar housing section with damaged thread is replaced with a new section, then the manufacturing quality is maintained, but the cost increases due to investment in spare parts
Solution Approach 1:
The invention recovers the busbar housing section by replacing only the threaded function through a support element, rather than discarding the entire section. This selective recovery approach maintains manufacturing quality while avoiding the material cost of replacing the complete housing section.
Solution Approach 2:
The connection system is segmented into distinct functional components: the busbar housing section, the support element with replacement thread, and the connecting element. This segmentation allows the damaged thread function to be replaced independently while retaining the valuable housing section, reducing overall material cost.
3Loss of substance
If the original busbar housing section is reused after thread replacement, then cost is reduced, but the complexity of the repair process increases
Solution Approach 1:
The support element serves as a standardized intermediary component that simplifies the repair process. By providing a pre-fabricated replacement thread mechanism, it converts a complex thread repair operation into a straightforward installation process, reducing overall repair complexity despite reusing the original housing section.
4Reliability
If a support element with replacement thread is installed, then the original busbar housing section can be reused, but the device complexity increases due to the additional component
Solution Approach 1:
The support element is a compact intermediary component that consolidates multiple functions (replacement thread, mounting interface) into a single element. This minimizes the increase in device complexity while ensuring reliable connection through the replacement thread mechanism.
