Wind Tower Elevator Wirefix In-Situ Replacement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for stabilizing elevators in wind towers face challenges in replacing wirefix components without disturbing the guide wire tension, leading to complex and time-consuming service processes.
Innovation Solution
A wirefix system that allows for in-situ attachment and removal without de-tensioning the guide wire, featuring a channel that can be opened around a tensioned guide wire for easy coupling and decoupling, and designs such as coarse-pitch springs, foldable structures, and dual-piece configurations for secure attachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the wirefix is designed to be securely attached to the guide wire, then the stabilization reliability is improved, but the difficulty of replacement increases and service time increases
Solution Approach 1:
The wirefix is divided into two separable halves that can be independently manipulated. This segmentation allows the wirefix to be attached to and removed from the guide wire without requiring complete disassembly or de-tensioning, thus maintaining reliability while enabling easy replacement.
Solution Approach 2:
The wirefix incorporates a dynamic opening mechanism that allows the channel to transition between closed (secure attachment) and open (easy removal) states. This dynamic capability enables the wirefix to provide stable attachment during operation while allowing quick replacement when needed.
2Force
If the guide wire tension is maintained high, then the stabilizing force is improved, but the difficulty of wirefix installation and removal increases
Solution Approach 1:
The wirefix halves are pre-positioned on opposite sides of the guide wire before attachment. This preliminary positioning allows the channel to be opened, the guide wire to be inserted, and then the halves to be closed together, enabling installation without de-tensioning the guide wire.
Solution Approach 2:
The channel structure acts as an intermediary mechanism that facilitates the insertion and removal of the guide wire through controlled opening and closing of the wirefix halves, allowing tensioned guide wire manipulation without requiring complete release of tension.
3Stability of the object's composition
If the wirefix channel is designed to be tightly closed, then the guide wire containment is improved, but the ease of opening for installation and removal decreases
Solution Approach 1:
The channel is segmented into two halves that can be independently opened and closed. This segmentation provides mechanical advantage for opening the channel during installation while ensuring tight closure during operation, balancing containment stability with installation ease.

AI summary
A system for stabilizing the vertical motion of an object in a wind power generating tower comprises at least one static guide, and a guide component attached to the object, e.g., an elevator car, constrained to the proximity of the static guide. In addition, at least one further containment, e.g., a wirefix, coupled to the static guide is able to pass through the first containment as the object moves vertically in the tower. Moreover, the further containment is disposed to maintain the static guide in a fixed relationship to a mounting structure, and the further containment is disposed for in-situ attachment.
