Wind Turbine Drive Train Transport Frame Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wind turbine drive trains are difficult to transport due to their large size and weight, exceeding standard truck dimensions, necessitating special transport and complicating return transport after unloading.
Innovation Solution
A transport frame comprising two interconnected frame parts that can be rearranged from a usage state to a transport state, allowing for easier handling and fitting within standard container and truck dimensions by shortening the length while maintaining width, with features like folding segments and vibration-damping elements for stability and protection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the transport frame dimensions correspond to the drive train dimensions, then the drive train can be accommodated, but the frame cannot fit on a normal truck for standard transport
Solution Approach 1:
The transport frame is divided into two separable frame parts that can be connected in different configurations. In the usage state, the frame parts are arranged side by side to provide sufficient capacity for the drive train. In the transport state, the frame parts are arranged one above the other to reduce the overall length and fit standard truck dimensions.
Solution Approach 2:
The transport frame transitions from a two-dimensional side-by-side arrangement in the usage state to a three-dimensional stacked arrangement in the transport state. This dimensional change allows the frame to maintain adequate capacity while reducing the length dimension to fit standard transport vehicles.
2Ease of operation
If the transport frame is designed for standard truck dimensions, then it can be transported easily, but it cannot accommodate the large and heavy drive train
Solution Approach 1:
The transport frame is designed as a dynamic structure that can change its configuration between usage and transport states. The frame parts can be repositioned and reconnected to transform from a compact transport configuration to an expanded usage configuration, allowing the same structure to serve both purposes with appropriate load capacity in each state.
3Stability of the object's composition
If the transport frame is made as a single integrated structure, then it provides structural stability, but it cannot be reconfigured for different transport and usage states
Solution Approach 1:
The transport frame is segmented into multiple frame parts that can be connected and disconnected. Each frame part maintains its structural integrity and stability, while the connection between parts allows for reconfiguration between different states, combining both stability and adaptability.
4Volume of moving object
If special transport is used for the drive train, then the large dimensions can be accommodated, but the return transport also requires special transport increasing cost and complexity
Solution Approach 1:
The transport frame is designed as a universal structure that can accommodate the drive train for transport while also fitting within standard truck dimensions. This multi-functionality allows the same frame to be used for both outbound and return transport using standard logistics, eliminating the need for separate special transport arrangements.
