Universal Generator Rotor Support Device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Generator rotors of varying shapes and sizes require different support tools for removal or installation, leading to inefficiencies and increased costs due to the need for multiple tools and complex handling processes.
Innovation Solution
A universal support device with a variable contact point system, integrated with a gantry and removal skid, allowing the support device to accommodate rotors of different diameters by adjusting the position of contact points on segmented surfaces, enabling secure handling and traversal during servicing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple different support tools are used for rotors of different diameters, then each rotor can be properly supported, but the device complexity and number of tools required increases
Solution Approach 1:
The support device is designed with a universal cradle structure that can accommodate rotors of different diameters through adjustment mechanisms. The cradle includes adjustable arms and contact points that can be repositioned to match various rotor sizes, allowing a single device to perform multiple functions that previously required multiple specialized tools.
Solution Approach 2:
The support device incorporates dynamic adjustment capabilities where the cradle arms and support contact points can be moved and repositioned during operation. This allows the device to adapt its configuration to match different rotor diameters, transforming a static single-purpose tool into a dynamic multi-purpose tool.
2Adaptability or versatility
If multiple different support tools are used for rotors of different sizes, then proper support is achieved, but the time and resources required for tool selection and handling increases
Solution Approach 1:
By providing a single universal support device that can handle multiple rotor sizes through adjustment mechanisms, the system eliminates the time required to select from multiple specialized tools. The universal cradle with adjustable arms allows operators to quickly adapt the device to different rotor dimensions without tool changes.
Solution Approach 2:
The support device includes pre-configured adjustment mechanisms and standardized components that allow for quick adaptation to different rotor sizes. The cradle structure is designed with predetermined adjustment points and modular elements that can be rapidly reconfigured, reducing the time required for tool preparation and selection.
