Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional dynamoelectric machine support systems require costly, high-strength materials and complex assembly processes, including the use of vertical boring machines, which are time-consuming and expensive, and often result in material distortion issues during welding.
Innovation Solution
A support system for dynamoelectric machines that includes a mounting pad with slots, spring bars bolted to the pad, a collar welded or brazed to the pad, and a key bar affixed between the spring bars, allowing for the use of lower-strength materials and reducing the need for extensive machining and bolted connections, thereby simplifying assembly and reducing costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If traditional high-strength materials and complex assembly processes are used, then structural strength and reliability are improved, but manufacturing cost and complexity increase
Solution Approach 1:
The support system is divided into modular components: mounting pads with integrated slots, spring bars, collars, and key bars. This segmentation allows each component to be manufactured separately using standard processes and then assembled together, reducing overall assembly complexity while maintaining structural integrity through standardized connection interfaces
Solution Approach 2:
The mounting pad serves multiple functions: it provides structural support, includes integrated slots for spring bar attachment, and serves as a welding surface for the collar. This multi-functionality reduces the number of separate components needed, simplifying the overall assembly process while maintaining structural strength
2Strength
If traditional welding processes are used with high-strength materials, then joint strength is improved, but material distortion and manufacturing cost increase
Solution Approach 1:
The design changes the material parameters by using lower-strength, more weldable materials that are less prone to distortion during welding. The mounting pad and collar are designed with geometry and thickness parameters that accommodate standard welding processes without requiring specialized high-strength material welding techniques, thereby reducing manufacturing difficulty and cost
3Manufacturing precision
If extensive machining and bolted connections are used, then precision and structural integrity are improved, but manufacturing time and cost increase
Solution Approach 1:
The slots for spring bar attachment are pre-formed as integral features of the mounting pad during its initial manufacturing process, rather than requiring separate machining operations during assembly. This preliminary action ensures precise alignment is built into the component itself, eliminating time-consuming on-site machining while maintaining manufacturing precision
Solution Approach 2:
The design merges the mounting pad and slot features into a single integrated component. The mounting pad includes built-in slots that combine the functions of structural support and spring bar attachment, eliminating the need for separate machining operations and multiple bolted connections, thereby speeding up assembly while maintaining alignment precision
