Stator Frame Housing Integration for Wave Power Generators
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wave power generators face challenges in reliability and cost due to complex maintenance and high component counts, particularly in the interaction between the water-tight housing and interior components, which complicates assembly and increases manufacturing costs.
Innovation Solution
A stator frame that serves as both part of the housing and mounting structure for stator packets, utilizing a cylindrical metal tube with axially distributed mounting profiles and guiding means, reducing the number of components and simplifying assembly while enhancing structural integrity and support.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a separate stator frame structure is used, then the stator can be securely mounted, but the number of components increases and assembly becomes more complex
Solution Approach 1:
The housing is designed to directly serve as the stator frame, with mounting profiles integrated into the housing wall. This merging of functions eliminates the need for a separate stator frame structure, reducing component count while maintaining secure stator mounting capability
Solution Approach 2:
The housing performs multiple functions: it provides water-tight enclosure, structural support, and stator mounting framework. The integrated design allows the same component (housing) to fulfill both protective and structural roles, simplifying the overall device architecture
2Manufacturing precision
If the complete stator is assembled first and then inserted into the housing, then proper alignment can be achieved, but the assembly process becomes more time-consuming and complex
Solution Approach 1:
The mounting profiles are pre-formed as integral parts of the housing structure during housing manufacturing. This preliminary preparation of mounting features eliminates the need for separate alignment and assembly operations, allowing stator packets to be directly mounted in the correct positions
Solution Approach 2:
The stator is divided into discrete stator packets that can be independently mounted onto the housing using the pre-formed mounting profiles. This segmentation allows for simplified, modular assembly without requiring complete stator assembly prior to housing integration
3Ease of manufacture
If multiple separate components are used for housing and stator frame, then each component can be optimized independently, but manufacturing costs increase
Solution Approach 1:
The housing and stator frame functions are merged into a single integrated structure. By eliminating the interface between separate housing and frame components, the design reduces manufacturing steps, material requirements, and assembly operations, leading to lower overall manufacturing costs
