Rotating Electrical Machine Connector Replacement Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional drive-device-integrated rotating electrical machines have an integral housing and connector section, making it impossible to replace only the connector section and limiting the flexibility in connector arrangement.
Innovation Solution
The design allows for the sole replacement of the connector section and enhances flexibility by attaching it to different portions of the housing, enabling easy attachment and detachment while maintaining the use of a common drive device, and allows for varying the direction of power and signal terminals to adjust the connector arrangement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the housing section and connector section are configured integrally, then the structural strength and rigidity are improved, but the replaceability of the connector section deteriorates
Solution Approach 1:
The patent divides the drive device into two separate sections: a housing section and a connector section. The connector section is designed as an independent detachable unit that can be separated from the housing section. This segmentation allows the connector to be replaced independently without replacing the entire housing, thus improving ease of repair while maintaining structural integrity through proper connection interfaces.
2Ease of manufacture
If the housing section and connector section are configured integrally, then the manufacturing process is simplified, but the flexibility in connector arrangement deteriorates
Solution Approach 1:
By separating the connector section from the housing section, the patent enables flexible arrangement of connectors in various positions and orientations. The connector section can be independently designed and positioned according to specific application requirements, providing adaptability while maintaining relatively simple manufacturing processes for each separate component.
3Ease of repair
If the connector section is made detachable, then the ease of replacement is improved, but the device complexity increases
Solution Approach 1:
The patent implements a detachable connector section through clear segmentation between the housing and connector. This is achieved by providing a housing-side opening portion and corresponding connector-side structures that enable straightforward attachment and detachment. The segmentation approach maintains relatively simple device complexity by using direct connection interfaces without complex mechanisms.
