Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing switching devices face challenges in facilitating simultaneous and efficient assembly and access to both the coil and main electrical conductors, while also ensuring proper insulation and reducing the complexity of assembly processes, particularly due to the use of split enclosures and unreliable connections between coil power conductors.
Innovation Solution
A switching device design with the coil and fixed core positioned above the main power conductors, incorporating auxiliary and command conductors, and eliminating the need for intermediate split enclosures, which allows for a single assembly direction and improved insulation between conductor chambers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If intermediate split enclosures are used to position main and auxiliary conductors, then assembly access is facilitated, but alignment complexity and assembly time increase
Solution Approach 1:
The patent merges the main conductor enclosure and auxiliary conductor enclosure into a single integrated enclosure structure. This eliminates the need for separate intermediate split enclosures, reducing alignment complexity while maintaining easy assembly access. The integrated enclosure allows all conductors to be positioned and connected in one assembly operation rather than requiring precise alignment between multiple separate enclosures.
2Ease of manufacture
If split enclosures are used for conductor positioning, then assembly is simplified, but robustness under mechanical stress deteriorates
Solution Approach 1:
The patent combines multiple separate enclosures into a single robust enclosure structure that can withstand mechanical stress such as short-circuit forces. The integrated design eliminates weak points associated with multiple joint interfaces, while still maintaining ease of assembly through the enclosure's accessible design.
3Reliability
If spring or pressure terminal connections are used between coil conductors, then electrical connection is achieved, but reliability decreases due to wear and oxidation
Solution Approach 1:
The patent extracts and eliminates the spring or pressure terminal connection system from the coil conductor pathway. By repositioning the coil conductors to be directly accessible through the enclosure, the invention removes the intermediate connection components that are prone to wear, oxidation, and dimensional variation, thereby improving both reliability and component lifespan.
4Ease of operation
If coil is positioned below main conductors, then assembly access is improved, but connection reliability between coil terminals deteriorates
Solution Approach 1:
The patent changes the spatial arrangement by repositioning the coil at the same level as the main conductors rather than below them. This dimensional repositioning allows coil terminals to be directly accessible through the enclosure without requiring vertical connection through intermediate components, thereby maintaining easy assembly access while improving terminal connection reliability.
