Solution Overview
Problem
Modular electrical devices that need to perform multiple functions, such as circuit breaker and differential protection, become bulky due to the high number of components required, leading to size and complexity issues.
Innovation Solution
Incorporating the annular magnetic circuit of an electric transformer into the connection part of the device, allowing for the inclusion of other bulky components without the need for excessive miniaturization, which simplifies the design and reduces complexity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple functional components are arranged inside the device to perform simultaneous functions (circuit breaker and differential protection), then the device can perform multiple functions, but the device becomes bulky and increases in width
Solution Approach 1:
The patent merges the transformer's magnetic circuit with the connection parts by making the first connection part form the first pole of the magnetic circuit and the second connection part form the second pole. This integration allows the transformer to be embedded within the connection structure rather than occupying separate space, enabling multiple functions (differential protection via transformer and circuit breaker via magnetic trip) while maintaining a compact 2-module width.
2Area of stationary object
If the device width is reduced to minimize size, then the device becomes more compact, but the components must be excessively miniaturized which reduces their performance and increases assembly complexity
Solution Approach 1:
By combining the connection parts with the magnetic circuit poles, the patent eliminates the need for separate transformer components that would require miniaturization. The connection terminals and magnetic circuit share the same structural elements, allowing standard-sized components to be used while maintaining compact dimensions, thus reducing assembly complexity.
3Ease of manufacture
If the connection part is occupied exclusively by terminals, then the terminal arrangement is simplified, but space is wasted that could be used for other bulky components
Solution Approach 1:
The connection parts serve dual functions: they provide electrical connection terminals and simultaneously form the poles of the transformer's magnetic circuit. This multi-functionality allows the same structural elements to fulfill both connection and magnetic circuit requirements, optimizing space utilization without complicating the terminal arrangement.
