Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If terminals are directly mounted on the magnetic core, then device complexity is reduced, but insulation performance between terminals and core deteriorates
Solution Approach 1:
The patent introduces an insulation frame as an intermediary component between the magnetic core and the terminal. This insulation frame, made of insulating material, mediates the connection by providing both mechanical support and electrical insulation, thus resolving the contradiction between simplified structure and adequate insulation performance.
2Reliability
If insulation distance between terminal and core is increased, then insulation performance is improved, but device volume increases
Solution Approach 1:
The patent merges multiple functions into the insulation frame: it provides electrical insulation between the terminal and magnetic core, maintains the required insulation distance, and serves as a mounting structure for the terminal. This integration achieves adequate insulation performance without proportionally increasing device volume.
3Reliability
If insulation frame is introduced to house magnetic core, then insulation performance between terminal and core is improved, but device complexity increases
Solution Approach 1:
The insulation frame is designed as a multi-functional component that simultaneously provides electrical insulation, mechanical support for the magnetic core, mounting structure for terminals, and structural framework for the entire device. This universality reduces the need for separate components, thereby limiting the increase in overall device complexity.
