Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a two-story structure with parallel substrates is adopted to increase density, then the device complexity increases, but the electrical characteristics deteriorate due to parasitic components
Solution Approach 1:
The patent converts the harmful parasitic inductance of substrate connectors into useful inductor elements by strategically positioning and designing the connectors to function as inductors in the power supply circuit, thereby eliminating the need for separate inductor components and improving electrical characteristics
Solution Approach 2:
The substrate connectors serve dual functions: providing mechanical and electrical connection between substrates while simultaneously functioning as inductor elements in the power supply circuit, reducing overall device complexity and improving electrical performance
2Volume of moving object
If the power supply circuit is simply densified by adopting the two-story structure, then the volume decreases, but the electrical characteristics remain suboptimal
Solution Approach 1:
The patent converts the harmful parasitic inductance into useful inductor elements, achieving both compact size and excellent electrical characteristics by making the connectors serve dual purposes
Solution Approach 2:
The patent merges the connection function and inductor function into a single component (the substrate connector), eliminating the need for separate inductor elements and achieving compact integration with improved electrical characteristics
