Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If multiple independent input power sources are used to achieve rapid voltage regulation, then voltage regulation speed is improved, but device complexity and volume increase
Solution Approach 1:
The patent merges multiple voltage source functions into a single power source device that can output multiple different voltages. Instead of using multiple independent power sources, one power source is designed to provide multiple voltage levels (e.g., 5V, 3.3V, 1.8V) through internal switching and regulation mechanisms, thereby reducing device complexity while maintaining rapid voltage regulation capability.
Solution Approach 2:
The patent implements dynamic voltage regulation by enabling the power source to switch between different voltage output levels in real-time based on load requirements. The power source can dynamically adjust its output voltage from 5V down to 1.8V or other levels through controlled switching of internal circuits, achieving rapid response without requiring multiple static power sources.
2Speed
If multiple independent input power sources are used to achieve rapid voltage regulation, then voltage regulation speed is improved, but manufacturing cost increases
Solution Approach 1:
The patent combines the functions of multiple power sources into a single integrated device, reducing the total component count and assembly requirements. By manufacturing one multi-voltage power source instead of multiple separate units, production costs, assembly costs, and testing costs are all reduced while maintaining the capability to provide multiple voltage levels rapidly.
Solution Approach 2:
The patent designs a universal power source that can serve multiple voltage requirements simultaneously. This multi-functional device can output different voltages (5V, 3.3V, 1.8V, etc.) based on demand, replacing the need for multiple specialized power sources and thereby reducing overall manufacturing costs through economies of scale and simplified production processes.
3Volume of stationary object
If a single current source supplies power to multiple voltage sources, then device volume is reduced, but power distribution complexity increases
Solution Approach 1:
The patent uses dynamic switching mechanisms within the single power source to distribute power to different voltage output lines as needed. Internal switching circuits can rapidly connect or disconnect different voltage generation paths based on which voltage level is currently required, enabling efficient power distribution from a single source without requiring complex permanent connections to multiple voltage sources.
Solution Approach 2:
The patent introduces internal voltage regulation and switching circuits as intermediary components between the single current source and the multiple voltage outputs. These intermediary circuits manage the power distribution intelligently, converting the single input current into the required multiple voltage levels through controlled rectification, regulation, and switching, thereby simplifying the overall architecture while managing distribution complexity internally.
