Single Power Adapter for Notebook and External Graphics Card
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current power control systems for notebook computers require two separate power adapters to supply power to external graphics renderers and the notebook itself, which is inconvenient and inefficient.
Innovation Solution
A power control system comprising a power supply device and an electronic device, where the power supply device includes a power supply, a voltage conversion chip, a power controller, and an electronic switch, allowing for the conversion and distribution of power voltages (5V, 12V, and 19V) to efficiently power both the graphics card and the notebook computer through a single connector, enabling communication and control protocols for optimized power management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If two separate power adapters are used to supply power to external graphics renderer and notebook computer, then each device receives adequate power, but the system complexity and ease of operation deteriorate due to requiring multiple adapters
Solution Approach 1:
The patent combines two separate power adapters into a single integrated power adapter that can simultaneously supply power to both the notebook computer and external graphics renderer. The power adapter includes a power supply unit, a first power controller for the notebook, and a second power controller for the graphics renderer, all integrated into one device. This merging eliminates the need for two separate adapters while maintaining adequate power supply to both devices.
Solution Approach 2:
The single power adapter is designed with multi-functionality to serve multiple purposes: it can supply power to the notebook computer through the first power controller, supply power to the external graphics renderer through the second power controller, and manage power distribution between both devices. The adapter includes voltage conversion chips and power controllers that enable it to handle different power requirements of different devices simultaneously.
2Reliability
If two separate power adapters are used, then each device has dedicated power control, but the device complexity increases due to multiple adapters and power controllers
Solution Approach 1:
The patent merges multiple power controllers into a single integrated power adapter. The adapter includes a power supply unit, a first power controller with first and second voltage conversion chips for the notebook, and a second power controller with third and fourth voltage conversion chips for the graphics renderer. This integration maintains dedicated power control for each device while reducing the overall number of separate power adapter units.
3Ease of operation
If a single power adapter supplies power to both notebook and external graphics renderer, then ease of operation improves, but power distribution control and voltage conversion complexity increases
Solution Approach 1:
The patent segments the voltage conversion and power control functions into distinct modules within the single power adapter. The first power controller contains first and second voltage conversion chips for converting voltages for the notebook computer. The second power controller contains third and fourth voltage conversion chips for converting voltages for the external graphics renderer. This segmentation organizes the complex voltage conversion circuitry into manageable, functionally-separated units while maintaining a single integrated adapter design.
