PUSB Port Power Selection via Dynamic Current Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current USB ports cap power at 100 VA, limiting peripheral devices that require higher power spikes, potentially leading to system overload and malfunction without adequate overcurrent protection.
Innovation Solution
Implementing a dynamic current protection system that adjusts power levels from 100 VA to 130 VA or higher, allowing for maximum power spikes and preventing system overload by using a hardware initialization system to manage power distribution through a PUSB port, including a current protection circuitry that monitors and throttles power as needed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If power is capped at 100 VA through PUSB port, then system overload is prevented, but peripheral devices requiring higher power spikes (110-130 VA) cannot operate at maximum performance
Solution Approach 1:
The patent implements dynamic power adjustment by transitioning from a static 100 VA cap to a dynamic system that can provide up to 130 VA based on actual device needs. The hardware initialization system (BIOS) dynamically selects power levels (100 VA, 110 VA, 120 VA, or 130 VA) and the system dynamically adjusts power during operation, switching between 100 VA normal operation and higher power spikes when needed, resolving the contradiction between preventing overload and enabling maximum performance.
Solution Approach 2:
The patent changes the power parameter from a fixed 100 VA limit to a variable parameter that can range from 100 VA to 130 VA. The BIOS configurable power level parameter allows selection among multiple power levels, and the system monitors and adjusts power delivery based on device requirements, enabling the parameter to adapt to different operational states and device needs.
2Productivity
If power is increased to 130 VA or higher for maximum power spikes, then peripheral devices can operate at full capacity, but system overload and malfunction risk increases
Solution Approach 1:
The patent implements feedback mechanisms where the system monitors power consumption and device status, then adjusts power delivery accordingly. The hardware initialization system configures appropriate power levels based on device identification, and the system continuously monitors for overload conditions, reducing power from 130 VA back to 100 VA when spikes subside, ensuring reliable operation while enabling maximum performance when needed.
Solution Approach 2:
The patent performs preliminary configuration through the BIOS hardware initialization system, which pre-configures appropriate power levels (100 VA, 110 VA, 120 VA, or 130 VA) before device operation begins. This preliminary setup ensures that the system is prepared to provide appropriate power levels without risking overload, as the configuration is established through controlled initialization procedures.
