Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Information handling systems face challenges in efficiently selecting and switching between power sources, such as wired and wireless power, to optimize power delivery to system modules, ensuring continuous operation without power disruptions or inefficiencies.
Innovation Solution
The system employs a wireless power module, a wired power connector, and an embedded controller to determine available power sources, selecting the most efficient option and switching between them, including battery power, to ensure reliable and efficient power supply to information handling system electronics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the system switches between multiple power sources (wired, wireless, battery), then power delivery efficiency is optimized, but system complexity increases
Solution Approach 1:
An embedded controller acts as an intermediary to manage power source selection and switching. The controller receives power availability information from multiple sources (wired power connector, wireless power module, battery), determines the most efficient power source, and controls switching between them. This centralized mediation simplifies the overall system architecture while enabling efficient multi-source power management.
2Reliability
If the system continuously monitors power sources, then power disruptions are reduced, but energy consumption increases
Solution Approach 1:
The embedded controller periodically monitors power availability from different sources rather than continuously tracking all parameters. The system checks power source status at defined intervals, determining when switching between wired, wireless, and battery power is necessary. This periodic monitoring maintains reliable power supply while reducing unnecessary energy consumption associated with continuous real-time monitoring.
Data Source
AI summary
An information handling system can receive power from a wireless or wired power source. In response to determining the information handling system is coupled to the wired power source, the system decouples the wireless power source from providing power. In response to the system being decoupled from the wired power source, the information handling system couples the wireless power source to the system.
