Engineering Contradiction Analysis
1Quantity of substance
If USB charging is used to connect portable electronic devices with personal computer, then charging operation can be performed, but amounts of additional charging currents are limited due to operation of the personal computer
Solution Approach 1:
The patent implements dynamic current adjustment by detecting the operating state of the personal computer and dynamically changing the charging current amount. The control module adjusts charging parameters in real-time based on detected computer operation states, allowing the system to transition from static USB current limitations to dynamic current optimization, thereby utilizing larger charging currents when the computer is under light load while maintaining stability when the computer requires more power.
2Productivity
If users utilize charging currents being larger than the limitations of the additional charging currents, then charging speed increases, but the personal computer may fail to maintain the minimum operational current
Solution Approach 1:
The patent employs feedback mechanisms where the detection module continuously monitors the personal computer's operational current and operating state. Based on this feedback, the control module adjusts the charging current to ensure the computer maintains minimum operational current requirements. When the computer's power consumption increases, the system automatically reduces or stops additional charging current to prevent shutdown, thereby maintaining system reliability while optimizing charging speed under appropriate conditions.
3Power
If converter is used to access DC/AC power supplies, then charging capability is improved, but convenience deteriorates due to need to carry converter
Solution Approach 1:
The patent enables the personal computer to serve multiple functions: it acts as both a data processing device and a power supply device for charging portable electronic devices. By utilizing the computer's existing power capacity and USB interface, the system eliminates the need for separate converters or external power adapters, thereby improving portability and convenience while maintaining adequate charging capability for standard applications.
4Reliability
If predetermined limitations of additional charging currents are maintained, then computer operation is stable, but extra charging currents cannot be utilized
Solution Approach 1:
The patent transforms the static, predetermined current limitations into dynamic, adaptive current allocation. The control module continuously detects the computer's operational state and adjusts the charging current accordingly, allowing the system to utilize larger charging currents when the computer is under light load while maintaining stability when the computer requires more power. This dynamic approach maximizes the available charging current throughout the charging process.
