Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing power supply systems for electronic devices are inefficient as they often apply a constant high voltage, which is wasteful since maximum load current is temporary and occurs under restrictive conditions, leading to suboptimal power consumption.
Innovation Solution
A power module that regulates input voltage levels by monitoring current flow, using a combination of first and second power modules and a voltage controller to adjust voltage based on current information, ensuring the electronic device consumes power with maximum efficiency according to the system load's requirements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a constant high voltage is applied to the electronic device, then the device can operate with maximum load current, but power consumption increases and efficiency decreases
Solution Approach 1:
The patent implements dynamic voltage regulation by switching between first and second power modules based on real-time current monitoring. The voltage level is adjusted dynamically according to the actual load current requirements, transitioning from static high voltage to adaptive voltage levels that match the operational needs of the electronic device.
Solution Approach 2:
The system changes the voltage parameter based on current conditions by selecting different power modules. When current is high, the first power module operates; when current is low, the second power module takes over. This parameter adaptation resolves the contradiction between maintaining reliability and improving energy efficiency.
2Power
If the first power module operates continuously, then sufficient power is available for maximum load current, but power waste occurs during low current operations
Solution Approach 1:
The power supply system is segmented into two distinct power modules: a first power module for high current operations and a second power module for low current operations. This segmentation allows the system to select the appropriate module based on actual load requirements, avoiding the energy waste that would occur if a single high-power module operated continuously.
Solution Approach 2:
Instead of always applying excessive power through the first power module, the system applies partial power through the second power module when full power is not needed. This partial action approach eliminates energy waste during low current operations while maintaining sufficient power availability when required.
3Adaptability or versatility
If voltage level is always high, then the electronic device can handle diverse operations and resolutions, but power efficiency decreases under restrictive conditions
Solution Approach 1:
The system dynamically adapts voltage levels to match the actual operational requirements of the electronic device. By monitoring current and switching between power modules, the system maintains versatility for diverse operations while avoiding energy waste during restrictive conditions when lower current is sufficient.
