Solution Overview
Problem
Portable electronic devices face rapid power consumption issues due to frequent use, and portable power banks often require additional transmission wires and cannot prioritize power distribution between devices and accessories.
Innovation Solution
A method and system where a portable electronic device controls a portable power bank to selectively provide power to an electrical appliance based on available energy, using a communication interface, power outputting module, switching unit, and control unit to manage power modes and eliminate the need for separate chargers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If a portable power bank is used to extend service time, then battery life is extended, but additional transmission wires and separate chargers are required
Solution Approach 1:
The patent merges the power bank functionality with the portable electronic device by integrating the power outputting module, switching unit, and control unit into a single integrated system. The power bank can charge both the electronic device and electrical appliances through integrated power management, eliminating the need for separate chargers and reducing cable requirements.
Solution Approach 2:
The power bank is designed with multi-functionality to charge different types of devices simultaneously. It can provide power to the portable electronic device, electrical appliances, or both at the same time through intelligent power allocation, making a single device replace multiple separate charging solutions.
2Duration of action of moving object
If power is provided to both portable electronic device and electrical appliance, then service time is extended, but power consumption increases rapidly
Solution Approach 1:
The patent implements dynamic power management through a control unit that continuously monitors power levels and adjusts power distribution in real-time. The switching unit dynamically allocates power between the portable electronic device and electrical appliances based on current needs and available power, optimizing energy utilization and extending service time without excessive power consumption.
Solution Approach 2:
The control unit receives feedback regarding power levels and usage status from both the electronic device and electrical appliances. Based on this feedback, the system intelligently adjusts power allocation to ensure efficient energy usage, preventing overconsumption while maintaining extended service time for both devices.
3Reliability
If mobile device has higher priority over portable electrical accessories, then power is ensured for mobile device, but power distribution cannot be selectively managed
Solution Approach 1:
The patent implements dynamic priority management where the power allocation between the mobile device and electrical appliances can be adjusted in real-time. The control unit monitors power levels and can dynamically change which device receives priority power supply, allowing selective management while ensuring the mobile device maintains reliable power access when needed.
Solution Approach 2:
The system changes power distribution parameters dynamically based on usage conditions. The control unit can adjust power allocation ratios, switching between different power distribution modes to balance reliability for the mobile device with adaptability for selective power management to electrical appliances.

AI summary
A method of power management is to be implemented by a portable electronic device coupled to a portable power bank. The portable power bank is further coupled to an electrical appliance. In the method, the portable electronic device receives power information from the portable power bank, and controls the portable power bank to operate in one of a first mode, in which electrical power is provided to the electrical appliance, and a second mode, in which electrical power is not provided to the electrical appliance, based on whether or not the portable power bank has sufficient amount of power.
