Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple standalone power banks and UPS systems are deployed to support multiple devices, then device power coverage is improved, but system complexity and cost increase
Solution Approach 1:
The patent combines multiple standalone power banks and UPS systems into a single integrated power management system that can simultaneously charge multiple devices with different power requirements. The system integrates AC/DC power conversion, multiple charging ports, and centralized control into one unit, eliminating the need for multiple separate devices while maintaining comprehensive device coverage.
Solution Approach 2:
The power management system is designed with universal functionality to support various device types including smartphones, tablets, laptops, and other electronic devices. It provides multiple output ports with different voltage and current capabilities, allowing a single system to serve multiple purposes and device categories that previously required separate power solutions.
2Ease of operation
If all connected devices are powered continuously, then device availability is improved, but energy consumption increases
Solution Approach 1:
The system dynamically adjusts power distribution to connected devices based on their actual charging needs and device availability status. The intelligent power management controller monitors each device's charging state and automatically allocates or stops power supply accordingly, ensuring devices remain available when needed while minimizing energy consumption during idle periods.
Solution Approach 2:
The power management system incorporates feedback mechanisms that continuously monitor the charging status, power consumption, and availability of connected devices. This feedback information is used by the control algorithm to optimize power allocation in real-time, balancing device availability requirements with energy conservation goals.
3Quantity of substance
If high-capacity battery systems are used to provide extended power backup, then energy storage capacity is improved, but weight and portability deteriorate
Solution Approach 1:
The system optimizes the energy density parameters of the battery pack to achieve high storage capacity while minimizing weight. By selecting advanced battery chemistry and optimizing cell configuration, the system provides extended power backup capability without the excessive weight that would compromise portability and ease of deployment.

AI summary
A coordinated multiple power management system provides an efficient and unique means of controlling the power usage of devices attached to a personal energy platform. Power control in an abundant power situation (i.e. commercial power is available) saves money. Power control in a constrained power situation (i.e. commercial power is unavailable e.g. “power failure”) provides more availability of needed computing services (for example, emergency activities, enable longer communication periods, longer video streaming, security monitoring, internet access and communications, or critical healthcare device usage etc.). The power supplied to the devices can be determined automatically and is under program control, which allows the complete management and distribution of power to any, and all, devices attached to the personal energy platform.
