Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Portable computing devices (PCDs) face limitations due to their small form factor, which restricts the number of ports and connections, hindering access to power and capabilities despite increasing computing power.
Innovation Solution
A method and system for managing power distribution between a PCD and a docking station, involving switching power supplies, monitoring battery conditions, and transmitting warnings, to optimize power usage and charging when docked or undocked.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the PCD form factor is reduced to improve portability, then ease of carrying is improved, but the number of ports and connections is reduced
Solution Approach 1:
The system divides the connection capabilities into two segments: the portable PCD unit and the docking station. The PCD handles portability while the docking station provides the expanded interface capabilities, allowing the small device to access multiple ports through the dock.
Solution Approach 2:
The docking station acts as an intermediary between the PCD and external devices. It provides the expanded port capabilities that the small PCD cannot accommodate directly, mediating all connections and power distribution between the PCD and external peripherals.
2Duration of action of moving object
If the PCD battery capacity is increased to extend operation time, then duration of action is improved, but weight and volume increase
Solution Approach 1:
The excess battery capacity is extracted from the PCD and placed in the docking station instead. This allows the PCD to remain lightweight while the dock provides extended power reserves for scenarios where the PCD is docked for prolonged periods.
Solution Approach 2:
The docking station battery serves multiple functions: it charges the PCD battery when docked, provides power to external peripherals, and can operate independently to extend the overall system's operational duration beyond what the PCD battery alone could provide.
3Productivity
If power is continuously supplied to the PCD while docked, then productivity is improved, but energy consumption increases
Solution Approach 1:
The power management system dynamically adjusts power distribution based on the PCD's operational state. When the PCD is docked and receiving power, the system monitors energy levels and automatically manages charging cycles, switching between the PCD battery and docking station battery as needed.
Solution Approach 2:
The system implements feedback mechanisms that monitor battery charge levels, power consumption rates, and operational demands. This feedback enables intelligent control of power flow, ensuring continuous operation when needed while minimizing energy waste through optimized charging and power distribution.

AI summary
A method of managing power distribution between a portable computing device (PCD) and a PCD docking station is disclosed and may include determining that the PCD is docked with the PCD docking station, switching a power supply to the PCD from a PCD battery to a PCD docking station battery, and powering the PCD and the PCD docking station from the PCD docking station battery. Further, the method may include determining whether a PCD battery power equals a charge condition and charging the PCD battery when the PCD battery power equals the charge condition. The method may also include monitoring a PCD docking station battery power, determining whether the PCD docking station battery power equals a warning condition, and transmitting a first warning when the PCD docking station battery power equals the warning condition.
