PoE Battery Hub Charging for Low-Duty Networked Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing window shade systems face challenges in efficiently utilizing power-over-ethernet (POE) networks to power both continuous and low duty cycle devices, as the available power is often insufficient for multiple motors due to varying load requirements, leading to reduced motor lifecycle and increased labor for battery replacement or recharging.
Innovation Solution
A system comprising a POE network switch, intelligent power distribution hub (IPDHG), and rechargeable batteries that manage power distribution and charging, optimizing power usage by charging low duty cycle devices during off-peak times and using batteries to supplement power delivery, allowing for more devices per port and reducing the need for frequent battery replacements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If POE is used to power multiple motors on a single port, then the number of devices per port increases, but the available power becomes insufficient due to varying load requirements
Solution Approach 1:
The system performs preliminary charging of batteries during off-peak times when power demand is low. The POE network switch charges batteries in advance so that when devices need power, the batteries are already charged and can supply the required power without exceeding the POE port's power capacity.
Solution Approach 2:
Batteries serve as an intermediary energy storage medium between the POE power source and the motors. The batteries receive power from the POE network during charging periods and then supply power to the motors during operation, decoupling the instantaneous power demand from the available POE power capacity.
2Adaptability or versatility
If batteries are used to power low duty cycle devices, then the devices can operate independently of continuous power supply, but the battery lifecycle is reduced to match the motor lifecycle
Solution Approach 1:
The system performs preliminary charging of batteries during off-peak times when power demand is low. The POE network switch charges batteries in advance so that when devices need power, the batteries are already charged and can supply the required power without exceeding the POE port's power capacity.
Solution Approach 2:
The system automatically manages battery charging and power distribution without requiring manual intervention. The POE network switch and IPDHG intelligently control when devices are charged and when power is delivered, optimizing battery usage and extending their operational lifespan.
3Reliability
If batteries are recharged frequently to maintain operation, then continuous operation is maintained, but labor for battery replacement or recharging increases
Solution Approach 1:
The system performs preliminary charging of batteries during off-peak times when power demand is low. The POE network switch charges batteries in advance so that when devices need power, the batteries are already charged and can supply the required power without exceeding the POE port's power capacity.
Solution Approach 2:
The system automatically manages battery charging and power distribution without requiring manual intervention. The POE network switch and IPDHG intelligently control when devices are charged and when power is delivered, optimizing battery usage and extending their operational lifespan.
4Power
If peak power is delivered to low duty cycle devices, then the devices can operate at full capacity during use, but the average power requirements remain low creating waste
Solution Approach 1:
The system performs preliminary charging of batteries during off-peak times when power demand is low. The POE network switch charges batteries in advance so that when devices need power, the batteries are already charged and can supply the required power without exceeding the POE port's power capacity.
Solution Approach 2:
The system maintains continuous operation by storing energy in batteries during low-demand periods and releasing it during high-demand periods. This ensures that devices can operate continuously without interruption while the power source only needs to provide power during off-peak times, optimizing energy utilization.
