Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing window shade systems face challenges in efficiently managing power distribution, particularly for low duty cycle devices, as they often rely on batteries with limited lifecycles and require manual recharging, leading to increased maintenance and reduced motor lifecycle.
Innovation Solution
A system utilizing a power-over-ethernet (POE) network switch and intelligent power distribution hub (IPDHG) that includes a rechargeable battery to manage power distribution, optimizing power usage by charging low duty cycle devices during off-peak times and supporting multiple devices per port, with a battery backup system for continuous use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If batteries are used to power low duty cycle devices, then the devices can operate during peak power demand, but the battery lifecycle is reduced and maintenance requirements increase
Solution Approach 1:
The system performs preliminary charging of batteries during off-peak hours when power demand is low, storing energy in advance for use during peak demand periods. This allows the batteries to be charged when the POE network switch has available capacity, extending the overall system lifecycle and reducing maintenance needs.
2Productivity
If multiple low duty cycle devices are connected to a single POE port, then device density is increased, but the available power per device is reduced
Solution Approach 1:
The system pre-charges batteries during off-peak hours when power demand is low, accumulating stored energy that can be drawn upon during peak demand. This allows multiple low duty cycle devices to be supported on a single POE port by distributing the power load over time rather than simultaneously.
Solution Approach 2:
The system maintains continuous operation of multiple devices by using battery storage to bridge power supply gaps. The POE network switch continuously charges batteries during available time windows, ensuring that devices remain operational throughout their duty cycles without interruption.
3Speed
If batteries are charged during peak power demand periods, then charging speed is increased, but the available power for device operation is reduced
Solution Approach 1:
The system performs charging operations during off-peak hours when power demand is low, accumulating battery charge in advance. This timing strategy allows fast charging during periods when the POE network switch has available capacity, without compromising the power available for device operation during peak demand periods.
