Buffered Power Control for Periodic Wireless Transceiver Operation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Aircraft galley equipment faces power constraints due to limited internal power budgets on connectivity interface boards, preventing wireless communication between devices as wireless transceivers require more power than available for radio calibration and data transmission.
Innovation Solution
A power buffering system that stores input power until a predetermined level is reached, allowing the wireless transceiver to function periodically by activating it with buffered power, enabling data transmission and reception.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If wireless transceivers are added to galley equipment for data communication, then communication capability is improved, but power consumption exceeds the available power budget
Solution Approach 1:
The system accumulates energy in a buffer before the wireless transceiver needs to operate. The power buffer stores energy from the power supply during periods when the transceiver is not active, so that sufficient energy is available when transmission is required, resolving the contradiction between limited power budget and high power demand
Solution Approach 2:
The wireless transceiver operates periodically rather than continuously. The system activates the transceiver only when data needs to be transmitted or received, and keeps it inactive otherwise. This periodic operation pattern, combined with energy buffering, allows the transceiver to function despite the limited power budget
2Adaptability or versatility
If power is buffered to enable periodic high-power operation, then device functionality is improved, but system complexity increases
Solution Approach 1:
A power buffer is introduced as an intermediary component between the power supply and the wireless transceiver. This buffer acts as a mediator that decouples the continuous power supply from the periodic high-power demand, simplifying the control logic while enabling the desired operation pattern
Solution Approach 2:
The system changes the temporal distribution of power consumption by buffering energy. Instead of consuming power continuously at a low rate or requiring continuous high power, the system accumulates energy over time and releases it in periodic bursts, changing the power delivery parameters to match the transceiver's operational requirements
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables periodic operation of wireless transceivers and other high-power devices by using stored power, allowing limited but essential data communication without additional resources or weight, suitable for aircraft and similar constrained systems.
Implementation Method 1
A power buffer is provided in the system. The power buffer buffers input power from the power supply until a predetermined level of buffered power is available in the power buffer.
Data Source
AI summary
A power control system in which power from a power supply is buffered until a predetermined level of buffered power is available at which time the system activates a device to function powered by the buffered power. Thus, by buffering the available power, a higher power requirement load can be operated periodically e.g. data can be transmitted to/from a wireless transceiver periodically.
