Communication Device with Buffered Transmission for Outdoor Gateways
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge of providing power to communication gateways installed outdoors, where commercial power is unavailable, leads to increased size and mass of battery units due to high power consumption, and limits output power and operation time.
Innovation Solution
A communication device with a first wireless communication means for intermittent reception and a second wireless communication means for controlled transmission, utilizing a communication control means to temporarily hold data and power off the second means until a predetermined condition is satisfied, then power it on for data transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a battery unit is mounted on the gateway to secure electrical power, then the gateway can operate outdoors without commercial power, but the size and mass of the battery unit increase due to high power consumption
Solution Approach 1:
The gateway performs wireless communication in periodic intervals rather than continuously. The communication unit is powered on only when data transmission is required and powered off otherwise, reducing total power consumption and allowing for a smaller battery unit while maintaining outdoor operation capability.
2Adaptability or versatility
If a battery unit is mounted on the gateway to secure electrical power, then the gateway can operate outdoors without commercial power, but the operation time is limited due to high power consumption
Solution Approach 1:
The gateway performs wireless communication in periodic intervals rather than continuously. The communication unit is powered on only when data transmission is required and powered off otherwise, reducing total power consumption and extending the operation time of the battery unit while maintaining outdoor operation capability.
3Productivity
If the second wireless communication means is powered on continuously, then data transmission can be performed immediately, but power consumption increases
Solution Approach 1:
The second wireless communication means is powered on periodically only when data needs to be transmitted, not continuously. This reduces power consumption while maintaining the capability to transmit data promptly when required, balancing responsiveness with energy efficiency.
Solution Approach 2:
The communication control unit holds received data in a buffer before transmission. When the second wireless communication means is powered on, data is transmitted immediately from the buffer, ensuring responsive data transmission without requiring continuous power supply to the communication unit.
