Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for controlling remote devices require proximity to a WiFi router or cellular network for data flow and remote accessibility, limiting their range and efficiency, especially for devices operating off the grid on low voltage batteries or solar power.
Innovation Solution
A Radio Frequency Field Controller (RFFC) system that uses Bluetooth connectivity with a mobile device to control Down Range Controllers (DRCs) at ranges greater than 50 meters, featuring a R.I.F.T system with a microcontroller unit, power management, and communication processors to enable long-range, deterministic data transmission and control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If WiFi or cellular network connectivity is used for remote control, then data transmission capability is improved, but range is limited by proximity requirements to routers or cellular coverage areas
Solution Approach 1:
The patent introduces RF Bluetooth Low Energy (BLE) technology as an intermediary communication layer between the mobile device and the Down Range Controller. This intermediary enables direct wireless communication without requiring proximity to WiFi routers or cellular towers, extending the control range beyond traditional wireless networks while maintaining reliable data transmission capability.
2Loss of information
If continuous monitoring and control operations are performed, then real-time data availability is improved, but power consumption increases for battery-operated devices
Solution Approach 1:
The patent implements periodic wake-up cycles where the Down Range Controller enters low-power sleep mode between operational cycles. The controller periodically wakes to check for commands from the RF Bluetooth interface, process sensor data, and transmit updates only when necessary. This periodic operation maintains near-real-time functionality while dramatically reducing average power consumption for battery and solar-powered devices.
Solution Approach 2:
The system incorporates feedback mechanisms where the controller only activates full monitoring and transmission operations when triggered by specific conditions, such as receiving a command from the mobile device or detecting changes in sensor readings. This event-driven feedback approach ensures real-time data availability when needed while conserving energy during stable operational states.
