Solution Overview
Problem
IoT devices face challenges in efficiently managing power resources while maintaining data transmission capabilities, as power consumption varies with data capture and communication protocols, leading to potential depletion of battery power.
Innovation Solution
A central IoT controller monitors power reserves and adjusts configuration settings, such as communication protocols and sensor operations, to conserve power by leveraging trusted devices or other IoT devices for data capture and communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If IoT devices use high-power communication protocols like LTE for data transmission, then data transmission capability is improved, but power consumption increases
Solution Approach 1:
The system dynamically switches between different communication protocols (LTE, Wi-Fi, Bluetooth) based on real-time conditions such as power availability, data urgency, and network conditions. This dynamic adaptation allows the device to use high-power protocols only when necessary while defaulting to low-power alternatives, resolving the contradiction between transmission capability and power consumption
Solution Approach 2:
The system changes operational parameters by adjusting communication protocol selection, transmission power levels, and data sampling rates based on power reserve status. When power is abundant, higher-power protocols are used; when power is limited, the system transitions to lower-power protocols and reduces transmission frequency, thereby balancing performance with energy constraints
2Quantity of substance
If IoT devices capture and transmit more data, then data capture capability is improved, but power resources are depleted faster
Solution Approach 1:
The system implements partial data capture and transmission by selectively monitoring and transmitting only critical or changed state data rather than continuously capturing all sensor data. This partial action approach maintains essential data capture capability while significantly reducing power consumption to extend operational life
Solution Approach 2:
The system uses feedback mechanisms where the controller monitors power reserve levels and adjusts data capture and transmission rates accordingly. When power reserves are low, the system reduces data capture frequency and prioritizes transmission of only essential data, creating a feedback loop that balances data capability with operational duration
3Productivity
If IoT devices operate independently without data sharing, then device autonomy is maintained, but operational efficiency decreases
Solution Approach 1:
The system merges data capture and processing functions across multiple IoT devices by enabling them to share sensor data and computational tasks. When devices are in proximity, they can offload data processing to nearby devices or combine their sensor readings, improving overall operational efficiency while the centralized controller manages the coordination to handle complexity

AI summary
A central IoT controller is described for conserving power resources of mobile IoT devices. Specifically, the central IoT controller is configured to at least monitor power reserves of mobile IoT devices, and in response to detecting that a power reserve has fallen below a predetermined threshold, generate computer-executable instructions that adjust configuration settings of the mobile IoT devices to conserve a remaining power reserve. The central IoT controller may modify a check-in interval for mobile IoT devices, configure the transmission of data communications via more power-efficient communication protocols, or reduce the number of active sensors on the mobile IoT device based on proximity to a trusted geolocation or a trusted device. Further, data communications may be rerouted via a proximate trusted device or other proximate mobile IoT device, in response to such device providing an efficiency with respect to available communication protocols.
