Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If A-IoT devices use existing communication protocols, then communication can be established, but power consumption is high and charging time is long
Solution Approach 1:
The patent modifies communication protocol parameters specifically for A-IoT devices, adjusting transmission power levels, data rates, and timing parameters to optimize energy consumption while maintaining communication reliability. The system dynamically changes protocol parameters based on device energy status and communication requirements.
Solution Approach 2:
The communication protocol is made dynamic by allowing real-time adjustment of transmission parameters based on the A-IoT device's charging status and energy availability. The system transitions between different communication modes (e.g., low-power mode, high-data-rate mode) depending on current operational conditions.
2Loss of information
If A-IoT devices transmit data frequently, then data freshness is improved, but power consumption increases
Solution Approach 1:
The patent implements periodic transmission schedules where A-IoT devices transmit data at optimized intervals rather than continuously or on-demand. The transmission period is dynamically adjusted based on data importance, energy availability, and channel conditions, balancing data freshness with power consumption.
Solution Approach 2:
The system uses feedback mechanisms where the network receives information about the A-IoT device's energy status and adjusts transmission scheduling accordingly. The device also receives feedback about optimal transmission times and data prioritization to minimize energy usage while maintaining acceptable data freshness.
3Productivity
If reader device uses traditional communication initiation, then connection can be established, but charging time for A-IoT device increases
Solution Approach 1:
The patent implements preliminary actions where the reader device checks the A-IoT device's charging status before initiating full communication protocols. Energy-efficient pre-connection procedures are performed first, allowing the system to establish basic connectivity with minimal energy transfer, then proceed to full communication only when necessary and when energy is available.
Solution Approach 2:
The system uses partial communication initiation where only essential data is transmitted during initial connection, deferring non-critical data transfer to later when the device has accumulated sufficient energy. This partial action approach reduces the energy burden during connection establishment while maintaining productivity.
