Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional mobile communication systems are used, then communication capability is provided, but IoT devices with ultra-low power consumption cannot be supported
Solution Approach 1:
The patent introduces a base station as an intermediary that performs scheduling operations on behalf of IoT devices. The base station schedules uplink and downlink communications, resource allocations, and data transmissions, allowing battery-less IoT devices to communicate without having their own power consumption for these functions. This mediator approach enables ultra-low power consumption devices to access the mobile communication system.
Solution Approach 2:
The base station is designed to perform multiple functions including scheduling for both conventional terminals and IoT devices, managing uplink and downlink communications, and handling resource allocation. This multi-functional capability allows the system to support diverse device types with different power consumption requirements through a unified scheduling mechanism.
2Ease of operation
If IoT devices perform autonomous communication, then communication flexibility is improved, but power consumption increases
Solution Approach 1:
The patent extracts the scheduling function from the IoT device and relocates it to the base station. By taking out the complex scheduling operations (uplink scheduling, downlink scheduling, resource allocation) from the IoT device, the system reduces the device's power consumption requirements while maintaining communication functionality through base station-controlled scheduling.
3Use of energy by moving object
If base station scheduling is implemented for IoT devices, then power consumption is reduced, but system complexity increases
Solution Approach 1:
The patent merges the scheduling functions for IoT devices with the existing base station scheduling infrastructure. By combining IoT device scheduling with conventional terminal scheduling in a unified base station scheduler, the system avoids duplicating scheduling mechanisms and reduces overall system complexity while achieving ultra-low power consumption for IoT devices.
