Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If information exposure management is implemented for IoT devices, then device connectivity and functionality are enhanced, but system complexity and power consumption increase
Solution Approach 1:
The patent introduces a Network Exposure Function (NEF) as an intermediary between application functions and IoT devices. The NEF manages information exposure requests by translating application function requirements into appropriate device information retrieval operations, thereby reducing system complexity while enabling enhanced connectivity and adaptability for IoT devices
2Use of energy by moving object
If battery-free and low-cost IoT devices are deployed, then device cost and power consumption are reduced, but information management and control capabilities are limited
Solution Approach 1:
The patent enables battery-free IoT devices to operate autonomously by having them self-register with the network and self-manage their information exposure requirements. The devices transmit their information requirements to the NEF without requiring complex local processing or battery-powered communication modules, thus maintaining low power consumption while enabling effective information management
Solution Approach 2:
The NEF acts as a mediator that receives information exposure requests from application functions, translates them into device-specific operations, and manages the IoT devices centrally. This allows simplified low-cost devices to be effectively managed without requiring complex local intelligence in each device
