Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If battery-free and low-cost IoT devices are deployed to enrich terminal types and quantity, then the Internet of Everything can be truly implemented, but power consumption management and information exposure control become critical problems
Solution Approach 1:
The patent introduces an AF entity as an intermediary between IoT devices and the network. This intermediary manages information exposure and device operations on behalf of battery-free IoT devices, reducing their operational burden and power consumption while enabling versatile deployment across different terminal types.
2Ease of operation
If information exposure services are implemented for IoT device management, then on-demand management capability is improved, but network complexity and information security requirements increase
Solution Approach 1:
The AF entity serves as a mediator that simplifies device management operations for users while handling the complexity of information exposure control within the network. This allows easy on-demand management of IoT devices without directly increasing network complexity, as the AF entity absorbs the management overhead.
Solution Approach 2:
The patent implements selective information exposure where different levels of device information are exposed to different AF entities based on specific needs. This local quality approach allows precise control over information exposure, enabling easy management operations while maintaining security and minimizing unnecessary network complexity.
