Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If integrated sensing service is added to wireless communication system, then sensing service functionality is improved, but system complexity increases
Solution Approach 1:
The system is segmented into distinct functional modules: sensing service management module for handling service requests and configurations, sensing node management module for managing sensing nodes, and sensing event notification module for processing notifications. This modular segmentation allows sensing services to be added without complicating the entire system, as each module handles specific tasks independently.
Solution Approach 2:
The network entity is designed with multi-functionality, serving both traditional communication functions and new sensing service functions through a unified architecture. The same network infrastructure supports both communication traffic and sensing information traffic, eliminating the need for separate dedicated sensing systems and reducing overall system complexity.
2Productivity
If sensing information traffic is increased, then sensing service capability is improved, but impact on communication service quality worsens
Solution Approach 1:
Traffic management is segmented into separate handling paths: communication traffic follows existing protocols while sensing information traffic is managed through dedicated sensing event notification mechanisms. This segmentation allows sensing services to operate without interfering with communication service quality, as each traffic type is processed independently according to its specific requirements.
Solution Approach 2:
Different quality of service (QoS) parameters are applied locally to different traffic types. Communication services receive guaranteed QoS parameters for reliability, while sensing services are allocated appropriate resources based on their specific needs. This local quality differentiation ensures that sensing information traffic does not degrade communication service quality, as each type receives tailored resource allocation and prioritization.
3Ease of operation
If sensing service management procedures are simplified, then ease of operation is improved, but service activation control worsens
Solution Approach 1:
Service activation control is performed in advance through pre-configured sensing service management procedures. The network entity pre-establishes sensing service configurations, node registrations, and event notification parameters before actual sensing operations begin. This preliminary action ensures that when sensing services are activated, the control mechanisms are already in place and functioning, maintaining both simplicity and automated control without requiring complex real-time decision-making.
