Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple sensing access points are used to scan the area, then measurement precision and resolution are improved, but device complexity and resource coordination difficulty increase
Solution Approach 1:
A managing entity is introduced as an intermediary to coordinate multiple sensing access points. The managing entity receives requests from sensing access points, determines appropriate scan configurations, and provides responses with configuration information for probing signals. This intermediary structure enables multiple access points to work together for improved sensing precision while centralizing the complexity of resource coordination and configuration management.
2Productivity
If configuration information is shared among sensing access points, then resource utilization efficiency is improved, but information management complexity increases
Solution Approach 1:
Configuration information for probing signals is merged and centralized in the managing entity. The managing entity receives requests from multiple sensing access points, determines scan configurations, and provides unified configuration information that can be applied across multiple access points. This merging approach improves resource utilization efficiency by avoiding redundant configurations while the managing entity handles the complexity of information management centrally.
3Area of stationary object
If distributed sensing operations are implemented, then coverage area and sensing capability are improved, but scheduling difficulty and time coordination increase
Solution Approach 1:
The managing entity performs preliminary actions by determining scan configurations and providing configuration information to sensing access points before actual sensing operations begin. Configuration information includes parameters such as probe signal resources, timing, and frequency settings. This preliminary configuration enables distributed access points to conduct sensing operations simultaneously or in a coordinated manner, expanding coverage area while minimizing scheduling delays during actual sensing.
