Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If cellular network is used only for communication, then communication function is simple and reliable, but sensing capability is lost
Solution Approach 1:
The patent extends the cellular network's functionality from purely communication purposes to include sensing capabilities. The network infrastructure is designed to perform both communication and sensing tasks using the same radio resources, making the system multi-functional and adaptable to diverse applications such as gesture recognition, breathing monitoring, and environment imaging.
Solution Approach 2:
The patent introduces a sensing control mechanism within the core network that acts as an intermediary to manage sensing tasks. This mediator receives sensing requests, selects appropriate access-network devices or terminal devices to perform sensing operations, and coordinates the sensing process without requiring separate dedicated sensing infrastructure.
2Measurement precision
If sensing tasks are performed without proper selection and control, then sensing operations can be executed, but sensing accuracy and reliability deteriorate
Solution Approach 1:
The patent implements a feedback mechanism where the sensing control network element receives sensing requests, selects appropriate devices to perform sensing, executes the sensing tasks, and returns sensing results. This closed-loop control ensures that sensing operations are properly managed and that accurate results are obtained through coordinated selection and execution.
Solution Approach 2:
The patent performs preliminary actions by having the sensing control network element select and instruct the appropriate access-network devices or terminal devices before the actual sensing task execution. This preliminary selection and instruction phase ensures that the most suitable devices are chosen to perform the sensing operations, thereby improving measurement precision.
3Productivity
If radio electromagnetic wave signal is used for both communication and sensing, then resource utilization is improved, but signal interference and measurement precision may worsen
Solution Approach 1:
The patent segments the use of radio electromagnetic wave signals by separating communication functions and sensing functions into distinct operational modes or time slots. The same physical radio resources are divided and allocated to different purposes, allowing both communication and sensing to occur using the same infrastructure while minimizing mutual interference through resource segmentation.
