Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If integrated sensing and communication capabilities are added to communication systems, then sensing capability and adaptability are improved, but device complexity increases
Solution Approach 1:
The patent applies multi-functionality by enabling communication signals to serve dual purposes: both information transmission and environmental sensing. The sensing module processes communication signals to extract environmental parameters, allowing the same hardware infrastructure to perform multiple functions without requiring separate dedicated sensing equipment, thus improving adaptability while controlling complexity
Solution Approach 2:
The patent merges sensing and communication functions into an integrated system where the sensing module utilizes existing communication signal resources (reference signals, pilot signals) rather than requiring completely separate sensing hardware. This combination allows the system to achieve enhanced sensing capability while avoiding the complexity increase that would result from entirely independent sensing and communication subsystems
2Device complexity
If communication systems use existing communication signals for sensing, then device complexity is reduced, but measurement precision may be insufficient
Solution Approach 1:
The patent introduces a dedicated sensing module that acts as an intermediary between the communication signals and the environmental parameter extraction process. This module applies specialized signal processing techniques (correlation analysis, parameter estimation) to communication signals, enabling precise sensing measurements while reusing existing communication infrastructure, thus balancing precision requirements with complexity constraints
