Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If sensing tasks are performed to acquire environmental information, then sensing capability is improved, but privacy leakage of non-target electronic devices occurs
Solution Approach 1:
The patent segments the sensing process by separating target devices from non-target devices through identifier analysis. The network device divides the sensing area into target regions and non-target regions, applying different processing rules to each segment. This allows the system to maintain sensing capability for target devices while protecting privacy of non-target devices by excluding them from sensing results.
Solution Approach 2:
The network device acts as an intermediary between the sensing system and electronic devices. It receives sensing tasks, analyzes device identifiers to determine which devices are targets versus non-targets, and filters results accordingly. This intermediary role enables the system to perform sensing while preventing privacy leakage by controlling what information is returned to the sensing application.
2Measurement precision
If all electronic devices within sensing range are identified, then sensing accuracy is improved, but privacy protection complexity increases
Solution Approach 1:
The patent applies preliminary action by having the network device pre-analyze device identifiers and determine target versus non-target status before executing the sensing task. Device information is pre-processed and categorized, so that during the actual sensing operation, the system only processes relevant target devices. This preliminary classification simplifies the overall process while maintaining accuracy.
Solution Approach 2:
The patent extracts only the necessary device identifier information from the complete device data set. Instead of processing all device information, the system extracts and analyzes only the identifier portion to determine target status. This extraction approach maintains sensing accuracy by identifying correct targets while reducing privacy protection complexity by minimizing the amount of sensitive data that needs to be handled.
