Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If wireless signal strength is used to determine proximity between devices, then wireless tagging service can be provided, but the service reliability deteriorates due to signal strength variations
Solution Approach 1:
The patent changes the parameter used for proximity determination from absolute signal strength to signal strength pattern recognition. By analyzing the temporal pattern of signal strength variations rather than relying on a single threshold value, the system achieves more reliable proximity detection despite signal fluctuations. This involves monitoring signal strength over multiple time points and comparing the resulting pattern against stored patterns for different devices.
2Ease of operation
If a single wireless signal threshold is used for proximity determination, then the system is simple to operate, but measurement precision deteriorates due to signal variations
Solution Approach 1:
The patent applies preliminary action by pre-storing signal strength patterns for multiple external devices before actual proximity determination is needed. During device pairing or initial setup, the system collects and stores the characteristic signal strength patterns of each device. When proximity determination is required later, the system simply compares the current signal pattern against these pre-stored patterns, maintaining ease of operation while achieving high measurement precision.
3Reliability
If customized wireless tag information is created for each external device, then service reliability improves, but device complexity increases
Solution Approach 1:
The patent uses copying by creating simplified representations (signal strength patterns) of each external device's wireless characteristics. Instead of implementing complex customization logic for each device, the system copies the essential signal strength pattern information during initial device interaction and stores it for future reference. This allows the system to provide customized, reliable service for each device while maintaining relatively simple operational complexity.
