Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If beacon devices use fixed channels for broadcasting, then device simplicity is maintained, but interference increases and discovery efficiency decreases
Solution Approach 1:
The patent implements dynamic channel selection where beacon devices and user equipments adaptively choose communication channels based on real-time signal strength measurements. Instead of fixed channel assignment, the system continuously monitors RSSI values and dynamically switches to optimal channels, transforming the static channel configuration into a dynamic adaptive process that resolves the contradiction between simplicity and efficiency.
Solution Approach 2:
The system changes the channel parameter based on measured signal conditions. By monitoring RSSI values and selecting channels with optimal signal strength, the patent modifies the communication parameter (channel selection) adaptively. This parameter change approach enables the system to maintain simplicity while improving discovery efficiency through data-driven channel optimization.
2Loss of information
If user equipment continuously receives beacon signals from multiple devices, then complete service information is obtained, but battery power consumption increases
Solution Approach 1:
The patent extracts and processes only the most relevant beacon signals by implementing a filtering mechanism based on signal strength thresholds. Instead of continuously receiving all beacon signals, the system extracts only those signals that meet the RSSI threshold criteria, thereby obtaining sufficient service information while significantly reducing power consumption associated with processing unnecessary signals.
Solution Approach 2:
The system performs partial reception by setting a threshold for beacon signal processing. Rather than receiving and processing all beacon signals excessively, the patent applies partial action by only processing signals that exceed the predetermined RSSI threshold, achieving a balance between information completeness and energy efficiency.
3Adaptability or versatility
If beacon devices operate on overlapping frequencies with other wireless devices, then channel availability is maintained, but interference increases and transmission reliability decreases
Solution Approach 1:
The patent implements a feedback mechanism where both beacon devices and user equipments measure RSSI values and use this feedback information to select optimal communication channels. The system continuously monitors signal conditions and adjusts channel selection based on the feedback, thereby maintaining channel availability while avoiding interfered frequencies to ensure reliable data transmission.
Solution Approach 2:
The system performs preliminary channel assessment by measuring signal strength before establishing communication. By preemptively evaluating the RSSI values of available channels and selecting the optimal one in advance, the patent ensures reliable transmission from the outset while maintaining adaptability to different channel conditions.
4Productivity
If scanning period is shortened to improve discovery speed, then discovery efficiency increases, but power consumption increases
Solution Approach 1:
The patent implements dynamic scanning period adjustment where the scanning interval is adaptively modified based on signal conditions and discovery requirements. Instead of using a fixed short scanning period that continuously consumes power, the system dynamically adjusts the scanning interval to be shorter when discovery is critical and longer when signal conditions are stable, thereby achieving fast discovery speed while managing power consumption effectively.
