Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If discovery frames or beacons transmit a large amount of data to ensure comprehensive information coverage, then information completeness is improved, but bandwidth utilization deteriorates due to transmission of data that may not be used
Solution Approach 1:
The patent extracts and transmits only the necessary connection setup information elements and service identifiers in discovery frames, removing unnecessary data. This selective extraction ensures information completeness for network discovery while improving bandwidth utilization by transmitting only relevant data that devices actually need to use.
2Loss of information
If discovery frames transmit comprehensive data to ensure all nodes receive useful information, then information availability is improved, but power consumption deteriorates due to inefficient bandwidth usage
Solution Approach 1:
The patent applies data extraction by including only essential connection setup information elements and service identifiers in discovery frames. This reduces the overall data transmission volume while maintaining information availability for network discovery, thereby reducing power consumption associated with transmitting and processing unnecessary data.
3Reliability
If traditional discovery frames transmit all possible data to ensure robust network discovery, then discovery reliability is improved, but communication efficiency deteriorates due to suboptimal bandwidth usage
Solution Approach 1:
The patent extracts and transmits only the critical connection setup information elements and service identifiers required for reliable network discovery. This selective approach maintains discovery reliability by including essential data while improving communication efficiency by eliminating redundant information that does not contribute to the discovery process.
