Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a radio is configured with predefined settings for specific wireless technologies, then communication compatibility with devices using those technologies is improved, but the radio's adaptability to changing wireless conditions and technologies deteriorates
Solution Approach 1:
The patent implements a dynamic radio configuration system where the radio can automatically adjust its operating parameters (frequencies, modulation schemes, power levels) based on real-time wireless conditions. The system includes a configuration manager that receives status information about wireless conditions and automatically selects appropriate configurations from a predefined set, enabling the radio to adapt dynamically without requiring manual reconfiguration or complex real-time computation.
2Adaptability or versatility
If multiple radios are included to support different wireless technologies, then communication versatility is improved, but device complexity and cost increase
Solution Approach 1:
The patent implements a universal radio design where a single radio component can perform multiple wireless communication functions by switching between different predefined configurations. The configuration manager enables the same physical radio to operate with different wireless technologies (e.g., Wi-Fi, Bluetooth, cellular) by loading appropriate configuration parameters, eliminating the need for separate dedicated radios for each technology while maintaining full versatility.
3Reliability
If the radio adapts to low signal-to-noise ratio by decreasing bit rate or increasing transmitted signal power, then communication reliability is improved, but energy consumption increases
Solution Approach 1:
The patent pre-configures the radio with multiple predefined operating parameters including various bit rates and transmitted signal power levels that are optimized for different wireless conditions. When the configuration manager detects poor signal-to-noise ratio, it automatically selects a pre-configured setting with lower bit rate and higher power level from the predefined set, rather than computing optimal parameters in real-time. This preliminary preparation of configuration options enables reliable adaptation while minimizing computational energy consumption.
Data Source
AI summary
A computer with a software defined radio that can be configured based on a wireless technology specification. The computer may negotiate with a second computer that also includes a software defined radio to define a set of wireless technology specifications and trigger events indicating when each of the wireless technology specifications is to be used. As the computers communicate, if a trigger event occurs, both computers may reconfigure their software defined radios using a different specification in the set. By appropriately defining the wireless technology specifications in the set and the trigger events, the computers can operate with configurations that allow communication despite events that might otherwise disrupt communication between the computers.
