Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If high performance equipment is used to support high frequency bands and complex protocols, then data throughput is improved, but power consumption increases
Solution Approach 1:
The patent implements dynamic adjustment of communication parameters including switching between high and low complexity communication methods, adjusting modulation and coding schemes, and dynamically selecting frequency bands based on channel conditions. This allows the system to adapt performance and power consumption to actual needs rather than operating at fixed high performance levels
Solution Approach 2:
The system changes key communication parameters such as modulation order, coding rate, frequency band selection, and protocol complexity based on channel quality measurements. When channel conditions are poor, the system transitions to more robust but lower throughput parameters, and when conditions are good, it uses higher throughput parameters, thereby optimizing the power-throughput tradeoff
2Adaptability or versatility
If low complexity communication methods are used when signal quality is reduced, then system accessibility is improved, but power consumption is not reduced
Solution Approach 1:
The system dynamically adjusts communication complexity based on channel conditions rather than using fixed low complexity methods. When channel quality improves, the system can switch to higher complexity methods that provide better throughput while still maintaining accessibility for poor channel conditions, thereby reducing unnecessary power consumption from always using low complexity modes
3Productivity
If high complexity protocols are used for high throughput, then data transmission capability is improved, but device performance efficiency deteriorates
Solution Approach 1:
The patent implements dynamic protocol selection and parameter adjustment where the system can switch between high and low complexity communication methods based on actual channel conditions. This allows the device to achieve high data transmission capability when needed while avoiding unnecessary complexity when channel conditions warrant simpler methods, thereby improving overall performance efficiency
