Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the data transmission rate is increased to improve throughput, then the transmission performance is improved, but the transmission power and signal quality requirements become more stringent
Solution Approach 1:
The patent implements dynamic rate adaptation by continuously monitoring channel conditions (signal strength, interference levels) and adjusting the transmission rate accordingly. The system transitions from static to dynamic rate selection, allowing the wireless communication device to optimize throughput while maintaining reliable signal quality through real-time adjustments based on actual channel state information.
Solution Approach 2:
The patent changes the transmission rate parameter dynamically based on channel conditions. By varying the transmission rate parameter in response to measured signal quality and interference levels, the system achieves optimal throughput while maintaining reliability. This parameter adaptation resolves the contradiction by allowing high rates when conditions permit and lowering rates when signal quality deteriorates.
2Productivity
If the transmission rate is increased to improve throughput, then the data transmission speed is improved, but the required transmission power increases
Solution Approach 1:
The patent dynamically adjusts the transmission rate based on actual channel conditions and signal quality measurements. Rather than using a fixed high transmission power and rate, the system adapts both rate and power levels to match the actual communication environment, achieving high throughput when possible while reducing power consumption when channel conditions deteriorate.
Solution Approach 2:
The patent changes the transmission rate parameter dynamically based on channel conditions. By varying the transmission rate parameter in response to measured signal quality and interference levels, the system achieves optimal throughput while maintaining reliability. This parameter adaptation resolves the contradiction by allowing high rates when conditions permit and lowering rates when signal quality deteriorates.
3Productivity
If the transmission rate is increased to improve throughput, then the productivity is improved, but the device complexity for rate determination increases
Solution Approach 1:
The patent implements self-service rate determination where the wireless communication device autonomously monitors its own channel conditions and selects appropriate transmission rates without external intervention. The device uses built-in sensors and processors to measure signal quality and automatically adjust rates, reducing the need for complex external rate determination systems while maintaining high throughput.
Solution Approach 2:
The patent employs feedback mechanisms where the device continuously monitors channel conditions (signal strength, interference) and uses this information to adjust transmission rates. This closed-loop feedback system simplifies rate determination by using direct measurements from the communication environment rather than complex predictive models or external control systems.
