Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the communication rate is dynamically changed according to communication environment, then the data transfer efficiency is optimized, but the communication stability for streaming data deteriorates
Solution Approach 1:
The patent applies dynamics by making the communication rate adjustable and switchable between different levels (higher rate for efficiency, quality assurance level for stability). The system dynamically selects the appropriate rate based on whether streaming data is detected, allowing optimal performance for different data types while maintaining stability for real-time applications.
Solution Approach 2:
The invention changes the communication rate parameter based on the type of data being transmitted. When streaming data is detected, the system switches to a quality assurance level that ensures stable communication. For non-streaming data, it uses higher communication rates to maximize transfer efficiency. This parameter change resolves the contradiction by adapting the rate to the specific requirements of the data being transmitted.
2Productivity
If the communication rate is increased to optimize transfer efficiency, then the data transfer speed improves, but the communication quality under varying radio signal conditions deteriorates
Solution Approach 1:
The system changes the communication rate parameter based on data type and radio signal conditions. For streaming data with real-time requirements, it selects a quality assurance level that ensures reliable communication even under varying signal conditions. For other data types, it uses higher rates to maximize speed when conditions permit.
Solution Approach 2:
The patent implements feedback mechanisms to monitor communication quality and adjust the rate accordingly. The system detects whether streaming data is being transmitted and adjusts the communication rate to maintain appropriate quality levels, ensuring that real-time applications receive adequate service while allowing higher rates for non-critical data.
3Reliability
If the communication rate is decreased to maintain communication quality, then the stability improves, but the data transfer efficiency deteriorates
Solution Approach 1:
The invention dynamically changes the communication rate parameter based on the type of data being transmitted. When streaming data is detected, it uses a quality assurance level that prioritizes stability. When other data types are transmitted, it switches to higher communication rates to maximize efficiency. This selective parameter change resolves the contradiction by applying different rate strategies to different data types.
Solution Approach 2:
The system makes the communication rate dynamic rather than fixed, allowing it to adapt to the specific requirements of the transmitted data. This dynamic adjustment enables the system to achieve both high efficiency and high stability as needed, depending on the data type and communication conditions.
