Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a higher transmission rate is used to transmit more data, then productivity is improved, but reliability deteriorates due to increased disconnection risk
Solution Approach 1:
The transmission rate is dynamically adjusted based on real-time collision detection results. When collisions are detected, the transmission rate is lowered to improve reliability; when no collisions occur, the rate is increased to maximize productivity. This dynamic adaptation resolves the contradiction by making the transmission rate flexible rather than fixed.
Solution Approach 2:
The system implements feedback control by continuously monitoring transmission status and collision patterns, then adjusting the transmission rate accordingly. The collision detection mechanism provides feedback about channel conditions, which feeds back into transmission rate selection, creating a closed-loop system that balances productivity and reliability.
2Reliability
If a lower transmission rate is used to ensure easier connection, then reliability is improved, but productivity deteriorates due to increased transmission time
Solution Approach 1:
Rather than using a statically low transmission rate, the system dynamically selects transmission rates based on detected collision patterns. This allows the system to achieve reliability when needed (by lowering rates during high collision periods) while maintaining productivity when conditions permit (by using higher rates during low collision periods).
Solution Approach 2:
The transmission rate parameter is changed adaptively based on collision detection results. The system monitors collision patterns and adjusts the transmission rate parameter accordingly, transforming it from a fixed parameter to a dynamically optimized parameter that balances reliability and productivity.
3Reliability
If existing collision reduction techniques are applied, then reliability is improved, but device complexity increases due to redundant control processes
Solution Approach 1:
The patent extracts and implements only the essential collision detection and response functions, removing redundant control processes found in existing techniques. By focusing on core functionality (detecting collisions and adjusting transmission parameters), the system achieves reliability without the overhead of complex master terminal control or multiple redundant mechanisms.
Solution Approach 2:
Each terminal independently performs collision detection and adjusts its own transmission parameters based on detected patterns. This self-service approach eliminates the need for complex centralized control mechanisms, reducing device complexity while maintaining reliability through distributed intelligence.
4Reliability
If master terminal control is implemented to reduce collision, then reliability is improved, but device complexity increases due to centralized control structure
Solution Approach 1:
The patent implements a self-service mechanism where each terminal independently detects collisions and adjusts its transmission behavior. This distributed approach replaces the centralized master terminal control structure, reducing overall system complexity while maintaining collision reduction effectiveness through individual terminal autonomy.
Solution Approach 2:
The collision control function is segmented and distributed to individual terminals rather than centralized in a master terminal. Each terminal independently performs detection and adjustment, dividing the control function into autonomous units that operate independently, thereby reducing the complexity of the overall control structure.
