Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If coils of multiple transport ports are disposed in the same transformer element to reduce production cost, then manufacturing cost is reduced, but signal quality is degraded due to interference between adjacent transport ports
Solution Approach 1:
The patent converts the harmful interference signal into a useful cancellation signal by comparing seed information from different transport ports. When interference is detected through seed comparison, the system generates a control signal to cancel the identified interference, transforming the harmful effect into a beneficial cancellation mechanism that improves signal quality while maintaining cost-effective transformer design
Solution Approach 2:
The patent implements a feedback mechanism where the seed comparator continuously monitors interference conditions by comparing seed information from multiple transport ports. Based on the comparison results, the control unit dynamically adjusts cancellation signals, creating a closed-loop system that automatically responds to and corrects interference conditions in real-time
2Object-affected harmful factors
If seed comparators and control units are added to eliminate interference, then signal quality is improved, but device complexity increases
Solution Approach 1:
The patent applies local quality by implementing seed comparison and interference cancellation only at specific locations where interference occurs - namely at the transformer elements handling multiple transport ports. Rather than applying complex interference mitigation across the entire system, the solution focuses computational resources locally where needed, comparing seeds only for ports sharing the same transformer element and generating cancellation signals only for identified interference paths
