Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional connectors and chokes are used in cable television apparatus, then the apparatus can transmit cable television signals, but the high frequency characteristics are degraded, limiting bandwidth extension
Solution Approach 1:
The patent changes the physical parameters of the choke by directly touching it to the signal transmission unit, reducing the connection path length. This parameter change improves high frequency characteristics while maintaining signal blocking functionality, enabling bandwidth extension without sacrificing reliability.
2Reliability
If the connection path between choke and signal transmission unit is long, then the apparatus is easier to manufacture, but the high frequency characteristics are degraded
Solution Approach 1:
The patent extracts the unnecessary portion of the connection path by making the choke directly touch the signal transmission unit. This eliminates intermediate connection elements that would lengthen the path, thereby improving high frequency characteristics while keeping the manufacturing process simple through direct soldering.
3Adaptability or versatility
If conventional connection methods are used for choke and connector, then the manufacturing process is simple, but the high frequency characteristics are insufficient to provide more services
Solution Approach 1:
The patent modifies the connection method by directly touching the choke to the signal transmission unit and soldering them together. This parameter change in the connection approach improves high frequency characteristics, enabling bandwidth extension and additional services while maintaining manufacturing simplicity through standard soldering techniques.
