Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the cable is bent or compressed during routing, then the cable can be installed in confined spaces, but the impedance drops and signal propagation efficiency deteriorates
Solution Approach 1:
The preform structure is designed in advance with a divider positioned between dielectric materials to create initial spacing between conductors. This preliminary configuration compensates for the impedance drop that will occur when the cable is subsequently bent or compressed during routing, allowing the cable to maintain signal integrity even in confined spaces
Solution Approach 2:
The patent changes the physical parameters of the cable structure by introducing a preform with a divider that increases the distance between conductors. This structural parameter change compensates for the compression effects that occur during cable bending, maintaining optimal impedance characteristics despite the cable's flexible routing capability
2Reliability
If the distance between conductors is increased to compensate for compression, then impedance is maintained, but the cable structure becomes more complex
Solution Approach 1:
The preform structure is prepared in advance with the divider already positioned to create the necessary conductor spacing. This preliminary action ensures that when the cable is installed and compressed during routing, the impedance is already compensated for, maintaining signal quality without requiring complex real-time adjustments
Solution Approach 2:
The divider in the preform structure serves as an intermediary element positioned between the dielectric materials. This intermediary component effectively increases the distance between conductors to maintain impedance while being integrated into the cable structure in a relatively simple manner
