Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If high-frequency signals are transmitted along conductive lines, then signal transmission between vehicles is enabled, but line losses increase significantly
Solution Approach 1:
The patent applies parameter changes by converting high-frequency signals to lower frequencies using frequency reduction modules. This changes the frequency parameter of the signal, which directly reduces line losses in conductive lines while maintaining signal transmission capability between vehicles
2Length of stationary object
If high-frequency signals are transmitted over long distances, then communication range is extended, but signal attenuation increases
Solution Approach 1:
The patent uses frequency reduction modules to change the frequency parameter of signals before transmission. By lowering the frequency, the signals experience reduced attenuation over long cable lengths, enabling extended communication range without significant signal loss
3Reliability
If high-frequency analog signals are transmitted, then signal fidelity is maintained, but line losses increase
Solution Approach 1:
The patent replaces analog signal transmission with digital signal transmission. By converting analog signals to digital form using analog-to-digital converters, the system maintains signal fidelity through digital processing while enabling the use of frequency reduction to minimize line losses in the transmission medium
