Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If coax cable is used to transmit radio frequency signals, then electromagnetic interference is reduced, but manufacturing cost and complexity increase
Solution Approach 1:
The patent replaces the mechanical coaxial cable transmission system with an integrated digital communication system. The antenna module converts RF signals to digital signals internally, eliminating the need for coax cables and their associated shielding requirements. This substitution resolves the contradiction by achieving interference protection through digital processing rather than physical shielding.
Solution Approach 2:
The patent merges the receiver and processor into a single integrated antenna module. This consolidation eliminates the need for separate coaxial cable routing between distinct receiver and processor units, thereby reducing manufacturing complexity while maintaining electromagnetic interference protection through integrated digital signal processing.
2Reliability
If coax cable is routed separately to shield signals, then signal integrity is improved, but manufacturing cost increases
Solution Approach 1:
The patent replaces the mechanical coaxial cable system with an integrated digital communication architecture. By performing analog-to-digital conversion within the antenna module and using standard digital communication protocols, the system achieves signal integrity without requiring expensive separate coaxial cable routing and shielding installations.
Solution Approach 2:
The integrated antenna module uses standard vehicle wiring for both power and data communication, eliminating the need for dedicated coaxial cables. This multi-functional approach allows existing vehicle wiring harnesses to serve communication purposes, reducing manufacturing costs while maintaining reliable signal transmission through digital protocols.
