Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple antennas and communication protocols are installed to support 5G and other mobile communication standards, then communication capability and versatility are improved, but space consumption and device complexity increase
Solution Approach 1:
The patent combines multiple antenna systems and communication protocols into a unified architecture where multiple antennas share common cabling infrastructure. The frontend modules for different protocols (3G, 4G, 5G, WiFi, Bluetooth) are integrated into a consolidated system that uses shared digital transmission lines, reducing the overall space required compared to completely separate systems.
Solution Approach 2:
The patent implements a universal cabling system using digital transmission lines that can carry signals for multiple communication protocols simultaneously. The cable transmission element is designed to be protocol-agnostic, allowing the same physical infrastructure to support various antenna types and communication standards, thereby reducing space consumption while maintaining versatility.
2Reliability
If coaxial cables with intermediate amplifiers are used to cable multiple antennas, then signal transmission reliability is improved, but device complexity and space consumption increase
Solution Approach 1:
The patent replaces the traditional coaxial cable mechanical system with a digital transmission system. Instead of using analog RF signals over coaxial cables with intermediate amplifiers, the system converts antenna signals to digital format and transmits them over digital transmission lines, eliminating the need for complex coaxial cabling infrastructure and intermediate amplifiers while maintaining signal integrity.
Solution Approach 2:
The patent changes the signal transmission parameter from analog RF signals to digital signals. This parameter change enables the use of simpler digital transmission lines instead of complex coaxial cable systems, reducing cabling complexity while maintaining or improving signal transmission reliability through digital signal processing and error correction capabilities.
3Power
If analog high-frequency signals are transmitted over long distances, then signal strength is maintained, but signal loss and interference increase
Solution Approach 1:
The patent applies preliminary action by converting analog high-frequency signals to digital signals at the antenna frontend modules before transmission. This conversion happens at the source, allowing the digital signals to be transmitted over long distances without the signal loss and interference problems that affect analog RF signals over coaxial cables. The digital conversion preserves signal integrity throughout the transmission path.
