Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple antennas are used to transmit and receive multiple carrier signals in carrier aggregation, then data throughput can be increased, but device complexity and hardware requirements increase
Solution Approach 1:
The patent combines multiple carrier signals into a single antenna for transmission and merges received signals from a single antenna into multiple carrier streams for reception. The transmitting amplifier combines multiple carrier signals before transmission, and the receiving amplifier separates received signals into multiple carrier streams, eliminating the need for multiple antennas while maintaining carrier aggregation functionality.
Solution Approach 2:
A single antenna is made to perform multiple functions by transmitting and receiving multiple carrier signals simultaneously. The transmitting amplifier and receiving amplifier enable this single antenna to handle multiple carriers, making the antenna system universal rather than dedicated to specific carriers.
2Productivity
If multiple antennas are deployed for carrier aggregation, then transmission capacity increases, but hardware cost and device size increase
Solution Approach 1:
The patent merges multiple carrier transmission functions into a single antenna system. The transmitting amplifier combines multiple carrier signals into one transmission stream, and the receiving amplifier separates received signals into multiple carrier streams, reducing the quantity of antenna hardware components from multiple antennas to a single antenna.
3Reliability
If separate amplifiers are used for each carrier signal, then signal quality is maintained, but device complexity and power consumption increase
Solution Approach 1:
The patent employs universal amplifiers that can handle multiple carrier signals. The transmitting amplifier processes multiple carrier signals simultaneously for transmission, and the receiving amplifier processes multiple received carrier signals simultaneously, making these amplifiers multi-functional rather than dedicated to single carriers, thereby reducing device complexity while maintaining signal quality.
