Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If a single antenna is used for both transmitting and receiving signals, then the hardware space is reduced, but the circuit design becomes more complicated to prevent intermediation distortion
Solution Approach 1:
The patent implements a switch connector that dynamically changes the antenna configuration from single-antenna mode to dual-antenna mode based on operational requirements. This dynamic reconfiguration allows the system to adapt between compact single-antenna operation (saving space) and separated transmit/receive antenna operation (reducing circuit complexity and intermediation distortion), thereby resolving the contradiction between hardware space and circuit design complexity.
2Device complexity
If two antennas are used simultaneously for transmitting and receiving, then circuit design is simplified and intermediation distortion is reduced, but the hardware space increases
Solution Approach 1:
The switch connector serves multiple functions: it acts as a connector in single-antenna mode and as a switching mechanism for dual-antenna mode. The same physical hardware (switch connector) enables both single-antenna and dual-antenna configurations, making the system universal and adaptable to different operational requirements without requiring separate hardware for each mode, thus avoiding permanent increase in hardware space.
3Adaptability or versatility
If a switch connector is added to enable antenna switching, then operational flexibility is improved, but device complexity increases
Solution Approach 1:
The patent merges the switching function with the existing antenna connector structure. The switch connector integrates the switching mechanism and connector functions into a single component, rather than adding a separate switching device. This merging approach enables operational flexibility (single or dual antenna mode) while minimizing the increase in device complexity by combining multiple functions into one element.

AI summary
An expandable wireless transceiver is provided. The expandable wireless transceiver includes an antenna, a receiver, a transmitter and a switch connector. The antenna detects an electromagnetic signal in surrounding space and receives a signal with a first central frequency according to the detection result. The receiver receives the signal based on the detection result of the antenna. The transmitter outputs a radio-frequency signal. A third connection terminal of the switch connector provides a connective path to an expansion antenna. According to the coupling condition of the third connection terminal, the switch connector delivers the radio-frequency signal to its second connection terminal or third connection terminal. Thus, the radio-frequency signal with a second central frequency is transmitted to surrounding space through the antenna or the expansion antenna, wherein the second central frequency and the first central frequency are both in a specific band.
