Engineering Contradiction Analysis
1Area of stationary object
If duplexers and diplexers are used to switch antennas between different modes and frequency bands, then communication functionality is maintained, but circuit space is wasted and receiver sensitivity is degraded
Solution Approach 1:
The patent merges the functions of multiple switches into a single switchplexer device that can concurrently link multiple ports to a single antenna. This consolidation eliminates the need for separate duplexers and diplexers, reducing circuit space while maintaining the ability to switch between different modes and frequency bands without degrading receiver sensitivity.
Solution Approach 2:
The switchplexer is designed as a universal device that can handle multiple functions: switching between transmit and receive modes, selecting different frequency bands, and managing multiple antenna ports simultaneously. This multi-functionality replaces what previously required separate specialized components, optimizing both space and performance.
2Adaptability or versatility
If traditional switching methods are used, then antenna switching between modes is achieved, but circuit complexity increases and space is wasted
Solution Approach 1:
Multiple switching functions are merged into a single integrated switchplexer device. Instead of using separate switches for different frequency bands and modes, the patent implements a unified device with multiple ports that can be concurrently linked to the antenna, simplifying the overall circuit architecture while maintaining full adaptability.
Solution Approach 2:
The switchplexer employs dynamic control through controlling circuitry that can concurrently close multiple switches based on operational requirements. This dynamic switching capability allows the system to adapt to different modes and frequency bands efficiently without requiring complex static circuit configurations.
3Productivity
If multiple switches are used for concurrent communication in multiple bands, then communication performance improves, but device complexity increases
Solution Approach 1:
The switchplexer implements dynamic switching where the controlling circuitry can concurrently close multiple switches to enable simultaneous communication in multiple frequency bands. This dynamic approach allows the device to scale its complexity only when needed for concurrent operations, rather than maintaining fixed complex circuitry for all possible scenarios.
Solution Approach 2:
The controlling circuitry acts as an intermediary that manages the complexity of concurrent switching operations. It receives control signals and intelligently determines which switches to close, abstracting the complexity from the main communication paths and enabling concurrent multi-band operation without proportionally increasing overall device complexity.

AI summary
A switchplexer is described. The switchplexer includes switches that are coupled to an antenna. The switchplexer also includes ports. Each of the switches is separately coupled to one of the ports. The switchplexer also includes controlling circuitry coupled to the switches. The controlling circuitry concurrently closes at least two of the switches when indicated by a control signal.
