Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If separate transmission and reception antennas are used for dual-polarized antennas, then wireless signal transmission and reception functions are achieved, but the physical space required increases and device size increases

Engineering Contradiction:
Improvewireless signal transmission and reception functionVSAvoidphysical space required
Core Design Contradiction:
ReliabilityVSArea of stationary object

Solution Approach 1:

The patent combines separate transmission and reception antennas into a single integrated antenna structure. The antenna element serves both transmission and reception functions simultaneously, eliminating the need for separate antenna structures and reducing the physical space required in the wireless communication device.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The antenna is designed to perform multiple functions - both transmission and reception of wireless signals with dual polarization capabilities. This multi-functional design allows a single antenna to replace what would traditionally require separate specialized antennas for each function.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Reliability

If separate transmission and reception antennas are used, then wireless communication functions are achieved, but the number of components increases and device complexity increases

Engineering Contradiction:
Improvewireless communication functionVSAvoidnumber of components
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent merges multiple antenna components into a single integrated antenna structure that handles both transmission and reception. This consolidation reduces the total number of components in the wireless communication device while maintaining full dual-polarized communication functionality.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The integrated antenna is designed to universally handle multiple communication functions including transmission, reception, and dual polarization operations, thereby reducing the need for separate specialized components for each function.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Area of stationary object

If a single antenna is used for simultaneous transmission and reception, then device size is reduced, but signal interference between transmission and reception may occur

Engineering Contradiction:
Improvedevice sizeVSAvoidsignal interference
Core Design Contradiction:
Area of stationary objectVSObject-generated harmful factors

Solution Approach 1:

The antenna structure is segmented into distinct feed zones - a first feed zone for transmission signals and a second feed zone for reception signals. This spatial segmentation within the single antenna structure helps isolate transmission and reception signal paths, reducing mutual interference while maintaining compact dimensions.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Different regions of the antenna are assigned different functional qualities - the first feed zone is optimized for transmission with appropriate impedance and radiation characteristics, while the second feed zone is optimized for reception with different impedance matching and signal coupling characteristics. This local differentiation reduces interference between transmit and receive functions.

Inventive Principle:
Principle #3Local quality

AI summary

A transceiver includes an antenna configured to transmit a first wireless signal based on a transmission signal and receive a second wireless signal, the second wireless signal including a reflected first wireless signal from an object and the antenna transmitting the first wireless signal and receiving the second wireless signal at the same time. A transmission circuit is configured to generate the transmission signal and output the transmission signal to a first side of the antenna. A reception circuit is configured to receive a reception signal from a second side of the antenna, the antenna outputting the reception signal based on the second wireless signal. The first side is different from the second side.
