Solution Overview

Problem

Existing wireless communication systems face challenges in detecting the likelihood of signal interference between different wireless communication systems, particularly in scenarios where asynchronous local 5G wireless communication systems are used in adjacent agricultural lands, leading to radio frequency interference.

Innovation Solution

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Area of stationary object

If multiple wireless communication systems are installed in the same area to expand coverage, then the area of wireless communication coverage is improved, but radio frequency interference between different systems occurs

Engineering Contradiction:

Improvewireless communication coverage areaVSAvoidradio frequency interference

Core Design Contradiction:

Area of stationary objectVSObject-affected harmful factors

Solution Approach 1:

The system performs preliminary detection of informing signals from other wireless communication systems before interference occurs. The base station detects informing signals transmitted by other base stations in adjacent areas, identifies potential interference scenarios, and notifies relevant wireless communication apparatuses in advance to adjust their communication parameters and avoid interference.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system establishes a feedback mechanism where wireless communication apparatuses report received informing signals from other systems back to their own base stations. The base station then notifies other base stations about detected informing signals, creating a closed-loop feedback system that enables continuous monitoring and adjustment of communication parameters to prevent interference while maintaining expanded coverage.

Inventive Principle:

Principle #23Feedback

2Speed

If wireless communication apparatuses transmit signals at high power to extend range, then the speed of communication is improved, but the likelihood of interfering with other systems increases

Engineering Contradiction:

Improvecommunication speedVSAvoidsignal interference

Core Design Contradiction:

SpeedVSObject-generated harmful factors

Solution Approach 1:

The system dynamically changes communication parameters including transmission power based on detected interference conditions. When informing signals from other wireless communication systems are detected, the base station notifies relevant apparatuses to adjust their transmission parameters such as reducing power or changing frequency channels, thereby maintaining high communication speed where possible while preventing interference in overlapping areas.

Inventive Principle:

Principle #35Parameter changes

3Reliability

If base stations transmit informing signals continuously to maintain network visibility, then the reliability of network detection is improved, but the energy consumption increases

Engineering Contradiction:

Improvenetwork detection reliabilityVSAvoidbase station energy consumption

Core Design Contradiction:

ReliabilityVSUse of energy by moving object

Solution Approach 1:

Instead of continuous transmission, the system uses partial action by transmitting informing signals at specific intervals or under specific conditions. Base stations transmit informing signals to notify other systems of their presence and operational parameters, but not continuously, thereby maintaining sufficient network detection reliability while significantly reducing energy consumption compared to continuous transmission.

Inventive Principle:

Principle #16Partial or excessive action
