Solution Overview

Problem

Existing technologies face challenges in efficiently transmitting and receiving large amounts of wireless data between distributed elements using array antennas, particularly in dynamic environments where the positions of the antennas change in real time, such as with drones in modern warfare scenarios.

Innovation Solution

A method and system for distributed beamforming that determines a master node among a plurality of distributed nodes based on location information, signal-to-noise ratio, and transmission efficiency, forming a data transmission and reception channel, and configuring a communication method to enable stable wireless data transmission and reception between the master node and slave nodes.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If distributed beamforming is implemented using multiple moving nodes (drones), then wireless data transmission capability is improved, but system stability deteriorates due to real-time position changes

Engineering Contradiction:
Improvewireless data transmission capabilityVSAvoidsystem stability
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The patent implements dynamic master node selection where any distributed node can become the master node based on real-time transmission efficiency metrics. This dynamic adaptation allows the system to maintain stability despite node movement, as the master node identity changes optimally rather than remaining fixed. The system continuously evaluates transmission efficiency and reassigns master node status to maintain optimal performance in dynamic environments.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent changes the parameter of master node selection from static (fixed assignment) to dynamic (based on transmission efficiency). By evaluating transmission efficiency metrics and selecting the optimal node as master, the system adapts to real-time conditions including node position changes, thereby maintaining reliability while preserving the productivity benefits of distributed beamforming.

Inventive Principle:
Principle #35Parameter changes

2Device complexity

If a fixed master node is designated in advance, then device complexity is reduced, but transmission efficiency deteriorates when node positions change

Engineering Contradiction:
Improvenode configuration complexityVSAvoidtransmission efficiency
Core Design Contradiction:
Device complexityVSProductivity

Solution Approach 1:

The patent implements a feedback mechanism where transmission efficiency is continuously evaluated and used to determine master node selection. The system monitors transmission efficiency metrics and feeds this information back into the node configuration process, allowing dynamic optimization of the master node assignment based on current operational conditions rather than relying on predetermined configurations.

Inventive Principle:
Principle #23Feedback

3Productivity

If master node is dynamically selected based on transmission efficiency, then transmission efficiency is improved, but device complexity increases

Engineering Contradiction:
Improvetransmission efficiencyVSAvoidnode management complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent implements self-service where distributed nodes autonomously evaluate their own transmission efficiency and compete to become the master node. Each node independently calculates its transmission efficiency metrics and can transition to master node status without requiring complex centralized control or manual configuration, thereby achieving dynamic optimization with manageable complexity.

Inventive Principle:
Principle #25Self-service
