Solution Overview

Problem

Current wireless communication infrastructure faces challenges such as incomplete network coverage, high costs, inefficiencies, and increased RF pollution, particularly with ground-based antennas leading to potential health hazards due to excessive RF exposure.

Innovation Solution

An airborne wireless communication system utilizing a fleet of unmanned aerial vehicles (UAVs) with a distributed communication payload, including air-to-user, air-to-air, and air-to-ground link equipment, operating at high altitudes to provide comprehensive and efficient wireless communication services while minimizing RF exposure on the ground.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Area of stationary object

If ground-based antennas are increased in number and density to expand network coverage, then network coverage and capacity are improved, but RF exposure to hazardous levels increases

Engineering Contradiction:
Improvenetwork coverage areaVSAvoidRF exposure
Core Design Contradiction:
Area of stationary objectVSObject-affected harmful factors

Solution Approach 1:

The patent transitions the communication infrastructure from the ground plane to the aerial dimension by deploying balloons at high altitudes (stratosphere/ionosphere boundary). This dimensional shift allows coverage of vast ground areas from elevated positions, reducing the need for dense ground-based antenna installations and consequently lowering RF exposure on the ground while expanding network coverage.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

Solution Approach 2:

The patent divides the communication network into multiple independent balloon nodes distributed across the sky, each providing localized coverage. This segmentation allows the system to achieve wide area coverage through distributed nodes rather than relying on high-density ground infrastructure, thereby reducing overall RF exposure while maintaining comprehensive coverage.

Inventive Principle:
Principle #1Segmentation

2Area of stationary object

If satellite communication systems are deployed to provide coverage, then coverage area is improved, but system cost and signal delay increase

Engineering Contradiction:
Improvecoverage areaVSAvoidsystem cost
Core Design Contradiction:
Area of stationary objectVSDevice complexity

Solution Approach 1:

The patent employs commercially available weather balloons as temporary, disposable communication platforms rather than investing in expensive, long-lived satellite infrastructure. These balloons can be deployed and retired as needed, providing cost-effective coverage for specific events or locations without the prohibitive costs of satellite deployment and maintenance.

Inventive Principle:
Principle #27Cheap short-living objects (Disposable)

Solution Approach 2:

The patent changes the operational altitude parameter from ground level or satellite orbit to the stratospheric/ionospheric boundary (approximately 30-50 km altitude). This parameter change enables line-of-sight communication over large ground areas with lower signal delay compared to satellites, while using much simpler and cheaper balloon technology.

Inventive Principle:
Principle #35Parameter changes

3Power

If optical fiber networks are installed to deliver broadband services, then transmission capacity is improved, but deployment cost and complexity increase

Engineering Contradiction:
Improvetransmission capacityVSAvoiddeployment complexity
Core Design Contradiction:
PowerVSDevice complexity

Solution Approach 1:

The patent replaces the mechanical installation process of optical fiber networks with wireless communication through balloon-mounted equipment. Instead of physically laying cables across terrain, the system uses radio frequency communication from aerial platforms, eliminating the need for complex civil engineering work while providing comparable transmission capacity for broadband services.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)
