Solution Overview

Problem

The deployment of 5G cellular technology faces challenges in achieving widespread coverage with minimal visual impact, as traditional towers are large and require direct line of sight, leading to potential coverage gaps and aesthetic concerns, especially in high-traffic areas like cities.

Innovation Solution

The use of liquid lens or steerable actuated antennas mounted on moveable surfaces, such as light poles or manhole covers, which can adjust their directionality and curvature to optimize RF links and improve signal strength, utilizing processors to calibrate and focus signals for better transmission speeds and SNR, and incorporating learning machines like neural networks to optimize 5G parameters based on local behaviors.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional 5G towers are deployed to provide widespread coverage, then signal coverage is improved, but visual impact and aesthetic concerns worsen

Engineering Contradiction:
Improvesignal coverageVSAvoidvisual impact
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent divides the 5G network into small cell units distributed across multiple locations (light poles, manhole covers, buildings) rather than using few large towers. This segmentation provides widespread coverage while each unit has minimal visual impact individually.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent transitions from horizontal deployment (large towers spanning wide areas) to vertical deployment (small cells mounted on existing vertical structures like light poles and buildings). This dimensional change enables coverage without requiring prominent horizontal structures.

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

2Reliability

If small cell 5G towers are installed frequently to provide coverage, then signal coverage is improved, but device complexity and deployment difficulty worsen

Engineering Contradiction:
Improvesignal coverageVSAvoiddeployment complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent designs small cell units that can be mounted on multiple types of existing structures (light poles, manhole covers, building facades, street lights). This universal mounting capability reduces deployment complexity by using familiar, already-positioned infrastructure rather than requiring specialized tower installations.

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

Solution Approach 2:

The system uses existing public infrastructure (light poles, manhole covers, buildings) that are already distributed throughout the area. These structures serve dual purposes: their original function plus 5G antenna mounting, eliminating the need to build dedicated tower infrastructure.

Inventive Principle:
Principle #25Self-service

3Speed

If steerable antennas with moveable surfaces are used to optimize RF links, then transmission speed is improved, but device complexity worsens

Engineering Contradiction:
Improvetransmission speedVSAvoidantenna system complexity
Core Design Contradiction:
SpeedVSDevice complexity

Solution Approach 1:

The patent employs liquid lenses with moveable surfaces that can dynamically change curvature to steer antenna beams and optimize RF links. This dynamic adjustment enables adaptive transmission optimization without requiring complex mechanical steering mechanisms.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent uses liquid lenses where the curvature of the lens surface is controlled by hydraulic or pneumatic mechanisms. This allows smooth, continuous adjustment of the antenna beam direction and focus using fluid pressure control rather than complex mechanical actuators.

Inventive Principle:
Principle #29Pneumatics and hydraulics

4Measurement precision

If liquid lenses with moveable surfaces are used to adjust curvature, then signal focusing is improved, but manufacturing precision requirements worsen

Engineering Contradiction:
Improvesignal focusing precisionVSAvoidlens curvature control precision
Core Design Contradiction:
Measurement precisionVSManufacturing precision

Solution Approach 1:

The patent incorporates feedback mechanisms where processors monitor signal quality metrics (RSSI, TSSI, SNR) and automatically adjust the liquid lens curvature to optimize the RF link. This closed-loop control achieves precise signal focusing through iterative adjustment rather than requiring ultra-precise manufacturing tolerances.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The patent changes the physical parameter of the liquid lens (curvature) dynamically during operation to optimize performance. By controlling the lens curvature parameter in real-time based on signal conditions, the system achieves precise focusing without requiring the lens to be manufactured with extreme precision for a fixed shape.

Inventive Principle:
Principle #35Parameter changes
