Solution Overview

Problem

Existing electronically tunable antennas lack precise adjustment capabilities for downtilt angles, especially in horizontal orientation and mechanical tilt, due to ineffective monitoring of physical orientation data, leading to installation and maintenance challenges, particularly after construction changes or environmental factors like typhoons.

Innovation Solution

Incorporating an attitude sensing device with a three-axis magnetic sensor and gravity acceleration sensor, connected to an antenna control unit, which allows for real-time monitoring and adjustment of electrical downtilt, horizontal orientation, and mechanical tilt angles, along with a remote control unit and hand-held terminal for convenient adjustments and data storage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If electronically tunable antenna is used to adjust downtilt angle, then coverage area can be reduced and interference decreased, but mechanical tilt angle and horizontal orientation cannot be monitored or adjusted remotely

Engineering Contradiction:

Improveremote adjustment capabilityVSAvoidorientation data monitoring

Core Design Contradiction:

Ease of operationVSLoss of information

Solution Approach 1:

The patent replaces mechanical orientation adjustment and monitoring systems with electronic sensors (accelerometers, gyroscopes, magnetometers) and remote communication systems. This allows the antenna's mechanical tilt angle and horizontal orientation to be monitored and adjusted remotely through electronic means, resolving the contradiction between ease of remote operation and information loss.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent implements feedback mechanisms by continuously monitoring the antenna's orientation data using sensors and transmitting this information remotely. This feedback loop enables real-time monitoring of mechanical tilt angle and horizontal orientation, allowing operators to detect and correct deviations without physical presence at the antenna site.

Inventive Principle:

Principle #23Feedback

2Reliability

If construction changes or environmental factors occur, then antenna mounting position deviates, but timely detection and adjustment cannot be made

Engineering Contradiction:

Improveinstallation accuracyVSAvoiddetection and adjustment time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The patent establishes preliminary monitoring capabilities by installing sensors that continuously track orientation data from the beginning. This preliminary action ensures that any deviations caused by construction changes or environmental factors are detected immediately, eliminating detection delays and enabling prompt adjustments to maintain installation accuracy.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent implements continuous monitoring of orientation data through always-active sensors and continuous data transmission. This continuity ensures that deviations are detected in real-time rather than periodically, allowing immediate response to construction changes or environmental factors and maintaining reliable installation accuracy without time loss.

Inventive Principle:

Principle #20Continuity of useful action

3Area of stationary object

If downward angle exceeds 15°, then coverage distance shortens significantly, but directivity pattern shape changes little

Engineering Contradiction:

Improvecoverage areaVSAvoiddirectivity pattern precision

Core Design Contradiction:

Area of stationary objectVSManufacturing precision

Solution Approach 1:

The patent applies dynamics by making the antenna's downtilt angle adjustable and controllable through electronic means. Instead of a fixed mechanical tilt, the system can dynamically adjust the electrical downtilt angle to optimize the balance between coverage area reduction and directivity pattern precision, allowing flexible adaptation to different operational requirements.

Inventive Principle:

Principle #15Dynamics
