Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for detecting and controlling low-flying aircraft are inefficient and costly, and existing cellular networks lack the capability to reliably monitor air traffic at very low altitudes without requiring extensive infrastructure modifications.
Innovation Solution
Utilizing existing cellular mobile phone network antenna masts equipped with receiving devices for aircraft transponder signals, which enable efficient detection and control of low-flying aircraft by determining their three-dimensional geographic position through triangulation and trilateration, and using this data to activate/deactivate aviation obstruction lights.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If receiving devices are integrated into existing cellular antenna masts, then the cost and complexity of deploying air traffic monitoring infrastructure is reduced, but the detection capability for low-flying aircraft may be compromised due to antenna orientation
Solution Approach 1:
The patent integrates aircraft transponder signal receiving devices into existing cellular mobile phone antenna masts, allowing the same infrastructure to serve both cellular communication and air traffic monitoring functions. This multi-functional approach reduces deployment costs by reusing existing mast structures, power supplies, and locations while adding aviation safety capabilities.
Solution Approach 2:
The patent specifies that receiving antennas should be horizontally aligned to optimize detection of low-flying aircraft, distinguishing the antenna orientation requirements for different detection purposes. This local quality adjustment ensures that specific antenna elements are oriented appropriately for their intended function (horizontal for low-altitude detection) while maintaining the overall mast structure.
2Measurement precision
If horizontally aligned receiving antennas are used, then detection efficiency for low-flying aircraft is improved, but detection capability for high-flying aircraft is reduced
Solution Approach 1:
The patent applies different antenna orientations for different detection purposes: horizontally aligned receiving antennas are used specifically for detecting low-flying aircraft (below 500 meters), while the system acknowledges that vertically aligned antennas would be needed for high-flying aircraft. This localized optimization ensures each antenna type performs its specific function effectively.
Solution Approach 2:
The patent focuses on optimizing detection for the most critical scenario - low-flying aircraft - by using horizontally aligned antennas. While this orientation is less effective for high-altitude detection, the system prioritizes the partial function of detecting low-altitude aircraft where the risk of collision with obstacles is highest, accepting that high-altitude detection is less critical for obstacle lighting control.
3Loss of information
If transponder signals are used for aircraft detection, then altitude and location information can be obtained, but the system fails when transponders do not transmit or signals are blocked
Solution Approach 1:
The patent employs multiple receiving devices distributed across different locations to monitor transponder signals from aircraft. By having redundant receiving paths and multiple detection points, the system can cross-verify signal reception and maintain detection capability even if one receiver fails or signals are blocked in certain areas, improving overall system reliability.
4Reliability
If multiple receiving devices are deployed to improve detection reliability, then the cost and complexity of the system increases
Solution Approach 1:
The patent combines air traffic monitoring receiving devices with existing cellular antenna masts, merging two separate functions (cellular communication and aircraft detection) into a single integrated infrastructure. This reduces the number of separate structures needed and simplifies deployment compared to building dedicated monitoring towers.
Solution Approach 2:
By making the antenna masts multi-functional (serving both cellular and aviation monitoring purposes), the patent reduces the need for separate dedicated infrastructure. The same mast structure, power supply, and location serve dual purposes, reducing overall system complexity despite deploying multiple receiving devices for reliability.
