Solution Overview

Problem

The increasing availability of drones to private individuals poses challenges for law enforcement and security as they can be used for illegal activities, and existing technologies lack effective methods to detect and counter unwanted drones in real-time.

Innovation Solution

A drone detection system utilizing a LIDAR scanning system to create a three-dimensional model of an environment, geo-locator to tag geo-reference points, and a response planner to identify access paths and plan intercepts, which includes deploying a second drone to intercept the target drone, minimizing collateral damage and optimizing sensor placement to reduce blind spots.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If a LIDAR scanning system is used to create a three-dimensional model of the environment, then the detection precision and tracking capability of drones is improved, but the device complexity and computational requirements increase

Engineering Contradiction:
Improvedetection precisionVSAvoiddevice complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The system performs preliminary scanning of the environment to create a three-dimensional model before drone detection is needed. This pre-established model contains information about terrain, obstacles, and access paths, which is then reused during actual drone detection and interception operations, avoiding the need to generate such complex data in real-time

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system divides the complex detection task into separate functional modules: LIDAR scanning for environmental mapping, geo-locator for positioning, labeler for identifying features of interest, and response planner for interception. Each module handles a specific aspect of the detection process, making the overall complex system more manageable and maintainable

Inventive Principle:
Principle #1Segmentation

2Speed

If the system identifies and intercepts target drones in real-time, then the response time and effectiveness of countermeasures is improved, but the complexity of planning safe paths and minimizing collateral damage increases

Engineering Contradiction:
Improveresponse timeVSAvoidplanning complexity
Core Design Contradiction:
SpeedVSDevice complexity

Solution Approach 1:

The system pre-generates the three-dimensional environmental model with marked features of interest and potential access paths before interception is needed. This allows the response planner to quickly query preprocessed spatial data and generate interception paths without performing complex environmental analysis in real-time, thus maintaining fast response while managing planning complexity

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The three-dimensional environmental model acts as an intermediary data structure that stores preprocessed spatial information about the environment. The response planner queries this model to obtain terrain data, obstacle locations, and access paths, avoiding the need to perform complex geometric calculations directly during the interception decision-making process

Inventive Principle:
Principle #24Intermediary (Mediator)
