Solution Overview

Problem

Helicopter search lights require manual adjustment to track moving objects, which can be hazardous, especially in difficult terrain or adverse weather conditions, as pilots must simultaneously control the light direction and the helicopter.

Innovation Solution

A system comprising a search light connected to a camera and a processor with an object detection module that automatically adjusts the search light's direction based on image analysis, allowing for autonomous tracking of anomalous behavior.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If manual adjustment of search light direction is used, then the system is simpler and easier to manufacture, but the pilot workload increases and safety decreases

Engineering Contradiction:
ImprovesafetyVSAvoidsystem complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The search light system performs self-tracking by automatically detecting and following moving objects using image processing algorithms. The system monitors its own field of view and autonomously adjusts the search light direction without requiring external manual control, thereby reducing pilot workload while maintaining system functionality.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent replaces manual mechanical control of the search light with an automated optical-electronic system. Image capture devices and processors substitute for manual visual observation and mechanical adjustment, using digital image analysis to automatically determine and track moving objects, thereby eliminating the need for continuous manual intervention.

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

2Measurement precision

If automated object detection and tracking is implemented, then tracking precision improves, but device complexity increases

Engineering Contradiction:
Improvetracking precisionVSAvoidsystem complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The system continuously captures images, processes them to detect moving objects, and uses the detection results to automatically adjust the search light direction. This closed-loop feedback mechanism ensures continuous tracking of anomalous objects with high precision, maintaining accurate illumination on moving targets throughout their motion.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The patent introduces an image processing module as an intermediary between the search light system and the moving objects. This intermediary automatically analyzes captured images, identifies anomalous behavior patterns, and generates control signals for search light positioning, thereby achieving precise tracking without direct manual intervention.

Inventive Principle:
Principle #24Intermediary (Mediator)
