Solution Overview

Problem

Unmanned aerial vehicles (UAVs) face challenges in low-light conditions due to the decline in illumination with distance, and existing stationary remote lights are difficult to reconfigure or move.

Innovation Solution

An aerial imaging system comprising a first UAV with a camera and a second UAV that can dock and deploy to provide adjustable illumination, allowing the second UAV to fly independently to maintain optimal lighting for the camera, using processor determination and proximity sensors to maintain position relative to the target.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Illumination intensity

If a built-in flash or onboard light is used as a primary light source, then illumination is provided for the camera, but the illumination intensity declines with distance from the target

Engineering Contradiction:
Improveillumination intensityVSAvoiddistance
Core Design Contradiction:
Illumination intensityVSLength of moving object

Solution Approach 1:

The system divides the illumination function into a separate modular component (second UAV with light source) that can be independently positioned. This allows the light source to be segmented from the camera platform, enabling the light to be placed closer to the target while the camera maintains its imaging position, thereby resolving the contradiction between illumination intensity and distance.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

A second UAV acts as an intermediary carrier for the light source, positioned between the first UAV (camera platform) and the target. This intermediary allows the illumination function to be decoupled from the imaging function, enabling optimal positioning of the light source close to the target to maintain high illumination intensity regardless of camera-to-target distance.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Illumination intensity

If stationary remote lights are used to illuminate a scene, then illumination is provided, but the lights require advanced setup and cannot be easily reconfigured or moved

Engineering Contradiction:
ImproveilluminationVSAvoidreconfiguration capability
Core Design Contradiction:
Illumination intensityVSEase of operation

Solution Approach 1:

The system transforms the static, fixed-position remote lights into a dynamic, mobile illumination platform using a second UAV that can fly to and from the target area. This dynamic positioning capability allows the light source to be easily reconfigured and moved between different locations without requiring advanced setup procedures, resolving the contradiction between providing illumination and maintaining ease of operation.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The second UAV with the light source can autonomously navigate to the target area and position itself optimally for illumination, reducing the need for manual setup and reconfiguration by operators. The system serves itself by using autonomous flight capabilities to handle the positioning and deployment of the illumination source, thereby improving ease of operation while maintaining effective illumination.

Inventive Principle:
Principle #25Self-service

3Adaptability or versatility

If the second UAV flies independently from the first UAV, then adjustable illumination is provided, but autonomous operation requires complex positioning control

Engineering Contradiction:
Improveadjustable illuminationVSAvoidpositioning control system
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The first UAV's camera captures images that serve as feedback to determine the position and illumination effectiveness of the second UAV. This visual feedback loop allows the system to automatically adjust the second UAV's position and the light source's orientation to achieve optimal illumination, reducing the complexity of positioning control by using image-based feedback rather than complex manual or pre-programmed control systems.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The first UAV's camera serves multiple functions: it captures the target scene for imaging purposes and simultaneously provides visual feedback for controlling the second UAV's illumination positioning. This multi-functionality reduces system complexity by reusing existing components for multiple purposes, eliminating the need for separate positioning sensors or control systems on the second UAV.

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