Solution Overview

Problem

Helicopter exterior lighting systems face inefficiencies in illuminating target objects due to obstacles between the helicopter and the target, limiting visibility under adverse conditions such as night or fog.

Innovation Solution

A helicopter lighting system that includes a docking station and an unmanned aerial vehicle (UAV) with adjustable lighting devices, allowing the UAV to dock and separate from the helicopter, and operate remotely to illuminate targets with adjustable light distribution, including switching between flood and search light modes, and adapting light beam focus and direction.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Illumination intensity

If helicopter-mounted search lights are used to illuminate target objects, then visibility enhancement is achieved, but obstacles between the helicopter and target object interfere with light beams preventing efficient illumination

Engineering Contradiction:
Improvetarget illumination efficiencyVSAvoidobstacle interference
Core Design Contradiction:
Illumination intensityVSObject-affected harmful factors

Solution Approach 1:

The lighting system is segmented into a fixed helicopter platform and a separable UAV component. The UAV can detach from the helicopter and independently position itself to illuminate targets, separating the illumination function from the helicopter body to avoid obstacle interference.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The UAV acts as an intermediary between the helicopter and the target object. It carries the lighting device and positions itself in intermediate locations to deliver light beams to targets that are obscured from the helicopter's direct line of sight by obstacles.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Illumination intensity

If the helicopter changes position to illuminate target objects, then unimpeded light delivery is achieved, but mission continuity is disrupted

Engineering Contradiction:
Improvelight delivery qualityVSAvoidmission interruption
Core Design Contradiction:
Illumination intensityVSLoss of time

Solution Approach 1:

The illumination function is separated from the helicopter by deploying a UAV. The helicopter maintains its position and mission, while the UAV independently adjusts its position to provide optimal illumination, preventing mission disruption.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The UAV provides dynamic positioning capability for the lighting device. It can autonomously or remotely adjust its position in real-time to maintain unimpeded light delivery to moving or stationary targets without requiring the helicopter to move.

Inventive Principle:
Principle #15Dynamics

3Device complexity

If fixed lighting devices are mounted on the helicopter, then simple system structure is maintained, but lighting distribution flexibility is limited

Engineering Contradiction:
Improvesystem structure simplicityVSAvoidlighting distribution flexibility
Core Design Contradiction:
Device complexityVSAdaptability or versatility

Solution Approach 1:

The lighting device transitions from a fixed, static configuration to a dynamic, adjustable system. The UAV carries the lighting device and can position it dynamically, while adjustable optical elements further modify light distribution. This provides flexibility without requiring complex multi-device configurations on the helicopter.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The UAV-based lighting system serves multiple functions: it can illuminate various target types (ground, aerial, moving, stationary), adjust lighting modes (flood, search, spot), and operate in different configurations (docked or separated). This universal capability replaces the need for multiple specialized fixed lighting devices.

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