Solution Overview

Problem

Existing aerial target marking technologies, such as gas or fuel burners and radio emitters, are ineffective in providing a narrow-band infrared radiation compatible with anti-aircraft defense missiles, and lack precise signal calibration and location.

Innovation Solution

A towed IR flare system with a dual IR radiation source, secured by steel cables and controlled by an electronic unit, emits a narrow-band infrared signal compatible with anti-aircraft defense missiles, allowing precise calibration and location.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If conventional heat sources (gas or fuel burners) are used for marking aerial targets, then the device structure is simple, but the radiation source cannot emit in a narrow band of the spectrum compatible with anti-aircraft defense missiles

Engineering Contradiction:
Improvespectral compatibilityVSAvoiddevice structure
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The system uses multiple independent IR flares (at least two) that can be separated and deployed individually. Each flare contains its own combustion chamber and infrared emitter, allowing the system to achieve spectral compatibility through multiple specialized sources rather than a single complex source, resolving the contradiction between adaptability and device complexity.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent introduces steel cables as intermediaries to deploy and position the IR flares. The cables allow the flares to be separated from the main aerial target and positioned at optimal distances for marking, enabling spectral compatibility without requiring the main target structure itself to generate the infrared radiation.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Measurement precision

If conventional radio emitters are used for marking aerial targets, then the device structure is relatively simple, but the signal cannot be precisely calibrated and located

Engineering Contradiction:
Improvesignal calibration precisionVSAvoidcontrol system complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The system incorporates control units that can monitor and adjust the deployment and operation of the IR flares. This feedback mechanism allows for precise calibration of the infrared signal intensity and positioning, ensuring the marking signal is optimally calibrated for detection by anti-aircraft defense missiles while maintaining manageable system complexity through automated control.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The IR flares are pre-positioned and secured to the aerial target before deployment. The steel cables are pre-attached and configured to deploy the flares to predetermined optimal positions. This preliminary preparation ensures that when the flares are activated, they are already in the correct location and configuration for precise signal calibration without requiring complex real-time adjustment mechanisms.

Inventive Principle:
Principle #10Preliminary action

3Productivity

If a single IR radiation source is used, then the device structure is simple, but the marking effectiveness at various distances (short, medium, and long) is insufficient

Engineering Contradiction:
Improvemarking effectivenessVSAvoidradiation source configuration
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The system divides the radiation source into multiple independent IR flares that can be deployed separately. This segmentation allows each flare to cover different distance ranges (short, medium, and long), with the combined effect providing comprehensive marking effectiveness across all ranges without requiring a single overly complex multi-range radiation source.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent extends the marking capability from a single-point source to a distributed multi-point source configuration. By deploying multiple flares at different positions and distances from the aerial target, the system creates a three-dimensional infrared marking field that enhances detectability and effectiveness across various detection ranges, transforming a one-dimensional limitation into a three-dimensional solution.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)
