Solution Overview

Problem

Current camouflage devices are limited in their ability to simultaneously counteract multiple types of detectors, such as radar, infrared, and visible ray detectors, making them ineffective in complex environments.

Innovation Solution

An active camouflage device comprising a reflective layer, electrodes, an electrolyte, and an electrochromic layer, along with a control unit and detection unit, which can adjust its operation mode to reflect or absorb electromagnetic waves, infrared rays, and visible rays based on environmental measurements, using materials like gold, silver, and tungsten trioxide to achieve camouflage across multiple spectrums.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a camouflage device uses a single type of detector correspondence (e.g., visible ray only), then the device structure remains simple, but the device cannot effectively counteract multiple types of detectors simultaneously

Engineering Contradiction:
Improvecamouflage effectiveness against multiple detectorsVSAvoidstructure complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent combines multiple functional layers (reflective layer for radar/electromagnetic waves, electrochromic layer for infrared, and semi-transparent layer for visible rays) into a single integrated camouflage device structure. This merging allows the device to simultaneously counteract multiple types of detectors while maintaining a unified, manageable structure rather than requiring separate devices for each detection type.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The camouflage device is designed with multi-functional layers that each handle different types of electromagnetic radiation. The reflective layer handles radar and electromagnetic waves, the electrochromic layer handles infrared detection, and the semi-transparent layer handles visible light detection. This universal design enables a single device to provide comprehensive camouflage across multiple detection spectrums.

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

2Reliability

If the device uses multiple functional layers for different spectrums, then the camouflage effectiveness improves, but the device structure becomes more complex

Engineering Contradiction:
Improvecamouflage effectivenessVSAvoidlayer structure complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The camouflage device is segmented into distinct functional layers, each responsible for a specific spectrum: the reflective layer for radar/electromagnetic waves, the electrochromic layer for infrared, and the semi-transparent layer for visible light. This segmentation allows each layer to be optimized for its specific function while maintaining overall system reliability through coordinated operation of all layers.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The device employs composite material structures where different materials with specific properties are combined in layered form. The reflective layer uses materials that reflect electromagnetic waves, the electrochromic layer uses materials like tungsten trioxide that change optical properties with voltage, and the semi-transparent layer uses materials that selectively transmit and reflect visible light. This composite approach enhances camouflage effectiveness while organizing complexity into manageable functional units.

Inventive Principle:
Principle #40Composite materials

3Adaptability or versatility

If the device uses controllable layers that can change properties, then the adaptability to different environments improves, but the device complexity increases

Engineering Contradiction:
Improveenvironmental adaptabilityVSAvoidcontrol system complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The electrochromic layer is designed to dynamically change its optical properties in response to applied voltage, transitioning between transparent and colored states. This dynamic behavior allows the device to adapt to different environmental conditions and detection scenarios. The semi-transparent layer similarly provides adjustable optical properties, enabling the device to optimize camouflage effectiveness across varying environments without requiring a completely different structure for each condition.

Inventive Principle:
Principle #15Dynamics
