Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing 2D camouflage technologies lack structural support and are difficult to fit closely to the contour map of the camouflaged object, making them hard to implement effectively.

Innovation Solution

A spatially adjustable exterior coating comprising a cohered heterogeneous combination of films and pasted layers, which can be deposited on an object's surface to provide multispectral camouflage, allowing for regional adjustment and customization of camouflage profiles to fit the object's specific sections and environmental conditions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If 2D camouflage covers are used, then visibility-related attributes can mimic the background, but the covers lack structural support and are difficult to fit closely to the object's contour

Engineering Contradiction:

Improveease of fitting camouflage coverVSAvoidstructural support of camouflage cover

Core Design Contradiction:

Ease of manufactureVSReliability

Solution Approach 1:

The patent applies flexible thin films as the base structure for the camouflage coating, allowing the coating to conform to complex object contours while maintaining structural integrity. The flexible nature of the thin film enables it to adapt to curved and irregular surfaces without requiring rigid structural support.

Inventive Principle:

Principle #30Flexible shells and thin films

Solution Approach 2:

The patent uses composite material structures combining multiple functional layers (adhesive layer, infrared-reflective layer, visible-light-absorbing layer) integrated into a single coating system. This composite structure provides both the necessary structural support and the camouflage functionality simultaneously, eliminating the need for separate structural supports.

Inventive Principle:

Principle #40Composite materials

2Adaptability or versatility

If uniform camouflage coating is applied, then the object gains basic camouflage, but it cannot adapt to different environmental conditions and object sections

Engineering Contradiction:

Improveadaptability to environmental conditionsVSAvoidcomplexity of spatially adjustable coating

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent implements local quality by applying different camouflage properties to different regions of the object surface. The coating system includes spatially variable layers with different optical and thermal properties tailored to specific object sections and their corresponding environmental exposure conditions, enabling localized adaptation without requiring a completely separate system for each region.

Inventive Principle:

Principle #3Local quality

Solution Approach 2:

The patent introduces dynamic adaptability through coatings that can change their optical or thermal properties in response to environmental conditions. The spatially adjustable coating system allows certain layers to be modified or activated based on real-time environmental factors such as lighting conditions, temperature, or background characteristics.

Inventive Principle:

Principle #15Dynamics

3Reliability

If multiple functional layers are deposited, then comprehensive camouflage in multiple spectral ranges is achieved, but the manufacturing process becomes more complex

Engineering Contradiction:

Improvecamouflage effectiveness in multiple regimesVSAvoidease of depositing multiple layers

Core Design Contradiction:

ReliabilityVSEase of manufacture

Solution Approach 1:

The patent merges multiple functional layers (adhesive, infrared-reflective, visible-light-absorbing) into an integrated coating system that can be applied as a unified structure. The layers are combined in a single manufacturing process sequence, reducing the complexity of handling and assembling separate components while maintaining the comprehensive camouflage effectiveness across multiple spectral ranges.

Inventive Principle:

Principle #5Merging (Combining)

AI summary

Camouflage coating systems, apparatuses, and methods described herein may include a coating deposited and bonded to a region of an external surface of an object to be camouflaged. The coating may include a plurality of stacked material arrangements deposited and bonded sequentially onto the region of the external surface and arranged to define a laterally distributed plurality of independent camouflage profiles. The coating may be configured to adjust coating emissivity at visual and IR wavelengths and to block or adjust infrared (IR) emitted by the object, thereby concealing the region of the external surface of the object from detection by a detection method in the visual, infrared, and electromagnetic regimes.
