Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing ceramic armor tiles mounted externally on vehicles and structures suffer from low survivability, increased silhouette and dimensions, reduced maneuverability, and vulnerability to spall damage, leading to a preference for metal armor despite weight deficiencies.

Innovation Solution

Internal ceramic armor tiles are mounted behind the wall of a structure, utilizing a ceramic layer and optional spall-liner, with the wall acting as an external armor layer to minimize kinetic threats and reduce spall dispersion, and can be fixed or detachable using various fastening methods.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If ceramic armor tiles are mounted externally on vehicles and structures, then protection against kinetic threats is improved, but the silhouette and external dimensions are increased

Engineering Contradiction:

Improveprotection against kinetic threatsVSAvoidexternal dimensions

Core Design Contradiction:

StrengthVSVolume of moving object

Solution Approach 1:

The ceramic armor tile is nested within the vehicle structure by mounting it internally on the inner surface of the wall, utilizing the vehicle's own wall as part of the armor system. This eliminates the need for external protruding tiles while maintaining protective functionality.

Inventive Principle:

Principle #7Nested doll (Nesting)

Solution Approach 2:

Instead of mounting the ceramic tile externally on the outer surface of the vehicle wall, the invention inverts the mounting location to the inner surface of the wall, changing the spatial arrangement from external to internal configuration.

Inventive Principle:

Principle #13The other way round (Inversion)

2Strength

If ceramic armor tiles are mounted externally on vehicles and structures, then protection against kinetic threats is improved, but maneuverability is reduced

Engineering Contradiction:

Improveprotection against kinetic threatsVSAvoidmaneuverability

Core Design Contradiction:

StrengthVSEase of operation

Solution Approach 1:

The armor tile is nested within the vehicle's internal space rather than adding external bulk, preserving the vehicle's original dimensions and maneuverability characteristics while providing protective functionality.

Inventive Principle:

Principle #7Nested doll (Nesting)

3Strength

If ceramic armor tiles are mounted externally on vehicles and structures, then protection against kinetic threats is improved, but survivability and multiple hit capability are reduced

Engineering Contradiction:

Improveprotection against kinetic threatsVSAvoidsurvivability

Core Design Contradiction:

StrengthVSReliability

Solution Approach 1:

A spall liner is installed on the outer surface of the ceramic tile to cushion and capture spall fragments before they can cause damage. This pre-positioned protective layer enhances survivability by containing fragmentation from potential impacts.

Inventive Principle:

Principle #11Beforehand cushioning (Prior cushioning)

4Object-affected harmful factors

If a spall-liner is fitted inside a vehicle fitted with external ceramic tile armor, then protection against spall damage is improved, but the complexity of the armor system is increased

Engineering Contradiction:

Improveprotection against spall damageVSAvoidarmor system complexity

Core Design Contradiction:

Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The spall liner functionality is merged with the ceramic tile assembly by positioning the spall liner directly on the outer surface of the tile, creating an integrated protective unit that reduces overall system complexity compared to separate external and internal armor systems.

Inventive Principle:

Principle #5Merging (Combining)
