Solution Overview

Problem

Modern gunner optics in military vehicles are vulnerable to ballistic threats due to their sensitive optical paths and complex stabilization systems, making them prone to failure from a single hit, and existing protective measures either leave them unprotected or non-functional.

Innovation Solution

A partially transparent protective element, such as bulletproof glass, is integrated into the gunner optics housing, allowing it to be transferred between protective and rest positions to safeguard the optics while maintaining functionality, with the ability to automatically deploy protection upon threat detection.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If protective elements completely close off the gunner optics, then the optics are protected from ballistic threats, but the line of sight is blocked and the optics become inoperable

Engineering Contradiction:
Improveprotection from ballistic threatsVSAvoidline of sight functionality
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The protective element is designed to be movable between a protective position (blocking the opening) and a rest position (allowing line of sight). This dynamic configuration allows the system to switch between protection mode and operational mode, resolving the contradiction between needing protection and needing functionality.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The protective element includes a transparent area that is segmented from the rest of the housing structure. This transparent segment allows light to pass through while the rest of the protective element provides ballistic protection, enabling both protection and optical functionality simultaneously.

Inventive Principle:
Principle #1Segmentation

2Reliability

If the housing is designed to be protected against ballistic impacts, then the gunner optics are protected, but the opening required for line of sight creates a vulnerability

Engineering Contradiction:
Improveprotection against ballistic impactsVSAvoidvulnerability at opening
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The transparent protective element acts as an intermediary between the opening and the external environment. It allows optical energy to pass through while providing ballistic protection, effectively mediating between the need for an open line of sight and the need for protection against ballistic threats.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Ease of operation

If a transparent protective element is used to maintain line of sight, then the optics remain functional, but the transparent area is vulnerable to ballistic impacts

Engineering Contradiction:
Improveoptical functionalityVSAvoidresistance to ballistic impacts
Core Design Contradiction:
Ease of operationVSStrength

Solution Approach 1:

The protective element is made from composite materials that combine transparency with ballistic resistance. This allows the element to simultaneously provide optical functionality and protection against ballistic impacts, resolving the contradiction between maintaining line of sight and withstanding ballistic threats.

Inventive Principle:
Principle #40Composite materials

AI summary

The invention relates to a gunner's sight having a housing, wherein the housing has at least one opening. The housing therefore is not arranged completely around the gunner's sight. At least one sight is arranged in the housing and its line of sight leads out from the opening. Also provided is at least one protection element which is at least partially transparent. The protection element can therefore constitute protection for the gunner's sight and can, nevertheless, guarantee the continued functioning of the gunner's sight as a result of the transparency of the protection element.
