Solution Overview

Problem

Existing infrared vision systems for soldiers are heavy, power-hungry, costly, and difficult to manage, often requiring multiple components that increase weight, power consumption, and logistical footprint, and are typically helmet-mounted, posing a risk of neck injury.

Innovation Solution

An infrared vision system integrated into a headpiece with a body module, featuring a see-through color display and short-wave infrared sensors, cameras, and diodes, providing augmented visual information without the need for helmet mounting, integrating power and processing components to reduce weight and improve efficiency.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional infrared vision systems are implemented with multiple separate components, then infrared detection capability is achieved, but weight and power consumption increase significantly

Engineering Contradiction:
Improveinfrared detection capabilityVSAvoidsystem weight
Core Design Contradiction:
ReliabilityVSWeight of moving object

Solution Approach 1:

The patent combines multiple separate infrared detection components into a single integrated headpiece device. The headpiece integrates SWIR sensors, visible light cameras, laser detectors, and processing units into one unified structure, eliminating the need for soldiers to carry multiple separate vision systems. This merging directly reduces weight while maintaining comprehensive infrared detection capability.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The headpiece is designed as a multi-functional device that performs infrared detection, visible light imaging, laser designation detection, and target acquisition simultaneously. By making the headpiece universal rather than specialized for a single function, the system eliminates redundant components and reduces overall weight while achieving multiple detection goals in one device.

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

2Reliability

If multiple separate vision components are used, then comprehensive detection coverage is achieved, but the number of components and logistical footprint increase

Engineering Contradiction:
Improvedetection coverageVSAvoidnumber of components
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

Multiple detection functions (SWIR imaging, visible light imaging, laser detection) are merged into a single headpiece unit with integrated sensors and processing. This consolidation reduces the number of separate components from multiple discrete devices to one unified system, simplifying logistics while maintaining comprehensive detection coverage across different spectral ranges.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The headpiece is designed as a universal platform that handles various detection tasks through integrated multi-functional sensors. Rather than requiring separate specialized devices for SWIR, visible light, and laser detection, the universal headpiece performs all functions through its integrated sensor array and processing unit.

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

3Reliability

If individual power sources are provided for each vision component, then each component operates independently, but overall power consumption and battery requirements increase

Engineering Contradiction:
Improvecomponent independenceVSAvoidpower consumption
Core Design Contradiction:
ReliabilityVSUse of energy by moving object

Solution Approach 1:

Multiple power sources required for separate components are merged into a single battery unit that powers the entire integrated headpiece system. This consolidation reduces total power consumption by eliminating redundant power management circuits and reducing overall energy requirements, while still providing independent operation capability for each sensor module through shared power distribution.

Inventive Principle:
Principle #5Merging (Combining)

4Stability of the object's composition

If helmet-mounted vision systems are used, then stable mounting is achieved, but risk of neck injury increases

Engineering Contradiction:
Improvemounting stabilityVSAvoidneck injury risk
Core Design Contradiction:
Stability of the object's compositionVSObject-affected harmful factors

Solution Approach 1:

The vision system is extracted from the helmet mounting structure and repositioned to rest on the soldier's head like eyeglasses. This extraction removes the harmful helmet-mounted configuration while preserving the stability needed for effective operation, thereby eliminating neck injury risk associated with heavy helmet equipment.

Inventive Principle:
Principle #2Taking out (Extraction)
