Solution Overview

Problem

Existing weapon systems on vehicles face challenges in achieving complete 4π steradian coverage due to obscured sightlines caused by vehicle components, making it impractical to use multiple gimballed apertures for full coverage.

Innovation Solution

A control system that alters the vehicle's configuration to maintain a clear line-of-sight to the target, using a directed-energy weapon with gimballed apertures and overriding vehicle commands to ensure continuous engagement without obscuration, thereby increasing coverage and preventing damage to the vehicle.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Area of stationary object

If multiple gimballed apertures are used to provide full 4π steradian coverage, then coverage is improved, but device complexity, cost, and weight become impractical

Engineering Contradiction:
Improvecoverage areaVSAvoidnumber of gimballed apertures
Core Design Contradiction:
Area of stationary objectVSDevice complexity

Solution Approach 1:

The patent applies the Dynamics principle by making the vehicle itself movable rather than making multiple weapon apertures movable. The control system dynamically adjusts the vehicle's configuration (attitude, position, or shape) in response to detected obscuration, allowing a single static aperture to achieve full 4π steradian coverage by leveraging the vehicle's dynamic reconfiguration capability instead of requiring multiple gimballed apertures.

Inventive Principle:
Principle #15Dynamics

2Reliability

If the vehicle configuration is altered to maintain clear line-of-sight, then engagement reliability is improved, but vehicle operation may be disrupted

Engineering Contradiction:
Improveengagement reliabilityVSAvoidvehicle operation
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The patent implements the Feedback principle through a control system that continuously monitors whether vehicle components obscure the aperture's line-of-sight to the target. When obscuration is detected, the control system automatically triggers a vehicle configuration alteration to restore clear line-of-sight. This closed-loop feedback mechanism ensures reliable target engagement while minimizing manual intervention, as the system autonomously manages the trade-off between engagement reliability and vehicle operation.

Inventive Principle:
Principle #23Feedback

3Device complexity

If a single aperture is used instead of multiple gimballed apertures, then device complexity is reduced, but coverage area is limited

Engineering Contradiction:
Improvenumber of aperturesVSAvoidcoverage area
Core Design Contradiction:
Device complexityVSArea of stationary object

Solution Approach 1:

The patent applies the Another dimension principle by transitioning from a two-dimensional solution (multiple apertures rotating in different directions) to a three-dimensional solution (vehicle reconfiguration in attitude, position, and/or shape). By utilizing the additional dimension of vehicle configuration space, a single aperture can achieve full 4π steradian coverage as the vehicle dynamically repositions itself relative to the target, eliminating the need for complex multi-aperture gimbal systems.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)
