Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing laser sighting devices for Percussion Actuated Non-Electric (P.A.N.) disrupters obstruct the barrel and cause wear, require removal before use, leading to potential inaccuracies due to triangulation/parallax effects, especially in remote operations where depth perception is limited.
Innovation Solution
A laser sighting device with four laser emitters set in a body that slides onto the barrel, using non-conductive cap screws to secure and activate the emitters, projecting parallel beams through equally spaced apertures to eliminate triangulation/parallax and allow consistent sighting regardless of range distance, without obstructing the bore.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a single laser is secured in a laser sight body affixed to the end of the disrupter barrel, then the laser can be used for sighting, but it obstructs the barrel and causes wear and damage
Solution Approach 1:
The invention divides the laser sighting function into multiple separate laser emitters (first, second, third, and fourth lasers) positioned at different locations around the barrel. This segmentation allows the lasers to project sighting patterns without a single obstructive component blocking the barrel, thereby reducing wear and damage while maintaining sighting accuracy.
2Object-affected harmful factors
If the laser sight is removed from the barrel after target acquisition, then the barrel is no longer obstructed, but the user may inadvertently move the barrel causing the shot to miss
Solution Approach 1:
The multiple laser emitters are pre-positioned around the barrel in fixed locations, establishing parallel sight lines before the shooting action occurs. This preliminary positioning ensures that the sighting reference frame is already established and cannot be inadvertently moved during the critical moment of firing, thereby maintaining shot accuracy without requiring removal of the sight.
3Object-affected harmful factors
If the laser is mounted external to the bore adjacent to the barrel, then the bore is not obstructed, but triangulation/parallax effect occurs reducing accuracy at distances other than the known sighted distance
Solution Approach 1:
The invention uses an asymmetric arrangement of multiple laser emitters positioned at specific locations around the barrel (front, rear, left, right sides) rather than a single symmetric mounting point. This asymmetric multi-point configuration creates multiple parallel reference lines that eliminate triangulation/parallax effects, allowing accurate sighting at various distances without obstructing the bore.
4Measurement precision
If four laser emitters are used to parallel the bore on multiple sides, then triangulation/parallax is eliminated and consistent sighting is achieved at various distances, but the device complexity increases
Solution Approach 1:
The invention merges multiple laser emitter functions into a single integrated laser sight body that surrounds the barrel. By combining the mounting structure and multiple laser emitters into one unified device, the complexity of individually mounting and aligning four separate lasers is reduced, while still achieving the benefit of parallel sight lines that eliminate triangulation/parallax effects.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution provides a consistent laser pattern for accurate targeting at various distances, eliminates the need for removal before use, and prevents barrel obstruction, ensuring accurate shots without wear on the disrupter.
Implementation Method 1
Each of the lasers, when illuminated, projects a beam that is parallel to the bore of the barrel through four equally spaced laser light apertures in the laser sight body
