X-Shaped Laser Aiming Mark Projection System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing laser aiming systems struggle to project a clear and adjustable aiming mark on targets with complex backgrounds or shapes, and their reliability is compromised by varying distances between the shooter and the target.
Innovation Solution
A laser aiming system that projects a X-shaped mark formed by two intersecting planar fanned beams with different supplementary angles, allowing for easy alignment and maintaining accuracy over great distances, and accounting for inherent beam drift to compensate for projectile trajectory.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a spot mark is projected on a target, then the aiming mark is simple to generate, but it is difficult to maintain position on colourful targets, moving targets, or targets with visual details
Solution Approach 1:
The aiming mark is segmented into multiple distinct lines (horizontal line, vertical line, and diagonal X lines) rather than a single spot. This segmentation creates a more complex pattern that provides better visual reference points for maintaining position on various target types, resolving the contradiction between simplicity and reliability.
Solution Approach 2:
The patent utilizes different visual characteristics (color, brightness, or contrast) of the laser lines to ensure they stand out against various target backgrounds. By adjusting the visual properties of the projected lines, the system maintains reliability across colourful and visually complex targets while keeping the generation process simple.
2Reliability
If a crosshair is projected as the aiming mark, then the mark provides good visual reference, but it is difficult to adjust and see on objects with rounded shapes or horizontal/vertical features
Solution Approach 1:
The patent introduces asymmetric diagonal lines (X-shaped components) in addition to the traditional symmetric crosshair lines. This asymmetry creates distinctive visual patterns that are easier to distinguish and adjust on rounded or feature-rich targets, while maintaining the visual reference quality of the crosshair structure.
Solution Approach 2:
The patent adds diagonal dimensions to the traditional two-dimensional crosshair by incorporating X-shaped lines at various angles. This dimensional enhancement provides additional reference points that improve adjustability and visibility on targets with rounded shapes or prominent horizontal/vertical features.
3Ease of manufacture
If the laser aiming system is aligned to an expected hit spot at a known distance, then the alignment is simple, but the mark becomes unreliable when the distance changes
Solution Approach 1:
The patent implements a dynamic alignment system where the laser modules can be adjusted and repositioned to account for changing distances. The system adapts to different ranges by modifying the projection parameters and positions of the multiple laser modules, maintaining reliability across varying distances while keeping the initial alignment process simple through standardized mounting configurations.

AI summary
The laser aiming system for projecting a X-shaped aiming beam along an aiming axis, has a first and second laser modules which are adapted to project a first and second planar fanned beams along a first and second axes of projection respectively. The first and second axes of projection extend parallel with, and spaced-apart from each other and from the aiming axis. The first and second planar fanned beams are skewed about the first and second axes of projection respectively, intersecting each other on the aiming axis and forming a X-shaped aiming beam having different supplementary angles.
