Integrated Laser Sight Alignment Assembly for Rugged Firearms
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing firearm laser sights require a significant number of components, leading to manufacturing complexity and alignment issues, especially under rugged conditions, and prior devices suffer from misalignment due to external mounting assemblies.
Innovation Solution
A firearm laser sight alignment system with a reduced number of components, utilizing a housing with alignment pins to move a laser module relative to the frame, allowing for efficient alignment adjustments without adhesives, and incorporating a resilient coupling for angular movement without longitudinal or axial displacement.

Engineering Contradiction Analysis
1Manufacturing precision
If a significant number of components are used to position and adjust the laser sight, then the laser can be precisely positioned and adjusted, but the manufacturing complexity increases and alignment issues arise
Solution Approach 1:
The patent combines multiple components into an integrated assembly where the laser module is mounted directly within a housing that is part of the firearm structure. The alignment pin is integrated into the housing rather than being a separate adjustable component, reducing the total number of parts while maintaining alignment precision through the direct mounting relationship between the laser module, housing, and alignment pin.
Solution Approach 2:
The alignment pin is pre-positioned within the housing at a predetermined location that establishes the correct alignment relationship between the laser module and the firearm barrel axis. This preliminary positioning eliminates the need for complex adjustable mechanisms during manufacturing, as the alignment is built into the structure itself through the predetermined placement of the alignment pin relative to the laser module mounting surface.
2Ease of operation
If multiple components with associated tolerances are used, then adjustment capability is provided, but alignment issues and manufacturing difficulty increase
Solution Approach 1:
The housing is designed as a single integrated component that incorporates the laser module mounting surface, the alignment pin, and the structural interface to the firearm frame. This merging eliminates the need for multiple separate components with cumulative tolerances, simplifying manufacturing while maintaining alignment adjustment capability through the built-in alignment pin mechanism.
Solution Approach 2:
The alignment pin is designed to self-align the laser module with the firearm barrel axis through its predetermined positioning within the housing. The pin's location is inherently tied to the housing structure, creating a self-aligning system that does not require complex external adjustment mechanisms or multiple coordinated components, thereby easing manufacturing while preserving alignment capability.
3Ease of manufacture
If the laser is mounted externally on the firearm frame, then installation is simplified, but misalignment occurs under rugged use conditions
Solution Approach 1:
The laser module is nested within a housing that is itself integrated into or mounted as part of the firearm frame structure. This nested arrangement provides a protected, stable environment for the laser module while maintaining a compact overall structure. The alignment pin extends from the housing to contact the laser module, providing a reliable mechanical connection that resists misalignment during rugged use while keeping the installation process simple through the modular housing design.

AI summary
The present disclosure relates to a firearm which may include a frame with a first outer wall, and a second outer wall opposite the first outer wall. A laser module may be disposed between the first and second outer walls. An alignment pin may be in communication with the first outer wall and may be configured to move the laser module relative to the frame.
