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.
Innovation Solution
A firearm laser sight alignment system with a reduced number of components, utilizing an alignment pin 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 Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a significant number of components are used to position the laser, then the laser can be adjusted for elevation and windage, but the device complexity increases and manufacturing becomes more difficult
Solution Approach 1:
The patent combines multiple adjustment functions into a single integrated laser module assembly that is directly mounted to the firearm frame. The laser module incorporates both elevation and windage adjustment capabilities within one unit, eliminating the need for separate adjustment mechanisms and reducing overall component count while maintaining full adjustability.
Solution Approach 2:
The laser module is designed as a universal assembly that performs multiple functions: providing the laser beam, enabling elevation adjustment, enabling windage adjustment, and mounting to the firearm frame. This multi-functional design reduces the number of separate components needed compared to prior art that used dedicated separate mechanisms for each function.
2Manufacturing precision
If multiple components with associated tolerances are used, then the laser can be positioned accurately, but alignment issues arise during manufacture and use
Solution Approach 1:
By integrating the laser, adjustment mechanisms, and mounting features into a single module assembly, the patent reduces the number of interfaces between components. This minimizes cumulative tolerance errors and alignment issues that arise when multiple separate parts must be precisely aligned relative to each other, while still achieving the required positioning accuracy.
3Ease of operation
If the laser is mounted externally to the frame, then the laser can be adjusted, but misalignment occurs under rugged use conditions
Solution Approach 1:
The laser module is directly integrated with the mounting features that attach to the firearm frame, creating a unified assembly. This integrated approach ensures that the laser remains properly aligned relative to the firearm's reference plane even under rugged use conditions, eliminating the misalignment problems that occur with externally mounted lasers that can move independently.
4Ease of operation
If a resilient coupling is used for angular movement, then alignment can be adjusted, but longitudinal or axial displacement is prevented
Solution Approach 1:
The resilient coupling is designed with specific local properties: it provides angular movement capability in the necessary directions for alignment adjustment while maintaining rigid connection in the longitudinal and axial directions. This selective flexibility allows angular adjustment while preventing unwanted displacement, achieving both adjustability and stability.
