Adjustable Gun Sight Base With Pre-Calibrated Cam
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional gun sight mounts for firearms do not provide rapid, pre-calibrated adjustments for elevation and trajectory, requiring tools and not being specific to the shooter's weapon and ammunition, which is inadequate for combat or competition scenarios.
Innovation Solution
A vertically adjustable bridge with a pre-calibrated adjustment cam that allows one-handed selection of target ranges, integrated with a mount platform for the gun sight, restricting movement to the projectile trajectory plane, and adaptable to various calibers and barrel lengths through interchangeable cam assemblies.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional ring mounts are used to secure the gun sight, then the mount can be securely attached to the firearm, but rapid tool-free adjustments for elevation and trajectory cannot be achieved
Solution Approach 1:
The mount incorporates a dynamic adjustment mechanism with a movable bridge that can be quickly repositioned along the rail system. This allows the optic to be rapidly adjusted to different elevation and trajectory positions without tools, transforming a static mount into a dynamically adjustable system that responds to changing combat or competition requirements
Solution Approach 2:
The mount is divided into segmented components including the base, rail system, and adjustable bridge sections. This segmentation allows independent adjustment of each component while maintaining overall structural integrity, enabling rapid reconfiguration without affecting the entire mount system
2Measurement precision
If pre-calibrated adjustments are implemented for specific weapons and ammunition, then accurate trajectory correction is achieved, but adaptability to different calibers and barrel lengths is reduced
Solution Approach 1:
The mount system incorporates multiple interchangeable cam assemblies, each pre-calibrated for specific weapon-ammunition combinations. This universal design allows the same base mount to adapt to different calibers and barrel lengths by simply swapping cam assemblies, maintaining trajectory accuracy across various firearm configurations without requiring a completely different mount system
Solution Approach 2:
The system enables parameter changes by allowing users to swap cam assemblies with different calibration parameters. Each cam assembly contains pre-calibrated settings for specific ballistics parameters, and changing the cam assembly changes the calibration parameters to match the new weapon-ammunition combination, achieving both precision and adaptability
3Manufacturing precision
If manual adjustment with small hand tools is used, then fine-tuning of the reticule is possible, but rapid adjustment in combat or competition scenarios cannot be achieved
Solution Approach 1:
The mount incorporates self-adjusting mechanisms including spring-loaded detents and friction-based locking systems that automatically maintain precise reticule alignment during adjustment. The cam assemblies are pre-calibrated to provide self-correcting alignment, eliminating the need for manual fine-tuning with hand tools while maintaining manufacturing precision
Solution Approach 2:
The cam assemblies are pre-calibrated with predetermined adjustment positions for common trajectory corrections. This preliminary action allows shooters to make rapid adjustments by simply selecting the appropriate pre-calibrated position on the cam, without requiring time-consuming manual calculation or fine-tuning during combat or competition scenarios
