Firearm Sight Mount Magnetic Locking Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sight mounts for firearms with high or very high trajectories are prone to slippage, misalignment, and difficulty in quick and secure adjustment, especially under stressful conditions, leading to inaccurate shooting due to complex range settings and sensitivity to external influences.
Innovation Solution
A sight mount with a base module and a pivotally mounted trajectory module, featuring an actuator for dialing shooting distances, a lock lever for secure positioning, and a graduated trajectory portion with recesses for precise adjustments, allowing for easy reading of distances from behind and accommodating spin-drift compensation with a curved design.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a locking mechanism with a locking knob is used to secure the sight mount at various distances, then the sight mount can be adjusted to different shooting distances, but the locking mechanism may slip out of position or wear over time, causing unintentional movement and misalignment
Solution Approach 1:
The patent replaces the traditional mechanical locking knob system with a magnetic field-based locking mechanism. The magnetic field is generated by a permanent magnet arranged in the trajectory module, which interacts with a ferromagnetic material in the base module to provide secure positioning at various shooting distances without the need for mechanical knobs that can wear or slip.
Solution Approach 2:
The patent changes the locking mechanism from mechanical (friction-based) to magnetic (field-based). This parameter change in the locking principle eliminates wear and slippage issues inherent in mechanical systems while maintaining the ability to securely hold multiple position settings.
2Reliability
If a complex locking mechanism is used to prevent slippage, then position stability improves, but the device complexity increases and quick adjustment becomes difficult
Solution Approach 1:
The patent eliminates complex mechanical locking components (knobs, notches, springs) by substituting them with a magnetic field-based system. The permanent magnet and ferromagnetic material combination provides inherent positioning and locking without requiring complex mechanical structures, thus simplifying the overall device while maintaining reliability.
3Measurement precision
If the sight mount is designed with precise adjustment capabilities for various distances, then measurement precision improves, but the ease of operation decreases due to the need for careful handling and reading
Solution Approach 1:
The magnetic locking system allows the trajectory module to be freely adjusted to the desired position and then automatically locked by the magnetic field, eliminating the need for careful manual handling and reading of complex mechanical indicators. This provides both precise positioning and ease of operation.
Solution Approach 2:
The magnetic field-based locking mechanism is self-actuating - when the trajectory module is moved to a desired position, the magnetic field automatically engages the ferromagnetic material to lock it in place, without requiring additional user actions like turning knobs or pressing buttons. This enables quick and precise adjustment simultaneously.
