Rail Mountable Diopter Sight with Integrated Elevation Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional rail mountable diopter rear sights for close quarters battle and medium to long-range engagements require complex calibration systems with separate tools, which are prone to damage and may not be available in the field, and often have small moving parts that are difficult to adjust under harsh conditions.
Innovation Solution
A rail mountable diopter rear sight design featuring a housing with a pivotably connected drum arm, a rotatably engaged sight drum, and an elevation adjustment screw that threads into the sight drum, allowing for easy adjustment without the need for additional tools, using a spring mechanism for stabilization and click stops for precise calibration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a separate locating screw and tool are used to calibrate drum sights elevation, then calibration precision can be achieved, but device complexity increases and ease of operation deteriorates due to requiring separate tools that may not be available in the field
Solution Approach 1:
The patent combines the elevation calibration function directly into the drum rotation mechanism. The drum sight rotates on a pivot pin that is integral to the housing, eliminating the need for separate locating screws and calibration tools. The drum's rotational movement itself provides the elevation adjustment, merging what were previously separate functions into a single integrated mechanism that maintains precision while improving ease of operation.
2Measurement precision
If complex calibration screw systems with small moving parts are used, then elevation calibration can be achieved, but reliability deteriorates due to susceptibility to damage and improper adjustment under harsh field conditions
Solution Approach 1:
The patent removes the vulnerable small moving parts (locating screws, calibration screws, and associated tools) from the system. Instead, it uses a robust pivot pin that is integral to the housing structure to enable drum rotation. This extraction of fragile components eliminates their susceptibility to damage and improper adjustment while maintaining the necessary elevation calibration functionality through the drum's rotational movement.
3Adaptability or versatility
If multiple separate components are used for drum rotation and elevation calibration, then functional versatility is achieved, but device complexity increases
Solution Approach 1:
The patent merges the drum rotation mechanism and elevation calibration function into a single integrated system. The drum sight rotates on a pivot pin that is integral to the housing, and this rotational movement simultaneously achieves both the mechanical function of drum rotation and the elevation calibration function. This consolidation maintains full sighting system functionality while eliminating the complexity of separate locating screws, calibration screws, and associated tools.
