Firearm Sighting Device Rotary Actuator Preset Settings
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sighting devices for firearms, particularly handguns, have low ease of use and difficulty in setting different preset visor settings, due to their design limitations which restrict comfortable and feasible solutions within the required dimensions.
Innovation Solution
A sighting device with a rotary actuator and multiple adjustment elements allows for easy and quick selection of various visor settings by rotating the actuator to position adjustment elements on an abutment element, enabling precise height positioning and multiple preset settings, while a second actuator adjusts for daily settings based on lighting or ammunition changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If two individually swivelling visor lever arms with separate adjustment devices are provided, then quick adjustment options are offered, but the device complexity increases and ease of operation decreases
Solution Approach 1:
The adjustment device is segmented into a rotary actuator with multiple adjustment elements distributed at different angular positions. Each adjustment element corresponds to a preset visor setting, allowing the user to select between multiple configurations by simply rotating the actuator to different angular positions, thereby providing versatility without increasing operational complexity
Solution Approach 2:
The rotary actuator enables dynamic selection between multiple preset visor settings through rotation. The adjustment elements are positioned at different angular locations, allowing the visor lever arm to be quickly adjusted between predefined positions by rotating the actuator, combining the benefits of multiple settings with simple operation
2Adaptability or versatility
If multiple adjustment elements are provided on the rotary actuator, then multiple preset visor settings can be made, but the device complexity increases
Solution Approach 1:
The rotary actuator serves multiple functions: it provides the adjustment mechanism itself and simultaneously houses multiple adjustment elements that represent different preset settings. This multi-functional design allows multiple visor configurations to be achieved through a single compact component rather than requiring separate adjustment mechanisms for each setting
Solution Approach 2:
Multiple adjustment elements are nested within the rotary actuator structure. The adjustment elements are distributed around the rotation axis of the rotary actuator, with each element positioned at a specific angular location. This nesting allows multiple settings to be integrated into a single compact component without significantly increasing overall device complexity
3Volume of moving object
If the sighting device is designed for handguns with limited dimensions, then it fits the weapon, but comfortable and feasible adjustment solutions cannot be found
Solution Approach 1:
The adjustment elements are arranged in an angular dimension around the rotary actuator's rotation axis rather than requiring linear space. By distributing adjustment elements at different angular positions (0°, 60°, 120°, 180°, 240°, 300°), the design utilizes rotational space to pack multiple settings into a compact radial footprint, making it suitable for handgun dimensions while maintaining operational feasibility

AI summary
A sighting device (1) for firearms, having: a base (2); a first sighting lever arm (3) pivotable relative to the base (2) about a first pivot axis; a second sighting lever arm (4) pivotable relative to the first sighting lever arm (3) about a second pivot axis extending parallel to the first pivot axis; a notch device (5) fastened on the second sighting lever arm (4); a first adjusting device (6) for adjusting a pivot angle of the first sighting lever arm (3) relative to the base (2); and a second adjusting device (7) for adjusting a pivot angle of the second sighting lever arm (4) relative to the first sighting lever arm (3) and relative to the base (2). The first adjusting device (6) has a rotary adjusting element (20) which is fastened on the first sighting lever arm (3), can be rotated about an axis of rotation extending perpendicular to the first pivot axis and is equipped with a plurality of adjustment elements (13). Each of the adjustment elements (13) has an adjusting tip (28) directed towards a bottom (30) of the base (2) and can be fastenably adjusted relative to the rotary adjusting element (20) such that a distance between the adjusting tip (28) and the rotary adjusting element (20) can be changeably adjusted. A counter-bearing element (18) for interaction with one of the adjusting tips (28) in each case is provided on the bottom (30) of the base (2). With a sighting device of this kind, a plurality of different basic settings of the sighting device for different strike heights can be adopted and can be selected quickly and easily during use.
