Handgun Reflex Sight Reducing Parallax via Lowered Electronics
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing handgun reflex sights face accuracy issues due to parallax errors caused by higher mounting positions required to avoid interfering with the slider mechanism, leading to reduced accuracy and potential misalignment during rapid firing.
Innovation Solution
A static mounted handgun sight design with an upper mounting portion for the lens and light projection point, and side mounting portions that locate the electronics compartment below the slider, allowing the sight to be positioned closer to the barrel line, reducing parallax errors and enabling a lower sighting line.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the sight is mounted directly to the slider of the handgun, then the mounting position is low which accurately aligns the line of sight with the line of the barrel reducing parallax errors, but the slider moves during firing requiring the user to reacquire the sighting dot and the mass of the sight interferes with slider operation
Solution Approach 1:
The sight mounting system is segmented into a static mounting portion attached to the handgun frame and a movable portion that accommodates the sight components. This allows the mounting structure to be separated from the moving slider, eliminating interference with slider operation while maintaining accurate sight alignment.
Solution Approach 2:
The sight mounting system is extracted from the moving slider and repositioned to mount statically to the handgun frame. This removes the sight from the moving component, eliminating the need for reacquisition during firing and preventing interference with slider operation.
2Stability of the object's composition
If a static mounted sight is provided that mounts to the frame of the handgun, then the sight is static during shooting, but the higher mounting position raises the sighting line and introduces parallax errors
Solution Approach 1:
The mounting system utilizes the vertical dimension by extending downward from the frame to create clearance space. This allows the sight to be positioned lower than conventional frame-mounted sights while remaining static, thereby reducing parallax errors without sacrificing stability.
Solution Approach 2:
The sight mounting structure is nested within the space created by extending downward from the frame. The mounting portions are positioned to utilize the vertical clearance, allowing the sight to occupy a lower position that reduces parallax while maintaining static stability.
3Ease of manufacture
If the electronics compartment is positioned above the slider, then the sight components are easily accessible, but the sight interferes with the operation of the slider
Solution Approach 1:
The electronics compartment is extracted from the area above the slider and repositioned to the side or below the slider. This removes the source of interference while maintaining accessibility through alternative positioning that does not obstruct slider movement.
Solution Approach 2:
The electronics compartment is repositioned from the vertical space above the slider to the lateral or lower space beside the slider. This dimensional change eliminates interference with slider operation while preserving component accessibility through alternative spatial arrangement.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution effectively reduces parallax errors and improves accuracy by positioning the sight's components to minimize interference with the slider mechanism, allowing for a lower sighting line that aligns more closely with the barrel, enhancing the handgun's accuracy and operational stability.
Implementation Method 1
The light is projected onto a lens and the lens reflects the light spot back to the eye of the firearm user
Implementation Method 2
the lens reflects the light spot back to the eye of the firearm user who, looking through the lens, uses the light spot as a reference for aiming the firearm
Data Source
AI summary
A static reflex sight for a handgun can reduce parallax errors and improve accuracy by locating electronic components of the sight in compartments disposed below the slide of the handgun rather than above. Only the sight lens and light projection point need be located in an upper mounting portion situated above the slide. An electronics compartment connected to the upper mounting portion by a side mounting portion can house an LED, battery and control electronics. An optic fiber conveys light from the LED to the light projection point which projects light onto the lens.
