Centered Windage Wheel Firearm Sight
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing firearm sights are complicated by environmental factors like wind, which cause bullet deviation, and adjustable sights can be inadvertently adjusted due to their additional mechanisms, leading to improper aiming.
Innovation Solution
A sight system with a centered windage wheel mechanism, featuring a bifurcated sight structure and a threaded wheel member that securely positions the sight housing, preventing accidental adjustments and ensuring precise alignment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If adjustable sights with side knobs and mechanisms are used to account for wind drift, then windage adjustment capability is improved, but device complexity increases and reliability decreases due to inadvertent contact
Solution Approach 1:
The patent moves the windage adjustment mechanism from the horizontal plane (side knobs) to the vertical plane (top-mounted wheel), allowing adjustment without lateral protrusions. This dimensional change eliminates the need for side knobs while maintaining full windage adjustment capability, directly resolving the contradiction between adaptability and device complexity.
Solution Approach 2:
Instead of providing adjustment mechanisms that protrude outward (side knobs), the patent inverts the approach by integrating the adjustment wheel into the top surface of the sight assembly. This inversion allows the adjustment mechanism to be accessed from above rather than from the sides, reducing protrusions and improving reliability against inadvertent contact.
2Adaptability or versatility
If adjustable sights with side knobs are used for windage adjustment, then windage adjustment capability is improved, but reliability worsens due to inadvertent contact distorting aiming point
Solution Approach 1:
By relocating the adjustment mechanism to the vertical dimension (top-mounted wheel), the patent eliminates lateral protrusions that could be accidentally contacted. This dimensional relocation maintains full adjustment capability while preventing inadvertent contact, directly improving reliability without sacrificing adaptability.
3Ease of manufacture
If traditional front and rear sight alignment is used, then manufacturing simplicity is maintained, but measurement precision worsens due to alignment errors causing bullet deviation
Solution Approach 1:
The patent incorporates preliminary action by providing pre-milled reference surfaces and precisely positioned adjustment mechanisms during manufacturing. The top-mounted wheel is positioned at a predetermined location with reference to the sight axis, and the housing includes corresponding reference surfaces, ensuring accurate alignment is achieved through careful initial setup rather than field adjustment alone.
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 allows for precise windage adjustment and zeroing of sights, reducing bullet deviation due to environmental factors while minimizing the risk of unintentional adjustments, thereby improving aiming accuracy.
Implementation Method 1
A threaded support member extends transversely between the first side portion and the second side portion... The wheel member is threadably received on the threaded support member

AI summary
A firearm sight including a base coupled to a firearm receiver. The base includes a body having opposed side defining a void therebetween. A sight housing having an end coupled to the base and an opposing end carrying a sight structure. The end coupled to the base is bifurcated with spaced apart furcated portions defining a central gap therebetween. A threaded support member extends transversely between the opposed side portions and concurrently through apertures formed through the furcated portions. A wheel member has a threaded bore and is received on the threaded support member between the furcated portions within the central gap. Rotation of the wheel member moves the sight housing laterally between the opposed sides of the base.
