Scope Mount with Integrated Level Vial for Rifle Cant Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing solutions for maintaining rifle orientation during long-range shooting are prone to accidental displacement, require complex setup, and necessitate the shooter to lift their head to verify plumb orientation, compromising accuracy and robustness.
Innovation Solution
A scope-mounting fixture with a non-removable level-indicating element, such as a bubble vial, integrated into the socket of a picatinny rail, allowing visual feedback on rifle cant from a conventional shooting position, ensuring the level-indicating element is always aligned with the rifle's bore centerline, thus maintaining proper orientation without additional calibration tools.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a level-indicating element is mounted on a transversely-protruding lever element, then the shooter can see the level indicator, but the lever element is subject to damage from bumping into foreign objects and can be knocked out of plumb orientation
Solution Approach 1:
The level-indicating element is nested within a cavity in the scope-mounting fixture base, protected by a recessed wall. The indicator is viewable through an opening in the base, allowing the shooter to see the plumb orientation while the indicator remains protected inside the fixture structure, eliminating the need for a protruding lever element.
2Ease of operation
If a level-indicator is mounted on a scope ring cap, then the level feedback is provided, but great care must be taken during installation as the cap can be tightened unevenly and pulled out of plumb
Solution Approach 1:
The level-indicating element is merged into the scope-mounting fixture base as an integrated, non-removable component. The fixture base and level indicator are manufactured as a single unit or permanently assembled together, eliminating the need for separate installation of a cap-mounted indicator and ensuring the indicator maintains its plumb orientation regardless of tightening variations.
3Ease of operation
If a level-indicator is mounted directly to a rifle scope, then the level feedback is provided, but another level is required on the bolt rails and the cross hair must be plumbed to a vertical plumb line, requiring the shooter to lift their head from the conventional shooting position
Solution Approach 1:
The scope-mounting fixture base is designed with the level-indicating element pre-integrated and pre-oriented to indicate when the rifle bore centerline is in the desired vertical plane. The fixture automatically provides the plumb reference without requiring the shooter to use separate leveling tools or adjust cross hairs, allowing direct observation from the conventional cheek-down shooting position.
4Ease of operation
If the level-indicating element is positioned at an information-broadcast location visible from cheek-down position, then the shooter can maintain proper orientation without lifting their head, but the element must be precisely positioned between the scope optical axis and barrel centerline
Solution Approach 1:
The level-indicating element is pre-positioned and pre-oriented during manufacture of the scope-mounting fixture base, with its reference marking aligned to indicate the desired vertical plane relative to the rifle bore centerline. This preliminary positioning ensures that when the fixture is installed on the rifle, the level indicator is automatically in the correct location and orientation without requiring field adjustment or complex alignment procedures.
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 provides a robust and simple setup for maintaining rifle orientation, allowing shooters to maintain accuracy by ensuring the rifle remains plumb and level without needing to lift their head, enhancing shooting precision and reducing the risk of accidental misalignment.
Implementation Method 1
A scope mount for a rifle includes a level-vial incorporated as a non-removable element of the mount
Data Source
AI summary
A fixture structured to attach a scope to a rifle. The fixture includes a level-vial that is visible by a shooter who is substantially at a conventional horizontal shooting position. In such position, the bubble element of the level-vial is disposed below the scope, and at a location that is intersected by a vertical plane containing the centerline of the rifle barrel.
