Movable Sight Level for Firearm with Hinge Connector
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing firearm sighting systems lack a practical and non-obstructive method for indicating the vertical plane alignment, often requiring complex and expensive in-scope or out-of-sight level devices that can be difficult to install and may be prone to physical damage.
Innovation Solution
A movable leveling device with a gravity-driven bubble level or electronic indicators that can be easily attached to the scope with a hinge connector and adjustable screws, allowing for two working positions to enhance alignment accuracy and reduce the risk of physical damage, while also enabling easy addition of additional accessories.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If in-scope level indicators are added to the sighting apparatus, then alignment accuracy is improved, but device complexity and cost increase, and the original telescopic viewing design is detracted from
Solution Approach 1:
The level indicator is extracted from the scope's optical path and placed outside the viewing area. The sight level assembly is mounted to the sight housing or firearm body at a location that does not interfere with the telescopic viewing, thereby maintaining alignment indication functionality while preserving the original sighting design integrity
Solution Approach 2:
A separate sight level assembly acts as an intermediary device between the shooter and the target. It provides alignment indication through a distinct optical path or visual reference system that complements rather than complicates the primary scope's design
2Measurement precision
If out-of-sight level indicators are added to the sighting apparatus, then alignment accuracy is improved, but the indicators are located in poor viewing positions and are physically unprotected from damage
Solution Approach 1:
The sight level assembly is designed as a separate, detachable unit that can be independently mounted and positioned. This segmentation allows the level indicator to be placed in a location that is both visible to the operator and protected from damage, rather than being integrated into vulnerable positions
Solution Approach 2:
The sight level assembly includes a protective structure or mounting configuration that shields the level indicator from physical damage before exposure to harmful conditions. The design anticipates potential damage risks and incorporates protection measures in advance
3Adaptability or versatility
If strap and fastener mounting methods are used for leveling devices, then installation flexibility is improved, but precise alignment is difficult to maintain during fastening
Solution Approach 1:
The mounting system replaces flexible strap and fastener connections with a rigid or semi-rigid mounting mechanism that incorporates alignment features. This mechanical substitution provides both the flexibility of easy installation and the precision of maintained alignment during the fastening process
