Firearm Unjamming Multitool for Broken Rims and Bolt Over-Ride
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Firearms can jam due to issues such as broken rims, case head separations, and bolt over-ride feeds, which are difficult to resolve in the field without specialized tools.
Innovation Solution
A multitool with a housing, extractor assembly, bolt over-ride claw, and collapsible range rod that can be deployed to address these jams, including an extractor tip for separated cases and a range rod for ejection, all integrated into a single handle for easy use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple separate tools are used to address different jam types, then each tool can be specialized for its specific function, but the overall device complexity increases and portability decreases
Solution Approach 1:
The patent combines multiple separate unjamming tools ( extractor for broken rims, range rod for case head separation, and bolt over-ride tool for bolt over-ride feeds) into a single integrated multitool device. This merging approach allows all necessary unjamming functions to be performed with one tool, reducing the number of separate tools required while maintaining specialized functionality for each jam type.
Solution Approach 2:
The multitool is designed with universal applicability to handle multiple types of firearm jams through different operational components. The extractor assembly can address broken rim situations, the range rod can remove case head separations, and the bolt over-ride tool can clear bolt over-ride feeds, making a single device capable of performing multiple specialized functions.
2Adaptability or versatility
If multiple separate tools are carried for different jam situations, then each tool remains simple and lightweight, but the total weight and bulk increase
Solution Approach 1:
By merging multiple lightweight tools into a single integrated multitool, the overall weight is reduced compared to carrying separate extractor, range rod, and bolt over-ride tools. The combined device maintains the necessary functionality for all jam types while eliminating the cumulative weight of multiple separate tools.
Solution Approach 2:
The multitool provides universal coverage for multiple jam types within a single lightweight device. Instead of requiring separate tools for broken rim extraction, case head separation, and bolt over-ride clearance, the multi-functional design delivers all these capabilities in one compact unit.
3Ease of operation
If a single tool must handle multiple jam types, then portability is improved, but the tool complexity and operational difficulty increase
Solution Approach 1:
The multitool is segmented into distinct operational components (extractor assembly, range rod, bolt over-ride tool) that can be independently activated. Each component is designed to address a specific jam type, allowing the user to select and deploy only the necessary function, thereby reducing operational complexity despite the multi-functional capability.
Solution Approach 2:
The tool incorporates movable and adjustable components that can be dynamically configured for different operations. The extractor assembly can be positioned and angled for broken rim extraction, the range rod can be extended for case head separation, and the bolt over-ride tool can be deployed for bolt over-ride feeds, allowing adaptive functionality without permanent complexity.
4Reliability
If specialized tools are used for each jam type, then the unjamming process is reliable and effective, but the time to locate and deploy the correct tool increases
Solution Approach 1:
The multitool provides universal coverage for all three primary jam types (broken rim extraction, case head separation, and bolt over-ride feeds) within a single device. This eliminates the time required to locate, access, and deploy separate specialized tools, while maintaining the reliability and effectiveness of each unjamming function through dedicated operational components.

AI summary
An unjamming multitool for use with a firearm, including a housing having opposing parallel side plates joined at an edge and having a first end and an opposing second end, and defining a cavity therebetween. A first pivot post and a second pivot post are carried at the first and second ends of the housing. An extractor assembly is pivotally coupled to the first end of the housing by the first pivot post and movable between a stored position adjacent the housing and a deployed position wherein the extractor assembly is pivoted outwardly from the housing about the first pivot post to a stop. A bolt over-ride claw coupled to the opposing second end of the housing by the second pivot post, and movable between a stored position generally within the cavity of the housing and a deployed position pivoted outwardly from the cavity to a 90 degree stop. A collapsible range rod movable between a stored position against one of the opposing parallel side plates and a deployed position extending from the one of the opposing parallel side plates.
