Dual-Side Firearm Selector Lever Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current firearm control devices are inconvenient for left-handed users as the fire selector control is typically positioned only on the left side of the lower receiver, catering primarily to right-handed operators.
Innovation Solution
A fire selector control device designed to be operable from either side of the firearm, featuring a selector body that extends between both sides of the lower receiver, with levers accessible from each side to switch the firing mechanism between multiple modes of operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the fire selector control is positioned only on the left side of the lower receiver, then it is convenient for right-handed operators, but it becomes inconvenient for left-handed users
Solution Approach 1:
The patent applies asymmetry by providing levers on both sides of the lower receiver, creating a symmetric dual-sided control system that adapts to different user preferences and handedness, thereby resolving the contradiction between optimizing for right-handed operators and accommodating left-handed users
Solution Approach 2:
The fire selector control device is designed with universal accessibility by incorporating levers on both the left and right sides of the lower receiver, allowing the same device to serve both right-handed and left-handed operators effectively, thus achieving multi-functionality and broad adaptability
2Ease of operation
If the selector body extends between both sides of the lower receiver, then accessibility is improved for both sides, but the device complexity increases
Solution Approach 1:
The patent merges the control functions into a single selector body that extends across both sides of the lower receiver, integrating multiple levers and switching mechanisms into one unified structure. This combining approach improves accessibility from both sides while managing complexity through functional integration rather than separate independent systems

AI summary
A fire selector control device for a firearm with a lower receiver that is operable from either side of the firearm. The device includes a selector body designed to fit within the lower receiver and extend between one side of the lower receiver and an opposite side of the lower receiver. The selector body is designed to engage a firing mechanism within the firearm and switch the firing mechanism to any one of a plurality of firing modes. First and second levers are attached to opposite ends of the body to move the body to any one of the plurality of firing options. The first lever is accessible from the exterior of the right side of the lower receiver and the second lever is accessible from the exterior of the left side of the lower receiver.
