Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for replacing fire control selectors or selector switches on firearms require extensive disassembly of the firearm, making the process time-consuming and labor-intensive.
Innovation Solution
A method and kit that includes a sear spring and sear deflector block, and a detent deflector button to facilitate the removal and replacement of the selector switch by engaging and disengaging key components, allowing for quicker and more efficient switching between modes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional methods are used to remove and replace selector switches, then the firearm can be maintained and modified, but extensive disassembly of the firearm is required which is time-consuming and labor-intensive
Solution Approach 1:
The tool is divided into distinct functional segments: a handle portion for manual operation, a button portion for depressing the detent, and a selector switch portion for engagement. This segmentation allows each component to perform its specific function independently while working together as an integrated system, enabling rapid selector switch replacement without extensive firearm disassembly
Solution Approach 2:
The tool acts as an intermediary device between the operator and the selector switch retention mechanism. By introducing this intermediate tool with its button portion that can depress the detent, the system enables selector switch removal without requiring direct manual manipulation of the retained components, thereby simplifying the overall process
2Ease of operation
If numerous portions of the firearm are disassembled to remove selector switches, then access to internal components is achieved, but time and effort are significantly increased
Solution Approach 1:
The tool enables the operator to perform the selector switch replacement operation independently without requiring assistance or extensive disassembly of the firearm. The integrated design with the button portion for detent depression and the selector switch portion for engagement allows a single operator to complete the entire replacement process efficiently

AI summary
Disclosed herein is a method and apparatus for replacing a selector switch of lower receiver of a firearm, the method including the steps of: removing an ancillary portion of the selector switch; inserting a sear spring and sear deflector block into the lower receiver such that a hook portion and an end portion of the sear spring engage a sear and a portion of a sear spring to cause the sear and the portion of a sear spring to be disengaged from the selector switch; inserting a detent deflector button into a side of the lower receiver such a spring biased detent is depressed and the selector switch extends from an opposite side of the lower receiver; removing the selector switch; inserting a new selector switch into the opposite side of the lower receiver such that the detent deflector button is dislodged from the side of the lower receiver; removing the sear spring and sear deflector block; and securing the removing the ancillary portion or a new ancillary portion to the new selector switch.
