Striker Firearm Trigger Sear Block Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing firearms lack improved mechanical function, specifically in trigger and slide stop mechanisms, with no elimination of trigger bars, release levers, and recoil springs, leading to complexity and safety concerns during field stripping.
Innovation Solution
A striker style firearm design that eliminates the trigger bar by direct contact between the trigger and sear block, uses a recoil spring to hold the slide stop in place, and incorporates a reset plunger for efficient operation and safety, allowing field stripping with the trigger in place and enhanced safety features.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a trigger bar is used in the firearm mechanism, then the trigger can be actuated, but the device complexity increases and safety concerns arise during field stripping
Solution Approach 1:
The patent eliminates the trigger bar from the mechanism, directly connecting the trigger to the sear block. This extraction of the intermediate component simplifies the overall mechanism while maintaining trigger actuation functionality, directly resolving the contradiction between ease of operation and device complexity
Solution Approach 2:
The trigger is made to contact the sear block directly, merging previously separate functional elements (trigger bar and sear block connection) into a single integrated interaction. This reduces the number of parts and simplifies the mechanical pathway from trigger to striker release
2Ease of repair
If traditional firearm mechanisms are used, then complete functionality is achieved, but field stripping requires trigger disassembly which creates safety hazards
Solution Approach 1:
By removing the trigger bar, the patent enables the trigger to remain installed in the firearm while allowing complete field stripping of other components. The simplified mechanism permits the trigger to stay in place without interfering with disassembly of the slide, barrel, and other parts, eliminating the safety hazard of unintended firing during field stripping
Solution Approach 2:
The mechanism is segmented such that the trigger assembly becomes independent from the slide and barrel components. This segmentation allows the trigger to remain mounted on the frame while other components are stripped for cleaning or maintenance, improving ease of repair without creating safety hazards
3Reliability
If multiple springs are used in the mechanism, then various functions are achieved, but the quantity of parts increases
Solution Approach 1:
The recoil spring serves multiple functions: it returns the slide to forward position after firing, compresses the sear block spring to enable striker release, and generally maintains tension throughout the mechanism. This multi-functionality reduces the number of separate springs needed while maintaining reliable mechanism function
Solution Approach 2:
The patent combines the functions of multiple springs into a single recoil spring system that coordinates slide movement, striker reset, and sear block actuation. By merging these spring functions, the quantity of springs is reduced while maintaining all necessary mechanical functions
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
This design reduces parts and tolerances, enhances safety by preventing unintended firing during field stripping, and allows for faster disassembly and reassembly, with a tunable trigger pull force through the combination of trigger and sear block springs.
Implementation Method 1
A striker then moves rearward with the slide under operation of the recoil spring and then returns forward
Implementation Method 2
The trigger has a release lever which is allowed to rotate relative to the rest of the trigger when the striker is reset and the sear block moves the release lever to the rotated position. The release lever rotates back to the ready position as the trigger is released
Implementation Method 3
The trigger has a release lever which is allowed to rotate relative to the rest of the trigger when the striker is reset and the sear block moves the release lever to the rotated position

AI summary
A firearm is provided according to the present invention. The firearm can be a striker style firearm having a slide. A trigger contacts a sear block at the front of the striker to fire the firearm. The striker then moves rearward with the slide under operation of the recoil spring and then returns forward. A reset plunger engages the striker during the second part of this process to reset the striker. The trigger has a release lever which is allowed to rotate relative to the rest of the trigger when the striker is reset and the sear block moves the release lever to the rotated position. The release lever rotates back to the ready position as the trigger is released. A slide stop is also provided that is held in place under operation of the recoil spring.
