Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional firearm training is dangerous, expensive, and limited to specific areas, as it requires live ammunition and shooting ranges.
Innovation Solution
A slide for automatic pistols that incorporates a housing with a laser, printed circuit board, and power source, allowing the pistol to simulate firing without live ammunition by using a striker mechanism to activate the laser upon trigger pull, providing a safe and cost-effective training solution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional firearm training using live ammunition is used, then training realism is improved, but safety and cost are worsened
Solution Approach 1:
The patent creates a realistic copy of the firearm operation experience by using a laser module to simulate the muzzle flash and trajectory of live ammunition without the harmful effects. The laser trainer cartridge replicates the visual and operational aspects of real gunfire while eliminating safety risks and costs associated with actual ammunition.
Solution Approach 2:
The patent replaces the mechanical system of live ammunition firing with an optical system. Instead of using actual bullets and gunpowder, the invention uses a laser module activated by the firearm's firing mechanism to produce a visible laser beam that simulates the trajectory and impact point, substituting dangerous mechanical ballistics with safe optical visualization.
2Measurement precision
If live ammunition training is performed, then training accuracy is improved, but accessibility and cost are worsened
Solution Approach 1:
The patent makes the training system universal by adapting it to work with multiple types of firearms. The laser trainer cartridge can be installed in various pistol models (including Glock, SIG Sauer, and Smith & Wesson) by replacing the standard striker, allowing the same training mechanism to function across different firearm platforms without requiring proprietary ammunition or specialized equipment.
Solution Approach 2:
The laser module creates an accurate visual copy of the bullet trajectory, allowing users to see the exact path and impact point of the simulated shot. This optical copying mechanism provides precise training feedback without requiring actual ammunition, enabling accurate training anywhere the firearm can be safely discharged.
3Object-affected harmful factors
If a laser module is integrated into the slide, then training safety is improved, but device complexity is worsened
Solution Approach 1:
The patent merges the laser module with the existing slide assembly of the firearm. The housing is integrated into the slide, and the laser module is positioned to align with the barrel axis. This combining approach incorporates the safety-enhancing laser technology into the familiar slide structure without requiring a completely new design, thereby limiting the increase in complexity.
Solution Approach 2:
The striker serves as an intermediary mechanism that activates the laser module through the existing trigger mechanism. When the trigger is pulled, the striker moves backward and activates the laser module, which then emits the laser beam. This intermediary approach allows the laser to be activated by the normal firing sequence without requiring separate controls or complex activation systems.
4Ease of operation
If the striker mechanism is used to activate the laser, then operational simplicity is improved, but precision of laser activation timing is worsened
Solution Approach 1:
The patent replaces the purely mechanical striker activation with an optical detection system. A light sensor detects when the laser module is properly positioned and activated, providing precise timing feedback. This substitution of mechanical sensing with optical sensing improves the precision of laser activation timing while maintaining the simplicity of trigger-based operation.
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
Enables safe, inexpensive, and versatile firearm training anywhere, allowing users to practice targeting with a fully-loaded magazine and normal gun weight, while the slide can be adapted for various pistol calibers and includes a trigger reset assembly for realistic simulation.
Implementation Method 1
This creates tension (preferably by expanding a spring) to move the striker forward when the firing pin disengages from the striker
Implementation Method 2
This causes the laser to emit light for a short duration, such as about 0.1 seconds
Data Source
AI summary
A slide for an automatic pistol includes a cavity, a housing in the cavity, a laser module at least partially received in the housing, a power source, circuitry, and a striker. The slide has a first mode in which it emits laser light and a second mode in which it does not emit laser light. The striker has a first position in which it does not cause the laser module to emit laser light. When the pistol's trigger is pulled, the pistol's firing pin contacts the striker and moves the striker backwards from the first position to a biased position. When the firing pin moves out of contact with the striker, the striker moves forward to a second position and causes the circuitry to transmit power from the power source to the laser module, which causes the laser module to emit laser light.
