Adjustable Trigger Firearm with Laser Shot Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional dry firing practices for pistol training lack feedback on target alignment and recoil management, making it difficult for shooters to improve their skills without the expense and noise of live fire, and existing alternatives like airsoft guns can be distracting and noisy.
Innovation Solution
A training pistol with a grip, trigger, and sighting system that simulates real firearm mechanics, incorporating a feedback system with shot-indicating lasers to provide visual confirmation of trigger take-up and break, allowing for precise training without live ammunition.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If dry firing is used for pistol training, then training can be conducted without ammunition expense and noise, but there is no feedback on target alignment and recoil management
Solution Approach 1:
The patent implements a feedback system using lasers that project onto the target to indicate shot placement accuracy and trigger break timing. This provides real-time visual feedback to the shooter during dry firing, allowing them to see whether their shots are centered on the target and whether they are properly breaking the trigger, thus resolving the information loss problem while maintaining the quiet, ammunition-free benefits of dry firing
Solution Approach 2:
The patent introduces an intermediary system (laser projection system) between the trigger mechanism and the target to provide indirect feedback. The lasers act as mediators that translate the mechanical trigger action into visual information about shot placement and trigger break, enabling feedback without actual projectile discharge
2Loss of information
If air soft guns are used to provide projectile feedback, then hit/miss indication is available, but the BBs create noise and distraction unacceptable for household use
Solution Approach 1:
The patent replaces the mechanical projectile system (air soft guns expelling BBs) with an optical system (lasers). Instead of using physical projectiles to indicate hit/miss, the system uses light projections that activate or change based on trigger action and simulated ball trajectory, providing the same information feedback without the noise and distraction of expelling BBs
Solution Approach 2:
The patent uses lasers as an intermediary to transfer the information function from physical projectiles to light. The lasers mediate between the trigger mechanism and the visual feedback, allowing the system to indicate shot placement and accuracy without requiring actual projectile discharge that creates noise
3Adaptability or versatility
If traditional dry firing is used, then recoil management training is eliminated, but it allows training in many more locations
Solution Approach 1:
The patent creates a copy of the live fire experience by simulating recoil through mechanical means while maintaining the dry firing format. The device replicates the recoil impulse and associated visual feedback that would occur in live fire, allowing shooters to train recoil management in the quiet, location-flexible environment of dry firing without actually discharging ammunition

Function Achieved in This Case
Enables effective dry firing training by providing visual feedback on trigger mechanics and shot placement, enhancing skill development in recoil management and accuracy without the noise and expense of live fire, while being discreet enough for household use.
Implementation Method 1
a laser module positioned in the grip portion and having a longitudinal axis collinear with the longitudinal axis of the barrel, the laser module having a shot indicating laser positioned at the forward end of the laser module and a take-up indicator positioned at the rearward end of the laser module
