Trigger Guard Laser Sight with Underlying Extension
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing laser gunsight systems require significant modifications to firearms, are not easily operable in the firing position, and often have fragile or insecure connections, making them impractical for quick and accurate aiming under poor lighting conditions, especially for military and police users.
Innovation Solution
A laser sighting system integrated into the trigger guard of a firearm with a one-piece molded plastic frame, featuring a body with an elongated extension that underlies the lower portion of the trigger guard, a secure switch activation mechanism, and electronic components, allowing for secure and intuitive operation without modifying the firearm or disrupting its internal components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a laser gunsight system is mounted on a firearm using existing designs, then the laser can illuminate the point of aim, but the firearm requires significant modification including wire routing through the frame and mounting modifications
Solution Approach 1:
The laser gunsight system is divided into separate functional components: the laser assembly mounted on the trigger guard, the power supply integrated into the grip, and the switch mechanism positioned for finger actuation. This segmentation allows each component to be optimized independently and installed with minimal firearm modification.
Solution Approach 2:
The trigger guard serves as an intermediary mounting structure that connects the laser assembly to the firearm without requiring frame modifications. The power supply in the grip acts as an intermediary energy source, eliminating the need for external battery packs or complex wiring through the firearm frame.
2Use of energy by moving object
If the power supply is located in the grip with wires running through the frame, then the laser can be powered, but the wires and switch mounting require firearm modification
Solution Approach 1:
The grip structure itself serves dual purposes: it houses the power supply and provides the mounting structure for the switch mechanism. This self-service approach eliminates the need for separate mounting brackets and complex wiring harnesses that would require firearm modification.
3Ease of operation
If the switch is positioned at the back underside of the trigger guard, then the laser can be actuated, but the connection becomes fragile and operation is not intuitive
Solution Approach 1:
The switch mechanism is pre-positioned in a location that is naturally accessible to the trigger finger, eliminating the need for awkward hand positioning or complex actuation sequences. The switch is integrated into the trigger guard structure beforehand, ensuring secure connections before the firearm is assembled.
4Strength
If the laser mounting requires modification of the front of the trigger guard, then the laser can be securely mounted, but the firearm structure must be altered
Solution Approach 1:
The trigger guard is designed to serve multiple functions: it protects the trigger, provides structural support for the firearm, and serves as a mounting platform for the laser assembly and switch mechanism. This multi-functionality eliminates the need for separate mounting brackets or structural modifications.
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 accurate and intuitive laser aiming without modifying the firearm, ensuring secure alignment with the gun barrel and minimizing disruption to the user's grip, thus providing reliable targeting in low-light conditions without the need for professional installation or complex assembly.
Implementation Method 1
a battery-powered laser is used, the laser having been adjusted to illuminate the point of aim of the firearm. When the laser is turned on by the user of the firearm, it shines light in the direction the bullet will travel when the firearm is fired.
