Passive Trigger Guard Laser Switch for Limp Wristing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing laser sight power switches on handguns are ineffective when the user engages in 'limp wristing,' where the middle finger does not firmly grasp the grip, and there is a need for adaptable mounting on various gun frames.
Innovation Solution
A flush triggerguard-located switch with flexible or rigid configurations, using impedance detecting or heat sensing devices, that allows passive operation without additional effort or displacement, ensuring the switch is operable by the user's natural finger movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a switch is placed on the handgun grip under the trigger guard, then the laser sight can be switched on during aiming, but the switch fails to function when the user's middle finger does not firmly grasp the grip (limp wristing)
Solution Approach 1:
The switch is positioned on the trigger guard surface where it is automatically activated by the natural resting position of the user's finger, eliminating the need for deliberate switching action. The system serves itself by using the user's existing finger placement during aiming to both trigger the laser and maintain grip control.
Solution Approach 2:
The switch is pre-positioned on the trigger guard surface in a location that will be contacted by the user's finger before aiming begins or as the finger naturally positions itself. This preliminary positioning ensures the laser is activated in advance or automatically when the user assumes the aiming posture, regardless of whether the grip is firm or limp.
2Ease of operation
If a switch is placed on the handgun grip, then the laser sight can be controlled, but it interferes with the user's finger movement or requires additional finger effort
Solution Approach 1:
The laser sight control function is merged with the existing grip operation. The same finger that naturally rests on or near the trigger guard during aiming serves dual purposes: maintaining grip control and activating the laser sight. This consolidation eliminates the need for separate control actions or additional finger movements.
Solution Approach 2:
The trigger guard surface serves as an intermediary element that translates the user's natural finger positioning into laser activation. Rather than requiring direct manipulation of a separate control mechanism, the trigger guard mediates between the user's grip posture and the laser sight's power state, simplifying the interaction.
3Stability of the object's composition
If a rigid switch housing is used, then the switch structure is stable, but it cannot adapt to various handgun frame shapes and configurations
Solution Approach 1:
The switch housing transitions from a rigid structure to a flexible configuration that can dynamically adapt to different handgun frame geometries. The flexible material allows the housing to conform to various shapes while maintaining structural integrity and proper switch functionality across multiple firearm platforms.
Solution Approach 2:
The physical parameters of the switch housing, specifically its rigidity and shape, are changed to enable adaptability. By using flexible material with adjustable geometric parameters, the housing can be configured to match different handgun frame contours while preserving the stable electrical connections and switch operation.
4Ease of operation
If the switch protrudes from the trigger guard, then it is easier to locate and operate, but it interferes with the user's finger movement and disrupts the flush surface
Solution Approach 1:
The switch is nested within or flush with the trigger guard surface rather than protruding outward. This nesting approach allows the switch to remain accessible to the user's finger while maintaining the smooth, continuous contour of the trigger guard, eliminating interference with natural finger movement during gripping and aiming.
