Detachable Sight Momentary Sensor Switch Control Logic
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing firearm laser sights require users to physically press a button to turn on and off, which can be slow and noisy, and do not allow for quick or silent operation.
Innovation Solution
A detachable sight with a momentary sensor switch that uses infrared light to control the laser beam, allowing it to be turned on or off by moving a finger to cover or uncover the sensor, enabling fast and silent operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If a permanent on/off switch is used to control the laser beam, then the laser can be turned on and off, but the operation is slow and noisy
Solution Approach 1:
The patent replaces the mechanical button press switch with an optical sensing system. The momentary sensor detects when the shooter's finger blocks the laser beam path, automatically triggering the laser to turn on or off without requiring mechanical contact. This substitution eliminates the noise and time associated with mechanical switch operation while maintaining full control functionality.
2Speed
If a momentary sensor switch is used to control the laser beam, then the operation becomes fast and silent, but the control logic becomes more complex
Solution Approach 1:
The system uses the shooter's own finger as the control mechanism. The finger naturally blocks the laser path when the trigger is pulled, and this same action automatically activates the laser sight. The system serves itself by using the existing shooting motion to control the laser, eliminating the need for separate control switches or complex wiring while achieving momentary operation.
3Reliability
If the laser beam is kept on constantly, then the sight is always ready, but the battery drains faster and the laser may be accidentally activated
Solution Approach 1:
Instead of continuous operation, the laser beam is activated periodically only when needed - specifically when the shooter's finger blocks the sensor. This periodic activation based on trigger pull detection ensures the laser is ready when the shooter intends to fire while conserving battery power during non-shooting periods and preventing accidental activation during storage.
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
The solution provides the fastest and most silent method to activate or deactivate a laser beam on a firearm, enhancing operational speed and stealth by using a touch sensor for control, allowing the laser to be easily turned off when not in use, such as when the firearm is stored.
Implementation Method 1
the momentary sensor can emit infrared light and if the infrared light is deflected, the laser beam emitted from the orifice will be turned off
Implementation Method 2
the momentary sensor can emit infrared light

AI summary
In one aspect, a sight with a momentary switch to control a laser beam on the sight may include a main power switch, a switch with momentary sensor, a plurality of locking screw to lock the sight onto a firearm, an orifice for emitting laser beams, a charging socket, and a laser adjustment screw. When in use, the user can press the main power switch to turn on the sight. In one embodiment, the switch with momentary sensor can emit infrared light and if the infrared light is deflected, the laser beam will be turned off. So, if the user wants to turn off the laser beam, the user can simply move the finger toward the momentary sensor to somewhat covers the momentary sensor to deflect the infrared light emitting therein.
