Silicone Trigger Cover Isolates Vibration and Roughness
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing trigger mechanisms in crossbows and firearms can be rough, leading to accidental string release and increased target panic, as they lack a defined force indication for trigger release, resulting in less accurate shots.
Innovation Solution
A slip-on trigger cover with a compressible section made of silicone, featuring a tubular arc shape and flexible supports, which insulates the user from rough sear mechanisms and vibrations, allowing for a more fluid trigger pull without accidentally releasing the bowstring, and reduces the force required for sear release.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a trigger mechanism is used in crossbows or firearms, then the projectile can be fired, but the rough sear mechanism causes vibration and makes the shooter feel the roughness, resulting in less accurate shots
Solution Approach 1:
The patent introduces a trigger cover as an intermediary component between the shooter's finger and the trigger mechanism. This cover is made of elastomeric material that cushions and isolates the shooter from the rough sear mechanism and vibrations, while still allowing the trigger to be actuated effectively.
2Ease of operation
If the trigger pull force is reduced for easier operation, then the archer can feel the trigger position better, but it becomes easier to accidentally release the bowstring
Solution Approach 1:
The patent changes the physical parameters of the trigger interface by introducing an elastomeric cover with specific durometer ratings (50-65 for light touch, 80-90 for medium touch). This allows optimization of the trigger pull characteristics while maintaining reliable engagement, as the material properties can be selected to balance smooth operation with adequate engagement force.
3Manufacturing precision
If the sear surfaces are polished to eliminate roughness, then the trigger pull becomes smoother, but the manufacturing complexity and time increase
Solution Approach 1:
The patent extracts the smoothing function from the trigger mechanism itself and relocates it to a separate elastomeric cover component. Instead of requiring complex polishing processes on the metal sear surfaces, the roughness is eliminated by the compliant material of the cover, which can be manufactured more simply through molding processes.
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 trigger pull cover provides a smoother, consistent firing experience by insulating the user from rough trigger mechanisms, minimizing target panic and improving shot accuracy by allowing precise trigger positioning without accidental releases.
Implementation Method 1
The silicone material will store energy while being compressed by a finger. The stored energy will reduce the amount of force required to bring the trigger to a sear release.
Implementation Method 2
insulates a user from feeling a rough sear mechanism or a vibration generated by pulling the trigger

AI summary
A release trigger pull cover preferably includes a slip-on trigger tube and a compressible section. An inner perimeter of the slip-on trigger tube is sized to receive a trigger of a string release. The compressible section preferably includes a trigger portion and at least two flexible supports. One end of the at least two flexible projections extend from a backside of the trigger portion. An opposing end of the at least two flexible projections are engaged with a front of the slip-on trigger tube. A firearm trigger pull cover preferably includes a slip-on trigger tube and front pad. An inner perimeter of the slip-on trigger tube is sized to receive a trigger of a firearm. A front area of the front pad includes a widthwise flat surface and a plurality of vertical ridges. An alternative embodiment of the firearm trigger pull cover includes a trigger tube and cantilever pull.
