Paintball Launcher Bolt Carrier Striker Reset Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional paintball guns differ significantly from real firearms in structure and operation, making training simulations less realistic and requiring different maintenance procedures, which can hinder effective training and competition.
Innovation Solution
A projectile launcher design featuring a bolt, striker, bolt carrier, and ramp that allows for repositioning of the bolt to a predefined position, enabling a more realistic simulation of firearms by allowing the upper receiver to pivot away from the lower receiver, facilitating bolt carrier disconnection and reconnection with the striker, and utilizing a flexible latch for striker reset and bolt repositioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a conventional paintball marker structure is used, then the device is easier to manufacture and operate differently from real firearms, but the training simulation realism and operational similarity to real firearms deteriorates
Solution Approach 1:
The paintball marker is divided into separate functional modules including an upper receiver, lower receiver, bolt carrier group, and trigger group. This segmentation allows each component to be manufactured independently using conventional processes while enabling the assembly to replicate real firearm disassembly and reassembly procedures, thereby improving training realism without increasing overall manufacturing complexity
Solution Approach 2:
The patent creates a functional and structural copy of real firearm operations within the paintball marker. The bolt carrier group, striker mechanism, and receiver assembly are designed to replicate the operational sequence, safety procedures, and maintenance protocols of conventional firearms, providing realistic training simulation while maintaining the non-lethal paintball function
2Ease of operation
If the bolt carrier disconnects from the striker after resetting, then the striker reset function is achieved, but the bolt may not be properly positioned for accurate firing
Solution Approach 1:
A ramp structure serves as an intermediary element between the bolt carrier and striker assembly. As the bolt carrier moves rearward to reset the striker, the ramp guides the carrier's motion and ensures proper alignment and positioning of the bolt relative to the firing chamber. This intermediary mechanism allows automatic striker resetting while maintaining precise bolt positioning for accurate firing
Solution Approach 2:
The ramp structure is pre-configured to guide the bolt carrier through the correct motion path during the reset cycle. Before the carrier disconnects from the striker, the ramp has already positioned the bolt in the proper alignment for firing. This preliminary positioning action ensures that when disconnection occurs, the bolt is already correctly positioned, eliminating the need for additional adjustment mechanisms

AI summary
A projectile launcher capable of optionally repositioning the bolt to a predefined position using a bolt carrier is disclosed. The launcher, in one aspect, includes a bolt, a striker, a bolt carrier, and a ramp. The bolt, in one example, is configured to be able to move within a bolt chamber. The striker having a striker reset hook is able to move in a direction parallel to a moving direction of the bolt. The bolt carrier, having a fastener, a flexible latch, and a bolt repositioning latch, is attached to the bolt via the fastener. The flexible latch is able to latch to the striker reset hook for resetting the striker during a process of launching a projectile. The ramp facilitates disconnecting the flexible latch from the striker reset hook when the flexible latch moves over the ramp.
