Firearm Muzzle Accessory Connection Device with Chamfer Teeth
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing firearms accessories often experience imperfect connections due to mismatched threading at the discharge end of rifle barrels, leading to hazardous shooting conditions, tedious alignment processes, and difficulty in removing accessories, especially when different materials expand at different rates and carbon lock occurs.
Innovation Solution
A rifle accessory connection device with a housing, spring, and locking ring featuring chamfer teeth, which allows for quick and precise attachment of accessories by engaging chamfer teeth on the locking ring and attachment ring, enabling fine-tuning adjustments and secure connections without direct contact with the barrel surface.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional threaded connections are used to attach accessories to rifle barrels, then secure attachment can be achieved, but the alignment process becomes tedious and time-consuming requiring additional parts like shims and washers
Solution Approach 1:
The patent introduces a connection device as an intermediary component between the rifle barrel and accessory. This device includes a body with external threading that attaches to the barrel, and a locking mechanism with chamfer teeth that engage with the accessory. The intermediary device provides built-in alignment features (chamfer teeth) that eliminate the need for separate shims and washers, while ensuring secure attachment through the locking mechanism.
Solution Approach 2:
The connection device is segmented into distinct functional components: a body portion with external threading for barrel attachment, a locking ring with chamfer teeth for alignment, and engagement features for the accessory. This segmentation allows each component to perform its specific function efficiently - the threading provides secure attachment while the chamfer teeth provide quick alignment, resolving the time-consuming alignment problem.
2Reliability
If accessories are tightly secured to hot barrels, then secure connection is maintained, but removal becomes difficult due to thermal expansion and carbon lock
Solution Approach 1:
The connection device incorporates a dynamic locking mechanism with a locking ring that can be easily engaged and disengaged. The locking ring features chamfer teeth that provide incremental adjustment capability, allowing the user to dynamically adjust the connection during use. This dynamic design maintains secure connection when needed while enabling easy removal when required, overcoming the static nature of traditional threaded connections.
Solution Approach 2:
The chamfer teeth on the locking ring provide preliminary alignment features that guide the accessory into proper position before final locking. This preliminary action ensures correct alignment is achieved before the locking mechanism fully engages, preventing misalignment issues that could complicate removal later, while still allowing easy disengagement when needed.
3Measurement precision
If fine-tuning adjustments are needed for competition shooting, then alignment precision can be improved, but the adjustment process becomes more complex and time-consuming
Solution Approach 1:
The locking ring features asymmetric chamfer teeth that provide incremental adjustment capabilities. The chamfer teeth are positioned to allow precise angular adjustments in specific directions, enabling fine-tuning of the accessory alignment. This asymmetric design provides precision control without requiring complex adjustment mechanisms, as the tooth geometry itself enables the fine adjustments needed for competition shooting.
