Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The axis of the optical sighting system in firearms often becomes displaced from the barrel axis due to material strains and thermal changes, requiring frequent recalibration for accurate bore sighting.
Innovation Solution
A muzzle-end adapter with a main operating shaft and conical disks that provides rectilinear motion to expand centering fingers for symmetrical alignment within the firearm bore, allowing for precise bore sighting of large caliber guns.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the optical sighting system is rigidly fixed to the barrel, then the alignment is stable, but the system cannot adapt to thermal expansion and material strain changes
Solution Approach 1:
The patent employs a dynamic alignment mechanism where the optical sighting system can adjust its position relative to the barrel through a calibration process. The adapter assembly allows for movement and adjustment of the optical system along the barrel axis and laterally, enabling the system to adapt to thermal expansion and material strain changes while maintaining accurate alignment.
2Measurement precision
If frequent recalibration is performed to maintain accuracy, then the bore sighting precision is improved, but the time and operational efficiency are reduced
Solution Approach 1:
The patent implements a preliminary alignment feature through the adapter assembly that can be quickly installed and configured before firing operations. The adapter includes pre-configured alignment features and a rapid adjustment mechanism that allows operators to perform bore sighting setup in advance, reducing the need for frequent recalibrations during operational sequences.
3Adaptability or versatility
If a complex adjustment mechanism is used to maintain alignment, then the adaptability to environmental changes is improved, but the device complexity increases
Solution Approach 1:
The patent introduces an adapter assembly as an intermediary component between the barrel and the optical sighting system. This adapter serves as a mediator that absorbs and compensates for thermal expansion and material strain effects, allowing the optical system to maintain alignment without requiring complex active adjustment mechanisms. The adapter's design simplifies the overall system while providing the necessary adaptability.
