Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple customized trajectory correcting units are used for different bullet trajectories and calibers, then trajectory correction accuracy is improved, but equipment use efficiency deteriorates
Solution Approach 1:
The patent implements a universal trajectory correcting unit that can accommodate multiple bullet calibers and trajectory types through a standardized interface and adjustable mechanism. The sight assembly includes a caliber selection switch and trajectory selection switch that enable a single unit to be configured for different firearms and ammunition types, eliminating the need for multiple specialized units while maintaining correction accuracy
Solution Approach 2:
The patent employs adjustable and reconfigurable components including a movable sight assembly, selectable caliber settings, and adjustable trajectory correction parameters. These dynamic elements allow the system to adapt to different operational requirements and firearm configurations, providing both precision and versatility
2Ease of manufacture
If traditional bead and sight alignment method is used, then manufacturing simplicity is improved, but aiming speed and accuracy deteriorate
Solution Approach 1:
The patent replaces the traditional mechanical bead-and-sight alignment system with an optical dot sight system that provides a illuminated aiming point. This substitution eliminates the need for precise mechanical alignment of small components while maintaining or improving aiming accuracy and speed through optical projection of the aiming dot
Solution Approach 2:
The patent utilizes an illuminated dot that can be projected in specific colors (typically green or red) to create a high-contrast aiming point against the target background. This optical color/illumination approach enhances target acquisition speed and accuracy compared to traditional mechanical sights
3Measurement precision
If optical sight with telescopic lens is used to enhance accuracy, then aiming precision is improved, but susceptibility to shake increases
Solution Approach 1:
The patent employs a dot sight system with fixed or adjustable magnification parameters that optimize the balance between precision and stability. By controlling the optical parameters (magnification level, dot size, illumination intensity), the system achieves sufficient aiming precision without the excessive shake sensitivity associated with high-magnification telescopic sights
4Productivity
If dot sight with no-magnification lens is used for quick aim, then aiming speed is improved, but view clarity may deteriorate
Solution Approach 1:
The patent utilizes an illuminated dot (typically in green or red spectrum) that provides high-contrast visual marking against various target backgrounds. This optical color approach enhances target acquisition speed while maintaining sufficient view clarity through the brightness and color contrast of the aiming dot
Solution Approach 2:
The dot sight system incorporates adjustable parameters including dot brightness, dot size, and illumination intensity that can be optimized for different lighting conditions and target types, maintaining both quick aiming capability and view clarity across various operational environments

AI summary
Disclosed is an apparatus for multi-correcting a trajectory, the apparatus comprising a trajectory correcting unit in which a polygonal cam comprising a plurality of surfaces different in distance from a rotary center is rotatably installed between a dot sight or an optical signal and a firearm to adjust an angle between an optical axis of the dot sight or optical sight and a gun barrel axis of the firearm, wherein the trajectory correcting unit is installed to be movable in an axis direction, and coaxially provided with two or more polygonal cams to respectively set trajectory correcting angles corresponding to distances in accordance with calibers of a bullet and the kinds of bullet. With this, one dot sight or optical sight can be mounted to firearms using bullets different in the trajectory or firearms different in a caliber from one another, thereby enhancing equipment use efficiency.
