Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing variable-magnification sights suffer from reduced reliability due to numerous movable parts and poor adjustment accuracy, while fixed-magnification sights lack adaptability to varying shooting conditions.
Innovation Solution
A combined sight of a variable-reticle red dot sight and a magnifier, featuring a magnifier flipping mechanism and a magnetic Hall switch, allows the reticle pattern to change between dot-circle quick aiming and sniping modes by flipping the magnifier, enhancing adaptability and accuracy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If variable-magnification sights use multiple movable mechanisms (variable-magnification lens group, magnification ring) to achieve adaptability to different shooting conditions, then adaptability is improved, but reliability decreases due to increased component complexity and more movable parts
Solution Approach 1:
The sight system is divided into two independent modules: a fixed-magnification red dot sight module and a magnifier module. The red dot sight maintains a simple, reliable structure with no movable magnification mechanisms, while the magnifier provides variable magnification capability. This segmentation allows each module to optimize for its specific function, resolving the contradiction between adaptability and reliability.
Solution Approach 2:
The magnifier is designed to be mounted on top of the red dot sight, with the magnifier's optical axis aligned with the red dot sight's optical axis. The magnifier can be flipped between a working position (covering the objective lens) and a non-working position (out of the optical path). This nested configuration allows the magnifier to provide variable magnification adaptability while the red dot sight maintains its simple, reliable fixed-magnification structure.
2Reliability
If fixed-magnification sights use a simple optical path structure with no movable mechanisms, then reliability is improved, but adaptability to varying shooting conditions deteriorates
Solution Approach 1:
The invention merges a fixed-magnification red dot sight with a magnifier into a combined sight system. The red dot sight provides reliable close-range aiming with its simple fixed-magnification structure, while the magnifier adds long-range magnification capability. When the magnifier is in the working position, it combines with the red dot sight to provide magnified viewing for distant targets, thus achieving adaptability without compromising the reliability of the base red dot sight.
3Measurement precision
If traditional sights adjust magnification through handwheels or toggles, then magnification adjustment is achieved, but adjustment accuracy deteriorates due to manual operation limitations
Solution Approach 1:
The invention replaces the traditional mechanical handwheel or toggle magnification adjustment mechanism with a magnetic field-based detection system. A magnetic Hall switch detects the position of a magnet attached to the magnifier, automatically determining whether the magnifier is in the working or non-working position. This substitution of mechanical adjustment with magnetic field detection eliminates manual operation errors and achieves precise, reliable position detection.

AI summary
The present utility model relates to a combined sight of a variable-reticle red dot sight and a magnifier, comprising a support. A positioning groove is provided on the top of the front part of the support, and a red dot sight is provided in the positioning groove; a magnifier flip-up mechanism is provided above the rear part of the support, and the magnifier flip-up mechanism is movably connected to a magnifier. According to the combined sight of a variable-reticle red dot sight and a magnifier, when the magnifier is flipped up, a magnet in the magnifier flip-up mechanism does not make contact with a magnetic switch, and at the moment, a reticle pattern in the red dot sight is in a dot-circle quick aiming mode; and when the magnifier is flipped back, the magnet is in contact with the magnetic switch, and the reticle pattern in the red dot sight is changed to be in a sniping mode. The combined sight has the advantages of a reflex sight and a telescopic sight: in a state that only the red dot sight is used, the exit pupil distance is avoided, the parallax is small, the field of view is large, the reticle is simple and clear, and aiming is quick; and in a state that the combined sight is used, the reticle has complete data, and long-range aiming is more accurate.
