Combination Sight Magnifier Lift Mechanism to Avoid Blind Spots
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing combination sights with a magnifier create a blind spot and obstruct the field of view when switching between magnified and non-magnified modes, affecting shooting observation.
Innovation Solution
A combination sight with a movable connecting mechanism and a magnifier support lifting mechanism that allows the magnifier to be moved between in-use and not-in-use positions without transverse positional change, using a front and rear support rod system, compression spring, and safety switches for quick and stable operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the magnifier is mounted on a rotatable support to switch between configurations, then the system can accommodate both long and short distance aiming, but the magnifier forms an obstruction area that blocks the field of view when not in use
Solution Approach 1:
The magnifier is moved from a transverse/rotatable mounting arrangement to a longitudinal positioning system. By extending the magnifier along the optical axis (another dimension) rather than positioning it laterally, the patent eliminates the obstruction area while maintaining the ability to switch between magnified and non-magnified viewing modes.
2Ease of operation
If traditional handwheel or toggle mechanisms are used to adjust magnification, then the magnifier can be adjusted, but an obstruction area is easily formed that creates a blind spot
Solution Approach 1:
The adjustment mechanism is redesigned to operate in the longitudinal dimension (along the optical axis) rather than laterally. The handwheel or toggle mechanism now controls the extension and retraction of the magnifier along the optical axis, eliminating blind spots while maintaining ease of operation.
3Productivity
If the magnifier is positioned to be readily accessible, then quick switching is possible, but the magnifier may obstruct the field of view during mode transitions
Solution Approach 1:
The magnifier transitions between modes by moving longitudinally along the optical axis rather than laterally across the field of view. This dimensional change enables rapid switching while eliminating obstructions during the transition process.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution ensures the magnifier does not obstruct the field of view during mode transitions, maintaining aiming accuracy and convenience by allowing seamless switching between magnified and non-magnified views.
Implementation Method 1
a compression spring, a push rod, a hinge, two safety switches, and a rotating shaft; a compression spring mounting hole (32) is provided in a middle of the front-sighting-device mounting base (25)

AI summary
The present invention relates to a combination sight supported by a combined support, the combination sight comprising a support, wherein a front-sighting-device mounting base is arranged at the front of the support, and a front sighting device is fixedly connected to the front-sighting-device mounting base; a magnifier connecting base is arranged at the rear of the support; a magnifier is arranged on the magnifier connecting base by means of a movable connecting mechanism; and a magnifier support lifting mechanism is further arranged on the support. In the combination sight supported by a combined support, the magnifier is movably connected to the rear of the support by means of the movable connecting mechanism. When the use of the magnifier is required, the magnifier is lifted by means of the magnifier support lifting mechanism so as to enter an in-use state; and when the use of the magnifier is not required, the magnifier is lowered by means of the magnifier support lifting mechanism so as to enter a not-in-use state, and the magnifier is locked. When the application state of the magnifier changes, the magnifier does not undergo transverse position changes, and therefore the blind spot of a shooter is not enlarged; moreover, the magnifier support lifting mechanism involves easy, convenient and rapid operations.
