Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a telescopic lens is used in the optical sight device to improve magnification, then the magnification increases, but the device becomes susceptible to even minor shaking, making rapid aiming difficult
Solution Approach 1:
The patent applies dynamics by making the magnification adjustable rather than fixed. The optical sight device allows the user to dynamically change the magnification level based on the shooting situation, enabling rapid aiming at low magnification while providing high magnification when needed for precision shooting.
Solution Approach 2:
The patent changes the magnification parameter from a fixed value to a variable that can be adjusted by the user. This allows the optical characteristics of the sight device to be modified according to different operational requirements, resolving the contradiction between high magnification and rapid aiming capability.
2Loss of information
If aiming information is displayed in existing optical sight devices, then information is provided to the shooter, but parallax occurs causing asthenopia due to repetitive eye accommodation
Solution Approach 1:
The patent introduces an intermediary optical system that includes a first optical system for forming an image of the target and a second optical system for forming a virtual image of the aiming information at the same position. This intermediary arrangement ensures that both the target image and aiming information are in focus simultaneously, eliminating parallax and the associated eye fatigue.
Solution Approach 2:
The patent segments the optical path into distinct optical systems: one for target imaging and another for aiming information display. By separating these functions into different optical pathways that converge at the same focal plane, the system eliminates the parallax effect that would otherwise require the shooter to refocus the eye.
3Productivity
If a non-magnifying (low-magnification) lens is used in the optical dot-sight device for quick aiming, then rapid aiming is achieved, but the device cannot provide magnification for improved precision
Solution Approach 1:
The patent applies dynamics by making the magnification adjustable rather than fixed. The optical sight device allows the user to dynamically change the magnification level based on the shooting situation, enabling rapid aiming at low magnification while providing high magnification when needed for precision shooting.
Solution Approach 2:
The patent makes the optical sight device universal by enabling it to perform multiple functions: rapid aiming at low magnification and precision shooting at high magnification. The adjustable magnification capability allows a single device to serve both the speed and precision requirements that previously required separate devices.

Function Achieved in This Case
The device effectively prevents asthenopia by correcting parallax and allowing for dynamic reticle adjustments, enhancing quick and accurate aiming by displaying aiming information and environmental data without requiring eye refocusing, thus improving shooting speed and accuracy.
Implementation Method 1
The second surface of the reflecting element causes the aiming information to be reflected towards and viewable to an observer
Implementation Method 2
