Rotatable Reticle for Viewing Instrument Aiming Correction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing viewing instruments for armored vehicles fail to correct for errors in point of impact caused by the inclined position of the objective unit, limiting the accuracy of aiming and targeting systems when coupled with a weapon system, especially in the absence of electrical or electronic aids.
Innovation Solution
A viewing instrument with a reticle arranged in an intermediate image plane, rotatable relative to the optical axis, allows for manual correction of the inclined position without electrical or electronic means, ensuring accurate aiming by aligning the reticle with gravity using a visible spirit level and swivel joint mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the objective unit is coupled to a weapon system for aiming purposes, then the viewing instrument enables target acquisition and observation functions, but the inclined position of the objective unit causes errors in point of impact location that cannot be corrected without electrical or electronic auxiliary means
Solution Approach 1:
The patent replaces electrical or electronic correction mechanisms with a purely mechanical solution: a rotatable reticle that can be manually rotated about the optical axis to correct for inclined position errors. This mechanical substitution eliminates dependence on complex electrical systems while maintaining the ability to compensate for positioning errors.
Solution Approach 2:
The reticle is made rotatable about the optical axis, transforming a static component into a dynamic one that can be adjusted manually. This dynamic adjustment allows the reticle to be oriented at different angles to compensate for the inclined position of the objective unit, providing flexibility without requiring electrical actuation.
2Reliability
If electrical or electronic auxiliary means are used to correct the inclined position, then the point of impact location can be compensated, but the viewing instrument becomes dependent on the electrical system which may fail
Solution Approach 1:
The patent replaces electrical or electronic correction mechanisms with a purely mechanical solution: a rotatable reticle that can be manually rotated about the optical axis to correct for inclined position errors. This mechanical substitution eliminates dependence on complex electrical systems while maintaining the ability to compensate for positioning errors.
Solution Approach 2:
The operator can manually rotate the reticle to correct for inclined position errors without requiring external electrical or electronic assistance. This self-service capability ensures that the viewing instrument remains operational and accurate even when the vehicle's electrical system fails.
3Ease of operation
If a reticle is arranged in the intermediate image plane and made rotatable about the optical axis, then manual correction of inclined position is enabled, but the device complexity increases due to the additional rotation mechanism
Solution Approach 1:
The reticle is made rotatable about the optical axis, transforming a static component into a dynamic one that can be adjusted manually. This dynamic adjustment allows the reticle to be oriented at different angles to compensate for the inclined position of the objective unit, providing flexibility without requiring electrical actuation.
Solution Approach 2:
The rotation capability is localized specifically to the reticle component rather than the entire viewing instrument. This localized quality allows manual correction of inclined position while minimizing the overall device complexity, as only the reticle and its mounting structure require rotational capability.
