Optical Sight Rangefinding Layout Through Handwheel Gaps
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Optical sights with integrated rangefinders face increased ranging errors and larger volume due to the mechanical interference from adjustment handwheels, which necessitate mounting the rangefinder outside the handwheels, leading to an excessive distance between the detection ray and the lens barrel axis.
Innovation Solution
An aiming assistance device is mounted on the optical sight, incorporating a detection mechanism that emits a detection ray through a gap between adjustment handwheels, with a display and light deflection module to merge measurement information with the optical sight's image, reducing the overall size and improving accuracy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-generated harmful factors
If the rangefinder is mounted outside the highest point of the adjustment handwheels to avoid mechanical interference, then the mechanical interference is avoided, but the distance between the detection ray and the lens barrel axis becomes excessive, leading to increased ranging error and larger volume
Solution Approach 1:
The patent utilizes the gap area between adjacent adjustment handwheels (a spatial dimension) to route the detection ray, allowing the rangefinder to be positioned without excessive distance from the lens barrel axis while avoiding mechanical interference with the handwheels
2Object-generated harmful factors
If the rangefinder is mounted outside the highest point of the adjustment handwheels to avoid mechanical interference, then the mechanical interference is avoided, but the volume of the optical sight becomes larger, affecting portability
Solution Approach 1:
The patent utilizes the gap area between adjacent adjustment handwheels (a spatial dimension) to route the detection ray, allowing the rangefinder to be positioned closer to the lens barrel axis, thereby reducing the overall volume of the optical sight while avoiding mechanical interference
3Object-generated harmful factors
If the detection mechanism protrudes more to accommodate the rangefinder, then the mechanical interference is avoided, but the portability is reduced
Solution Approach 1:
The patent utilizes the gap area between adjacent adjustment handwheels (a spatial dimension) to route the detection ray, allowing the detection mechanism to be positioned with minimal protrusion while avoiding mechanical interference with the handwheels
