Integrated Range-Finding Sight for Standard Firearm Mounts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional sights without range finding functions cannot be mounted on firearms using standard holding elements due to their unique shape and size, necessitating specialized mounting solutions.
Innovation Solution
A sight device with integrated range finding capabilities is designed to have a normal size and shape, allowing it to be mounted on a firearm using standard holding elements, incorporating a housing with an objective lens unit, ocular lens unit, erector unit, adjusting unit, light emitting unit, and light receiving unit, all positioned to maintain a symmetrical design and minimize space for a normal appearance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a sight is provided with range finding function, then the sight has range finding capability, but the sight requires a special holding element and cannot be mounted using a normal holding element
Solution Approach 1:
The patent combines the range finding function with the traditional sight structure by integrating a light emitting unit and light receiving unit into the housing. The light emitting unit emits light beams to objects and the light receiving unit receives reflected light beams, enabling range finding while maintaining the sight's external dimensions and shape like a normal sight, thus allowing mounting with standard holding elements
Solution Approach 2:
The sight device achieves multi-functionality by incorporating both sighting and range finding capabilities into a single device. The housing contains not only the objective lens unit and ocular lens unit for sighting but also the light emitting unit and light receiving unit for range finding, allowing the same device to perform multiple functions without requiring special mounting hardware
2Adaptability or versatility
If a sight is provided with range finding function, then the sight has range finding capability, but the sight has an individual shape that differs from a normal sight
Solution Approach 1:
The patent arranges the light emitting unit and light receiving unit within the housing in a configuration that does not increase the external dimensions of the sight. The light emitting unit is disposed on the erector unit with its light beam emitting direction towards the objective lens unit, and the light receiving unit is disposed on the erector unit to receive reflected light, fitting within the existing sight structure without altering its external shape
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 sight device provides both sighting and range finding functions while maintaining a standard size and shape, enabling seamless integration with standard firearm mounts and facilitating user-friendly operation.
Implementation Method 1
The light emitting unit is disposed on the erector unit and includes a light source for emitting a light beam to an object. The light receiving unit is disposed on the erector unit and includes a light sensor for receiving the light beam reflected by the object.
Implementation Method 2
The objective lens unit is disposed at the first end of the housing. The ocular lens unit is disposed at the second end of the housing and opposite to the objective lens unit.

AI summary
In a sight device, an objective lens unit is disposed at an end of a housing. An ocular lens unit is disposed at another end of the housing and opposite to the objective lens unit. An erector unit is disposed between the objective lens unit and the ocular lens unit. A adjusting unit is movably disposed on the housing and radially propped against the erector unit to adjust the erector unit. A light emitting unit is disposed on the erector unit and includes a light source for emitting a light beam to an object. A light receiving unit is disposed on the erector unit and includes a light sensor for receiving the light beam reflected by the object. In any cross section of the housing, any point on the external surface of the housing is approximately equally distant from the second central axis.
