One-Hand Scope Lens Adjustment via Adjacent Controllers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional firearm scopes require separate and distant controllers for adjusting optical lenses, leading to inefficient and cumbersome adjustments, slowing down target acquisition due to the need for manual optimization of optical parameters.
Innovation Solution
A lens adjustment device with adjacent controllers for both optical lens groups, allowing simultaneous adjustment of the first and second lens groups via a mechanical arrangement that eliminates the need for complex structures, enabling one-hand operation and real-time field of view observation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the controllers for adjusting the objective lens and ocular lens are placed at distant locations (such as at the two end portions of the tubular housing), then each lens can be adjusted independently with dedicated controls, but the user must move their hand and fingers back and forth between the two controllers, significantly increasing the time and complexity of adjustment operations
Solution Approach 1:
The patent combines the controllers for adjusting the objective lens and ocular lens into a single integrated control unit located at one position on the scope. This merging of previously separate controllers allows the user to adjust both lenses without moving their hand between distant locations, directly resolving the technical contradiction by improving ease of operation while reducing adjustment time.
2Measurement precision
If separate controllers are used for the objective lens and ocular assembly, then each lens can be precisely adjusted individually, but the adjustment process requires multiple back-and-forth operations and is quite troublesome
Solution Approach 1:
The integrated controller performs multiple adjustment functions for both the objective lens and ocular assembly through a single control unit. This multi-functional design maintains precise adjustment capability for each lens while simplifying the operational complexity, as the user interacts with one controller rather than multiple separate ones.
3Adaptability or versatility
If the controllers are placed far from one another on the lens housing, then each controller can be dedicated to a specific lens, but a significant distance exists between the two points of necessary manipulation, making one-hand operation difficult
Solution Approach 1:
By merging the controllers into a single integrated unit positioned for easy access, the patent enables one-hand operation while maintaining full adjustment functionality. The combined controller eliminates the need to reach between distant control points, directly improving both adaptability to one-hand operation and ease of manipulation.

AI summary
A lens adjustment device for a scope includes an elongated tubular body having an objective end portion and an eyepiece end portion so as to define a rotation axial therealong, a first lens group and a second lens group slidably and operatively assembled at the objective end portion and the eyepiece end portion respectively, a first controller arranged for controlling the first lens group and the second lens group, and a second controller arranged for controlling the second lens group individually. The first controller and the second controller are arranged adjacently with each other on the outer tubular casing of the scope facilitating the adjustment operation of the scope so as to enable one-hand operation.
