Finger-Adjustable Scope Mechanism for Tool-Free Torque Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Optical scopes, such as rifle scopes, face challenges in adjusting for varying environmental conditions and ballistic properties without requiring tools, as existing adjustment mechanisms often necessitate the use of tools for precise torque transmission and reticle alignment.
Innovation Solution
A finger-adjustable scope adjustment mechanism that includes a first surface and a second surface configured to engage axially when force is applied, with a member that can be actuated using only one or more human fingers, allowing for torque transmission and reticle movement without the need for tools, utilizing features like conical splines, high-friction surfaces, and finger-adjustable screws.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional adjustment mechanisms are used, then torque transmission and reticle alignment are achieved, but tool usage is required for adjustment
Solution Approach 1:
The adjustment mechanism allows the user to directly apply torque to the erector tube through the adjustment knob without requiring external tools. The knurled surface on the adjustment knob provides sufficient friction for finger actuation, enabling the mechanism to serve itself through direct user interaction.
Solution Approach 2:
The patent replaces traditional tool-based mechanical adjustment systems with a finger-actuated system. The adjustment knob with knurled surface substitutes for tool interfaces, and the direct coupling mechanism replaces complex tool engagement systems, achieving tool-free operation while maintaining reliable torque transmission.
2Ease of operation
If finger-adjustable mechanism is used, then tool-free operation is achieved, but adjustment precision may be compromised
Solution Approach 1:
The adjustment mechanism is segmented into distinct functional components: the adjustment knob for coarse positioning, the erector tube for precise reticle movement, and the coupling mechanism for torque transmission. This segmentation allows finger actuation at the knob level while maintaining precision through the dedicated erector tube adjustment path.
Solution Approach 2:
The adjustment knob serves as an intermediary between the user's fingers and the erector tube. It translates finger rotational motion into precise axial movement of the erector tube through the coupling mechanism, mediating between the imprecise finger input and the precise adjustment requirement.
3Productivity
If direct torque coupling is used, then adjustment responsiveness is improved, but mechanism complexity increases
Solution Approach 1:
The adjustment knob and erector tube coupling are merged into a single integrated assembly. The knurled surface, torque transmission elements, and adjustment interface are combined in one compact unit, reducing the number of separate components while maintaining direct torque coupling for responsive adjustment.
Solution Approach 2:
The adjustment knob performs multiple functions simultaneously: providing finger grip through knurling, transmitting torque to the erector tube, and enabling direct user interaction. This multi-functionality reduces the need for separate components, simplifying the overall mechanism while maintaining responsiveness.
