Optical Scope Turret Engagement Lock for Tool-Less Re-Zeroing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing optical scope adjustment mechanisms require the use of tools for re-zeroing, which can be inconvenient and time-consuming.
Innovation Solution
A tool-less re-zeroing system for optical scopes, utilizing a dial and rotating member that can be engaged or disengaged without tools, allowing for precise adjustment of the scope's aim without the need for hex keys or other tools.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a hex key and grub screw are used to loosen and reposition the dial for re-zeroing, then the dial can be adjusted relative to the threaded member, but the process becomes time-consuming and requires additional tools
Solution Approach 1:
The invention extracts and removes the hex key and grub screw from the re-zeroing process. Instead of using these separate tools and components, the dial is designed with a pull feature that allows direct manual manipulation. When the user pulls the dial axially outward, it automatically disengages from the threaded member without requiring any tools, enabling quick repositioning for re-zeroing.
Solution Approach 2:
The dial incorporates self-service features including a pull feature for easy disengagement and a detent mechanism with a ramped surface that automatically engages the dial with the threaded member when pushed inward. The spring-loaded detent provides automatic locking without requiring tools or additional operations, making the entire re-zeroing process self-contained and tool-free.
2Reliability
If a grub screw is used to secure the dial to the threaded member, then the dial can be fixed in position, but the mechanism requires tools and increases device complexity
Solution Approach 1:
The invention removes the grub screw entirely from the system. Instead of using a screw that requires a hex key for installation and adjustment, the dial features an axial pull mechanism that allows the user to manually disengage and reposition the dial. This extraction of the screw mechanism simplifies the overall device structure while maintaining reliable fixation through the detent engagement system.
Solution Approach 2:
The fixation mechanism uses a spring-loaded detent with a ramped surface that automatically engages the dial with the threaded member when the dial is pushed inward. This self-acting mechanism provides reliable fixation without requiring any tools or manual screw tightening, reducing device complexity while ensuring secure connection.
3Measurement precision
If the dial is always engaged with the threaded member for co-rotation, then aiming adjustments are precise, but re-zeroing requires tool intervention and disengagement
Solution Approach 1:
The invention implements a dynamic engagement system where the dial can transition between engaged and disengaged states through simple axial movement. When pushed inward, the dial engages with the threaded member for precise co-rotation during aiming adjustments. When pulled outward, the dial disengages automatically, allowing independent rotation for re-zeroing without tools. This dynamic state change enables both precise measurement and easy repositioning.
Solution Approach 2:
The detent mechanism acts as an intermediary between the dial and threaded member, providing controlled engagement and disengagement. The spring-loaded detent with its ramped surface allows the dial to be easily disengaged by pulling and automatically re-engaged by pushing, facilitating smooth transitions between precision adjustment mode and re-zeroing mode without requiring tools or complex operations.
