Tool-Free Re-Zero Optical Scope Knob Adjustment Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing optical scope adjustment mechanisms require tool usage for re-zeroing, which can be inconvenient and may lead to inaccuracies in aiming adjustments due to environmental factors like wind and bullet trajectory changes.
Innovation Solution
The design incorporates a dial that can engage and disengage with a rotating member, allowing for tool-free re-zeroing through a mechanism involving a retainer device, click mechanism, and specific groove and ridge configurations, enabling tactile and audible feedback for precise adjustments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a grub screw coupling mechanism is used to allow dial rotation for re-zeroing, then re-zeroing capability is achieved, but tool usage is required and the mechanism becomes more complex
Solution Approach 1:
The dial incorporates a self-contained release mechanism with a button that the user presses to disengage the dial from the threaded member. This self-service feature eliminates the need for external tools (like hex keys) to loosen the grub screw, allowing the user to independently perform re-zeroing operations by simply pressing the release button and rotating the dial.
2Adaptability or versatility
If a grub screw coupling mechanism is used for dial adjustment, then re-zeroing is possible, but the device structure becomes more complex
Solution Approach 1:
The release button mechanism is integrated directly into the dial structure, merging the release function with the dial itself rather than being a separate component. The button is positioned on the dial's outer periphery and works in conjunction with a cam surface and latch feature that are part of the dial assembly, reducing overall mechanism complexity while maintaining re-zeroing capability.
3Adaptability or versatility
If the dial is made movable for re-zeroing, then adjustability is improved, but the coupling between dial and threaded member becomes less stable
Solution Approach 1:
The coupling between the dial and threaded member transitions from a static fixed connection to a dynamic conditional connection. When the release button is not pressed, the dial is firmly coupled to the threaded member through the cam surface and latch, ensuring stable co-rotation during aiming adjustments. When the button is pressed, the coupling dynamically disengages, allowing independent dial rotation for re-zeroing. This dynamic switching mechanism maintains reliability during normal operation while enabling adjustability when needed.

AI summary
Embodiments of the present disclosure relate to a user-zeroable adjustment knob for an optical aiming device. The adjustment knob includes a rotating member rotatable about an axis of rotation to change a setting of the optical aiming device, the rotating member including a rotating member clutch surface centered on the axis of rotation and a dial comprising a dial clutch surface, and wherein the dial is movable between an engaged position where the dial clutch surface is engaged with the rotating member clutch surface, and a disengaged position in which the dial clutch surface is disengaged from the rotating member clutch surface, allowing the dial to be rotated relative to the rotating member to set a zero position.
