Riflescope Knob Interchangeable Indicator Ring Latch Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing riflescope adjustment knobs require tools for replacement and can be cumbersome, leading to the need for multiple knobs for different shooting conditions and risks of loss or damage during replacement.
Innovation Solution
A rotating adjustment knob with a manually actuatable latch that allows for easy exchange of indicator rings without tools, enabling quick adaptation to changing shooting conditions by sliding the ring along the knob's axis and engaging/disengaging with uniformly spaced features.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional adjustment knobs with etched scales are used, then the scale is permanently fixed on the knob, but replacing the scale requires removing the entire knob using tools, which is cumbersome and time-consuming
Solution Approach 1:
The scale is separated from the adjustment knob body, allowing the scale to be an independent, removable component. This segmentation enables the scale to be replaced without removing the entire knob, resolving the contradiction by making the scale adaptable while keeping the knob easy to operate.
Solution Approach 2:
The scale is extracted as a separate element that can be independently removed and replaced. By taking the scale out from the integrated knob structure, users can quickly change scales for different shooting conditions without the complexity of removing the whole knob assembly.
2Adaptability or versatility
If multiple adjustment knobs are carried for different shooting conditions, then adaptability to various conditions is improved, but the device complexity and risk of loss or damage increases
Solution Approach 1:
A single adjustment knob is designed to perform multiple functions by accepting different interchangeable scales. This universal design eliminates the need to carry multiple specialized knobs for different shooting conditions, reducing device complexity while maintaining full adaptability.
Solution Approach 2:
Multiple scales are designed to fit onto a single knob body, creating a nested relationship where different scales can be stored or attached to the same base component. This allows all necessary scales to be managed through one knob rather than requiring separate knobs for each condition.
3Reliability
If scales are etched or inscribed on the adjustment knob, then the scale is durable, but replacing the scale requires tool-based removal and risks dropping components
Solution Approach 1:
The scale is segmented as a separate component that can be independently replaced. This segmentation maintains the durability of each individual scale when in use, while enabling easy replacement without tools if damage occurs, eliminating the risk of dropping components during replacement.
Solution Approach 2:
A retaining mechanism acts as an intermediary between the scale and the knob body, providing a secure connection that prevents accidental dropout during replacement. This intermediary component facilitates tool-free removal and installation while maintaining reliability during normal use.

AI summary
An adjustment device having a rotatable knob for changing an adjustable setting of an aiming device, such as a riflescope. The knob includes a removable indicator ring slidable onto the knob and bearing a scale to provide visual feedback to a shooter regarding an adjustment position of the adjustable setting. The knob further carries a releasable latch that may extend radially outward relative to the knob to retain the indicator ring on the knob when the latch is in the latched position. When the shooter desires to remove and replace the indicator ring, such as in response to a change in shooting conditions, the latch may be released to an unlatched position to allow the indicator ring to be moved off of the knob. The shooter may thereafter insert a replacement indicator ring on the knob.
