Adjusting Knob Mechanism with Dual Clicking Gears for Variable Sound Intervals
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional adjusting knob mechanisms require replacement to change clicking sound intervals, which is inconvenient for users.
Innovation Solution
The mechanism incorporates two clicking gears and an adjustable cover to produce different sound intervals, allowing users to control the sound intervals by changing the position of the cover, enabling both coarse and fine adjustments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single clicking gear is used in the adjusting knob mechanism, then the structure is simple, but the clicking sound interval cannot be changed without replacing the entire mechanism
Solution Approach 1:
The patent divides the clicking gear into two separate clicking gears (first clicking gear with first grooves and second clicking gear with second grooves). Each gear has a different groove spacing pattern, allowing different clicking sound intervals. The movable element can selectively engage with either gear, enabling interval change without replacing the entire mechanism.
Solution Approach 2:
The patent introduces a movable element that can dynamically switch between two positions: first position for engaging the first clicking gear, and second position for engaging the second clicking gear. This dynamic reconfiguration allows the mechanism to adapt its clicking sound interval based on operational needs.
2Ease of operation
If the movable element is positioned at the first position, then the first ball member engages the first clicking gear for coarse adjustment, but the second ball member cannot engage the second clicking gear
Solution Approach 1:
The movable element dynamically changes position between first and second positions. At the first position, it enables coarse adjustment through the first clicking gear while preventing engagement with the second clicking gear. At the second position, it enables fine adjustment through the second clicking gear. This dynamic switching resolves the contradiction by providing both adjustment types at different operational states.
3Ease of operation
If the movable element is positioned at the second position, then the second ball member engages the second clicking gear for fine adjustment, but the first ball member cannot engage the first clicking gear
Solution Approach 1:
The movable element's position determines which clicking gear is engaged. At the second position, it enables fine adjustment through the second clicking gear while preventing engagement with the first clicking gear. This dynamic behavior allows the mechanism to provide both coarse and fine adjustment capabilities at different operational states, resolving the contradiction.
4Adaptability or versatility
If the adjusting cover is rotated to move the movable element axially, then the clicking sound interval can be changed, but the structure becomes more complex
Solution Approach 1:
The connecting mechanism translates the rotational motion of the adjusting cover into axial movement of the movable element. This dynamic transformation allows the user to switch between different clicking sound intervals by simply rotating the adjusting cover, without requiring complex manual assembly or replacement operations.

Function Achieved in This Case
Enables adjustable sound intervals and precise adjustments for bullet impact point correction, enhancing user convenience and flexibility in operation.
Implementation Method 1
the ball member is forced to engage with the first groove or the second groove by an elastic force generated by the elastic member
Implementation Method 2
the first ball member is forced against the first clicking gear by a first elastic force generated by the first elastic member
Implementation Method 3
the second ball member is forced against the second clicking gear by a second elastic force generated by the second elastic member

AI summary
In an adjusting knob mechanism, a base includes a first supporting portion and a second supporting portion. A first clicking gear includes a plurality of first indentations and disposed on the first supporting portion. A second clicking gear includes a plurality of second indentations and disposed on the second supporting portion. A limiting element is disposed on the base. A movable element is disposed within the limiting element and configured to move in an axial direction of the base relative to the limiting element. A connecting mechanism extends into the limiting element. An adjusting cover is connected to the movable element by the connecting mechanism, so as to move the movable element in the axial direction of the base relative to the limiting element and the second clicking gear. The adjusting cover is configured to rotate the limiting element and the movable element through the connecting mechanism.
