Auto-Locking Turret Knob for Rapid, Stable Adjustments
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional turrets on firearms require separate locking mechanisms or screw-on caps, which can hinder quick adjustments in high-pressure situations like combat or hunting, wasting valuable time and potentially alerting enemies or animals to the user's position.
Innovation Solution
A turret design with an auto-locking mechanism that allows adjustment through a single knob, transitioning between locked and unlocked states, preventing unintentional adjustments by automatically returning to the locked position when released.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate locking mechanisms or screw-on caps are used to prevent inadvertent adjustment, then the turret remains secure at desired positions, but the user cannot quickly adjust the turret in high-pressure situations
Solution Approach 1:
The patent combines the locking mechanism and adjustment mechanism into a single integrated system. The adjustment knob simultaneously performs both adjustment and locking functions - when rotated, it adjusts the turret position, and when released, it automatically locks. This eliminates the need for separate locking mechanisms or screw-on caps, allowing users to quickly adjust and secure the turret in one continuous motion without wasting time on additional operations.
Solution Approach 2:
The turret features an automatic locking system that self-activates when the adjustment knob is released. The spring-loaded detent mechanism automatically engages with the adjustment knob to lock it in place without requiring any additional user action. This self-service locking feature ensures the turret remains secure at the desired position while eliminating the need for separate locking operations, thus reducing adjustment time while maintaining reliability.
2Reliability
If screw-on caps are used to cover the turret, then inadvertent adjustment is prevented, but additional operations are required before adjustment can be made
Solution Approach 1:
The patent merges the protective cap function into the adjustment knob itself. The adjustment knob serves as both the adjustment mechanism and the protective cover - it is always accessible for adjustment while preventing inadvertent movement through its automatic locking feature. This eliminates the need for separate screw-on caps and the additional operations required to remove them before adjustment.
Solution Approach 2:
The adjustment knob provides self-protective functionality through its automatic locking mechanism. When not in use, the spring-loaded detent automatically engages to lock the knob in place, preventing accidental adjustment without requiring a separate cap. When adjustment is needed, the user simply rotates the knob, which automatically unlocks and allows adjustment, then re-locks when released. This maintains both protection and ease of operation.
3Reliability
If separate locking mechanisms are used, then the turret can be locked or unlocked by the user, but extra movements and operations are required that could alert an enemy combatant or animal
Solution Approach 1:
The patent combines the locking and unlocking functions into the single act of rotating and releasing the adjustment knob. The adjustment knob integrates both the adjustment function and the locking/unlocking function - rotating it unlocks and allows adjustment, while releasing it automatically locks. This eliminates the need for separate locking mechanisms and reduces the number of operations from multiple discrete actions to one continuous motion, thereby reducing device complexity and the risk of detection.
Solution Approach 2:
The automatic locking mechanism provides self-service functionality that eliminates the need for separate user-initiated locking operations. When the adjustment knob is released after adjustment, the spring-loaded detent automatically engages to lock the knob in place without requiring any additional user action. This reduces the total number of operations from multiple separate actions (unlock, adjust, lock) to a single action (adjust and release), simplifying the overall process and reducing the time and movements required.

AI summary
A turret is configured to adjust a position of an alignment stage coupled to the turret. The turret can include an adjustment knob configured to be actuatable in a plurality of adjustment directions to adjust the position of the alignment stage. The turret can further include a lock configured to prevent movement of the adjustment knob in the plurality of adjustment directions. The adjustment knob can be configured to be actuatable to transition the adjustment knob between a locked state in which the lock is engaged and an unlocked state in which the lock is released. With the adjustment knob in the unlocked state, the adjustment knob is actuatable in the plurality of adjustment directions.
