Holster Release Lever Actuation for Gun Ejection Port
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing handgun holsters with safety devices using the spent casing ejection port for locking mechanisms are unreliable and inconvenient, particularly in emergency situations, as they often require thumb actuation deep within the holster, which can be cumbersome and unsuitable for various handgun models and configurations.
Innovation Solution
A handgun holster with a U-shaped latch engaging the ejection port and a release lever actuated by the forefinger, featuring a wide outer recess for ergonomic contact and a slanting peg mechanism that allows for easy and quick release with minimal finger movement, ensuring reliable and convenient operation for both right- and left-handed users.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the release mechanism is placed deep within the holster to protect it from accidental actuation, then security against unauthorized release is improved, but ease of operation deteriorates as the user must insert their finger deep into the holster to reach the release mechanism
Solution Approach 1:
The release mechanism is extended outward from the holster body along the longitudinal axis, creating a lever that projects beyond the holster's rear wall. This dimensional extension allows the release actuation point to be positioned externally rather than deep inside the holster, resolving the contradiction by maintaining security through the lever's constrained motion path while improving ease of operation through accessible actuation positioning
2Reliability
If the release mechanism requires precise finger insertion deep into the holster, then accidental actuation is prevented, but the device becomes unsuitable for users with bulky fingers and reduces productivity in emergency situations
Solution Approach 1:
The lever extends the release mechanism externally, creating a large-amplitude arc motion that can be actuated from a comfortable external position rather than requiring deep finger insertion. This maintains security through the mechanical constraint of the lever's pivot point while dramatically improving productivity by enabling rapid actuation with any finger size during emergency situations
Solution Approach 2:
The lever provides a dynamic arc-shaped motion path for the release actuation, allowing the user's finger to follow a natural sweeping motion rather than requiring precise static insertion deep into the holster. This dynamic approach maintains security through the constrained pivot mechanism while improving speed by accommodating natural finger movements during high-stress extraction scenarios
3Adaptability or versatility
If the holster design is adapted to accommodate tactical accessories like lights and laser sights, then versatility is improved, but the space for the release mechanism is reduced
Solution Approach 1:
The lever extends the release mechanism along the longitudinal axis outward from the holster body, utilizing the external space rather than competing for internal volume. This allows the holster to accommodate tactical accessories like lights and laser sights in the rear mounting area while the lever provides adequate actuation space externally, resolving the contradiction between accessory compatibility and ease of operation
