Solution Overview

Problem

Slim-profile magazine releases on handguns require counter-intuitive or restrictive force and motion, leading to potential loss of control over the handgun's direction during actuation.

Innovation Solution

A magazine release assembly with interlocking protrusions and recesses, and a button with a sloped surface, which reduces the force and direction of motion needed for actuation, and includes a catch spring mechanism to prevent accidental release, allowing for easier and safer operation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Shape

If a slim-profile magazine release is used, then the handgun maintains a streamlined appearance and compact size, but the magazine release becomes difficult to operate requiring counter-intuitive force and motion

Engineering Contradiction:
Improveslim-profile designVSAvoidmagazine release actuation
Core Design Contradiction:
ShapeVSEase of operation

Solution Approach 1:

The magazine release button incorporates a curved or rounded contact surface that conforms to the natural contour of the user's finger. This curvature allows the finger to apply force in a more natural direction, improving ease of operation while maintaining the slim-profile aesthetic of the handgun.

Inventive Principle:
Principle #14Spheroidality (Curvature)

2Shape

If a slim-profile magazine release is used, then the handgun remains compact, but the user must move their hand or rotate the handgun to actuate the release, causing loss of control

Engineering Contradiction:
Improveslim-profile designVSAvoidcontrol over handgun direction
Core Design Contradiction:
ShapeVSReliability

Solution Approach 1:

The magazine release mechanism is segmented into distinct functional components: a stationary contact surface on the handgun body and a movable button element. This segmentation allows the button to be actuated by simple linear finger pressure without requiring hand movement or handgun rotation, thereby maintaining control over the weapon's direction while preserving the compact slim-profile design.

Inventive Principle:
Principle #1Segmentation

3Shape

If the magazine release contact surface is made flush with the receiver surface, then the profile is streamlined, but the force and direction of motion required become counter-intuitive and restrictive

Engineering Contradiction:
Improveflush contact surfaceVSAvoidforce and motion requirements
Core Design Contradiction:
ShapeVSEase of operation

Solution Approach 1:

The contact surface of the magazine release button features a localized ergonomic design with specific curvature and texture characteristics that differ from the surrounding flush surface. This local quality enhancement allows the button to be actuated by natural finger motion while the overall surface remains flush with the receiver, maintaining the streamlined profile without compromising ease of operation.

Inventive Principle:
Principle #3Local quality

AI summary

A magazine release assembly includes a first component. The first component includes at least one interlocking protrusion of an interlocking assembly and a button with a sloped surface. The first component is insertable into a first opening within a receiver frame of a handgun. The magazine release assembly includes an additional component. The additional component includes at least one interlocking recess of the interlocking assembly and a catch spring slot. The additional component is insertable into an additional opening with the receiver frame of the handgun. The at least one interlocking recess is configured to rotatably couple with the at least one interlocking protrusion within the receiver frame. The catch spring slot is configured to receive a catch spring following the rotatable coupling of the at least one interlocking recess and the at least one interlocking protrusion.
