Modular Handgun Receiver Assembly With Detachable Grip Locking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing handguns have difficulty in adapting to users of varying hand sizes, with complex structures and large vertical extents that hinder ease of use and transport.
Innovation Solution
A receiver assembly comprising an upper and lower receiver portion with a locking mechanism, including a locking element that allows for easy detachment and rigid coupling, and a design that minimizes vertical extent when dismantled.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a complex attachment element is used to secure the grip to the receiver, then the grip can be firmly fixed, but the attachment element becomes difficult to remove and the receiver maintains a large vertical extent
Solution Approach 1:
The receiver is divided into an upper receiver portion and a lower receiver portion that can be detached from each other. The lower receiver portion includes a receiving space that can accommodate a grip module, allowing the grip to be easily attached and removed without complex attachment elements remaining on the receiver.
Solution Approach 2:
The grip module is extracted as a separate component that can be inserted into and removed from the receiving space in the lower receiver portion. This allows the grip to be easily attached and detached without leaving complex attachment elements on the receiver, solving the contradiction between firm fixation and ease of removal.
2Adaptability or versatility
If a complex carrier element is used to allow adaptation to diverse shooter requirements, then adaptability is improved, but the weight of the handgun increases
Solution Approach 1:
The receiver is segmented into upper and lower portions, with the lower portion containing a receiving space for interchangeable grip modules. This segmentation allows different grip modules to be attached to the same receiver, providing adaptability to diverse shooter requirements without requiring a complex carrier element throughout the entire receiver structure.
Solution Approach 2:
The lower receiver portion with its receiving space serves as a universal base that can accommodate multiple different grip modules. This multi-functionality allows a single receiver design to adapt to diverse shooter requirements by simply changing the grip module, without increasing the weight through complex carrier elements.
3Adaptability or versatility
If the receiver is designed with large vertical extension to accommodate attachment elements, then the structure can support various components, but the handgun takes up too much space when dismantled for transport
Solution Approach 1:
The receiver is divided into upper and lower portions, allowing the grip module to be detached from the receiver. When dismantled, only the upper receiver portion remains with its original compact dimensions, while the grip module can be separately stored or transported, significantly reducing the overall vertical extent for transport purposes.
Solution Approach 2:
The grip module is extracted as a separate removable component from the receiver. This extraction allows the receiver to maintain its compact vertical extent when the grip is removed, while still providing accommodation for the grip when needed, thus resolving the contradiction between component accommodation and compact size for transport.

AI summary
A receiver assembly for a handgun. The receiver assembly includes an upper receiver portion, a lower receiver portion, and a locking mechanism. The upper receiver portion includes i) a guide rail for receiving a slide assembly and ii) a magazine compartment for receiving a magazine. The magazine compartment defines a magazine insertion direction, and the magazine is pushable into the magazine compartment in the magazine insertion direction. The lower receiver portion is slidable onto the upper receiver portion in the magazine insertion direction. The locking mechanism is configured to couple the lower receiver portion to the upper receiver portion. The locking mechanism includes a locking element that is structurally independent. The locking element includes a contact projection and a locking projection. The contact projection form-fittingly engages with the lower receiver portion and the locking projection form-fittingly engages with the upper receiver portion.
