Modular Firearm Grip With Interchangeable Shells
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional firearm grips, especially those made of steel, can be bulky and inflexible, making them unsuitable for users with smaller hands, while plastic grips lack stability and can be damaged during use without proper grip shells, limiting their applicability and comfort.
Innovation Solution
The design of modular and adjustable grip systems with replaceable grip shells and backs made from varying materials, including plastic and fiberglass, which can be customized to fit different hand sizes and provide improved stability and comfort through die-casting and snap-in attachment mechanisms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If steel grip pieces are used, then stability and firmness are improved, but weight and bulkiness increase
Solution Approach 1:
The patent employs composite materials by combining a plastic grip piece with metal reinforcement elements (such as steel bars or inserts) integrated into the plastic structure. This allows the grip to achieve the stability and firmness of steel while maintaining the weight advantages of plastic, effectively resolving the contradiction between stability and weight.
2Adaptability or versatility
If plastic grip shells are made separate from grip piece, then adaptability to different hand sizes is improved, but structural integrity and stability decrease
Solution Approach 1:
The grip system is segmented into separate components: a plastic grip piece and removable plastic grip shells. The grip piece contains integrated metal reinforcement bars that provide structural stability, while the detachable grip shells allow users to exchange different sized shells to adapt to various hand sizes. This segmentation enables both adaptability and structural integrity.
3Ease of manufacture
If conventional plastic grip pieces are designed as one size fits all, then manufacturing simplicity is improved, but usability for different hand sizes deteriorates
Solution Approach 1:
The grip system divides the grip into a standardized grip piece (easy to manufacture with integrated metal bars) and interchangeable grip shells (available in different sizes). This allows the main grip piece to be produced efficiently through injection molding while providing customization options for user comfort, resolving the contradiction between manufacturing simplicity and ease of operation.
4Shape
If wooden grip shells are used, then traditional craftsmanship and appearance are improved, but availability and consistency deteriorate
Solution Approach 1:
The patent replaces traditional wooden grip shells with plastic grip shells that can be mass-produced through injection molding. These plastic shells offer consistent dimensions, reliable fit, and uniform appearance across production batches, eliminating the variability and availability issues associated with natural wood while maintaining the desired aesthetic appearance.

AI summary
A firearm grip, a firearm grip construction set and related methods are disclosed. An example firearm grip includes a grip portion, which includes a wall covering at least a portion of a magazine and a plurality of ribs. The firearm grip also has a first grip shell having a plurality of first lateral edges, second grip shell having a plurality of second lateral edges, and a grip back having a top edge and a bottom edge. With the example firearm grip, at least one of the first grip shell or the second grip shell is exchangeable. In addition, at least one of the first grip shell, the second grip shell or the grip back is coupled to the grip portion with an undercut tongue and groove connection. Further, at least one of the first lateral edges, the second lateral edges, the top edge or the bottom edge slidably engages under one of the plurality of ribs and an opposite edge of at least one of the first lateral edges, the second lateral edges, the top edge or the bottom edge is coupled to the grip portion via an attachment. In addition, the grip back of the example firearm grip slidably engages at least one of the first lateral edges or the second lateral edges and holds at least one of the first grip shell or the second grip shell in place.
