Modular Firearm Handgrip Sleeve and Backstrap for Full-Side Ergonomics
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Prior art firearm grips with backstraps fail to provide customizable ergonomic adjustments on all sides of the handgrip, cannot accommodate magwell features, and require irreversible modifications to enhance friction and fit, which can damage the firearm and reduce resale value.
Innovation Solution
A modular handgrip assembly comprising a flexible grip sleeve and interlocking backstrap that envelops the handgrip on all sides, allowing reversible texture and form modifications, and includes a magwell for improved reloading, secured without screws or fasteners.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If prior art backstraps are used to provide grip customization, then lateral distance adjustment between front strap and backstrap is achieved, but the backstrap cannot exceed frame thickness and cannot fill the sides of the grip
Solution Approach 1:
The grip customization system is divided into separate modular components: a backstrap module and side fill modules. The backstrap adjusts lateral distance while side fill modules independently extend coverage to the sides of the grip, allowing each component to optimize its specific function without compromising the other.
Solution Approach 2:
The invention extends grip customization from one dimension (lateral distance adjustment via backstrap thickness) to multiple dimensions by adding side fill modules that extend in the lateral direction toward the sides of the grip, thereby increasing both longitudinal and lateral coverage area.
2Length of moving object
If prior art backstraps are used, then some lateral adjustment is possible, but form and texture modifications on palm regions cannot be made
Solution Approach 1:
Different modules of the grip customization system are assigned different specialized functions: the backstrap module handles lateral distance adjustment with its thickness variations, while the side fill modules provide form and texture modifications on the palm regions. This local specialization allows each component to optimize its specific customization capability.
Solution Approach 2:
The side fill modules serve multiple functions: they extend lateral coverage to fill the sides of the grip, provide form customization through various shapes, and enable texture modifications on palm regions. This multi-functionality addresses multiple customization needs simultaneously.
3Reliability
If irreversible modifications like stippling or epoxy putty are applied to gun frames, then additional friction and fit are attained, but resale value is greatly reduced and damage risk increases
Solution Approach 1:
The side fill modules act as intermediary components between the grip frame and the user's hand. Instead of directly modifying the firearm frame with irreversible treatments, these removable modules provide the necessary friction and fit enhancement, thereby protecting the original firearm surface from damage while achieving the same ergonomic benefits.
Solution Approach 2:
The invention changes the approach from permanently altering the firearm's physical parameters (through stippling or epoxy) to using removable modules with varied surface parameters. These modules can be manufactured with different friction characteristics and textures, allowing parameter optimization without permanent modification to the firearm itself.
4Ease of operation
If prior art backstraps are used, then basic backstrap function is provided, but magwell accommodation is not possible
Solution Approach 1:
The grip system is segmented into independent modules including the backstrap and side fill modules. The side fill modules can be specifically designed with magwell cavities to accommodate magazine wells, while the backstrap module maintains its simple installation function. This segmentation allows magwell integration without complicating the backstrap installation process.
Solution Approach 2:
The side fill modules are designed to perform multiple functions: they extend lateral grip coverage, provide texture modifications on palm regions, and accommodate magwells through integrated cavities. This multi-functionality enables magwell integration while maintaining the simplicity of backstrap installation through modular design.

AI summary
The present invention, a handgrip assembly, generally relates to firearms that have a handgrip and a backstrap thereon. The present invention comprises an interlocking backstrap, which replaces the prior art backstrap of a handgrip; and a fully enveloping grip sleeve, which enables form and texture modifications on all sides of the handgrip of the firearm. The present invention can be restrained on the frame of the gun across all degrees of freedom without the use of screws or extraneous fasteners.
