Solution Overview

Problem

Modular grip assemblies in firearms experience loosening due to recoil forces, leading to undesirable play and discontinuities in the grip surface, affecting grip effectiveness, comfort, and aesthetic design, especially when using rotatably-driven fasteners.

Innovation Solution

A grip assembly design that uses a push tool access port and a canted retention system with a plunger assembly to securely attach grip parts like backstraps and magwells without fastener discontinuities, allowing easy removal and replacement of grip accessories using a push tool and a spring mechanism.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If rotatably-driven fasteners are used to attach grip parts, then the grip assembly can be assembled and disassembled, but the fasteners loosen due to recoil forces causing play and discontinuities

Engineering Contradiction:

Improveassembly and disassembly capabilityVSAvoidfastener retention under recoil

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The grip assembly is divided into modular components (grip frame, backstrap, magwell) that can be independently attached and detached. Each component has its own attachment interface, allowing selective assembly and disassembly without affecting the entire grip assembly, thereby maintaining ease of operation while improving reliability through localized secure connections.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The retention system uses a dynamic plunger assembly that can move between engaged and disengaged positions. The plunger is spring-biased to automatically maintain engagement under varying recoil forces, adapting the retention mechanism to dynamic loading conditions and preventing fastener loosening while preserving easy assembly/disassembly capability.

Inventive Principle:

Principle #15Dynamics

2Strength

If rotatably-driven fasteners are used, then grip parts can be secured, but fastener discontinuities affect grip surface aesthetics and comfort

Engineering Contradiction:

Improvegrip part securementVSAvoidgrip surface continuity

Core Design Contradiction:

StrengthVSShape

Solution Approach 1:

The fastener mechanism is extracted from the visible grip surface and relocated to hidden locations. The plunger assembly is positioned within recesses or internal cavities of the grip components, with only minimal external features (such as small access ports or subtle indicators) visible on the grip surface. This maintains the securement function while eliminating aesthetic and comfort disruptions caused by exposed fasteners.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The fastening mechanism is nested within the grip component structure itself. The plunger assembly is housed inside the grip frame or backstrap, with the retention features integrated into the internal geometry of the components. This nesting approach allows the fastening function to be embedded within the overall grip structure, preserving surface continuity and aesthetic appearance while maintaining secure attachment.

Inventive Principle:

Principle #7Nested doll (Nesting)

3Adaptability or versatility

If modular grip assembly is used, then grip customization is enabled, but recoil forces cause loosening and play

Engineering Contradiction:

Improvegrip customization capabilityVSAvoidgrip assembly stability under recoil

Core Design Contradiction:

Adaptability or versatilityVSStability of the object's composition

Solution Approach 1:

The modular grip assembly is segmented into standardized components with compatible attachment interfaces. Each grip component (backstrap, magwell, inserts) can be independently selected and attached to the grip frame, enabling extensive customization. The segmentation allows users to mix and match components while maintaining stable, recoil-resistant connections through the standardized plunger-based retention system.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The attachment interface design provides universal compatibility across different grip components. The same plunger-based retention mechanism and interface geometry are used for all modular components, allowing a single retention system design to serve multiple customization scenarios. This universality enables grip customization while ensuring consistent stability and recoil resistance across all component combinations.

Inventive Principle:

Principle #6Universality (Multi-functionality)
