Modular Foregrip With Interchangeable Angled Attachments
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional foregrips with fixed configurations can cause unnatural ulnar deviation and compromise the grip and stability of small arms weapons when the support arm cannot be fully extended, leading to reduced effectiveness in shooting and manipulation.
Innovation Solution
A modular foregrip design with interchangeable grip angle components and an integral forward extending switch platform that allows the user to maintain a positive thumb-forward grip, incorporating a grip base and detachable electronic head for integrated illumination and targeting systems, adaptable to various rail interface systems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a fixed configuration foregrip is used, then the structure is simple and easy to manufacture, but the grip angle cannot be adjusted causing unnatural ulnar deviation when the support arm cannot be fully extended
Solution Approach 1:
The foregrip is divided into multiple segments: a grip base and interchangeable grip attachments with different grip angles. This segmentation allows the user to select and attach different grip angle components based on their specific needs, resolving the contradiction between operational comfort and structural simplicity by making the structure modular rather than fixed.
Solution Approach 2:
The foregrip transitions from a static, fixed configuration to a dynamic, adjustable configuration. The interchangeable grip attachments enable the grip angle to be changed according to the user's support arm extension capability, allowing the device to adapt to different operational conditions and user anatomies.
2Adaptability or versatility
If a fixed angle grip attachment is used, then the manufacturing is simple, but the adaptability to different users and weapon configurations is limited
Solution Approach 1:
The grip base is designed as a universal platform that can accommodate multiple types of grip attachments with different angles. This multi-functionality allows a single base unit to serve multiple users and weapon configurations by simply changing the attachment component, thereby achieving adaptability without proportionally increasing manufacturing complexity.
Solution Approach 2:
The invention changes the grip angle parameter by providing attachments with different angular configurations. Instead of manufacturing a completely different foregrip for each angle, the patent varies only the angular parameter of the attachment component while maintaining compatibility with the standard grip base, thus achieving adaptability with controlled manufacturing complexity.
3Ease of operation
If the foregrip is positioned forward on the handguard, then the thumb-forward grip is supported, but the support arm must be fully extended which causes unnatural ulnar deviation when it cannot be extended
Solution Approach 1:
By segmenting the grip into a base and interchangeable angle attachments, the invention allows adjustment of the effective grip position and angle. This enables users with varying support arm lengths to achieve a proper thumb-forward grip without forcing their arm into an extended position that would cause ulnar deviation.
Solution Approach 2:
The invention changes the grip angle parameter to accommodate different support arm lengths. Users can select attachments with appropriate angles that allow their specific arm length to achieve a natural, comfortable thumb-forward grip position without excessive extension or ulnar deviation.

AI summary
The weapon foregrip uses a modular design that includes a grip base and interchangeable angled grip attachments. The interchangeable angle grip attachments have bottom grip faces with differing grip angles, which allows the configuration of the foregrip to be selectively adapted for the particular user and weapon. The grip base has a grip body and an integral forward extending switch platform, which properly positions a pressure switch under the user's thumb so that an illumination and/or targeting device can be actuated by the user's thumb while maintaining a positive “thumb-forward” grip on the weapon. The foregrip may also have an electronics head, which houses integrated electronic illumination and/or targeting systems.
