Spade Grip Trigger Assembly for Mounted Firearm Handling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Firearms, such as rifles or light or medium machine gun-style firearms, are large, heavy, and unwieldy, making effective use difficult due to their significant size, weight, and shape, which complicates carrying, shouldering, and accurate firing.
Innovation Solution
A firearm spade grip assembly comprising a paddle trigger assembly and mounting system that allows for convenient actuation and firing by translating an actuator in an aft portion, with a paddle trigger safety to prevent accidental actuation, and a mounting system that enables the firearm to be coupled to a surface and pivot in various directions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a traditional firearm design is used, then the firearm structure is simple, but the firearm is large, heavy, and unwieldy making it difficult to carry, shoulder, and fire accurately
Solution Approach 1:
The firearm system is divided into separate functional modules: a traditional firearm (rifle or machine gun) mounted on a独立的 mounting system with spade grip and paddle trigger assembly. This segmentation allows the heavy firearm to be separated from the user's direct control, improving ease of handling while maintaining firing capability through the remote paddle trigger mechanism.
Solution Approach 2:
A mounting system with spade grip and paddle trigger assembly serves as an intermediary between the user and the traditional firearm. The mounting system includes a mounting base, support arm with joints, and trigger assembly that mediates the interaction between the user and the heavy firearm, allowing accurate aiming and firing without directly shouldering or gripping the weapon.
2Adaptability or versatility
If the firearm is mounted to a surface with pivot capability, then aiming flexibility is improved, but the mounting system complexity increases
Solution Approach 1:
The mounting system incorporates dynamic elements including a foundation joint allowing movement about a first pivot point and a mount joint allowing movement about a second pivot point. These dynamic joints enable the firearm to be positioned at various angles and orientations for flexible aiming while maintaining a stable mounted configuration during firing.
Solution Approach 2:
The mounting system adds spatial dimensions for aiming flexibility through the foundation joint and mount joint that enable movement in multiple directions. The spade grip and paddle trigger assembly extend the control interface into new spatial configurations, allowing the user to aim and fire from positions that would be impossible with traditional shouldered firearms.
3Reliability
If a paddle trigger assembly with safety is used, then accidental actuation is prevented, but the trigger assembly complexity increases
Solution Approach 1:
The paddle trigger assembly includes a safety mechanism that prevents actuation unless intentionally engaged. The paddle trigger requires deliberate user action to overcome the safety restraint, providing preliminary protection against accidental discharge while maintaining reliable firing capability when properly activated.
Solution Approach 2:
The paddle trigger assembly is designed to be self-regulating with inherent safety features that automatically prevent accidental actuation. The mechanism includes built-in restraint systems and engagement requirements that ensure only intentional user actions can trigger the firearm, eliminating the need for external safety devices or complex interlocking mechanisms.

AI summary
A firearm spade grip assembly can comprise a firearm, paddle trigger assembly, and/or a mounting system. A paddle trigger assembly can comprise a base spanning between and comprising a base forward end and a base aft end; a paddle trigger coupled to the base; a trigger actuator coupled to the base; and/or an actuator housing coupled to and extending forward from the base, wherein the trigger actuator is disposed at least partially within the actuator housing. Movement of the paddle trigger can be configured to translate the trigger actuator. A mounting system of a firearm spade grip assembly can comprise a mounting base configured to couple to a firearm receiver base or a firearm receiver of the firearm.
