Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing firearm triggers face challenges in customization due to size constraints within the receiver and other components, which can compromise trigger weight, safety modifications, and trigger shoe shape.

Innovation Solution

A trigger assembly design that actuates along a parallel or substantially parallel axis to the barrel of the firearm, incorporating a trigger shoe, brace, joint, trigger hood, and trigger bar coupled together to facilitate movement and discharge.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If traditional trigger designs are used, then trigger weight and safety modifications can be optimized, but size constraints within the receiver limit customization options

Engineering Contradiction:

Improvecustomization optionsVSAvoidreceiver size constraints

Core Design Contradiction:

Adaptability or versatilityVSVolume of moving object

Solution Approach 1:

The trigger assembly is reconfigured to actuate along a parallel axis to the barrel rather than the traditional perpendicular arrangement. This dimensional change allows the trigger components to be arranged in a different spatial configuration that accommodates customization needs while fitting within the existing receiver volume constraints.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

2Ease of operation

If trigger components are customized for optimal performance, then other components within the firearm may interfere or reduce safety

Engineering Contradiction:

Improvetrigger performanceVSAvoidfirearm safety

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The trigger assembly is divided into separate functional components including a trigger shoe, trigger bar, and safety mechanism that can be independently adjusted and optimized. This segmentation allows each component to be customized for performance while maintaining proper spatial relationships that ensure safety.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The trigger bar acts as an intermediary component that transmits force from the trigger shoe to the firing mechanism while incorporating safety features. This intermediary structure allows optimization of trigger pull characteristics while maintaining safety through controlled force transmission pathways.

Inventive Principle:

Principle #24Intermediary (Mediator)
