Solution Overview

Problem

Current weapon safety designs fail to provide quick and easy access to loading and unloading components while preventing accidental discharges, often requiring complex setups or immobilizing triggers, which can hinder the loading and unloading process.

Innovation Solution

A sleeve apparatus that slides over the trigger and handle portions of a gun, allowing access to loading and unloading components while preventing trigger access, enabling safe and efficient loading and unloading without significant delay.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If complex trigger guard designs with multiple parts, fasteners, and locking mechanisms are used to prevent accidental discharges, then trigger immobilization is improved, but device complexity and application time increase

Engineering Contradiction:
Improvetrigger immobilizationVSAvoiddevice complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The trigger guard is divided into a first portion and a second portion that can be separately positioned and then connected together. This segmentation allows each portion to be independently manipulated during application, simplifying the overall process while maintaining secure trigger immobilization through the connection mechanism.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

A connection mechanism acts as an intermediary element between the first and second portions of the trigger guard. This intermediary component facilitates easy assembly and secure locking of the two portions together, enabling reliable trigger immobilization without requiring complex multi-step fastening procedures.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If trigger guard designs require precise alignment of apertures, fasteners, and washers to lock the trigger, then trigger immobilization is improved, but ease of operation and application speed deteriorate

Engineering Contradiction:
Improvetrigger immobilizationVSAvoidease of application
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

By segmenting the trigger guard into two portions with integrated connection mechanisms, the design eliminates the need for precise alignment of multiple separate components. Each portion can be independently positioned on the trigger, and the connection mechanism automatically secures them together without requiring exact alignment, significantly improving ease of application.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The connection mechanism is designed to automatically engage and secure the first and second portions together once positioned near the trigger. This self-service feature eliminates the need for users to manually align multiple components, as the mechanism itself facilitates the connection process, making application quick and intuitive.

Inventive Principle:
Principle #25Self-service

3Reliability

If child-proof locking mechanisms requiring household tools are used to prevent unauthorized access, then security against unauthorized use is improved, but productivity and quick access capability deteriorate

Engineering Contradiction:
Improvesecurity against unauthorized accessVSAvoidloading and unloading speed
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The trigger guard incorporates dynamic characteristics by allowing easy application and removal by the authorized user through simple manual manipulation, while maintaining static security features that prevent unauthorized access without tools. This dynamic design enables quick transitions between secure and accessible states, supporting both security and productivity requirements.

Inventive Principle:
Principle #15Dynamics

AI summary

A weapon safety apparatus comprising a sleeve comprising a cavity portion open to receive a trigger portion of a weapon and free of any structures that impede movement of the trigger. The sleeve further comprises a body portion comprising at least one closed portion preventing access to a trigger of the weapon. The sleeve is shaped to provide access to all loading or unloading components of the weapon. The cavity portion of the sleeve may be further open to receive a handle of the weapon. A method for loading and unloading a weapon using the above weapon safety apparatuses is also provided.
