Firearm Barrel Cover with Elastic Trigger Guard Attachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Firearms, especially those stored with the barrel facing up, are prone to dust, debris, and free air exposure, which can affect their mechanics and lubrication, leading to increased maintenance needs and potential accidental firing risks.
Innovation Solution
A protective device comprising a trigger cover clipped onto the trigger guard and elastic connective members attaching to both the trigger cover and a waterproof barrel cover, which fits over the barrel end, reducing exposure to dust, debris, and air while being quickly removable for use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the firearm is stored with the barrel facing up for easy access, then the firearm is readily available for use, but dust and debris can enter the barrel affecting the mechanics
Solution Approach 1:
The protective cover is pre-positioned on the firearm before storage, creating a barrier against dust and debris in advance. The cover remains in place during storage but can be quickly removed when the firearm is needed, thus preventing contamination while maintaining readiness.
Solution Approach 2:
The protective cover acts as an intermediary barrier between the firearm barrel and the external environment. It physically separates the internal mechanics from dust and debris in the storage environment, allowing the firearm to be stored barrel-up without contamination risks.
2Ease of operation
If the firearm is stored without protection, then access is quick and easy, but free air enters the barrel and dries out the lubrication
Solution Approach 1:
The protective cover is installed beforehand to seal the barrel, preventing free air from entering and drying out the lubrication during storage. When needed, the cover is simply removed, maintaining both lubrication integrity and quick access.
Solution Approach 2:
The protective cover serves as an intermediary that controls the interface between the firearm's internal lubricated surfaces and the external air. It prevents direct exposure to free air that would cause lubrication drying, while allowing quick access when removed.
3Object-affected harmful factors
If a protective cover is added to the firearm, then protection from dust and debris is improved, but the device complexity increases
Solution Approach 1:
The protective cover is made from a flexible, thin material that can easily conform to the barrel shape and be stored when not in use. This simple flexible barrier provides effective protection against dust and debris without adding significant complexity or bulk to the firearm system.
Solution Approach 2:
The protective system is segmented into a simple, separate cover component that can be independently attached and removed. This segmentation allows the protection function to be added without permanently modifying the firearm, maintaining simplicity while providing effective contamination protection.
4Object-affected harmful factors
If the protective device is designed to be secure, then protection is maintained, but removal time increases
Solution Approach 1:
The protective cover incorporates elastic connective members that provide dynamic attachment - secure enough to maintain protection during storage, but flexible enough to allow quick removal when needed. The elastic properties enable the cover to snap into place securely yet be easily pulled off.
Solution Approach 2:
The attachment mechanism uses elastic connective members that change their physical state between a constrained, secure position during storage and a released, removable position when needed. This parameter change allows the same mechanism to provide both secure protection and quick access.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution effectively reduces the need for frequent cleaning, maintains lubrication, and minimizes accidental firing risks by protecting the trigger and barrel from environmental contaminants while allowing rapid deployment of the firearm.
Implementation Method 1
at least one elastic connective member that attaches to the trigger guard... The elastic nature of the connective members hold the trigger cover and barrel cover onto the firearm

AI summary
A firearm barrel and internals saver keeps debris, foreign objects, and free air out of a firearm. The trigger cover may be clipped on to the trigger guard of a firearm. An elastic connective member has a barrel cover at the opposite end, which fits over and covers the opening of the barrel of the firearm. Both the firearm barrel cover and internals saver are quickly removable for use in the field.
