Chamber Safety Device with High-Visibility Color for Shotgun Loading Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional autoloaders and semi-automatic shotguns pose safety concerns as it is difficult to visually confirm whether they are loaded and capable of firing, leading to restrictions in public shooting locations, as they do not break open like traditional models, making it hard to ensure the weapon is unloaded and safe.
Innovation Solution
A chamber safety device with a snug friction fit design and high visibility coloration that prevents the weapon from being fired and provides a visual indicator of its empty status, suitable for both autoloaders and break-action shotguns, using materials like silicone or hard plastic, with a bulbous shape for easy handling and lubricant retention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional autoloaders and semi-automatic shotguns are used, then the weapon functionality and reduced recoil are improved, but the visual safety indication capability deteriorates
Solution Approach 1:
The patent applies color changes by using a brightly colored (e.g., orange or red) safety plug that is visible when inserted into the chamber. This color contrast provides immediate visual indication that the chamber is blocked and the weapon cannot fire, resolving the contradiction between maintaining weapon functionality and providing clear visual safety indication.
Solution Approach 2:
The safety plug acts as an intermediary object inserted into the chamber to block the firing path. This physical intermediary not only prevents firing but also serves as a visual indicator, simultaneously addressing both the safety indication problem and the weapon functionality requirement.
2Difficulty of detecting and measuring
If break-open position is used to indicate safety, then the visual safety indication is improved, but the adaptability to autoloader types deteriorates
Solution Approach 1:
The safety plug is designed as a universal solution that can be inserted into the chamber of various shotgun types including autoloaders, semi-automatics, and break-action models. This single device provides both the visual indication function and the chamber blocking function across multiple weapon platforms, resolving the contradiction between visual indication and adaptability.
Solution Approach 2:
The invention extracts the safety indication function from the weapon's mechanical operation (break-open position) and creates a separate, standalone safety plug device. This extracted device can be universally applied to different weapon types without requiring structural modifications, thereby achieving both clear visual indication and broad adaptability.
3Reliability
If chamber blocking device is inserted, then the safety assurance is improved, but the device complexity increases
Solution Approach 1:
The safety plug is designed with local quality variations: a tapered end for easy insertion into the chamber, a cylindrical body for blocking the firing path, and a colored exterior for visual indication. This localized differentiation of functions within a simple single-piece structure achieves high safety assurance without increasing overall device complexity.
Solution Approach 2:
The safety plug is designed as a simple, inexpensive, single-use or easily replaceable component. Its simplicity reduces device complexity while maintaining high reliability for safety assurance during temporary storage or transport situations.
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 device ensures the shotgun cannot be accidentally fired and provides a clear visual safety indicator, allowing its use in public locations while maintaining the firearm's functionality and safety, ensuring users and observers can confirm the weapon is not loaded.
Implementation Method 1
The lower portion is configured to make a snug friction fit inside an opening of a weapon

AI summary
A chamber safety device is configured to be inserted into one or more openings of a weapon, such as the loading/ejection port(s) or barrel of a shotgun, rifle or handgun. When the chamber safety device is inserted into the one or more opening(s), the weapon is not capable of firing and/or being loaded with ammunition due to the fact that no bullet or shell can be inserted into the firing chamber and/or the weapon firing mechanism cannot come in contact with a bullet or shell located in the firing chamber. At least a portion of the chamber safety device is designed to extend outwardly from breach of the weapon and is colored in a high visibility color such that those nearby can visually detect the presence of the chamber safety device inserted in a weapon.
