Break-Barrel Firearm Control Layout for Single-Gesture Opening
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing break-barrel firearms require separate operations for securing and opening, which can be cumbersome and less ergonomic.
Innovation Solution
A break-barrel firearm design with a single actuation element that integrates safety and closing functions, allowing simultaneous operation through a single gesture, utilizing a slider mechanism and lever system to control the barrel group's tilt and trigger mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If separate mechanical control elements are provided for safety and opening operations, then the firearm maintains clear functional separation and control, but the ease of operation deteriorates due to requiring multiple distinct gestures
Solution Approach 1:
The patent combines the safety control function and opening control function into a single actuation element. This element can be positioned in different positions (first position for safety, second position for opening) to perform multiple functions. By merging these controls, the patent reduces the number of separate gestures required while maintaining clear functional separation through positional differentiation.
Solution Approach 2:
The single actuation element is designed to perform multiple functions: controlling safety engagement/disengagement and controlling the opening operation. This multi-functional element replaces what were previously separate control mechanisms, allowing the user to access different functions by positioning the same element differently, thereby improving ease of operation without significantly increasing device complexity.
2Productivity
If multiple separate operations are required for securing and opening, then functional control is precise and distinct, but the time required for operations increases
Solution Approach 1:
By merging safety control and opening control into a single actuation element with multiple positions, the patent allows users to perform securing and opening operations more quickly. Instead of requiring separate gestures for each function, the user can transition between functions by moving the single element to different positions, reducing the total time required for these operations.
3Ease of operation
If a single actuation element is used for both safety and opening controls, then the ease of operation improves through reduced interfaces, but the reliability may deteriorate due to increased functional integration
Solution Approach 1:
While using a single actuation element, the patent maintains functional reliability by segmenting the control logic into distinct positions. The element has a first position for safety control and a second position for opening control, ensuring that each function has a dedicated, unambiguous control state. This positional segmentation prevents functional confusion while maintaining the benefits of a reduced interface count.
Solution Approach 2:
The actuation element serves as an intermediary that mediates between the user and multiple functions. By providing distinct positions for different functions, it acts as a mediator that prevents direct conflict between safety and opening controls, maintaining reliability while simplifying the interface.

AI summary
The present invention concerns a firearm comprising at least one frame and a barrel group comprising at least one barrel, the barrel group being mounted in a sliding manner with respect to the frame, wherein the frame houses at least one trigger device configured to trigger the firing of an ammunition, a safety device configured to act on the trigger device so as to selectively disengage it, and a closing device configured to act between the frame and the barrel group so as to prevent the barrel group from tilting with respect to the frame, and is characterized in that it comprises an actuation element configured to selectively activate the safety device and the closing device.
