Modular Firearm Trigger Shoe Swapping Without Pistol Disassembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing 1911/2011 pistols require complete disassembly to change the trigger shoe, which is inconvenient for users who want to switch between different trigger shoes during shooting exercises.
Innovation Solution
A detachable trigger shoe system that allows the trigger shoe to be swapped without disassembling the pistol, utilizing a selectable detachment feature between the trigger shoe and trigger bow.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the trigger shoe is permanently attached to the trigger bow, then the structural strength and reliability are improved, but the ease of operation deteriorates because complete disassembly is required to change trigger shoes
Solution Approach 1:
The trigger assembly is segmented into detachable components (trigger shoe, trigger bow, and intermediate component) that can be separated and reattached. The trigger shoe can be removed from the trigger bow through a selective detachment mechanism, allowing users to swap trigger shoes without removing the entire trigger assembly from the firearm frame.
Solution Approach 2:
The connection between the trigger shoe and trigger bow is made dynamic rather than static. The selectable detachment feature allows the connection to transition between engaged and disengaged states, enabling easy replacement of trigger shoes while maintaining structural integrity during normal operation.
2Adaptability or versatility
If the trigger assembly is completely disassembled to change trigger shoes, then the adaptability is improved, but the loss of time increases due to complete disassembly and reassembly procedures
Solution Approach 1:
The trigger assembly is divided into modular components that can be independently replaced. The trigger shoe is separated from the trigger bow through an intermediate component, allowing users to quickly swap trigger shoes without disassembling the entire trigger assembly or removing the trigger bow from the frame.
Solution Approach 2:
The trigger bow remains pre-installed in the firearm frame, and the trigger shoe can be pre-prepared for replacement. The selective detachment mechanism allows the trigger shoe to be quickly removed and replaced without requiring preliminary disassembly of the trigger assembly, significantly reducing replacement time.
3Ease of operation
If a detachable trigger shoe system is implemented, then the ease of operation is improved for trigger shoe replacement, but the device complexity increases due to additional detachment features
Solution Approach 1:
An intermediate component is introduced between the trigger shoe and trigger bow to enable selective detachment. This intermediate component provides the detachment mechanism that allows the trigger shoe to be removed from the trigger bow without requiring complex tools or procedures, while adding minimal complexity to the overall system.
Data Source
AI summary
A trigger system having a detachable trigger shoe. The trigger shoe is made detachable from the trigger bow while the trigger bow remains in an installed state within the pistol. A selectable detachment feature is provided for the connection between the trigger shoe and the trigger bow. The user can activate this detachment feature and remove the shoe while leaving the trigger bow in place. The user can then install a different trigger shoe while the trigger bow remains in place.
