Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current ejection port covers for firearms are cumbersome to assemble and dismantle, requiring professional expertise and significant time and effort, making them inefficient for quick changes between right and left-side shell ejection.
Innovation Solution
A slideable ejection port cover with a shutter operatively connected to a locking component, featuring a spring mechanism that allows for reversible transformation between open and closed configurations, enabling easy switching between right and left-side shell ejection and incorporating securing screws for adjustable positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If traditional ejection port covers are used, then the ejection port is covered to prevent dust and debris entry, but the covers are cumbersome to assemble and dismantle requiring professional work and massive time and effort
Solution Approach 1:
The ejection port cover is divided into separate components including a cover body, locking component, and spring mechanism, allowing independent manipulation of each part for rapid assembly and disassembly without requiring professional expertise
Solution Approach 2:
The cover transitions from a static traditional design to a dynamic system with movable components that can be quickly positioned between locked and unlocked states, enabling rapid configuration changes between right and left ejection modes
2Object-affected harmful factors
If traditional ejection port covers are used, then the ejection port is covered to prevent dust and debris entry, but the covers require the work of a professional for assembly and dismantling
Solution Approach 1:
The cover incorporates self-contained locking and unlocking mechanisms that allow the user to perform assembly and disassembly operations independently without requiring professional expertise or specialized tools
Solution Approach 2:
The spring-loaded locking component acts as an intermediary mechanism that simplifies the interaction between the user and the cover, providing intuitive engagement and disengagement through a single manual operation
3Productivity
If a slideable ejection port cover with spring mechanism is used, then quick opening and closing is enabled for easy switching between right and left-side shell ejection, but the device complexity increases with locking component and spring
Solution Approach 1:
Multiple functions (covering, locking, unlocking, and spring-loaded return) are merged into a single integrated cover assembly, reducing the number of separate components and simplifying the overall device structure despite the enhanced functionality
4Adaptability or versatility
If a slideable ejection port cover is used, then reversible transformation between open and closed configurations is enabled, but the device requires additional components for securing and locking
Solution Approach 1:
The cover assembly serves multiple functions simultaneously: it acts as a protective cover, a locking mechanism, and a configurable component for both right and left ejection modes, reducing the need for separate specialized components
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 provides a quick and efficient method for switching ejection ports, preventing dust and debris entry while allowing for reversible transformation, enhancing user convenience and operational efficiency.
Implementation Method 1
the locking component comprises a spring configured, at such times as the slideable ejection port cover is in use in the receiver and the ejection port cover is in the closed configuration, to hold the locking component in a pressure-applying mode against the receiver
Implementation Method 2
the locking component configured to compress the spring when pulled manually away from the receiver, thereby enabling reversible transformation of the ejection port cover from the closed configuration to the open configuration
Data Source
AI summary
A slideable ejection port cover having at least two configurations, an open configuration in which shell ejection via the ejection port is enabled, and a closed configuration in which the ejection port is substantially immovably covered; the ejection port cover comprising a shutter operatively connected to a locking component, the shutter slideable along a longitudinal axis of the receiver; wherein the locking component comprises a spring configured, at such times as the ejection port cover is in the closed configuration, to hold the locking component in a pressure-applying mode against the receiver, the pressure-applying mode being a default mode, thereby immobilizing the shutter relative to the receiver, and the locking component configured to compress the spring when pulled manually away from the receiver, thereby enabling reversible transformation of the ejection port cover from the closed configuration to the open configuration.
