Solution Overview

Problem

Shotgun users face inconvenience when needing to switch between different shotgun chokes for varying shooting distances, as they often require multiple chokes and must search through their pockets to find the correct one.

Innovation Solution

A magazine cap choke adapter that allows an extra choke to be stored in place of the shotgun magazine cap, featuring a body with threaded ends for secure attachment and an optional strap attachment loop for easy carrying.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If multiple chokes are stored separately in pockets, then the user has access to different choke types, but the user must search through pockets to find the correct choke

Engineering Contradiction:
Improveease of accessing chokeVSAvoidtime to find correct choke
Core Design Contradiction:
Ease of operationVSLoss of time

Solution Approach 1:

The magazine cap adapter merges the storage function with the choke function by integrating a choke into the magazine cap assembly. The adapter body threads onto the magazine tube and provides both magazine cap functionality and choke functionality, allowing the user to access the choke directly from the shotgun without separate pocket storage

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The magazine cap adapter serves multiple functions: it acts as both a magazine cap closure and a choke device. The adapter body with its threaded distal end can accept different choke types, making it a universal solution that combines storage, closure, and shot distribution control in a single component

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Productivity

If a choke is stored on the shotgun, then the user can quickly access the choke, but the shotgun structure becomes more complex

Engineering Contradiction:
Improvespeed of choke switchingVSAvoidshotgun structure complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The magazine cap adapter combines multiple functions into a single component: it serves as the magazine cap closure, the choke device, and the mounting interface. This multi-functionality reduces the need for separate components while enabling quick choke access and switching

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The adapter is designed as a separable component that can be independently attached to or removed from the magazine tube. This segmentation allows the choke functionality to be added or removed without permanently modifying the shotgun structure, maintaining simplicity while enabling quick switching

Inventive Principle:
Principle #1Segmentation

AI summary

The disclosed magazine cap choke adapter allows a user to store an extra choke in place of the shotgun magazine cap. The magazine cap choke adapter is formed from a body that includes a first female threaded end, or proximal end, that threads onto the magazine adapter of the shotgun. Moving away from the proximal end, the magazine cap choke adapter tapers to a second female threaded end, or distal end, into which a choke is optionally threaded.
