Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Current shell collectors are either too bulky, costly, or require both hands for assembly, adding weight to firearms and making it difficult for solo users to efficiently collect and store spent shell casings without compromising firearm operation.

Innovation Solution

A lightweight, portable shell casing receiver with a horseshoe-shaped member and extending arm, adaptable to any firearm, which secures via terminal ends and allows for easy attachment of a catching device like a bag or hat, using a universal rail system compatibility.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If a sweeper-style brass collector is used, then shell collection capability is improved, but the device becomes bulky and expensive

Engineering Contradiction:

Improveshell collection capabilityVSAvoiddevice size

Core Design Contradiction:

ProductivityVSVolume of moving object

Solution Approach 1:

The patent extracts the essential function of shell collection from the bulky sweeper mechanism, retaining only the critical components needed for collection while eliminating unnecessary bulk, resulting in a compact receiver that maintains collection effectiveness

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The patent creates a simplified version of the sweeper collector by copying only the essential functional elements and adapting them to a compact receiver design, achieving collection capability without the bulk of the original sweeper mechanism

Inventive Principle:

Principle #26Copying

2Weight of moving object

If a reversible attachment bag collector is used, then portability is improved, but assembly requires both hands and adds weight to the firearm

Engineering Contradiction:

Improvefirearm weightVSAvoidassembly ease

Core Design Contradiction:

Weight of moving objectVSEase of operation

Solution Approach 1:

The patent merges the collection bag and receiver into a single integrated unit, eliminating the need for separate attachment operations and allowing solo assembly while reducing overall weight compared to separate components

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The receiver is designed with universal compatibility features that allow it to attach to various firearm types using standard rails, eliminating the need for firearm-specific adaptations and enabling easy assembly by one person

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Adaptability or versatility

If a reversible attachment bag collector is used, then portability is improved, but it adds weight to the firearm

Engineering Contradiction:

ImproveportabilityVSAvoidfirearm weight

Core Design Contradiction:

Adaptability or versatilityVSWeight of moving object

Solution Approach 1:

The patent uses a flexible bag material that can be collapsed when not in use, minimizing the added weight and bulk, while still providing adequate collection capacity when needed

Inventive Principle:

Principle #30Flexible shells and thin films
