Foldable Ground Blind Single Hub Assembly Design

Solution Overview

Problem

Existing ground blinds are not configured to allow hunters to effectively and safely hunt birds, lacking the necessary features for bird hunting such as secure gun storage and easy dog access.

Innovation Solution

A foldable ground blind design featuring a single hub assembly, triangular side walls, and apertures for gun rests, along with a dog door, which allows for easy setup and camouflage integration, utilizing a telescoping support system for stability and ease of transport.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Stability of the object's composition

If a traditional hub style ground blind with multiple hub assemblies is used, then structural stability is improved, but weight and assembly complexity increase

Engineering Contradiction:

Improvestructural stabilityVSAvoidblind weight

Core Design Contradiction:

Stability of the object's compositionVSWeight of moving object

Solution Approach 1:

The patent combines multiple hub assemblies into a single integrated hub assembly that supports multiple walls. The single hub assembly includes a central hub with multiple rods extending to support the front wall, first side wall, and second side wall, eliminating the need for separate hub assemblies at each corner and reducing overall weight while maintaining structural stability.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The single hub assembly serves multiple functions by supporting three different walls (front wall, first side wall, second side wall) from a single central structure. This multi-functional design reduces the number of components needed while providing the structural support that would traditionally require multiple separate hub assemblies.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Stability of the object's composition

If a traditional hub style ground blind with multiple hub assemblies is used, then structural stability is improved, but assembly time increases

Engineering Contradiction:

Improvestructural stabilityVSAvoidassembly time

Core Design Contradiction:

Stability of the object's compositionVSLoss of time

Solution Approach 1:

The patent combines multiple hub assemblies into a single integrated hub assembly that supports multiple walls. The single hub assembly includes a central hub with multiple rods extending to support the front wall, first side wall, and second side wall, eliminating the need for separate hub assemblies at each corner and reducing overall weight while maintaining structural stability.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The hub assembly is designed to be pre-assembled as a single unit with all rods and connections prepared in advance. This preliminary preparation allows the entire hub structure to be deployed quickly by simply extending the telescoping rods, rather than requiring multiple separate assemblies to be constructed and connected during field setup.

Inventive Principle:

Principle #10Preliminary action

3Adaptability or versatility

If apertures for gun rests and dog door features are added, then bird hunting effectiveness is improved, but device complexity increases

Engineering Contradiction:

Improvebird hunting effectivenessVSAvoidblind complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent incorporates apertures specifically in the front wall to provide gun rest functionality, and includes a dog door feature in an appropriate location for animal access. These specialized features are placed only where needed for bird hunting operations, rather than adding complexity throughout the entire blind structure. The local addition of these features maintains simplicity in other areas.

Inventive Principle:

Principle #3Local quality

AI summary

A foldable hunting blind uses a hub assembly to easily expand into its final configuration with side supports used to stabilize the blind. Further, the foldable hunting blind includes apertures in each wall configured to hold and direct firearm muzzles away from hunters within the blind and a door through the front wall allowing a dog to easily enter and exit the blind.
