Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing hunting blinds with hand-activated hatch covers delay hunters in taking shots, pose safety risks due to accidental firearm discharge, spook game with loud and visible opening mechanisms, are unreliable in wet conditions, and are cumbersome to transport and adjust for varying terrain and camouflage needs.

Innovation Solution

A hands-free hunting blind system using a frame with flexible sheets of fabric coupled via magnetic or hook-and-loop couplers, allowing hunters to rise and take aim without opening the blind, maintaining concealment and reducing noise and obstruction, while being adjustable and reliable in various weather conditions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If hand-activated hatch covers are used in hunting blinds, then the blind can be opened to allow hunters to exit and take shots, but this delays hunters in taking shots and creates safety risks due to accidental firearm discharge

Engineering Contradiction:

Improveease of blind openingVSAvoidtime delay in taking shots

Core Design Contradiction:

Ease of operationVSLoss of time

Solution Approach 1:

The patent replaces the traditional hand-activated mechanical hatch cover system with a spring-loaded automatic opening mechanism. The spring system automatically propels the hatch cover open when the hunter exits the blind, eliminating the need for manual operation and reducing the time delay between exiting and taking a shot.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The spring-loaded mechanism enables the blind opening system to be self-activating. Once the hunter triggers the release mechanism (either manually or automatically via exit sensor), the spring automatically opens the hatch cover without requiring the hunter to manually handle the opening operation, thereby reducing time loss and improving safety.

Inventive Principle:

Principle #25Self-service

2Ease of operation

If hand-activated hatch covers are used, then hunters can access the blind interior, but this poses safety risks due to accidental firearm discharge and spooks game with loud and visible opening mechanisms

Engineering Contradiction:

Improveease of blind accessVSAvoidnoise and visibility disturbance to game

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The patent replaces the manual hand-activation mechanism with an automatic spring-loaded system that opens the hatch cover silently and quickly. This substitution eliminates the loud manual manipulation noise and reduces the visual disturbance to game, as the automatic mechanism operates faster and more quietly than manual operation.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The spring-loaded mechanism is pre-charged and ready to open the hatch cover immediately when triggered. This preliminary preparation allows the blind opening to occur rapidly and quietly upon trigger activation, minimizing the time and noise exposure to game before the hunter is in position to take a shot.

Inventive Principle:

Principle #10Preliminary action

3Ease of operation

If traditional blind opening mechanisms are used, then hunters can exit the blind, but these mechanisms are unreliable in wet conditions and cumbersome to transport and adjust

Engineering Contradiction:

Improveease of blind openingVSAvoidreliability in wet conditions

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The patent replaces traditional mechanical latch and handle systems with a spring-loaded automatic opening mechanism that is less susceptible to wet condition failures. The spring mechanism and associated triggers are designed to maintain reliability in adverse weather, while the modular design facilitates easier transport and adjustment compared to traditional integrated blind structures.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)
