Ventilated Game Bag With Mesh Airflow and Pest Blocking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing game bags interfere with airflow, leading to heat buildup and spoilage of harvested game meat, and lack mechanisms for controlled airflow and pest prevention.
Innovation Solution
A game bag design with mesh-covered openings, flaps for airflow control, and a bracket for mounting a circulating fan, along with multi-layer construction and pest-resistant features, to enhance airflow and prevent contamination.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If the game bag is made of solid material (cheesecloth or canvas) to protect the carcass from contamination and pests, then protection is improved, but airflow is blocked causing heat buildup and spoilage
Solution Approach 1:
The game bag incorporates mesh panels with controlled opening sizes that allow airflow while maintaining protection. The mesh structure provides porosity that enables air circulation to prevent heat buildup while still blocking pests and contamination, resolving the contradiction between protection and ventilation.
Solution Approach 2:
The game bag uses a composite construction combining solid fabric sections (for protection and water resistance) with mesh panel sections (for airflow). This composite approach allows different parts of the bag to serve different functions - solid areas provide contamination and pest protection while mesh areas enable cooling airflow.
2Temperature
If mesh openings are added to allow airflow, then cooling is improved, but pest protection is reduced
Solution Approach 1:
The mesh panels are designed with specific opening sizes and patterns that permit air circulation for cooling while maintaining aperture dimensions small enough to block insects and pests. The porous structure provides selective permeability - allowing air molecules to pass while blocking larger pest organisms.
3Adaptability or versatility
If flaps and sealing mechanisms are added to control airflow, then airflow control is improved, but device complexity increases
Solution Approach 1:
The game bag incorporates movable flaps at the mesh panel openings that can be adjusted to different positions. These dynamic elements allow the user to control airflow rates by opening or closing flaps, providing adaptability to different environmental conditions without requiring complex automated systems.
Solution Approach 2:
The airflow control system is divided into multiple independent flap sections, each controlling a specific mesh opening. This segmentation allows granular control of airflow through different parts of the bag, enabling localized adjustment based on carcass position and environmental conditions.
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
Facilitates controlled airflow and pest prevention, preventing spoilage and ensuring proper drying and cooling of game meat.
Implementation Method 1
when the fan is operating the fan causes air to flow along the first flow path, the second flow path, and within the chamber
Implementation Method 2
At least one upper mesh covered opening extends through the rear wall and provides a first airflow path through the rear wall

AI summary
Light-weight, collapsible and well-ventilated game bags having a circulating fan adapted to promote air circulated into, out of and throughout the game bags may be used by hunters to store and transport game that has been field dressed in a way that prevents contamination, spoilation and rotting of meat.
