Game Bag Handling Structure for Heavy Carcass Transport
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing game bags are difficult to lift, carry, and maneuver due to their weight and bulk, especially when loaded with heavy carcass portions, and they often leak bloody liquid, with limited options for hanging and carrying by multiple people.
Innovation Solution
The design includes a handling structure with a single or dual handle system adjacent the closed end, reinforced with stitching and suitable materials, and a two-drawstring closure mechanism for improved grip and maneuverability, allowing for easier lifting and carrying by one or two people, while maintaining separation from the liquid.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the bag is made larger to accommodate heavy carcass portions, then the carrying capacity is improved, but the difficulty of lifting and maneuvering increases
Solution Approach 1:
The handling structure is segmented into multiple components: a first handle for one person and a second handle for another person. This segmentation allows the heavy bag to be distributed and managed by multiple individuals, resolving the contradiction between large carrying capacity and ease of maneuvering.
Solution Approach 2:
The handles act as intermediary structures between the heavy bag and the carriers. By providing dedicated gripping points (handles) rather than requiring direct contact with the bag body, the intermediary handles make it easier to lift and control the heavy load.
2Strength
If the closed end of the bag is made heavier to support the carcass portion, then the structural strength is improved, but the difficulty of lifting increases
Solution Approach 1:
The first handle serves as an intermediary that provides a dedicated lifting point at the heavy closed end. This allows carriers to grip and lift the heavy end without direct contact with the carcass, maintaining structural strength while improving ease of lifting through proper force application points.
Solution Approach 2:
The handling structure with multiple handles is pre-configured on the bag before use. This preliminary arrangement of handles ensures that lifting points are already positioned optimally, allowing users to immediately grasp and lift the heavy bag without needing to create or locate gripping points during the loading process.
3Quantity of substance
If the bag is made bulkier to accommodate large carcass portions, then the carrying capacity is improved, but the difficulty of gripping the fabric increases
Solution Approach 1:
The handles serve as intermediary gripping structures that replace direct contact with the bag fabric. By providing dedicated handles with appropriate size and shape, carriers can grip these intermediaries rather than struggling to grasp the bulky bag fabric directly, thereby improving ease of gripping while maintaining large carrying capacity.
4Device complexity
If the bag uses a single drawstring closure, then the device complexity is reduced, but the versatility of hanging options is limited
Solution Approach 1:
The closure system is segmented into multiple drawstrings (first drawstring and second drawstring) rather than using a single drawstring. This segmentation provides multiple independent closing and hanging points, increasing versatility for different hanging scenarios while keeping each individual drawstring mechanism simple and familiar.
Solution Approach 2:
The multiple drawstrings provide multi-functionality: they can be used independently or together for closing the bag, and they provide multiple attachment points for hanging the bag in various orientations. This universal design allows the same simple drawstring mechanism to serve multiple purposes and adapt to different hanging scenarios.

AI summary
A bag is provide for receiving and holding contents at least as heavy and bulky as a portion of a large animal carcass. The bag may configured to be carried by a person and may including a containing portion defining a closed end, an open end opposite the closed end, and a side portion interconnecting the closed end and the open end. The open end may be configured for operation between a holding configuration for holding the carcass portion in the bag and a passing configuration for passing the carcass portion through the open end. The bag may further include a closure mechanism adjacent the open end for selectively closing the open end to provide the holding configuration and opening the open end to provide the passing configuration. The bag may also define a midline between the open end and closed end and further include a handling structure positioned on the closed end side of the midline.
