Offset-Skirt Game Call for Airflow Turbulence Variation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing game calls with centered diaphragm designs limit sound variation and are not durable for repeated use, as they rely on tape or elastomeric holders that may not provide sufficient turbulence or durability.
Innovation Solution
A game call holder formed from elastomeric material with a one-piece design, featuring a skirt offset from the body's centerline, allowing for varied turbulence and improved durability by using materials safe for oral use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a centered diaphragm design is used, then the structure is simple and easy to manufacture, but sound variation is limited
Solution Approach 1:
The patent applies asymmetry by offsetting the diaphragm from the centerline of the holder body. The diaphragm is positioned such that its centerline is offset from the holder's centerline, creating an asymmetric configuration that generates varied turbulence patterns and sound variations while maintaining a relatively simple single-piece molded structure
2Reliability
If tape or traditional elastomeric holders are used, then the game call can be manufactured, but durability for repeated use is insufficient
Solution Approach 1:
The patent merges the holder body and skirt into a single integrated elastomeric component molded as one piece. This eliminates the need for separate tape layers or multiple assembled parts, improving durability through a unified structure that can withstand repeated use while maintaining ease of manufacture through single-step molding processes
Solution Approach 2:
The patent uses elastomeric material that combines the properties of flexibility and durability. The elastomeric holder provides both the structural integrity needed for repeated use and the flexibility required for oral use safety, creating a composite solution that satisfies both durability and manufacturability requirements
3Adaptability or versatility
If a centered skirt design is used, then the structure is symmetric and simple, but turbulence and sound variation are insufficient
Solution Approach 1:
The patent applies asymmetry by positioning the skirt such that its centerline is offset from the holder body's centerline. This asymmetric skirt configuration creates varied turbulence patterns as air flows through the game call, generating different sound variations while maintaining a relatively simple geometric design that is easy to manufacture
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
The offset design enhances sound variation and durability, enabling repeated use without damage, while ensuring safety and comfort in the user's mouth.
Implementation Method 1
The holder can be formed from materials that are safe for inclusion in a user's mouth, and which are sufficiently durable so that the game call can be used repeatedly without the holder being damaged
Implementation Method 2
by including an offset of skirt relative to centerline of the body portion between the top and bottom surfaces of the body portion, different amounts of turbulence can be created as compared to a centered design

AI summary
A game call includes a holder molded from an elastomeric material that is configured to retain to a resting shape. A body portion of the holder includes a slot formed in an inward-facing surface of the body that extends around a cutout positioned at a front side of the body. The slot formed in the body portion is designed to receive and retain a reed insert that includes a diaphragm configured to extend across the cutout when the reed insert is received in the holder. The holder is designed such that a centerline of an outer skirt is located below a centerline of the body portion such that more than 50% of the thickness of the body portion is above the centerline of the skirt. The offset of the skirt modifies the airflow over the diaphragm.
