Game Call Open Arch Frame Notch Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional diaphragm game calls suffer from variations in sound production due to differences in mouth shape, require high skill to seal properly, and can cause a gag reflex, with limited air circulation and difficulty in producing high-pitched sounds that require air passage over the diaphragm.
Innovation Solution
A game call with an open frame and notch above a diaphragm, featuring a U-shaped frame with a flexible diaphragm and an open arch frame that allows air passage above the diaphragm, enabling consistent high-pitched sounds by directing air flow through a central air passage notch.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a sealed resonance chamber is used to produce consistent sounds, then sound consistency is improved, but air circulation above the diaphragm is restricted and high-pitched sounds cannot be produced
Solution Approach 1:
The frame is divided into two distinct parts: a U-shaped frame that forms a sealed resonance chamber below the diaphragm, and an open arch frame that creates an unsealed chamber above the diaphragm. This segmentation allows the device to simultaneously achieve consistent sound production through the sealed lower chamber while enabling air circulation above the diaphragm through the open upper chamber, thereby producing both low and high-pitched sounds.
Solution Approach 2:
The invention adds a vertical dimension to the resonance chamber structure by stacking a sealed chamber below the diaphragm and an unsealed chamber above the diaphragm. This dimensional arrangement allows independent acoustic functions in different spatial zones, enabling the diaphragm to be excited from below while air flows over it from above, producing a broader range of pitches.
2Reliability
If the diaphragm is sealed to the roof of the mouth to produce desired sounds, then sound production is improved, but user skill requirement increases and gag reflex is triggered
Solution Approach 1:
The open arch frame acts as an intermediary structure that provides tactile feedback and spatial reference points for the user. The open arch frame's geometry guides proper placement of the device in the mouth without requiring the user to achieve a precise seal, as the open structure above the diaphragm allows air flow and sound production even with imperfect sealing.
3Speed
If a small portion of the diaphragm moves to produce high-pitched sounds, then pitch is improved, but placement consistency becomes difficult due to the small size relative to mouth variations
Solution Approach 1:
The invention creates different local acoustic environments above and below the diaphragm. The open arch frame establishes a localized unsealed chamber above the diaphragm that facilitates high-pitched sound production, while the U-shaped frame creates a sealed chamber below for low-pitched sounds. This local quality differentiation allows the same diaphragm to produce diverse pitches based on airflow direction rather than requiring precise placement for each pitch.
4Device complexity
If a single resonance chamber is used, then device simplicity is maintained, but tonal variety is limited
Solution Approach 1:
The acoustic chamber is segmented into two functional zones: a sealed lower chamber for low-pitched resonance and an unsealed upper chamber for high-pitched resonance. This segmentation of the single chamber into distinct acoustic zones allows the device to produce a wide tonal range while maintaining relative structural simplicity, as both chambers share the same basic frame and diaphragm components.
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 open frame and notch design facilitates easier placement and use, reduces the gag reflex, and allows for a wider range of sounds by ensuring consistent air flow and vibration of the diaphragm, making it easier for users to produce high-pitched calls with minimal practice.
Implementation Method 1
causing air to flow past the diaphragm, the air causing the Flexible Diaphragm to move against the Open Arch Frame and vibrate within the central Air Passage Notch section
Implementation Method 2
produce consistent high-pitched mammal or bird simulating sounds
Implementation Method 3
allows air passage above the diaphragm, enabling consistent high-pitched sounds by directing air flow through a central air passage notch
