Portable Animal Call Device Simplified Control Interface
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional animal call devices are often complex and require significant user input, diverting attention and increasing the risk of startling animals, as they need to navigate menus, interpret symbols, or handle small controls to change between sound recordings.
Innovation Solution
A portable electronic animal call device with a simple button-based interface that allows users to easily select and control animal sound recordings, featuring a housing with ridges and recesses for grip, a memory for storing multiple sound files, a speaker, amplifier, and a controller that initiates sounds based on user input, minimizing the need for complex navigation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional animal call devices use electronic playback with multiple controls and menu navigation, then the ability to reproduce animal sounds is improved, but the device complexity and user input requirements increase
Solution Approach 1:
The patent extracts only the essential control functions needed for animal calling, removing unnecessary menu navigation and complex settings. The device provides core sound playback functionality with minimal controls (power button, volume up/down, and a single select button), eliminating the complexity of conventional electronic devices while maintaining reliable animal sound reproduction.
Solution Approach 2:
Instead of requiring users to navigate complex menus to access basic functions, the patent inverts the control logic: the single select button cycles through sound options automatically, and pressing it again confirms selection and plays the sound. This reverses the conventional approach where users must dig through multiple menu levels to reach simple playback functions.
2Measurement precision
If conventional animal call devices require significant user input and menu navigation, then control precision is improved, but the user's attention is diverted from hunting or photography activities
Solution Approach 1:
The device performs self-service by automatically cycling through sound options when the select button is pressed, eliminating the need for users to navigate menus or make precise sequential inputs. The system handles the complexity of sound selection internally, requiring only simple button presses from the user, thus maintaining control precision while minimizing attention diversion from hunting or photography activities.
3Reliability
If conventional animal call devices have complex input schemes, then the ability to control sound playback is improved, but the risk of making unwanted sounds and movement that could startle animals increases
Solution Approach 1:
The patent removes unnecessary control steps and menu navigation that increase the risk of accidental sounds and movements. By providing direct access to sound playback through minimal buttons, the device eliminates the intermediate steps where users might inadvertently make noise or movement that could startle animals, while maintaining reliable sound playback control.
4Adaptability or versatility
If conventional animal call devices require multiple buttons and menu navigation, then functionality is improved, but the ease of use during hunting or photography is worsened
Solution Approach 1:
The patent makes the single select button perform multiple functions: cycling through sound options, confirming selection, and initiating playback. This multi-functional design provides versatile sound selection capability while maintaining simplicity, allowing users to operate the device easily during hunting or photography activities without needing multiple dedicated buttons or complex menu navigation.
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
Enables users to activate and switch between animal sound recordings with minimal input, reducing the risk of startling animals and improving usability, allowing for effective sound control without distracting from other activities like hunting or photography.
Implementation Method 1
The speaker broadcasts the animal sounds
Implementation Method 2
The amplifier increases and decreases the amplitude of the sound signal between the controller and the speaker for increasing and decreasing the volume of the animal sounds
Data Source
AI summary
A portable electronic animal call device comprising a housing, a memory, a plurality of user inputs, a speaker, an amplifier, a power source, a status indicator, and a controller for controlling the electronic components. The housing encloses the electronic components and includes a plurality of sound openings near the speaker. The housing also includes a plurality of ridges and recesses for gripping the device. The memory stores animal sound files therein. The inputs include a power button, a plurality of animal sound selection buttons, and one or more volume inputs. The user holds or presses the power button to turn on and off the device and to resume and pause an animal sound. The user presses one of the animal sound selection buttons to select and play a desired animal sound. The status indicator communicates a power or animal sound status via LED light or similar alert.
