Variable Sound Generator for Pet Toys
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pet toys with sound generating capabilities are limited to producing only a single sound, failing to provide varied auditory experiences based on movement direction and magnitude, which restricts their interactive appeal.
Innovation Solution
A device incorporating an accelerometer connected to a control circuit that regulates a sound chip to emit sounds with varying characteristics depending on the direction and magnitude of movement, allowing for multiple sound levels and speeds based on detected motion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single sound generating device (reed or whistle) is used in the toy, then the device structure remains simple, but the toy can produce only a single sound, limiting its appeal to pets
Solution Approach 1:
The patent applies dynamics by making the sound generation characteristics variable rather than fixed. The control circuit dynamically selects different sound characteristics (pitch, volume, type) based on real-time acceleration data from the accelerometer, allowing a single physical device to produce multiple sound variations in response to different movement conditions.
Solution Approach 2:
The patent changes physical parameters of sound generation by using an accelerometer to detect movement characteristics and a control circuit to adjust sound parameters (pitch, volume, type) accordingly. This transforms a static sound generator into a dynamic one that adapts its output based on measured physical quantities.
2Adaptability or versatility
If a prerecorded sound chip is used to enable multiple sounds, then the toy can produce varied sounds, but the device complexity increases due to additional components (battery, sound chip assembly)
Solution Approach 1:
The patent makes the accelerometer serve multiple functions: it not only detects movement for sound activation but also characterizes the movement (direction, magnitude, type) to determine which sound characteristics to generate. This multi-functionality reduces the need for separate sensors and control logic for each sound mode.
Solution Approach 2:
The system uses the movement data detected by the accelerometer to automatically control the sound generation characteristics without requiring external input or complex programming. The movement characteristics directly determine the sound output, creating a self-regulating system where the toy's physical interaction with the pet controls its auditory response.
3Ease of operation
If movement-activated sound generation is implemented, then the toy becomes more interactive, but the device requires additional sensing components and control circuits
Solution Approach 1:
The patent implements feedback by using the accelerometer to continuously monitor movement and the control circuit to adjust sound characteristics in real-time based on this feedback. The sound output is directly coupled to the detected movement parameters, creating a closed-loop interactive system that responds dynamically to the pet's actions.
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 device enhances the interactive value of pet toys by generating sounds with distinct characteristics in response to movement, providing a more engaging experience for pets by adapting sound output to the direction and intensity of motion.
Implementation Method 1
an accelerometer, connected to a control circuit that controls the speed at which a pre-recorded sound is generated by a sound chip in response to movement of the device in which the accelerometer is housed
Data Source
AI summary
The device includes an accelerometer for sensing a parameter of movement, such as direction and/or magnitude. A pre-recorded sound is played in response to the sensed movement. The speed and/or pitch at which the pre-recorded sound is played is a function of the sensed movement parameter. There may be one or more pre-recorded sounds from which playback is chosen. In one embodiment, hardwired circuits set the characteristics of the generated sound in accordance with the accelerometer output. In a second embodiment, the software selects which pre-recorded sound to play and sets the characteristics of the sound based upon parameters sensed by the accelerometer.
