Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional personal vibrating devices lack the capability to provide immersive multi-sensory experiences by synchronizing vibrations with audio, resulting in a simplistic and less engaging user experience.
Innovation Solution
A vibrating stimulation system that synchronizes vibrations with audio signals in terms of frequency and amplitude, using control devices with internal electronics to generate synchronized vibration signals, which are transmitted to stimulation devices, creating an immersive experience through advanced signal processing techniques such as filtering and gain control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional vibrating devices are used, then the device structure remains simple, but the user experience lacks immersion and multi-sensory engagement
Solution Approach 1:
The patent combines audio output and vibration output into a single integrated device, merging previously separate functions (speakers and vibrators) into one unified system. This allows synchronized audio-vibration experiences while maintaining a compact form factor, directly addressing the contradiction between enhanced adaptability and device complexity
Solution Approach 2:
The device performs multiple functions simultaneously - it acts as both an audio playback device and a vibration stimulation device. The single device can deliver auditory stimuli and tactile vibrations, creating multi-sensory experiences without requiring multiple separate devices, thus improving versatility while managing complexity
2Adaptability or versatility
If vibration intensity is increased to enhance stimulation, then user engagement improves, but synchronization with audio becomes more difficult to maintain
Solution Approach 1:
The system uses feedback mechanisms to continuously monitor and adjust vibration output based on audio input characteristics. The controller receives audio signals, analyzes their properties (frequency, amplitude, rhythm), and dynamically adjusts vibration parameters in real-time to maintain precise synchronization, even when intensity varies
Solution Approach 2:
The vibration characteristics are made dynamic rather than static - the system continuously adapts vibration frequency and intensity based on the changing audio signal. This dynamic adjustment allows the device to respond to musical beats, rhythms, and intensity changes, maintaining synchronization across varying conditions

AI summary
An immersive stimulation system generates audio (such as music) and a vibration signal that causes a stimulation device to vibrate synchronously with the audio. The vibrations may be synchronized with respect to amplitude and frequency such that frequency components of the vibrations adapt in coordination with time-dependent frequency distributions of the audio. The immersive stimulation system may include a control device for generating the audio and vibration signals and a stimulation device that produces the vibrations based on the vibration signal. The stimulation device may include one or more voice coil transducers to produce the vibrations and a detachable vibratory unit that may have different form factors depending on the desired usage of the stimulation system.
