Electric Bed Sound Synchronization Using Ambient Audio Matching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electric beds or chairs cannot move synchronously with ambient sounds, such as those from movies or music, due to technical difficulties in real-time synchronization.
Innovation Solution
An electric bed or chair equipped with a frame structure, actuators, vibrators, a control unit, a receiving unit, a database, a sound sensor, and a comparative unit, which senses ambient sounds and matches them with pre-stored audio files to control the bed's movements and vibrations in sync with the audio signals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If real-time sound sensing and synchronization control are implemented, then the bed can move synchronously with ambient sounds, but the device complexity increases
Solution Approach 1:
The system is divided into distinct functional modules: sound sensor for detecting ambient sounds, comparative unit for matching sounds with database entries, database for storing audio files, control unit for processing synchronization signals, and actuator for executing movements. This segmentation allows each component to perform its specific function independently, managing overall system complexity while achieving real-time synchronization capability.
Solution Approach 2:
The comparative unit acts as an intermediary between the sound sensor and the control unit. It receives sound signals, matches them with pre-stored audio files in the database, and translates ambient sounds into controllable commands for the actuator. This intermediary layer simplifies the control logic by using pre-matched audio patterns rather than requiring complex real-time sound analysis.
2Adaptability or versatility
If multiple components (sound sensor, comparative unit, database, control unit, actuator) are added to achieve sound synchronization, then the bed can move with ambient sounds, but the manufacturing complexity increases
Solution Approach 1:
The control unit serves multiple functions: it receives commands from the comparative unit, processes synchronization signals, controls the actuator movements, and coordinates with the database. This multi-functionality reduces the total number of separate components needed, simplifying manufacturing and assembly while maintaining full sound synchronization capability.
Solution Approach 2:
Audio files are pre-stored in the database with their corresponding sound patterns matched beforehand. This preliminary preparation allows the comparative unit to simply match incoming sounds with pre-processed patterns rather than analyzing sounds in real-time, significantly reducing computational complexity and simplifying the manufacturing of the control system.

AI summary
An electric bed (1, 1') or chair includes an actuator (20) connected with a base (12) and a movable frame (14), a vibrator (24) disposed on the movable frame (14), a control unit (30) controlling motions of the actuator (20) and the vibrator (24), a receiving unit (34) receiving audio files each having a specific time sequence, a database (38) storing the audio files, a sound sensor (40) sensing ambient sounds to transmit corresponding signals, and a comparative unit (44) comparing the signals transmitted by the sound sensor (40) with the audio files stored in the database (38) to locate a match audio file from the audio files, which is matched with the ambient sounds, and then transmit control signals to the control unit (30) for enabling the control unit (30) to control the actuator (20) or the vibrator (24) to move in accordance with the match audio file. As a result, the electric bed (1, 1') or chair moves along with the ambient sounds synchronously.
