Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If rotary vibrators are used to generate vibrations, then the device structure is simple, but the ability to produce complex waveforms and vary vibration intensity independently is limited
Solution Approach 1:
The patent replaces the rotary mechanical vibrator system with an electromagnetic system consisting of a coil and permanent magnet. This substitution enables the generation of complex vibration waveforms through electrical signal control while maintaining mechanical simplicity in the actuator design. The electromagnetic system allows independent adjustment of vibration intensity and frequency patterns that cannot be achieved with rotary vibrators.
2Speed
If rotary vibrators are used, then the device is mechanically simple, but the response time to control signals is slow
Solution Approach 1:
The electromagnetic actuator system responds instantaneously to electrical control signals, providing rapid reaction time compared to mechanical rotary vibrators. The coil and magnet system can start, stop, and change vibration patterns immediately when electrical signals are applied, enabling precise control for therapeutic applications.
3Adaptability or versatility
If rotary vibrators are used, then the device is simple, but the ability to vary vibration strength without changing frequency is limited
Solution Approach 1:
The electromagnetic system allows independent control of vibration parameters by changing electrical signal characteristics. The vibration strength can be varied by adjusting the amplitude of the electrical signal applied to the coil, while the frequency pattern remains determined by the mechanical system's natural frequency. This enables independent adjustment of vibration intensity without altering frequency patterns.

AI summary
A vibrator apparatus includes a moving coil, which is rigidly attached to a member, e.g. a frame or beam, of a vibration device. The moving coil is for an elected vibration mode of the apparatus configured to receiving electric signals, e.g. pulsating and/or sinusoidal electric signals, from a signal unit. The moving coil co-operates with a permanent magnet, which is suspended by springs attached to the member, and the coil and the magnet are mutually linearly and coaxially movable upon application of electric signals to the moving coil. An actual distance of movement being part of a distance between extreme positions and being less than the axial length of the moving coil. The springs are located at a distance from a respective axial end portion of the permanent magnet.
