Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional vibration devices transmit low-frequency vibrations for bodily sensation, then vibration transmission function is achieved, but therapeutic applications for bone fracture treatment are insufficient and may cause discomfort or irritation
Solution Approach 1:
The patent combines multiple vibration sources (speaker, piezoelectric element) and signal types (aperiodic continuous signals, electromagnetic waves) into a single vibration device. This merging enables diverse therapeutic applications including bone fracture treatment while the coordinated control of multiple components prevents discomfort and irritation by distributing the therapeutic effect across different mechanisms.
Solution Approach 2:
The patent employs aperiodic continuous signals with varying frequency and amplitude parameters, unlike conventional periodic signals. This parameter variation allows the device to adapt to different therapeutic needs (such as bone fracture treatment) while avoiding the monotonic stimulation that causes discomfort, thereby expanding adaptability without increasing harmful effects.
2Adaptability or versatility
If vibration devices use simple periodic signals, then device complexity is low, but therapeutic effectiveness for bone fracture treatment is insufficient
Solution Approach 1:
The patent replaces complex mechanical signal generation systems with an electromagnetic approach using a speaker and piezoelectric element controlled by aperiodic continuous signals. This substitution achieves diverse therapeutic stimulation (improving adaptability) while reducing mechanical complexity, as electromagnetic signal generation is inherently more flexible and easier to control than mechanical vibration mechanisms.
3Adaptability or versatility
If vibration devices transmit only mechanical vibration, then structure is simple, but inability to provide combined electromagnetic wave therapy reduces therapeutic benefit
Solution Approach 1:
The patent designs the vibration device with multi-functionality by integrating both mechanical vibration transmission (via speaker and case) and electromagnetic wave generation (via piezoelectric element). This universal design enables the single device to provide combined therapy types (mechanical vibration plus electromagnetic stimulation) for enhanced therapeutic benefit, particularly for bone fracture treatment, without requiring multiple separate devices.

AI summary
A vibration device that vibrates in accordance with a reproduction signal. The vibration device includes: a vibration generation section including a speaker that is configured to generate a sound wave in accordance with the reproduction signal, to thereby generate vibration; a power generation section including a piezoelectric element that generates a current corresponding to the reproduction signal by the vibration of the vibration generation section; an electromagnetic wave generation section including a coil substrate, into which the current generated by the power generation section flows to thereby generate an electromagnetic wave that is spatially radiated; and a body section including a cylindrical case that accommodates the vibration generation section, the power generation section, and the electromagnetic wave generation section. The vibration generated by the vibration generation section is transmitted to a user via the case.
