Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single frequency sound source (tuning fork) is used, then the device structure is simple, but the frequency range and therapeutic applicability are limited
Solution Approach 1:
The patent uses a movable support member that can be adjusted to different positions, making the device dynamic rather than fixed. This allows the same device structure to produce multiple frequencies by changing the distance between the sound source and reflecting surface, resolving the contradiction between frequency range and structural complexity
Solution Approach 2:
The patent changes the physical parameter of distance between the sound source and reflecting surface to alter the resonant frequency. By adjusting this parameter, the device can generate different base frequencies and harmonics without changing the fundamental device structure, enabling frequency tuning while maintaining structural simplicity
2Adaptability or versatility
If the speaker is fixed at a single position, then the device structure is simple, but the frequency tuning capability is lost
Solution Approach 1:
The support member is designed to be movable along the central axis, transforming a static speaker position into a dynamic one. This mobility enables frequency tuning by adjusting the distance to the reflecting surface, while the guided movement path keeps the adjustment mechanism relatively simple
Solution Approach 2:
The patent introduces spatial dimensionality by allowing movement along the central axis perpendicular to the reflecting surface. This dimensional adjustment provides frequency control without requiring complex frequency-selective components, solving the tuning capability need while maintaining structural simplicity
3Productivity
If manual adjustment of speaker position is used, then the device structure is simple, but the tuning speed is slow
Solution Approach 1:
The patent incorporates a feedback control loop with a sensor that detects the actual distance between the speaker and reflecting surface, compares it to the desired distance, and automatically adjusts the position accordingly. This closed-loop feedback system enables rapid and accurate frequency tuning without manual intervention, resolving the contradiction between tuning speed and control complexity
Solution Approach 2:
The patent replaces manual mechanical adjustment with an automated control system that uses sensors and actuators. This substitution of manual operation with an automated control mechanism dramatically increases tuning speed while the modular nature of the control system keeps the added complexity manageable

Function Achieved in This Case
Enables generation of resonant sound at a range of frequencies, allowing for therapeutic applications tailored to specific conditions, with rapid frequency tuning capabilities.
Implementation Method 1
a sound reflecting body and a speaker fixed on a support member that is disposed through the sound reflecting body. The speaker generates sound in a first direction away from the sound reflecting body and in a second opposite direction toward the sound reflecting body.
Implementation Method 2
two streams of sound are constructively additive for a predetermined base frequency and harmonics thereof
Implementation Method 3
The support member is configured to move relative to the sound reflecting body to adjust a distance between the speaker and the sound reflecting body.
