Engineering Contradiction Analysis
1Productivity
If manual adjustments based on patient weight are used, then the system structure is simple, but the treatment efficiency and transmissibility optimization are insufficient
Solution Approach 1:
The system automatically measures patient weight using integrated circuitry and accelerometers, and self-adjusts oscillation frequency and amplitude without manual intervention. This enables the system to optimize transmissibility of mechanical vibration energy automatically, improving treatment efficiency while maintaining reasonable system complexity through automated self-service functionality.
Solution Approach 2:
The patent replaces manual mechanical adjustment with electronic sensing and control systems. Accelerometers and integrated circuitry detect patient weight and automatically control oscillation parameters, substituting manual mechanical operations with electronic systems to improve efficiency and precision.
2Reliability
If fixed oscillation parameters are used, then the device operation is simple, but the transmissibility of mechanical vibration energy is insufficient
Solution Approach 1:
The system dynamically adjusts oscillation frequency and amplitude based on real-time patient weight measurement. Instead of fixed parameters, the oscillation characteristics change adaptively to maximize transmissibility of mechanical vibration energy through the patient's body, ensuring optimal treatment efficacy while the automated control maintains operational simplicity.
Solution Approach 2:
The system uses accelerometers to measure patient response and feeds this information back to the control circuitry, which automatically adjusts oscillation parameters. This closed-loop feedback mechanism ensures optimal transmissibility and treatment efficacy while maintaining ease of operation through automated adjustment.
3Strength
If high frequency oscillation is applied, then bone growth promotion is enhanced, but patient discomfort may increase due to inadequate transmissibility control
Solution Approach 1:
The system changes oscillation parameters (frequency and amplitude) based on patient weight and response to maximize transmissibility. By dynamically adjusting these parameters, the system delivers effective high-frequency vibration for bone healing while controlling amplitude and duration to minimize patient discomfort, achieving optimal therapeutic effect with reduced adverse effects.

The system provides personalized and efficient dynamic motion therapy by automatically adjusting treatment parameters, enhancing bone healing and reducing discomfort by maximizing the transmissibility of mechanical vibration energy through the patient's body.
Implementation Method 1
an oscillating platform apparatus that can be actuated to oscillate vertically, so that resonant vibrations caused by the oscillation of the platform, together with acceleration brought about by the body weight of the patient, provides stress levels
Implementation Method 2
The accelerometer transmits a first angular measurement to the digital signal processor after power-on and before the patient stands on the upper plate... Another angular measurement is received by the digital signal processor from this accelerometer after the patient stands on the upper plate

AI summary
Apparatus and methods for therapeutically treating bone fractures, osteopenia, osteoporosis, or other tissue conditions, postural instability, or other conditions, such as cystic fibrosis, Crohn's disease and kidney and gall bladder stones. An oscillating platform apparatus supports a body to be treated. An oscillator is positioned within the platform apparatus and is configured to impart an oscillating force on the body. Two accelerometers are mounted to the platform apparatus for determining the acceleration and weight of the body. Once the weight of the body is determined, the amplitude of the frequency of the oscillating force and/or frequency of the oscillating force is adjusted to provide a desired therapeutic treatment to the patient. Information received from the two accelerometers is also used to determine the posture of the patient and the transmissibility of the mechanical vibration energy generated by the oscillating force through the body.
