Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed-frequency vibration system is used in the roller, then the structure is simple, but the adaptability to different tissue areas and therapeutic needs is limited
Solution Approach 1:
The patent implements a dynamic vibration system where the vibration frequency can be adjusted during operation. The motor speed controller enables continuous variation of rotational speed, which directly controls the vibration frequency generated by the eccentric mass. This dynamic adjustment capability allows the device to adapt to different therapeutic requirements and tissue areas without requiring multiple fixed-frequency devices.
2Reliability
If multiple vibration frequencies are provided, then the therapeutic effectiveness is improved, but the control system complexity increases
Solution Approach 1:
The patent changes the operational parameters of the vibration system by allowing continuous adjustment of the motor's rotational speed. The motor speed controller modifies electrical parameters (voltage/frequency) to the motor, which in turn changes the mechanical parameter of rotational speed. This single-parameter control approach achieves multiple vibration frequencies without requiring complex multi-mode control systems, maintaining simplicity while improving therapeutic effectiveness.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The roller provides targeted and customizable vibrations, enhancing muscle flexibility, reducing muscle fibrosis, and improving tissue regeneration by varying the frequency and amplitude of vibrations, thereby improving the overall therapeutic experience.
Implementation Method 1
A motor positioned within the shell near the other end cap provides electrical power to cause the motor to rotate an output shaft at a plurality of angular velocities to rotate an eccentric mass located approximately midway between the two end caps. The rotating eccentric mass causes vibration.
Data Source
AI summary
A portable vibrating roller includes an outer roller structure having a plurality of grooves and ribs. A hollow cylindrical bore extends longitudinally through the shell. A vibration system having a first end cap and a second end cap fits within the bore. A battery positioned within the shell near one end cap provides electrical power to a motor positioned within the shell near the other end cap to cause the motor to rotate an output shaft at a plurality of angular velocities to rotate an eccentric mass located approximately midway between the two end caps. The rotating eccentric mass causes vibration. A motor control circuit receives input power from a battery and selectively provides output power to the motor in response to the operation of a switch on the first end cap. The output power is varied to control the angular velocity of the output shaft of the motor and to thereby control a frequency of vibration caused by the eccentric mass.
