Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If standard vibration parameters are applied to all participants, then device simplicity is maintained, but proprioceptive illusion effectiveness deteriorates
Solution Approach 1:
The vibration system transitions from static fixed parameters to dynamic adjustable parameters, allowing frequency and amplitude to be modified in real-time based on individual participant requirements and muscle group characteristics, thereby resolving the contradiction between device simplicity and effectiveness
Solution Approach 2:
The system enables continuous adjustment of vibration frequency and amplitude parameters to match the specific needs of different participants and muscle groups, transforming the fixed-parameter limitation into a flexible parameter-controlled solution that maintains both simplicity and reliability
2Ease of manufacture
If commercial vibrators with fixed frequency settings are used, then manufacturing simplicity is maintained, but adaptability to different individuals and muscle groups deteriorates
Solution Approach 1:
The vibration generator is designed with dynamic control capabilities that allow frequency and amplitude adjustment, maintaining manufacturing simplicity while enabling adaptability to different participants and muscle groups through software-controlled parameter modification
Solution Approach 2:
The vibration system is designed as a universal device that can be applied to various muscle groups and participants by adjusting parameters rather than requiring multiple specialized devices, achieving both manufacturing efficiency and broad adaptability
3Device complexity
If uniform amplitude vibration is applied, then device simplicity is maintained, but measurement precision of proprioceptive response deteriorates
Solution Approach 1:
The system enables precise control and adjustment of vibration amplitude parameters to optimize proprioceptive illusion induction for different participants and experimental conditions, transforming the uniform amplitude limitation into a precision-controlled parameter that enhances measurement accuracy

AI summary
Conventional proprioceptive studies use commercial vibrators. Such vibrators have major drawbacks as their amplitude and frequency adjustments are limited or outside the range of frequency that stimulates the specific human biological sensors making them non-specific to each individual or muscle. At times, they are also expensive and not wearable. The presently disclosed subject matter relates to system and method for custom-developed vibrational systems having various adjustable and flexible parameters such as amplitude, frequency, delay time, and other user requirement functions that can work simultaneously and can be applied to different individuals and to different muscle spots. The presently disclosed system and method are robust, compact, wearable, economical, and easy to operate.
