Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If many vibration patterns are stored to provide diverse vibration control, then the variety of vibration patterns is improved, but the amount of data used for controlling the vibrator increases
Solution Approach 1:
The patent uses model functions (frequency model function and amplitude model function) as templates to generate vibration patterns. Instead of storing complete vibration pattern data, the system stores compact model functions that can be evaluated to produce vibration information. This copying approach allows diverse vibration patterns to be generated from a small number of parameter sets, dramatically reducing the data amount while maintaining pattern variety.
Solution Approach 2:
The patent employs model functions with adjustable parameters (frequency variable, period variable, amplitude variable) to generate different vibration patterns. By changing the parameter values while keeping the same model function structure, the system can produce a wide variety of vibration patterns without storing multiple complete pattern datasets. This parameter-based generation resolves the contradiction between pattern diversity and data size.
2Duration of action of moving object
If vibration patterns are combined to extend duration, then the duration of vibration is improved, but the complexity of managing vibration patterns increases
Solution Approach 1:
The patent divides long-duration vibration patterns into multiple segments, where each segment is generated by evaluating the model function for a specific time period. The vibration information is generated by combining multiple evaluation results across different time segments. This segmentation approach allows long vibration patterns to be constructed systematically from the same model function, reducing management complexity compared to storing and coordinating multiple complete pattern files.
