Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual matching of vibration signal according to auditory signal is used, then vibration experience can be configured, but it is inefficient and subject to subjective factors with high requirements on individual configuration
Solution Approach 1:
The system automatically generates vibration signals by processing audio signals through feature extraction and parameter conversion, eliminating the need for manual configuration. The audio signal processing system autonomously transforms auditory features into corresponding vibration characteristics, making the process self-service and removing dependency on user expertise.
Solution Approach 2:
The patent replaces manual mechanical matching with automated signal processing. Instead of requiring users to manually adjust vibration parameters based on auditory perception, the system uses computational algorithms to automatically convert audio features into vibration signal parameters, substituting human operation with automated electronic processing.
2Ease of manufacture
If simple vibration melody is applied to notification and timer reminder, then implementation is simple, but user is prone to numbness after long time of use
Solution Approach 1:
The system dynamically generates vibration signals based on the characteristics of audio signals. Instead of using static simple vibration patterns, the vibration characteristics are continuously adapted to match the temporal and spectral features of the accompanying audio, creating dynamic and engaging vibration experiences that prevent user numbness.
Solution Approach 2:
The patent changes vibration parameters such as frequency, amplitude, and waveform characteristics based on extracted audio features. By modulating these parameters to correspond with audio signal characteristics, the system creates varied and engaging vibration patterns that maintain user attention while remaining simple to implement through automated parameter transformation.
3Adaptability or versatility
If manual matching of vibration signal is used, then configuration can be performed, but it has high requirements on individual person who configures vibration
Solution Approach 1:
The system provides universal vibration signal generation that works across different applications and scenarios. The same audio signal processing pipeline can generate appropriate vibration signals for notifications, timers, games, and movies, making the system universally applicable without requiring different configurations for each use case.
Solution Approach 2:
The automated system eliminates the need for user expertise in vibration configuration. The audio signal processing automatically adapts vibration parameters to match the audio characteristics, making the system accessible to all users regardless of their technical knowledge or preferences.
