Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a static description file is used to control the linear motor vibration, then the implementation is simple, but the vibration effect cannot be adapted to different interruption events
Solution Approach 1:
The patent implements dynamic adjustment of the driving waveform by comparing static and dynamic description files. When an interruption event occurs, the system dynamically modifies the driving waveform parameters based on the difference between the static description file (normal operation) and dynamic description file (interruption event), enabling the vibration to adapt to different scenarios while maintaining a relatively simple control structure.
Solution Approach 2:
The patent changes the vibration parameters by calculating the difference between static and dynamic description files to generate an adjustment coefficient. This coefficient is then applied to modify the driving waveform parameters (such as amplitude, frequency, or duration), allowing the system to adapt vibration characteristics to different interruption events without completely redesigning the control system.
2Ease of operation
If the driving waveform is adjusted frequently to adapt to different scenarios, then the vibration sensation experience is improved, but the linear motor may be damaged due to excessive adjustments
Solution Approach 1:
The patent applies preliminary protective measures by setting adjustment limits for the driving waveform parameters before actual adjustments occur. The system pre-defines safe adjustment ranges and monitors whether the calculated adjustment coefficients would cause parameters to exceed these limits, preventing potentially damaging adjustments before they happen.
Solution Approach 2:
The patent implements a feedback mechanism that monitors the adjustment process and provides prompt information when adjustment limits are approached or exceeded. This feedback loop allows the system to adapt vibration parameters in real-time while continuously checking against safety boundaries, ensuring that adjustments improve user experience without compromising motor reliability.

AI summary
Embodiments of this application disclose an adjustment method and apparatus for a driving waveform, a device, and a readable storage medium. In response to an interruption event, a vibration description file corresponding to the interruption event is obtained. A vibration parameter in the vibration description file corresponding to the interruption event is used to adjust a driving waveform, so that vibration of a linear motor is adapted to the interruption event, and a vibration sensation is adjusted following scenario changes, so that a vibration function is expanded, and the user is further provided with better vibration sensation experience.
