Solution Overview

Problem

Current electronic devices with fixed vibration modes provide a uniform vibration experience, which is not adaptable to different application scenes or screen directions, leading to a poor user experience.

Innovation Solution

The implementation of a vibration method that adjusts the vibration mode of electronic devices based on the screen direction, utilizing at least two motors that change their vibration waveforms in response to changes in the screen direction, thereby enhancing the user experience by providing a more dynamic and relevant vibration feedback.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a fixed vibration mode is used in the motor, then the device structure is simple, but the user experience is poor because the vibration effect is the same in any scene

Engineering Contradiction:
Improvevibration adaptability to different scenesVSAvoiddevice complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent implements dynamic vibration modes by allowing the motor to switch between different vibration waveforms (first waveform and second waveform) depending on the screen direction. When the screen direction changes from first to second direction, the vibration waveform automatically switches to provide appropriate vibration feedback for different application scenes, making the system adaptive without requiring multiple fixed vibration motors.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent changes the vibration parameters (waveform type) of the motor based on screen direction. By detecting the screen direction and corresponding the first screen direction to a first vibration mode and the second screen direction to a second vibration mode, the system dynamically adjusts vibration parameters to improve user experience across different scenes while maintaining a simple single-motor structure.

Inventive Principle:
Principle #35Parameter changes

2Ease of operation

If the screen direction is switched from the first screen direction to a second screen direction, then the positions of the motors change relative to the interface scene, but the vibration mode needs to be adjusted to maintain consistent user experience

Engineering Contradiction:
Improveuser experience consistencyVSAvoidvibration control complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent implements a feedback mechanism where the system detects the screen direction (first or second direction) and automatically corresponds it to the appropriate vibration mode (first or second vibration mode). This feedback loop ensures that the vibration effect remains consistent and appropriate for the current interface scene, improving ease of operation without requiring complex manual adjustment.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The vibration mode dynamically adapts to screen direction changes. When the screen direction switches from first to second direction, the vibration waveform automatically switches from the first vibration mode to the second vibration mode, ensuring that the vibration feedback remains appropriate for the current interface orientation without requiring additional control complexity.

Inventive Principle:
Principle #15Dynamics

AI summary

This application provides a vibration method and apparatus, an electronic device, and a readable storage medium. The method includes: In response to a first operation, the electronic device enters a first application scene, where the electronic device includes at least two motors; in response to that the electronic device enters the first application scene, and a screen direction of the electronic device is a first screen direction, the at least two motors vibrate in a first vibration mode; and in response to a second operation, the screen direction of the electronic device is switched from the first screen direction to a second screen direction, and the at least two motors vibrate in a second vibration mode, where the first vibration mode is different from the second vibration mode. In this embodiment of this application, a vibration mode of a motor may be changed to adapt to the screen direction of the electronic device, so as to achieve an effect of adapting to a vibration feeling of a user based on the screen direction, thereby improving user experience.
