Solution Overview
Problem
Existing mobile devices often disable motor vibration when the battery's loading capability is low, leading to a poor user experience due to the lack of touch feedback and vibration prompts.
Innovation Solution
A motor vibration control method that dynamically adjusts the motor vibration power consumption by switching to a motor vibration waveform with low power consumption or altering the motor vibration input voltage based on the battery's power supply capability, temperature, and level.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If motor vibration is enabled when battery loading capability is low, then user experience is improved, but power failure risk increases
Solution Approach 1:
The patent dynamically adjusts motor vibration parameters based on real-time battery status detection. The system switches between different vibration modes (normal mode and power-saving mode) according to battery loading capability, temperature, and level, enabling motor vibration even when battery loading capability is low while preventing power failure through adaptive parameter adjustment
Solution Approach 2:
The patent changes motor vibration parameters including waveform type, input voltage, and duration based on battery status. When battery loading capability is low, the system switches to waveforms with lower peak current requirements and adjusts input voltage to reduce power consumption while maintaining vibration functionality
2Use of energy by moving object
If motor vibration parameters are adjusted according to battery temperature and level, then power consumption is reduced, but vibration effectiveness may deteriorate
Solution Approach 1:
The patent applies different vibration parameter settings tailored to specific battery status conditions. Instead of uniformly reducing vibration parameters, the system selectively adjusts waveform type, voltage, and duration based on the degree of battery constraint, preserving vibration effectiveness within acceptable power consumption limits
Solution Approach 2:
The system uses multiple vibration waveforms with varying intensity levels. When battery loading capability is low, it selects waveforms that provide partial vibration effectiveness rather than complete disablement, or applies excessive vibration duration with lower intensity to achieve cumulative vibration effect

AI summary
This application provides a motor vibration control method and an electronic device (100), and relates to the field of terminal technologies. This can implement vibration of a motor (191) when a loading capability of a battery (142) is low. The method includes: A battery status is obtained when a first motor vibration waveform vibration request is received. The battery status includes a battery temperature, a battery temperature and a battery level, or a battery power supply capability. A motor vibration parameter is switched if the battery status meets a preset condition, where the preset condition is that the battery power supply capability is lower than a first threshold, the battery temperature is lower than a second threshold, or the battery temperature and the battery level are lower than a third threshold array. The motor vibration parameter includes a motor vibration waveform or a motor vibration input voltage. The motor (191) is driven to vibrate based on a switched motor vibration parameter.
