Solution Overview
Problem
Existing electronic devices with vibration units struggle to control vibrations effectively based on the device's state, particularly when generating vibrations from audio signals, which can interfere with wireless charging efficiency and user experience.
Innovation Solution
An information processing apparatus with a control unit that manages the vibration unit based on various conditions, including screen state, content type, and device position, to restrict or adjust vibrations for improved charging efficiency and user interaction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the vibration device generates vibration based on audio signal, then user experience is improved through synchronized haptic feedback, but wireless charging efficiency deteriorates due to interference between vibration and charging operations
Solution Approach 1:
The system dynamically adjusts vibration operation based on charging state. When wireless charging is detected, the control unit restricts or modifies vibration generation to prevent interference with charging efficiency. This dynamic adaptation allows the device to optimize both user experience and charging performance under different operating conditions.
Solution Approach 2:
The control unit changes vibration parameters (amplitude, frequency, or duration) based on the charging state. By modifying vibration parameters when wireless charging is active, the system reduces negative interference while maintaining acceptable haptic feedback for user interactions, thus balancing user experience with charging efficiency.
2Loss of energy
If vibration is restricted during wireless charging, then charging efficiency is improved, but user experience deteriorates due to loss of haptic feedback for notifications
Solution Approach 1:
The system applies different vibration strategies to different notification types during wireless charging. Critical notifications may receive restricted vibration feedback while less important ones are suppressed entirely. This localized differentiation maintains essential user experience while minimizing interference with charging operations.
Solution Approach 2:
The control unit acts as an intermediary between the vibration device and the charging system. It mediates by selectively enabling or modifying vibration based on notification priority and charging state, providing a compromise solution that partially maintains haptic feedback while protecting charging efficiency.
