Solution Overview
Problem
Current electronic devices lack the ability to seamlessly integrate audio subsystems with electrochromic battery covers to change colors in synchronization with audio rhythms, posing a challenge in enhancing user experience through visual-auditory interactions.
Innovation Solution
A method is introduced where an electronic device's application sends audio data through various layers to process color change data, using an audio rhythm identification algorithm to drive the battery cover to change colors in accordance with audio rhythms, allowing users to control the color change function and enabling visual reminders during events like incoming calls or alarms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If an electrochromic material is applied to the battery cover to enable color change, then the visual interaction and aesthetics are improved, but the device complexity increases due to integration with audio subsystem
Solution Approach 1:
The patent introduces an audio rhythm identification algorithm as an intermediary component that bridges the audio subsystem and the electrochromic material. This algorithm processes audio data, extracts rhythm information, and generates control signals for the battery cover, thereby simplifying the overall system integration while maintaining the desired color change functionality synchronized with audio rhythms
2Ease of operation
If the battery cover changes colors in real-time with audio rhythms, then the user interaction and visual experience are enhanced, but the energy consumption increases
Solution Approach 1:
The patent implements periodic action by synchronizing the battery cover color changes with the rhythmic patterns of audio playback. Instead of continuous color changes, the system updates colors at specific rhythmic intervals extracted from the audio signal, thereby reducing unnecessary energy consumption while maintaining the visual-auditory synchronization effect
Solution Approach 2:
The system dynamically adjusts the color change parameters (such as change frequency and intensity) based on the extracted audio rhythm characteristics. By adapting these parameters to match the audio content, the system optimizes energy consumption while preserving the desired user interaction experience across different audio scenarios
