Earbud-Aware Display Brightness Control for Viewing and Power Balance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices struggle to adjust display luminance effectively based on the angle formed with earbuds, leading to suboptimal viewing experiences, especially when the device and earbuds are not aligned properly.
Innovation Solution
The electronic device uses sensors to detect the posture of both the device and the earbuds, adjusts display brightness based on the alignment, and implements a lock state when alignment is lost, ensuring optimal viewing conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If the display brightness is maintained at high level continuously, then the viewing experience is good, but the power consumption increases
Solution Approach 1:
The display brightness is made dynamic by adjusting it based on the detected angle between the electronic device and earbuds. When the angle indicates proper alignment (within threshold), brightness is maintained at high level; when misaligned, brightness is reduced. This dynamic adjustment resolves the contradiction by making brightness adaptive to usage conditions.
Solution Approach 2:
The system uses sensors to detect the angle between the device and earbuds, compares it with a threshold value, and uses this feedback to automatically adjust display brightness. This closed-loop feedback mechanism ensures brightness is optimized based on actual alignment status, preventing unnecessary power consumption when earbuds are not properly positioned.
2Use of energy by moving object
If the display brightness is reduced to save power, then the power consumption decreases, but the viewing experience deteriorates
Solution Approach 1:
The brightness level is dynamically adjusted based on real-time detection of earbuds alignment. When sensors detect that the angle between device and earbuds is within the threshold (indicating proper alignment and active usage), brightness is automatically increased to provide good viewing experience. When misaligned, brightness is reduced to save power.
Solution Approach 2:
The system changes the display brightness parameter based on the detected spatial relationship (angle) between the electronic device and earbuds. By monitoring the angle parameter and comparing it with a threshold, the system automatically adjusts brightness to match the actual usage state, ensuring optimal viewing experience only when needed.
3Measurement precision
If the system continuously monitors the angle between device and earbuds, then the alignment accuracy is improved, but the device complexity increases
Solution Approach 1:
The system uses the device's existing sensors (accelerometer, gyro, magnetometer) to self-monitor the angle between the device and earbuds without requiring additional specialized sensors. The processor automatically performs angle calculation and comparison with threshold, enabling precise alignment detection using already-available components.
Solution Approach 2:
Instead of using complex mechanical alignment indicators or additional specialized sensors, the system substitutes a software-based solution that uses data from existing motion sensors (accelerometer, gyro, magnetometer) to calculate the angle and determine alignment status. This replaces potential mechanical complexity with computational simplicity.
