Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile computing devices face issues with unwanted display clearing due to screen timeouts, which can reduce battery life and inconvenience users, especially when they are actively using applications or waiting for content to load.
Innovation Solution
An apparatus and method that utilize a processor, display, and activity module based on input from non-tactile sensors to determine user activity, preventing display clearing by simulating user interaction or adjusting timers to ensure the display remains active during usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If a screen timeout timer is implemented to preserve battery life, then energy consumption is reduced, but the display may clear unintentionally during user activity
Solution Approach 1:
The system continuously monitors sensor data (accelerometer, gyroscope, proximity sensor) to detect user activity states and provides feedback to the display control logic. This feedback mechanism allows the system to dynamically adjust display timeout behavior based on real-time detection of whether the user is actively using the device, thereby preventing premature display clearing while maintaining battery efficiency.
Solution Approach 2:
The display timeout system transitions from a static, fixed-timeout approach to a dynamic, adaptive approach. The timeout duration and activation are dynamically adjusted based on real-time sensor inputs that detect user presence and activity state. This allows the system to extend or suspend timeouts when user activity is detected, resolving the contradiction between energy saving and accurate user state recognition.
2Ease of operation
If the display disable timer is disabled to prevent unwanted clearing, then user convenience is improved, but battery life is significantly reduced
Solution Approach 1:
The system uses sensor feedback to intelligently determine when to maintain display activity versus when to activate timeout for energy saving. By continuously monitoring accelerometer, gyroscope, and proximity sensor data, the system can distinguish between active user usage and idle states, automatically adjusting display behavior to provide convenience during usage while preserving battery life during idle periods.
Solution Approach 2:
The system autonomously manages display timeout behavior without requiring explicit user intervention. It self-adjusts the display state based on sensor-detected user activity patterns, eliminating the need for users to manually disable or configure timeout settings while achieving both convenience and energy efficiency.
3Reliability
If the display remains active longer to prevent clearing during user activity, then user experience is improved, but power consumption increases
Solution Approach 1:
The system dynamically adjusts display active state based on real-time sensor analysis. When user activity is detected through accelerometer, gyroscope, or proximity sensor inputs, the system extends or suspends display timeout to maintain availability. When no activity is detected, the system activates timeout to reduce power consumption, thus dynamically balancing display availability and energy loss.
Solution Approach 2:
The system changes the timeout parameter adaptively based on detected user activity state. Instead of using a fixed timeout value, the system modifies the timeout duration or activation status according to sensor data, thereby optimizing the balance between maintaining display availability and minimizing energy consumption under different usage conditions.
