Flip Screen Power Control via Gesture Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current power control systems for electronic devices with flip screens are inflexible, often switching to sleep mode when the screen is closed, which is inconvenient for users who want to maintain normal operation during short breaks or shut down the device when not in use.
Innovation Solution
A power control method that detects specific gestures when the user closes the flip screen, allowing the device to select from multiple power modes based on the detected gesture, such as 'no action' to maintain current mode, 'sleep', 'hibernate', or 'shutdown', using a combination of touch sensors and a processor to determine the gesture and corresponding power mode.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If the system presets to switch to sleep mode when the screen is closed, then power consumption is reduced, but user convenience deteriorates because the user cannot maintain normal operation during short breaks
Solution Approach 1:
The system dynamically adjusts the power mode based on detected gestures. Different closing gestures (e.g., closing from different directions, with or without pressing) trigger different power modes such as sleep mode, hibernate mode, or shutdown. This dynamic adaptation allows the system to optimize power consumption while respecting user intent, resolving the contradiction between energy savings and user convenience.
Solution Approach 2:
The system changes the power state parameter based on gesture detection. By detecting specific gestures during screen closing, the system selects from multiple power modes (sleep, hibernate, shutdown) rather than defaulting to a single mode. This parameter change enables flexible power management that adapts to different user scenarios.
2Extent of automation
If the system presets to switch to sleep mode when the screen is closed, then automatic power management is improved, but adaptability deteriorates because the user cannot choose different power modes for different scenarios
Solution Approach 1:
The system transitions from static automatic power management to dynamic gesture-based power management. By detecting gestures during screen closing, the system automatically selects the appropriate power mode (sleep, hibernate, or shutdown) based on user behavior patterns, thereby improving both automation and adaptability simultaneously.
Solution Approach 2:
The system incorporates gesture detection as feedback to determine power mode selection. The touch sensor detects user gestures during screen closing, and this feedback information is used to automatically select the appropriate power mode, enabling the system to adapt to different user scenarios while maintaining automatic operation.
3Adaptability or versatility
If touch sensors are added to detect gestures, then adaptability is improved, but device complexity increases
Solution Approach 1:
The touch sensor serves multiple functions: it detects closing gestures, determines closing direction, and identifies pressing actions. By making the touch sensor multi-functional, the system achieves high adaptability without proportionally increasing device complexity, as the same hardware component handles multiple detection tasks.
Solution Approach 2:
The existing touch sensor infrastructure is utilized for gesture detection during screen closing. Rather than adding completely new sensing mechanisms, the system leverages the touch sensor's inherent capabilities to detect gestures, thereby improving adaptability while minimizing the increase in device complexity.
