Foldable Display Power Mode Switching for Grip Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Foldable electronic devices with dual display surfaces face issues of unnecessary power consumption and erroneous operations when the rear display surface is active, as it continues to show the screen and can be accidentally touched while gripping the device.
Innovation Solution
An electronic device with a housing containing a first and second display surface, each operable in different power modes, along with sensors to detect the user's grip and state, allowing the processor to selectively activate or deactivate the display surfaces based on the device's folding or unfolding state, ensuring power-saving modes are applied to the rear surface to prevent unnecessary power usage and accidental inputs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the rear display surface continues to display a screen in a folded state, then the user can access information on the rear surface, but power is consumed unnecessarily and erroneous operations may occur from unintended touches
Solution Approach 1:
The patent implements dynamic mode switching for the rear display surface based on the device's folding state. The processor automatically transitions the rear display between different operational modes (first mode when unfolded, second mode when folded) to adapt to changing usage scenarios. This dynamic adjustment allows the system to maintain information accessibility while optimizing power consumption according to the actual physical state of the device.
Solution Approach 2:
The patent changes the operational parameters of the rear display surface by switching between multiple predefined modes. Each mode represents a distinct set of parameters including power consumption level, display activity, and touch sensitivity. The processor selects appropriate parameter sets based on folding state detection, thereby resolving the contradiction between maintaining functionality and reducing power usage.
2Duration of action of stationary object
If the rear display surface remains active in folded state, then continuous information display is maintained, but erroneous operations occur due to accidental touches while gripping
Solution Approach 1:
The patent dynamically adjusts the operational state of the rear display surface based on real-time detection of the device's folding state. When the device is detected to be in a folded state, the processor automatically transitions the rear display to a second mode that prevents touch input while maintaining display functionality. This dynamic response ensures continuous information availability while eliminating the risk of erroneous operations from accidental touches during gripping.
Solution Approach 2:
The system employs feedback from sensors that detect the folding state of the device to control the operational mode of the rear display surface. The processor continuously monitors the physical state and adjusts display behavior accordingly, creating a closed-loop control system that maintains both continuous operation and high reliability by adapting to the user's actual interaction context.
3Use of energy by moving object
If the rear display surface is deactivated in folded state, then power consumption is reduced and erroneous operations are prevented, but the user cannot access information on the rear surface
Solution Approach 1:
The patent segments the operational modes of the rear display surface into distinct, independently controllable states. The first mode enables full functionality with touch input when the device is unfolded, while the second mode provides display-only operation when folded. This segmentation allows the system to selectively activate only the necessary functions based on the folding state, thereby reducing power consumption while preserving information accessibility through appropriate mode selection.
Solution Approach 2:
The rear display surface is designed with multi-functionality, capable of operating in multiple modes to serve different purposes. In the first mode, it provides full interactive access to information when the device is unfolded. In the second mode, it maintains information display capability while preventing touch input when folded. This universal design enables the single display surface to fulfill multiple functional requirements across different usage scenarios.
4Use of energy by moving object
If multiple display modes are implemented for adaptive power management, then power efficiency is improved, but device complexity increases due to additional control logic
Solution Approach 1:
The patent implements a dynamic mode switching mechanism controlled by the processor that automatically transitions between predefined display modes based on the device's folding state. The system maintains a set of predetermined modes with distinct power consumption characteristics and functional properties. The processor dynamically selects the appropriate mode based on real-time sensor feedback, achieving power efficiency through automated adaptation without requiring complex user intervention or manual configuration.
Solution Approach 2:
The system employs self-service through automated mode selection based on the device's physical state. The processor autonomously determines the appropriate display mode by monitoring folding state sensors and automatically transitioning between predefined modes. This self-service mechanism eliminates the need for complex user interfaces or manual mode switching, thereby achieving power efficiency gains while keeping the control logic relatively simple and intuitive.
