Electronic Device Orientation-Based Display and Notification Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for electronic devices, such as mobile phones, to efficiently manage power consumption and user notification based on orientation, as existing devices struggle to balance display functionality with power efficiency and privacy when the device is oriented in different positions.
Innovation Solution
The implementation of an electronic device with a first and second surface, a display unit on the first surface, a notification unit on the second surface, and attitude detecting and shielded-state detecting units that adjust the display and notification modes accordingly, preventing power consumption and allowing notifications when the device is oriented in specific ways.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the display unit is always kept on to provide information to the user, then the user can access information conveniently, but the power consumption increases
Solution Approach 1:
The display unit dynamically changes its state based on device orientation. When the device is in pocket mode (detected by attitude detecting unit), the display remains off to save power. When the device is taken out and oriented for use, the display turns on automatically. This dynamic adaptation resolves the contradiction between continuous information accessibility and power consumption.
Solution Approach 2:
The system changes the operational parameter of the display unit (on/off state) based on detected orientation parameters. The attitude detecting unit monitors orientation parameters, and when specific threshold values are exceeded indicating pocket mode, the display parameter is changed to off state, reducing power consumption while maintaining usability when needed.
2Use of energy by moving object
If the display unit is turned off to reduce power consumption, then power efficiency improves, but the user cannot receive notifications or access information
Solution Approach 1:
The notification unit acts as an intermediary between the system and the user when the display is off. It provides tactile or audible notifications to alert the user of incoming information without requiring the display to be active. This intermediary mechanism ensures notification delivery is maintained while the display remains off to preserve power efficiency.
Solution Approach 2:
The information delivery function is segmented into two independent channels: the display unit for detailed information presentation and the notification unit for alerting the user. When power saving mode is active, the display channel is deactivated while the notification channel remains operational, ensuring that users are still informed of new information without the energy cost of running the display.
3Loss of information
If the display unit is made visible to the user, then information is presented clearly, but user privacy is compromised when the device is in certain orientations
Solution Approach 1:
The display unit dynamically adjusts its visibility based on device orientation. When the attitude detecting unit determines the device is in a private orientation (e.g., facing downward in a pocket), the display automatically turns off or switches to a private mode, preventing unintended viewing. When the device is oriented for legitimate use, the display becomes visible again, ensuring information is presented clearly only when appropriate.
Solution Approach 2:
The system preemptively activates private mode or turns off the display when it detects orientations that could compromise privacy, such as when the device is placed face-down in a pocket. This preliminary anti-action prevents privacy exposure before it can occur, while still allowing full display functionality when the device is properly positioned for use.

AI summary
According to an aspect, an electronic device includes a first face, a second face, a display unit arranged on the first surface, a notification unit arranged on the second surface, an attitude detecting unit, and a control unit. The attitude detecting unit detects whether attitude of the electronic device is a first attitude, in which the first surface faces upward in the vertical direction, or a second attitude, in which the first surface faces downward in the vertical direction. When the attitude detecting unit detects the second attitude, the control unit prevents displaying on the display unit and enables the notification unit to give a notification.
