Display Control for Foldable Case Privacy
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Foldable cell-phones allow information intended to be private to be easily visible to others when in a closed state, compromising user privacy.
Innovation Solution
A display control device that detects the inclination of a foldable cell-phone and determines which display unit is visible to the user, outputting only authorized information to that unit to prevent unauthorized viewing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If multiple display units are arranged on different surfaces of a foldable case to enable visibility in closed state, then user convenience is improved, but information privacy is compromised
Solution Approach 1:
The patent applies local quality by detecting the inclination of each display unit individually and determining visibility status for each specific display unit based on its local orientation. The control unit then selectively outputs display data only to display units that are determined to be visible to the user, thereby applying different display behaviors to different local positions (display units) based on their specific inclination angles and visibility conditions.
2Loss of information
If display data is output to all display units regardless of visibility, then information completeness is improved, but unauthorized viewing risk increases
Solution Approach 1:
The patent implements feedback by using the inclination detection unit to continuously monitor the angle of each display unit and feed this information back to the control unit. The control unit then uses this feedback to dynamically determine which display units are visible to the user and adjusts the display data output accordingly, creating a closed-loop system that adapts to changing device orientations and user viewing conditions.
3Ease of operation
If display units are made visible in closed state for convenience, then accessibility is improved, but security against peeking deteriorates
Solution Approach 1:
The patent applies dynamics by making the display visibility dynamic rather than static. Display units are dynamically adjusted based on real-time inclination detection - they are activated when determined to be visible to the user and deactivated or obscured when not visible. This dynamic control allows the system to provide accessibility when needed while maintaining security when the device is in positions where unauthorized viewing is possible.

AI summary
A display control device (500) is the display control device (500) that controls output of display data to a plurality of display units that are arranged on different surfaces of a case, comprising a posture detection unit (510), a visibility state determination unit (520), and a display data output unit (530). The posture detection unit (510) detects a posture of the case. The visibility state determination unit (520) determines a display unit that is visually recognizable to the user from among the plurality of display units according to the posture of the case detected by the posture detection unit (510). The display data output unit (530) outputs the display data to the display unit that the visibility state determination unit (520) determined as visually recognizable to the user.
