Smart Cover Segmentation for Display Power and Security
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices with protective covers lack the ability to dynamically control and enable specific portions of the display based on the cover's position, leading to inefficient power usage and potential security vulnerabilities.
Innovation Solution
A system comprising sensors and a signal transmitter within the cover that sends opening signals to the electronic device's video controller, enabling a first portion of the display while disabling a second portion, allowing for precise control of display areas based on the cover's position or user input.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the entire display is kept enabled for protection, then security and visibility are improved, but power consumption increases
Solution Approach 1:
The display is divided into multiple independent regions that can be individually enabled or disabled. The cover is segmented into multiple sections, each corresponding to a specific display region. When the cover is closed, only the display region corresponding to the opened cover section remains enabled, while other regions are disabled to save power. This segmentation allows selective activation of display portions based on cover position.
Solution Approach 2:
The system dynamically adjusts which display regions are enabled based on the real-time position of the cover. As the cover moves between closed and open states, the enabled display regions automatically update to match the cover position. This dynamic adaptation ensures that display protection and power saving are continuously optimized based on actual usage conditions.
2Ease of operation
If the entire display is kept enabled, then information accessibility is improved, but security vulnerabilities increase
Solution Approach 1:
The display is divided into multiple independent regions that can be individually enabled or disabled. The cover is segmented into multiple sections, each corresponding to a specific display region. When the cover is closed, only the display region corresponding to the opened cover section remains enabled, while other regions are disabled to save power. This segmentation allows selective activation of display portions based on cover position.
Solution Approach 2:
The cover acts as an intermediary mechanism that mediates between user access and display visibility. When the cover is in a closed position, it physically blocks access to certain display regions and simultaneously disables those regions electronically. This intermediary action ensures that even if the display is technically visible, the covered regions cannot be accessed or viewed, providing an additional layer of security.
3Device complexity
If the cover structure is simplified, then device complexity is reduced, but control precision over display areas decreases
Solution Approach 1:
The cover structure performs multiple functions simultaneously: it provides physical protection for the display, acts as a mechanical indicator of user intent, and triggers electronic control signals for display region management. The same cover components that provide structural protection also contain or trigger sensors that detect cover position and generate corresponding control signals for the display controller, eliminating the need for separate control mechanisms.
Solution Approach 2:
The cover structure is designed to automatically trigger the appropriate display control actions through its own movement and position. As the user opens or closes the cover, the cover's mechanical movement directly activates sensors or switches that generate control signals for the display controller. This self-service mechanism eliminates the need for separate buttons, switches, or software interfaces to control display regions, simplifying the overall system while maintaining precise control.

AI summary
A cover for an electronic device comprises: at least one sensor, wherein the at least one sensor detects the cover being partially opened; and a signal transmitter, wherein the signal transmitter: transmits, to a video controller in the electronic device, an opening signal in response to the cover being partially opened, wherein the opening signal is in response to the cover being partially opened, and wherein the opening signal identifies and enables a first portion of a display on the electronic device; and transmits, to the video controller in the electronic device, a disabling signal to disable a second portion of the display that is not identified by the opening signal.
