Off-State Content Display on Electronic Paper
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Computing devices do not effectively display user-relevant content when in an inactive or off-state, failing to provide visual representations or usage metrics of actively used digital content items.
Innovation Solution
A computing device is programmed to display a user-relevant content screen with visual representations and metric information of actively used digital content items, even when in an off-state, by monitoring usage parameters and storing a content screen for display on electronic paper type displays or other mediums.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If the computing device is in an inactive or off-state, then energy consumption is reduced, but the ability to display user-relevant content is lost
Solution Approach 1:
The system prepares and stores content screens for display before the device enters off-state. Usage parameters are monitored and content is pre-rendered while the device is still active, so that when the device transitions to low-power mode, the content can be displayed without requiring active processing or energy consumption.
Solution Approach 2:
The system creates a static copy of the content screen that can be displayed in off-state. Instead of requiring the device to actively generate and refresh the display content, a static representation of the content is stored and displayed, eliminating the need for continuous energy consumption while maintaining content visibility.
2Loss of information
If the device displays content during off-state, then user engagement is maintained, but energy savings are reduced
Solution Approach 1:
The system applies different operational modes to different parts of the display system. The electronic paper display is capable of maintaining static content without power, while only minimal processing is required to monitor usage parameters and update content when needed. This localized approach allows content visibility without continuous energy consumption across the entire device.
Solution Approach 2:
Instead of continuous content generation and display refresh, the system uses periodic monitoring of usage parameters and updates content only when changes occur. The display transitions between active content updates and passive static display periods, reducing overall energy consumption while maintaining content relevance.
3Measurement precision
If usage parameters are monitored continuously, then accurate metrics are obtained, but device complexity increases
Solution Approach 1:
The system extracts only the essential usage parameters needed for content display decisions, rather than monitoring all possible device states. By focusing on specific metrics relevant to content selection and display, the monitoring system achieves accurate measurement without requiring complex comprehensive monitoring of all device operations.

AI summary
Usage of a computing device is monitored when the computing device is in an active state. A content screen is stored corresponding to a digital content item that is in use when the computing device is in the active state. In response to the computing device being placed in an inactive state, the content screen is displayed on a display of the computing device.
