Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wearable devices face significant battery drain due to high power consumption from continuous channel monitoring for digital content delivery, leading to reduced battery life and potential quality degradation of reality-based content.
Innovation Solution
Implementing a predictive content management system that utilizes discontinuous reception (DRX) and generates predictive consumable content based on user movement, stacking content for delivery during active DRX periods, and allocating bandwidth resources to maintain quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If continuous channel monitoring is implemented for digital content delivery, then content delivery reliability is improved, but battery power consumption increases
Solution Approach 1:
The patent implements discontinuous reception (DRX) cycles where the wearable device alternates between active monitoring periods and sleep periods. During DRX active times, the device monitors channels for content delivery; during DRX sleep times, monitoring is suspended to conserve battery power. This periodic action resolves the contradiction by maintaining reliability during active periods while reducing energy consumption during sleep periods.
2Manufacturing precision
If high-quality digital content is delivered to wearable devices, then content quality is improved, but battery power consumption increases
Solution Approach 1:
The system performs predictive content management by pre-processing and preparing high-quality content during periods when the wearable device is not actively consuming power. Content is predicted based on user behavior patterns and prepared in advance, then delivered during DRX active times. This preliminary action allows high-quality content delivery without requiring continuous high-power processing on the wearable device.
3Duration of action of moving object
If battery power consumption is reduced, then battery life is extended, but content quality degrades
Solution Approach 1:
The patent introduces a predictive content management system as an intermediary between the content source and the wearable device. This intermediary pre-processed content predictions on a server or edge device, then delivered pre-processed results to the wearable during low-power DRX periods. The intermediary handles the computationally intensive quality enhancement tasks externally, allowing the wearable to maintain high content quality while operating in low-power mode.

AI summary
The present disclosure generally relates to improving energy efficiency of reality-based headsets by enabling discontinuous transmission (DRX) without significantly reducing the quality of experience (QoE) of a user of the headsets when consuming digital content presented thereon. The present disclosure includes a predictive content management system that obtains consumable content (including predictive content) to be consumed on a wearable UE. The system receives, from a radio access network (RAN), discontinuous reception (DRX) configuration information indicating active and inactive periods with which the UE and RAN may communicate. The system additionally facilitates stacking consumable content, delivering the consumable content based on the DRX configuration information, and performing certain latency masking features to avoid loss of quality of the presented content.
