Solution Overview

Problem

Wireless communications networks face challenges in providing low latency, high data rates, and ultra-reliable connectivity to extended reality (XR) devices, which are essential for immersive experiences, due to network congestion, bandwidth saturation, and poor hardware performance, leading to issues like motion-to-photon-delay exceeding 20 ms and user disorientation.

Innovation Solution

Output notifications on XR devices based on real-time measurements of beam or wireless connection conditions, suggesting actions to adjust connectivity, such as changing direction, position, or connectivity technology, to maintain or improve wireless connectivity and meet key service requirements.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Area of stationary object

If wireless communications systems operate in complex and dynamic environments, then coverage area and number of devices accessing the system increase, but signal attenuation and blocking occur leading to reduced reliability and performance

Engineering Contradiction:

Improvecoverage areaVSAvoidwireless connection reliability

Core Design Contradiction:

Area of stationary objectVSReliability

Solution Approach 1:

The system dynamically adjusts wireless connectivity parameters based on real-time environmental conditions. The notification system monitors connection quality metrics and automatically generates adjustment recommendations, allowing the system to adapt to changing environmental factors such as signal attenuation and blocking, thereby maintaining reliable connections across expanded coverage areas.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The patent implements a feedback mechanism where the system monitors wireless connection conditions and provides notifications to users about optimal connectivity adjustments. This closed-loop feedback allows the system to detect degradation in connection reliability and guide users to take actions that restore optimal performance, resolving the contradiction between expanded coverage and maintained reliability.

Inventive Principle:

Principle #23Feedback

2Adaptability or versatility

If wireless communications systems support multiple users by sharing resources, then the number of devices accessing the system increases, but network congestion and bandwidth saturation occur leading to reduced data rates and increased latency

Engineering Contradiction:

Improvenumber of devices accessing systemVSAvoiddata rate

Core Design Contradiction:

Adaptability or versatilityVSProductivity

Solution Approach 1:

The notification system provides targeted connectivity adjustment recommendations to specific users experiencing degradation, rather than requiring all users to modify their connections. This partial action approach allows the system to support multiple users simultaneously while maintaining high data rates for those who need adjustments, avoiding unnecessary congestion from universal reconfiguration.

Inventive Principle:

Principle #16Partial or excessive action

Solution Approach 2:

The system monitors key performance parameters such as data rate, latency, and connection quality, and generates notifications when parameter thresholds are exceeded. By changing connectivity parameters selectively based on monitored performance metrics, the system maintains high productivity for active users while supporting a large number of devices in the network.

Inventive Principle:

Principle #35Parameter changes

3Speed

If wireless communications systems prioritize high data rates for XR devices, then immersive experience quality improves, but latency increases and connection reliability decreases due to network congestion

Engineering Contradiction:

Improvedata rateVSAvoidlatency

Core Design Contradiction:

SpeedVSLoss of time

Solution Approach 1:

The notification system proactively monitors connection conditions and provides adjustment recommendations before latency and reliability degradation become severe. By taking preliminary action to alert users of impending connectivity issues, the system allows for preventive adjustments that maintain high data rates while avoiding the latency penalties associated with reactive reconnection or extensive troubleshooting.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system enables rapid connectivity adjustments by providing clear, actionable notifications that allow users to quickly modify their connection settings. This rushing through the adjustment process minimizes the time users spend in degraded connection states, thereby reducing latency impact while maintaining the high data rates necessary for immersive XR experiences.

Inventive Principle:

Principle #21Skipping (Rushing through)
