Engineering Contradiction Analysis
1Power
If additional processing resources are integrated into XR presentation systems, then computing capability is improved, but device weight increases
Solution Approach 1:
The patent extracts heavy processing resources from the wearable XR device and relocates them to remote cloud computing systems. The XR device retains only essential local processing for immediate responsiveness, while computationally intensive tasks are offloaded to external servers, thereby achieving high computing capability without increasing device weight
Solution Approach 2:
The patent introduces a communication subsystem as an intermediary between the XR device and remote processing resources. This intermediary enables the device to access powerful external computing resources through wireless communication, allowing the device to maintain lightweight design while still leveraging remote processing power for complex XR computations
2Power
If additional processing resources are integrated into XR presentation systems, then computing capability is improved, but device bulkiness increases
Solution Approach 1:
The patent removes bulky processing components from the wearable device by extracting them to remote cloud infrastructure. This extraction eliminates the need for large local processing units, power supplies, and associated cooling systems within the device, thereby maintaining compact form factor while accessing high computing capability through networked resources
3Power
If additional processing resources are integrated into XR presentation systems, then computing capability is improved, but battery life is reduced
Solution Approach 1:
The patent extracts power-intensive processing tasks from the local device and relocates them to remote servers with unlimited power supply. By performing computationally heavy XR rendering, physics simulation, and AI processing remotely, the device minimizes its own power consumption, thereby extending battery life while maintaining high computing capability for immersive experiences
4Power
If additional processing resources are integrated into XR presentation systems, then computing capability is improved, but heat dissipation problems worsen
Solution Approach 1:
The patent extracts heat-generating processing operations from the wearable device and moves them to remote data centers with adequate cooling infrastructure. By offloading intensive computations such as real-time rendering, physics calculations, and neural network inference to external systems, the device generates minimal heat, eliminating the need for complex cooling mechanisms and ensuring comfortable wearability

AI summary
An extended reality (XR) support system establishes a communicative link between an XR presentation system and a multi-access edge compute (MEC) system operating on a cellular network. The XR support system identifies a parameter associated with a computing task to be performed in connection with an XR experience presented by the XR presentation system. The XR support system also identifies a condition associated with a capability of the XR presentation system or the MEC system to perform the computing task. Based on the identified parameter and the identified condition, the XR support system selects at least one of the XR presentation system or the MEC system to perform the computing task and then directs the selected system to perform the computing task. Corresponding methods and systems are also disclosed.
