Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If transmit equalization waveforms are used in XR devices, then communication quality is improved, but processing complexity and power consumption increase
Solution Approach 1:
The patent introduces a companion device (UE) as an intermediary to perform the complex transmit equalization processing. The XR device delegates the generation and application of equalization waveforms to this external device, allowing the XR device to maintain low processing complexity while still achieving improved communication quality through the equalization waveforms generated by the companion device.
2Reliability
If transmit equalization waveforms are used in XR devices, then communication quality is improved, but power consumption increases
Solution Approach 1:
The companion device acts as a power-offloading intermediary, performing the computationally intensive equalization waveform generation and processing. This allows the XR device to achieve improved communication quality without bearing the associated power consumption burden, effectively transferring the energy cost to the companion device with sufficient power resources.
3Productivity
If high form factor processing is used in XR devices, then processing capability is improved, but device portability and user comfort deteriorate
Solution Approach 1:
The patent extracts the heavy processing functions from the XR device and relocates them to a separate companion device. This extraction allows the XR device to maintain a compact, lightweight form factor suitable for user comfort, while still accessing high processing capability through the external companion device that handles equalization waveform generation and processing.
