Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If traditional CPR systems with audible feedback are used, then basic guidance can be provided, but real-time spatially-accurate guidance and coordination between multiple providers cannot be achieved
Solution Approach 1:
The system implements real-time feedback by capturing CPR performance data through sensors, processing it to determine quality metrics, and immediately displaying visual feedback through the augmented reality device. This closed-loop feedback system allows providers to adjust their techniques based on real-time performance data, directly addressing the information loss problem while managing complexity through automated processing.
Solution Approach 2:
The patent replaces traditional mechanical/audio feedback systems with an optical/electronic augmented reality system. Instead of using simple audible cues from defibrillators, the system uses cameras, processors, and AR displays to provide comprehensive visual feedback, substituting mechanical signal processing with electronic image processing and spatial rendering.
2Productivity
If multiple acute care providers perform CPR simultaneously, then comprehensive patient care can be provided, but coordination and quality monitoring between providers becomes difficult
Solution Approach 1:
The augmented reality system serves multiple functions simultaneously: it monitors individual provider performance, tracks patient response, coordinates team actions, and provides real-time feedback to each provider. This multi-functional system addresses the coordination challenge by consolidating multiple monitoring and communication functions into a single integrated platform that all providers can access.
Solution Approach 2:
Each provider receives personalized real-time feedback about their specific performance metrics through their own AR device, while the system also provides coordinated team feedback. This multi-level feedback mechanism allows individual performance tracking while maintaining overall team coordination, solving the information loss problem for individual providers without compromising team productivity.
3Measurement precision
If visual display is added to provide real-time feedback, then CPR quality guidance improves, but device complexity and information processing requirements increase
Solution Approach 1:
The system replaces simple audio feedback mechanisms with comprehensive visual display systems that process image data from multiple cameras. This substitution enables precise measurement of CPR performance by analyzing visual data, though it increases complexity. The patent manages this by integrating the processing into the existing AR device architecture rather than adding separate processing systems.
Solution Approach 2:
The system transitions from one-dimensional audio feedback to multi-dimensional visual feedback by incorporating spatial information, color coding, and graphical overlays in the augmented reality display. This dimensional enhancement provides more precise measurement and guidance information, managing complexity through efficient use of the AR display's inherent multi-dimensional capabilities.

AI summary
A spatially sensitive augmented reality system for providing resuscitative feedback in a mixed reality environment to an acute care provider during occurrence of a cardiac event in a patient includes a wearable augmented reality device having at least one three-dimensional sensor, a visual display for viewing by the acute care provider, and at least one processor. The at least one processor is configured to receive and process three-dimensional information of a scene of the cardiac event; produce a three-dimensional representation of a field of view of the acute care provider based on the processed three-dimensional information; identify one or more physical objects associated with the cardiac event in the three-dimensional representation; generate at least one virtual three-dimensional object within the three-dimensional representation; and generate an image of the virtual three-dimensional object within the three-dimensional representation on the visual display.
