Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If traditional trial lenses and phoropters are used for vision correction simulation, then the device complexity is low and ease of operation is high, but the simulation realism and patient understanding are limited
Solution Approach 1:
The patent creates virtual copies of real-world environments and visual scenes that patients can interact with through AR/VR headsets. These digital twins replicate actual viewing conditions, allowing patients to experience how vision correction will perform in their specific daily environments rather than through abstract lens trials.
Solution Approach 2:
The system introduces a computational intermediary layer that processes patient-specific visual data, environmental parameters, and optical correction models to generate personalized simulation scenarios. This intermediary translates complex optical concepts into immersive visual experiences that patients can intuitively understand.
2Reliability
If immersive AR/VR simulations are implemented, then patient understanding and simulation realism are improved, but the device complexity and synchronization requirements increase
Solution Approach 1:
The patent merges multiple subsystems (AR/VR display, head tracking, scene rendering, optical modeling) into a unified simulation platform. By integrating these components and establishing centralized synchronization protocols, the system manages complexity while delivering accurate, coordinated visual feedback that adapts to patient movements in real-time.
Solution Approach 2:
The system implements continuous feedback loops where head position and orientation data are constantly monitored and used to adjust the simulated visual scenes in real-time. This feedback mechanism ensures the simulation accurately reflects the patient's actual viewing conditions and maintains synchronization between physical movements and virtual visual feedback.
3Adaptability or versatility
If personalized visual scenes and manipulation criteria are used, then the adaptability and patient-specific accuracy are improved, but the computational requirements and processing time increase
Solution Approach 1:
The system performs preliminary processing by pre-computing patient-specific optical parameters, pre-loading relevant visual scenes, and pre-configuring manipulation criteria based on initial patient data. This preparation work is done before the actual simulation session, reducing real-time computational burden and enabling faster, more responsive personalized simulations.
Data Source
AI summary
The present disclosure relates to a patient simulation system. The patient simulation includes a processor and a computer-readable medium storing instructions which, when executed by the processor, cause the processor to receive a selection of criteria for generating a patient simulation; generate a first view of the patient simulation corresponding to the selection of criteria to be viewed in two dimensions using a clinician display; generate a second view of the patient simulation corresponding to the selection of criteria to be viewed in three dimensions using a patient display; transmit the second view of the patient simulation to the patient display; and synchronize the first view to the second view by tracking a position and head orientation of the patient.
