Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple medical devices are combined in the operating room, then the functionality and capability of the surgical system is improved, but the setup complexity and difficulty of achieving optimal configuration increases
Solution Approach 1:
The patent introduces an augmented reality device as an intermediary between the surgical team and the complex medical devices. This AR device visualizes optimal device positions and patient setup configurations, serving as a mediator that translates complex setup requirements into intuitive visual guidance, thereby reducing setup complexity while maintaining full functionality of multiple medical devices
Solution Approach 2:
The system performs preliminary actions by pre-calculating and visualizing optimal device positions and patient configurations before the surgical procedure begins. The augmented reality device displays recommended setups in advance, allowing the surgical team to prepare and adjust equipment positions beforehand, thus reducing the complexity of real-time setup adjustments during surgery
2Ease of operation
If pre-defined setups are used, then the ease of operation is improved, but the adaptability to different surgical specialties and device combinations deteriorates
Solution Approach 1:
The patent implements dynamic adaptability where the augmented reality device can adjust and provide customized setup recommendations based on different surgical specialties, patient anatomies, and device combinations. Rather than using static pre-defined setups, the system dynamically generates optimal configurations tailored to specific surgical scenarios, maintaining ease of operation while achieving high adaptability across different specialties
Solution Approach 2:
The system changes parameters by adjusting device positions, orientations, and configurations based on real-time input data including patient anatomy, surgical procedure type, and available equipment. The augmented reality device visualizes these parameter changes and their impact on surgical setup, enabling flexible adaptation to different specialties while maintaining simple operation through automated parameter optimization
3Measurement precision
If surgeons spend time correcting incorrect setups, then the measurement precision of device positioning can be improved, but the loss of time during surgical preparation increases
Solution Approach 1:
The augmented reality device provides real-time feedback on device positioning and patient setup accuracy. By visualizing the current setup alongside optimal configuration recommendations, the system enables the surgical team to immediately identify and correct positioning errors, achieving high measurement precision without significant time loss. The feedback loop allows for rapid iteration and adjustment during setup phase
Solution Approach 2:
The system performs preliminary positioning and alignment calculations before the surgical procedure begins, allowing the team to establish accurate device positions in advance. The augmented reality visualization guides the setup process step-by-step, ensuring precise positioning is achieved during preparation rather than during surgery, thereby minimizing time loss while maintaining high positioning precision

AI summary
The disclosed method encompasses using an augmented reality device to blend in augmentation information including for example atlas information. The atlas information may be display separately from or in addition to a patient image (planning image). In order to display the atlas information in a proper position relative to the patient image, the two data sets are registered to one another. This registration can serve for generating a diversity of atlas-based image supplements, for example alternatively or additionally to the foregoing for displaying a segmentation of the patient image in the augmented reality image. The disclosed method is usable in a medical environment such as for surgery or radiotherapy.
