Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If users study and remember setup information from multiple user manuals, then they can arrange medical devices according to requirements, but the complexity of operation increases and time is lost
Solution Approach 1:
The system enables self-service by automatically detecting the spatial poses of medical devices using sensors and tracking systems, and providing real-time guidance feedback without requiring users to manually consult multiple user manuals. The computational core autonomously processes scene data and constraint data to generate guidance information.
Solution Approach 2:
The patent replaces the mechanical process of manually studying and remembering setup information with an automated computational system. Sensors, tracking systems, and a computational core substitute for human cognitive processes, automatically determining spatial relationships and providing guidance through augmented reality displays.
2Productivity
If users manually arrange medical devices based on remembered information, then device placement can be completed, but errors occur and time is consumed for correction
Solution Approach 1:
The system implements continuous feedback by monitoring the spatial poses of medical devices through sensors and tracking systems, comparing actual positions against constraint data, and providing real-time guidance feedback through augmented reality displays. This closed-loop feedback mechanism prevents errors and guides correct placement.
Solution Approach 2:
The system performs preliminary action by pre-defining constraint data that specifies correct spatial relationships between medical devices before the arrangement process begins. The guidance system proactively indicates correct positions and orientations before users complete the placement, preventing errors rather than correcting them afterward.
3Measurement precision
If real-time guidance is provided through augmented reality displays, then arrangement accuracy improves, but device complexity and system complexity increase
Solution Approach 1:
The system achieves universality by using a multi-functional integrated platform that combines sensor data acquisition, tracking system integration, computational core processing, and augmented reality display in a single guidance system. This unified system handles multiple functions through modular components, reducing overall complexity despite the sophisticated capabilities.
Solution Approach 2:
The augmented reality display acts as an intermediary that translates complex spatial relationship data and constraint information into intuitive visual guidance overlays. This intermediary layer simplifies the interface between the complex computational system and the user, presenting only essential guidance information without exposing underlying system complexity.
4Reliability
If multiple objects are arranged with spatial constraints, then compliance with requirements improves, but the time required for arrangement increases
Solution Approach 1:
The system maintains continuity of useful action by providing continuous real-time guidance throughout the entire arrangement process. Rather than requiring discrete checking steps or post-placement verification, the guidance system operates continuously, constantly updating spatial detection and providing feedback as users move devices into position, eliminating idle time and ensuring continuous progress toward correct arrangement.

AI summary
Disclosed is a method for providing guidance to a user on where to arrange an object of interest in an operating room. The method includes obtaining a spatial pose of an item arranged within the operating room and obtaining a requirement on a spatial relationship between an object of interest and the item. The method also includes determining (a) a first spatial portion in which the object of interest is recommended to be arranged, the first spatial portion being larger than the object of interest, and/or (b) a second spatial portion in which the object of interest is not allowed to be arranged. Moreover, the method includes triggering display of a visualization of the first and/or second spatial portion to guide a user on where to arrange the first object of interest in the operating room.
