Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If real-time AR information is provided to mobile devices in dynamic structural environments, then situational awareness and safety are improved, but system complexity and computational requirements increase
Solution Approach 1:
The system divides the complex task of AR information delivery into separate functional modules: a server component that manages data processing and AR information assembly, and a mobile device component that handles camera capture, pose determination, and display. This segmentation reduces the computational burden on individual devices while maintaining system-wide safety and reliability.
Solution Approach 2:
The patent introduces a server as an intermediary between the complex structural environment sensors and the mobile user devices. The server acts as a mediator that receives raw sensor data, processes it, assembles appropriate AR information, and transmits it to mobile devices. This intermediary approach simplifies the architecture by centralizing complex processing tasks.
2Loss of information
If AR information is updated in real-time to reflect changing environmental conditions, then information accuracy is improved, but data transmission requirements and network bandwidth increase
Solution Approach 1:
The system implements selective AR information assembly by the server, providing only the specific portions of information that are relevant to each user's current context, location, and task. Rather than transmitting complete environmental data sets to all devices, the server filters and assembles partial information sets tailored to individual user needs, reducing overall data transmission volume while maintaining information accuracy for each user.
3Loss of information
If detailed lift parameters and environmental data are displayed to operators, then operational awareness is improved, but information processing time and cognitive load increase
Solution Approach 1:
The AR information assembly process applies local quality by customizing the information display based on each user's specific context, location, and operational role. The server determines what information is most relevant to each user and assembles personalized AR overlays that highlight only the critical parameters for that particular user's current task. This approach maintains comprehensive operational awareness while reducing cognitive load by filtering out irrelevant information.

AI summary
A method for providing information associated with a lift process to a mobile device user is presented. The method comprises receiving a request for lift environment information from a mobile device, determining a pose of the mobile interface device relative to a lift process target area, and obtaining lift environment information for at least a portion of the lift process target area. The lift environment information is used to assemble AR lift information for transmission to and display on the mobile interface device. The AR lift information is configured for viewing in conjunction with a real-time view of the lift process target area captured by the mobile interface device. The AR lift information is then transmitted to the mobile interface device for display.
