Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current augmented reality (AR) systems in industrial environments face challenges in quickly connecting users to AR nodes and maintaining accurate location tracking, especially under varying lighting and weather conditions, and for users unfamiliar with the system or environment.
Innovation Solution
The AR node location and activation system allows users to quickly detect and activate AR nodes using metadata, device information, or visual cues, enabling seamless connection and improved accuracy even in poor lighting or weather conditions, without relying heavily on image processing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If image recognition and simultaneous localization and mapping technology are used to detect AR nodes, then the system can provide location tracking, but the detection speed is slow and accuracy degrades under varying lighting and weather conditions
Solution Approach 1:
The patent changes the detection parameter from visual/image-based recognition to alternative sensing methods such as RFID, NFC, Bluetooth, or audio-based detection. This parameter change allows the system to detect AR nodes without relying on lighting conditions, thereby maintaining detection accuracy and reliability under varying environmental conditions.
2Loss of information
If comprehensive 3D models with extensive information are provided to users, then users gain access to detailed device information, but users experience sensory overload and difficulty perceiving context
Solution Approach 1:
The patent applies local quality by providing different information densities to different users based on their needs and roles. The system selectively displays comprehensive 3D model information only to authorized users who require it, while providing simplified views to others, thereby preventing sensory overload while maintaining information availability for those who need it.
Solution Approach 2:
The system dynamically adjusts the level of information displayed based on user interaction, context, and authorization. The 3D model information can be expanded or collapsed, and different detail levels are provided based on user needs, allowing the information presentation to adapt rather than being static and overwhelming.
3Manufacturing precision
If manual 3D modeling procedures are used to create environment models, then accurate models can be created, but the process is very time- and labor-intensive
Solution Approach 1:
The patent uses copying by creating digital replicas of physical environments and objects using 3D scanning technology. Instead of manually modeling each object, the system captures the actual environment and objects digitally, then uses these copies to generate accurate 3D models automatically, significantly reducing time and labor while maintaining precision.
Solution Approach 2:
The patent replaces the mechanical manual modeling process with automated digital scanning and processing systems. The 3D scanning technology and automated model generation algorithms substitute for manual human effort, achieving the same modeling accuracy much faster through computational rather than mechanical means.
4Loss of information
If the entire 3D model is rendered to the user, then complete environmental information is provided, but the system cannot selectively display only relevant portions
Solution Approach 1:
The patent segments the complete 3D model into distinct, manageable portions or layers that can be selectively displayed. The system divides the environmental information into modular components that can be independently controlled, allowing the AR device to render only the relevant segments based on user location, authorization, and context, rather than displaying the entire model at once.

AI summary
An augmented reality (AR) node location and activation technique for use in an AR system in a process plant or other field environment quickly and easily detects an AR node in a real-world environment and is then able to activate an AR scene within the AR system, which improves the usability and user experience of the AR system. The AR node location and activation system generally enables users to connect to and view an AR scene within an AR system or platform even when the user is not directly at an existing AR node, when the user is experiencing poor lighting conditions in the real-world environment and in situations in which the user is unfamiliar with the AR nodes that are in the AR system database. As a result, the user can quickly and easily activate the AR system and connect to an AR scene for an AR node close to the user in the field environment under varying weather and lighting conditions in the field and without requiring a large amount of image processing to locate the correct AR scene based on photographic images provided by the user.
