Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing AR applications for industry use cases, such as quality assurance and maintenance, are cumbersome and time-consuming, prone to errors, and require manual updates when instructions or materials change.
Innovation Solution
A method using augmented reality and a 3D model of a physical object to identify places of interest by aligning the 3D model with the physical object, tracking user gestures, and using virtual proximity sensors to determine intersection points, allowing for intuitive editing and categorization of these points.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If paper manuals or fixed monitors with media type manuals are used to assist service technicians, then instructions can be provided, but the process becomes cumbersome and time-consuming
Solution Approach 1:
The patent replaces traditional mechanical information delivery systems (paper manuals, fixed monitors) with an augmented reality system that overlays digital information directly onto the physical object. This substitution eliminates the need for technicians to physically handle manuals or switch between multiple devices, making the information retrieval process more efficient and less time-consuming while maintaining ease of operation
Solution Approach 2:
The patent creates a virtual copy of the physical object in 3D space that can be manipulated and annotated independently. This virtual model serves as a dynamic replica that technicians can interact with using natural gestures, eliminating the need to physically manipulate traditional manuals while providing the same informational functionality in a more efficient manner
2Adaptability or versatility
If traditional manual updating processes are used when instructions or materials change, then information can be updated, but it takes a lot of time to reflect changes
Solution Approach 1:
The patent implements a dynamic system where the virtual 3D model and its associated information can be updated in real-time without requiring physical reprinting or reconfiguration. When instructions or materials change, the digital content can be modified and immediately reflected in the augmented reality overlay, making the system highly adaptable to changes while eliminating the time-consuming update process of traditional manuals
Solution Approach 2:
The patent creates a universal platform that can display various types of information (instructions, materials, annotations) in a single integrated system. This multi-functional approach allows different types of content to be updated through a common interface, increasing adaptability to changes while reducing the overall time required to reflect updates across multiple information sources
3Reliability
If service technicians use paper manuals or fixed monitors, then they can complete tasks, but the process is prone to errors if protocoling has gone wrong
Solution Approach 1:
The patent incorporates feedback mechanisms where the system tracks user interactions with the virtual model and provides real-time validation. The system can detect when protocols are being followed correctly and alert users to potential errors, thereby improving reliability by reducing human error while maintaining operational simplicity through intuitive gesture-based interaction and clear visual feedback
