Solution Overview
Problem
Static visual aids and manual validation are inadequate for assembling complex or large-sized products, as they fail to provide dynamic validation and clearance during the assembly process, leading to challenges in ensuring correct sequence and ergonomic positioning of components.
Innovation Solution
The integration of Augmented Reality (AR) and Virtual Reality (VR) technologies using wearable devices to create a virtual prototyping environment, where 3D models of components are superimposed, allowing for dynamic validation, real-time feedback, and gesture recognition to guide the assembly process, ensuring correct sequence and ergonomic alignment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If static visual aids and manual validation are used for assembly, then the assembly process can be performed with simple tools and procedures, but the ability to validate assembly sequence and clearance dynamically is insufficient
Solution Approach 1:
The patent creates a virtual copy of the physical assembly environment using 3D models of components and the workspace. This virtual prototype allows dynamic validation of assembly sequences and clearance without requiring complex physical measurement tools or procedures. The virtual model can be manipulated and validated computationally, improving reliability while avoiding the complexity of enhanced physical measurement systems.
Solution Approach 2:
The patent replaces manual physical validation with computational validation. Instead of relying on operators to physically check clearance and assembly sequence, the system uses computer algorithms to simulate and validate the assembly process. This substitution of mechanical/manual validation with computational methods improves accuracy without proportionally increasing physical system complexity.
2Productivity
If manual validation is performed for assembly, then the assembly process remains flexible and adaptable, but the time required for validation and the potential for human error increase
Solution Approach 1:
The virtual prototype system performs self-validation of the assembly sequence and clearance automatically. The system independently checks whether components can be assembled in the proposed sequence and whether sufficient clearance exists, without requiring operator intervention for validation. This automated self-service validation dramatically reduces validation time and eliminates human error while maintaining flexibility in assembly procedures.
Solution Approach 2:
The system provides immediate feedback on assembly validity by automatically checking the proposed sequence and clearance conditions. When an assembly step is invalid or clearance is insufficient, the system immediately identifies and reports the issue, allowing for rapid correction. This feedback mechanism accelerates the assembly process by eliminating time-consuming manual checking and reducing rework.
3Manufacturing precision
If clear validation of assembly sequence is provided, then the correctness of assembly can be ensured, but the complexity of tracking and validating each component increases
Solution Approach 1:
The patent uses a virtual 3D copy of all components and their spatial relationships to track and validate assembly. Instead of complex physical tracking systems, the system maintains digital twins of components that can be automatically tracked through the assembly sequence. This virtual tracking approach ensures precise component placement validation while avoiding the complexity of physical tracking infrastructure.
Solution Approach 2:
The virtual prototype system serves multiple functions simultaneously: it visualizes the assembly sequence, validates clearance, tracks component positions, and identifies potential conflicts. This multi-functional approach consolidates what would otherwise require multiple separate tracking and validation systems into a single integrated platform, improving precision without proportionally increasing complexity.

AI summary
In virtual prototyping and assembly validation, visual images of physical components of a product are captured through a camera inbuilt in an augmented reality/virtual reality (AR/VR) wearable device, registered as 3D models in a virtual workbench. When a first voice command is received to initiate recording, continuous visual motion signals are received as trajectories corresponding to assembling a 3D model of a component. They are recorded as an installation view of the component. The 3D model of the component is dynamically validated while assembling the virtual workbench. The installation view of the component and an installation view of a next component is stored as an animation assembly file. The animation assembly file may be extracted from the AR/VR application and stored in a visual enterprise application as a visual enterprise format such as visual design stream.
