Mixed Reality Installation Testing for Component Collision Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for testing the installation or removal of components, whether through hardware models or virtual reality, face challenges such as high costs, long lead times, and the inability to accurately simulate physical properties like friction and weight, making it difficult to assess the buildability of systems effectively.
Innovation Solution
A method and device utilizing a mixed reality system that combines real and virtual elements, allowing for the surveying, tracking, and visualization of components and installer interactions within an installation environment, which includes the use of augmented reality to simulate physical properties and provide feedback, enabling realistic and cost-effective testing of installation or removal processes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If hardware models with 3D-printed components are used for testing installation processes, then the buildability can be realistically tested and evaluated, but high costs arise for component procurement and installation, and long lead times are needed
Solution Approach 1:
The patent creates a virtual copy of the installation environment and components using mixed reality technology. Instead of physically printing and procuring components for testing, the system generates a virtual representation that can be immediately accessed and tested, eliminating the lead time associated with physical manufacturing while maintaining realistic testing capabilities through accurate virtual modeling of installation processes
2Reliability
If hardware models are used for testing, then installation processes can be evaluated, but high costs arise for component procurement and installation
Solution Approach 1:
The system creates a virtual copy of the installation environment, replacing the need for physical components. The mixed reality system generates a digital twin of the installation scene, allowing multiple testing iterations without the cost of procuring and disposing of physical components, while still enabling comprehensive evaluation of installation processes
Solution Approach 2:
The patent changes the state of the installation environment from physical to virtual. By transforming the hardware model into a mixed reality environment where virtual and real elements coexist, the system enables testing without physical component consumption, reducing costs while maintaining evaluation reliability through accurate virtual representation of physical properties
3Productivity
If virtual reality applications are used to check buildability, then experiments can be reconstructed cost-effectively and quickly, but force expenditures, weights, and friction sensation cannot be virtually mapped
Solution Approach 1:
The patent merges virtual and real elements in a mixed reality environment. Instead of using pure virtual reality that lacks physical feedback, the system combines virtual models with real physical components and sensors, allowing the system to both quickly reconstruct experiments and accurately measure physical properties like force, weight, and friction through integrated sensing of real-world interactions
4Reliability
If area models are used for testing, then processes can be realistically tested, but the hardware version mapped after printing or procurement possibly no longer reflects the current status
Solution Approach 1:
The patent implements a dynamic virtual model that can be continuously updated. The mixed reality system maintains a live connection to the installation environment, allowing the virtual representation to be dynamically updated to reflect current hardware versions, component changes, or process modifications, ensuring the model always accurately represents the current state without requiring physical retooling
Data Source
AI summary
A method, computer program, and device for testing the installation or removal of at least one component within an installation environment, comprising real and virtual elements. A component, installation environment, installer's hand, and a mixed reality system worn by the installer may be calibrated. During an installation or removal attempt, the component, installer's hand, and mixed reality system are tracked. Collisions or near-collisions between the component, installer's hand, tool, and the real and virtual elements, as well as among components, are detected. Obstructions are identified. The installation or removal attempt is visualized via the mixed reality system. Additionally, the installation or removal path and information on collisions or near-collisions are displayed.
