Virtual Factory Layout Simulation for Ergonomic and Flow Analysis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for optimizing manufacturing facility layouts and flows require extensive, costly meetings involving multiple stakeholders, as they involve iterative design and coordination to address issues like ergonomics and tooling, which can be inefficient and time-consuming.
Innovation Solution
A computer system generates a simulated three-dimensional virtual environment of a manufacturing facility, allowing stakeholders to evaluate and modify layouts and flows remotely, using three-dimensional models of objects and input data sets to perform event, geometric, and ergonomic analyses, thereby facilitating remote and asynchronous planning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional iterative design meetings are used to optimize facility layouts, then comprehensive stakeholder input is obtained, but the process becomes time-consuming and costly
Solution Approach 1:
The patent creates a digital twin or virtual model of the manufacturing facility that replicates the physical environment. Stakeholders can review and provide feedback on this digital copy remotely, eliminating the need for physical meetings while maintaining comprehensive input gathering. The virtual model allows iterative design exploration without time constraints of scheduling in-person sessions.
Solution Approach 2:
The system introduces a computer system with simulation software as an intermediary between stakeholders and the facility design. This intermediary automatically processes stakeholder inputs, performs collision detection, and generates simulation results, replacing the traditional role of facilitators and reducing coordination overhead while maintaining comprehensive stakeholder engagement.
2Reliability
If multiple stakeholders coordinate iteratively to address ergonomics and tooling issues, then comprehensive design review is achieved, but the coordination complexity increases
Solution Approach 1:
The patent merges multiple analysis functions (collision detection, ergonomic analysis, tooling verification) into a single integrated simulation environment. Stakeholders interact with one unified system rather than coordinating multiple separate review processes, reducing coordination complexity while maintaining comprehensive design review across all critical aspects.
Solution Approach 2:
The simulation system performs multiple functions simultaneously - it can analyze collisions, ergonomics, tooling accessibility, and workflow efficiency within a single virtual model. This multi-functional approach allows diverse stakeholder concerns to be addressed through one platform, eliminating the need for separate specialized reviews and reducing overall coordination complexity.
3Ease of operation
If physical meetings are held for layout evaluation, then real-time stakeholder interaction is enabled, but travel and meeting costs increase
Solution Approach 1:
The patent replaces the mechanical system of physical travel and in-person meetings with an electronic/digital system. Stakeholders interact with the facility model through computer interfaces, allowing real-time collaboration without physical movement. The simulation software provides interactive capabilities that replicate and enhance traditional meeting functions while eliminating travel requirements.
4Measurement precision
If detailed ergonomic analysis is performed manually during meetings, then ergonomic issues are identified, but the analysis process becomes time-consuming
Solution Approach 1:
The simulation system performs ergonomic analysis automatically without requiring manual expert review. The software contains built-in ergonomic assessment algorithms that automatically evaluate the virtual facility model, identify potential issues, and provide recommendations. This self-service capability maintains high assessment accuracy while dramatically reducing the time required compared to manual analysis during meetings.
Solution Approach 2:
The ergonomic analysis is performed continuously as part of the simulation process rather than as a separate discrete activity. The system automatically updates ergonomic assessments whenever the facility model changes, providing continuous feedback without requiring repeated manual analyses. This continuous automation maintains precision while improving analysis speed and productivity.
Data Source
AI summary
Method, system, and computer program product for simulating the layout and flow of a manufacturing facility. An initial facility layout concept and a baseline input data set are received which define placement and movement of virtual objects within a virtual facility model. At least one of several analyses is performed based on the initial facility layout concept and the baseline input data set. An event flow analysis that outputs timing for movement of the objects from the initial positions may be performed. A geometric flow analysis that outputs interactions between the objects resulting from the movements from the initial positions may be performed. An ergonomic analysis that outputs human postures and motions resulting from interactions with objects may be performed. A simulated flow model for the manufacturing facility is generated. A three-dimensional virtual environment of the simulated flow model is generated and output for display.
