Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing simulation systems are limited in evaluating the behavior of manufacturing devices and overall manufacturing systems before the design is complete, and they are primarily designed for machine tools, making them unsuitable for evaluating machine design appropriateness.
Innovation Solution
A simulation system comprising a control device for executing sequence and motion control of a control object and an information processing device for data exchange, visualization, and analysis, allowing for the presentation of the control object's behavior and design data to evaluate the manufacturing device and system behavior effectively.

Engineering Contradiction Analysis
1Reliability
If an interference checker is used to evaluate processing program appropriateness after machine tool design, then collision prevention is improved, but the ability to evaluate machine design appropriateness deteriorates
Solution Approach 1:
The simulation system is designed to perform multiple evaluation functions: it can evaluate both processing programs and machine designs. The system uses a standard simulation interface that accepts various types of evaluation targets (machine tools, manufacturing systems, etc.) and evaluation criteria (collision detection, cycle time optimization, design appropriateness), making it universally applicable across different evaluation needs rather than limited to a single function.
Solution Approach 2:
The system dynamically adapts its simulation capabilities based on the evaluation target. It can switch between evaluating existing machine tools with complete designs and evaluating design concepts before finalization. The simulation model can be configured to represent different stages of design completeness, allowing flexible evaluation at various development phases.
2Measurement precision
If simulation is limited to machine tools with complete designs, then processing program verification is improved, but overall manufacturing system evaluation deteriorates
Solution Approach 1:
The simulation system divides the manufacturing system into separable components (machine tools, workpieces, fixtures, manufacturing systems) that can be simulated independently or in combination. This segmentation allows the system to evaluate individual machine tools with high precision while also enabling integration into broader manufacturing system evaluations, accommodating both detailed program verification and overall system assessment.
Solution Approach 2:
The system introduces a standardized simulation interface as an intermediary between the evaluation target and the analysis functions. This interface layer enables seamless integration of diverse evaluation targets (from simple machine tools to complex manufacturing systems) while maintaining consistent evaluation methods, thus expanding system evaluation scope without compromising verification accuracy.
3Ease of manufacture
If evaluation is performed only after machine design is complete, then design finalization is improved, but design optimization opportunities deteriorate
Solution Approach 1:
The simulation system enables preliminary evaluation of design concepts before the machine tool design is finalized. By accepting design data in various completeness states and providing early feedback on design appropriateness, the system allows designers to optimize designs during the development phase rather than waiting until completion, thereby reducing redesign time and accelerating the overall development process.

AI summary
A simulation system includes a control device for controlling a control object; and an information processing device configured to exchange data with the control device. The control device includes a computation unit configured to execute sequence control and motion control of the control object; and an output unit configured to output a fixed interval of data related to the sequence control and the motion control of the object. The information processing device includes a storage module configured to store design data representing at least a portion of the configuration of the control object; and a visualization module configured to present a visual representation of the behavior of the control object around a period in time that satisfies a predetermined criteria using the fixed interval of data output from the control device, and the design data, where the fixed interval of data from the control device the visualization module uses is the fixed interval of data over a predetermined period that includes the period in time.
