Solution Overview
Problem
Existing simulation technologies for conveyor systems fail to accurately simulate the operation of conveyor devices in a manner similar to actual operations, particularly in preventing interference between workpiece models in a virtual space.
Innovation Solution
A simulation device and method that includes a model arrangement section, offset setting section, conveying operation execution section, interference detection section, non-interfering position search section, and workpiece position correction section to arrange and correct workpiece models in a virtual space, preventing interference by setting offset amounts and searching for non-interfering positions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If workpiece models are arranged at reference positions on the conveyor device model without offset, then the simulation is simple and easy to implement, but interference between workpiece models cannot be prevented and the simulation does not reflect actual operations
Solution Approach 1:
The simulation device performs preliminary actions by detecting potential interference between workpiece models before the conveying operation executes. The interference detection section identifies overlapping positions in advance, allowing the system to prevent interference through preliminary position adjustment rather than reacting after interference occurs. This maintains simulation accuracy while managing complexity through proactive detection.
Solution Approach 2:
The simulation structure is made dynamic by allowing workpiece model positions to be adjusted during the simulation process. When interference is detected, the system dynamically modifies the positions of workpiece models to eliminate overlap. This dynamic adjustment capability enables the simulation to adapt to interference conditions while maintaining operational realism, resolving the contradiction between accuracy and structural complexity.
2Reliability
If offset amounts are set for all workpiece models to prevent interference, then interference between workpieces is prevented, but the simulation becomes more complex and time-consuming
Solution Approach 1:
Instead of applying offset adjustments to all workpiece models unconditionally, the simulation device applies partial action by only adjusting positions of workpiece models that are detected to be in interference. This selective approach prevents unnecessary computational overhead and time loss while still achieving complete interference prevention. The system performs exactly the amount of correction needed—no more, no less.
Solution Approach 2:
The simulation device implements self-service by automatically detecting interference and performing position corrections without requiring external intervention or manual adjustment. The interference detection section and position correction section work autonomously to identify and resolve interference issues, reducing the time and effort required compared to manual simulation management while maintaining reliable interference prevention.
3Reliability
If the simulation device detects and corrects interference in real-time during conveying, then the simulation reflects actual operations accurately, but the computational complexity and processing requirements increase
Solution Approach 1:
The control system is segmented into distinct functional sections: model arrangement section, interference detection section, and position correction section. Each section handles a specific aspect of the simulation process independently. This segmentation reduces control system complexity by dividing the overall function into manageable, specialized components that can be implemented and processed separately, while still achieving real-time interference detection and correction for realistic simulation.

AI summary
A simulation device that performs a convey operation simulation in which the position and orientation of a workpiece in the conveyor device changes in a random fashion. The simulation device may include a model arrangement section, an offset setting section for setting an offset amount from the reference position of the workpiece model, a conveying operation execution section for executing a convey operation to convey the workpiece model by the conveyor device model, an interference detection section for detecting interference between two workpiece models, a non-interfering position search section for searching for a non-interfering position where interference does not occur, and a workpiece position correction section for correcting the position of at least one workpiece model based on the non-interfering position.
