Solution Overview
Problem
Existing robot simulation methods require operators to manually determine operation contents and motion velocities for human intervention-type robot systems, making the simulation process labor-intensive and inefficient, especially when optimizing cycle time without changing the motion program.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual determination of operation contents and motion velocities is used, then simulation accuracy is improved, but operator effort and time consumption increase
Solution Approach 1:
The simulation device automatically determines operation contents and motion velocities by itself without requiring manual operator input. The operation distributing part autonomously allocates operations to robot and human based on article weight, conveying distance, and required time, while the program generating part automatically creates motion programs, enabling the system to serve itself and eliminate manual determination steps
Solution Approach 2:
The patent replaces the manual mechanical process of determining operation contents and motion velocities with an automated computational system. The operation distributing part and program generating part use algorithms to calculate and assign operations, substituting the manual mechanical approach with an automated information processing system that reduces operator effort while maintaining simulation accuracy
2Productivity
If cycle time optimization is achieved by changing positions of robot and human, then productivity is improved, but motion program complexity increases
Solution Approach 1:
The patent makes the motion program dynamic and adaptable rather than static. The program generating part automatically adjusts motion programs based on the distributed operations, allowing the system to optimize cycle time through flexible program generation rather than complex fixed-position configurations. The motion programs can be dynamically modified to reflect operation distribution results, reducing the need for complex predetermined position arrangements
3Ease of operation
If automatic operation distribution is implemented, then ease of operation is improved, but calculation complexity increases
Solution Approach 1:
The patent segments the complex simulation process into distinct functional modules: the operation distributing part that allocates operations based on article weight, conveying distance, and required time; the program generating part that creates motion programs; and the cycle time calculating part that computes simulation results. This segmentation hides the underlying calculation complexity within specialized modules while presenting a simple interface to the operator
Solution Approach 2:
The operation distributing part acts as an intermediary that simplifies the interface between the operator and the complex calculation system. It automatically translates operational requirements into distributed task assignments, mediating between the simple input of simulation parameters and the complex internal calculations of operation allocation and cycle time computation
