Engineering Contradiction Analysis
1Manufacturing precision
If symmetric models are manually constructed in virtual space, then model accuracy can be ensured, but construction time and complexity increase significantly
Solution Approach 1:
The patent applies the copying principle by automatically generating symmetric component models through replication of the original component model across a reference plane. Instead of manually constructing each symmetric model, the system creates accurate copies by reflecting the original model's geometry, parameters, and operational characteristics, thereby maintaining high construction accuracy while dramatically reducing the time required for model creation.
2Reliability
If multiple component models are arranged in virtual space, then simulation comprehensiveness improves, but system complexity increases
Solution Approach 1:
The patent applies the universality principle by creating symmetric component models that can be used in multiple simulation scenarios. The symmetric models share the same operational parameters, control logic, and functional characteristics as the original models, allowing the system to handle multiple components with unified management rather than requiring separate complex configurations for each component type.
3Reliability
If virtual operation parameters are replicated for symmetric models, then simulation consistency improves, but processing load increases
Solution Approach 1:
The patent applies the copying principle to virtual operation parameters by replicating the operational characteristics, control parameters, and functional behaviors from the original component model to its symmetric counterpart. This ensures that both models respond consistently to the same control inputs and environmental conditions, maintaining simulation reliability while using efficient parameter replication rather than independent parameter definition.

AI summary
A simulation device capable of easily constructing the layout of a three-dimensional model of a robot system in a virtual space. The simulation device includes a model arranging section that arranges a component model in a virtual space, the component model being a three-dimensional model of a component of the robot system; a reference setting section that sets a reference point, a reference axis, or a reference plane in the virtual space; a symmetric model generation section that generates a symmetric component model of the component model arranged in the virtual space, the symmetric component model being a three-dimensional model symmetric with respect to the reference point, the reference axis, or the reference plane; and a simulation section that executes a simulation to simulatively operate the component model and the symmetric component model in the virtual space.
