Solution Overview
Problem
Designing proper flow channels in three-dimensional CAD structures is labor-intensive and time-consuming, requiring repeated trial-and-error iterations due to the complexity of creating three-dimensional representations compared to two-dimensional drawings.
Innovation Solution
A design support system that includes a controlling unit connected to an input unit, which simulates a flow channel network by using flow channel width and depth to generate three-dimensional design data, allowing for efficient creation of both two-dimensional drawings and three-dimensional CAD models of flow channels.

1Manufacturing precision
If three-dimensional CAD is used to design flow channels, then the design quality and accuracy are improved, but the workload and time required increase significantly
Solution Approach 1:
The system creates a two-dimensional flow channel network as a simplified copy or representation of the three-dimensional flow channel structure. This 2D network captures the essential topology and geometry information, allowing designers to work with a less complex representation that can be automatically converted to 3D CAD models, thereby reducing design time while maintaining accuracy
Solution Approach 2:
The system transitions from two-dimensional flow channel network representation to three-dimensional CAD model generation. By establishing a mapping relationship between 2D network elements and 3D geometric features, the system enables automatic dimensionality conversion, allowing designers to benefit from simplified 2D design processes while obtaining accurate 3D models for manufacturing
2Manufacturing precision
If three-dimensional CAD is used to design flow channels, then the design quality and accuracy are improved, but the complexity of the design process increases
Solution Approach 1:
The design process is segmented into distinct stages: two-dimensional flow channel network design, network validation, and automatic three-dimensional CAD model generation. By dividing the complex 3D design task into manageable segments, the system reduces overall process complexity while maintaining high design accuracy through systematic progression through each stage
Solution Approach 2:
The two-dimensional flow channel network serves as an intermediary representation between the designer's conceptual input and the final three-dimensional CAD model. This intermediate 2D network structure simplifies the design process by providing a manageable intermediate form that can be automatically transformed into the final 3D model, reducing the complexity of direct 3D design operations

AI summary
A design support system (20) includes a controlling unit connected to an input unit. The controlling unit (21) obtains, from the input unit, information representing a flow channel network that simulates a flow channel shape. The controlling unit (21) then uses a flow channel width and a flow channel depth of the flow channel network, thereby generating design data of a three-dimensional flow channel that is obtained by three-dimensionalizing the flow channel network.
