Solution Overview
Problem
Existing additive manufacturing methods face challenges in reducing the number of manufacturing paths without limiting the types of paths that can be generated, especially as the complexity of the manufactured object increases, leading to inefficiencies in productivity and manufacturing accuracy.
Innovation Solution
A control information generating device and method that reduces the number of manufacturing paths by connecting adjacent paths at specified connection positions, using a manufacturing information acquisition unit, connection position specifying unit, and path connection unit to form a bead layer, ensuring minimal deviation from the original paths.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the number of manufacturing paths is increased to cover complex shapes, then the coverage of the manufactured shape is improved, but the number of start parts and end parts increases, leading to more frequent stopping and reduced productivity
Solution Approach 1:
The patent merges multiple manufacturing paths by connecting them at specified positions to form continuous paths. This reduces the total number of separate paths, thereby decreasing the number of start and end points where stopping and resuming occurs, thus improving productivity while maintaining shape coverage
2Productivity
If the number of manufacturing paths is reduced to improve productivity, then the number of start parts and end parts is reduced, but the ability to accurately form complex shapes is limited
Solution Approach 1:
The patent strategically merges adjacent manufacturing paths at carefully selected connection positions where the geometric continuity is maintained. This allows reduction in path count while preserving the ability to accurately form complex shapes by ensuring that merged paths still follow the required geometry
3Productivity
If manufacturing paths are significantly changed to reduce path count, then productivity is improved, but the deviation from original paths increases, affecting manufacturing accuracy
Solution Approach 1:
The patent applies local modification by making changes only at specific connection positions between adjacent paths rather than globally altering all paths. The connection positions are selected where minimal deviation is required, thus maintaining manufacturing accuracy while achieving path reduction for improved productivity

AI summary
A control information generating device includes: a manufacturing information acquisition unit configured to acquire information on manufacturing paths; a connection position specifying unit configured to specify, from the acquired information on the manufacturing paths, connection positions at which a pair of manufacturing paths arranged adjacent to each other and having continuous formation order are connected to each other; a path connection unit configured to newly add a connection path that connects the pair of manufacturing paths to each other at the connection positions, and connect the pair of manufacturing paths to each other; and a control information output unit configured to repeat connection between the manufacturing paths until the number of the manufacturing paths becomes equal to or less than a predetermined upper limit, and output the information on the connected manufacturing paths as the control information.
