  • Patent number: 10761519
    Abstract: A product design and process design device includes: a storage unit that stores design specification information containing the tolerance of a dimensional variation at any site of an assembly product, part dimension error information, assembly facility error information, assembly tolerance information, the part dimension error information, and the assembly facility error information, part manufacturing cost information, and facility investment cost information with respect to the assembly facility error information; a tolerance distribution processing unit that uses the assembly tolerance information to generate proposed tolerance distributions that differ in distributional combination with respect to each error, and calculates part manufacturing costs and facility investment costs; a facility planning processing unit that determines a proposed tolerance distribution, with, as an evaluation index, total production costs respectively including the sums of the part manufacturing costs and the facility investmen
    Type: Grant

  • Patent number: 10114910
    Abstract: In order to automatically determine a structural member that is included in a structure and has flat surfaces, an input unit is configured to input three-dimensional point group data of the structure, a flat surface extraction unit is configured to extract the flat surfaces of the structure based on the three-dimensional point group data, a grouping unit is configured to group the flat surfaces into flat surface groups based on an angle of each of the flat surfaces with respect to a reference direction and a distance between the flat surfaces, a connection relationship extraction unit is configured to extract a connection relationship between the grouped flat surface groups, and a determination unit is configured to determine the structural member that the structure is constructed from based on the extracted connection relationship.
