Latest Patents

Shirai's latest patents include a "System and method for product designing" and a "Power train supporting apparatus." The product design CAD data reconstruction unit is designed to reconstruct product design CAD data used for product evaluation. This process ensures that the data fulfills restrictive conditions obtained from the product evaluation based on the product structure for the initial design. The reconstructed product design CAD data is stored in a product design CAD data database. Upon receiving a corrected design, the product design CAD data for the initial design is read from the database and corrected along the design surface of the corrected design. The power train supporting apparatus features a ladder-like sub-frame located under the power train in a vehicle's engine compartment. This apparatus includes right and left sub-side members with curved portions that facilitate bending. The design allows for the weight of the power train to be supported by multiple engine mounts, which release the power train during a collision, preventing interference with the sub-side members.
