The article discusses how using computer-aided design in mechanical systems can improve product design, reduce costs, and increase efficiency. The researchers focused on developing a web-based innovation design system for automobile cover molds. By combining genetic algorithms with computer-aided design, they were able to significantly reduce both time and cost compared to traditional methods. The new system showed a 93% working efficiency, outperforming the traditional method's 70%. This approach can help companies save money and time in designing mechanical systems.
