Secondly, the digital era has propelled the digitization transformation of mechanical design and manufacturing.The widespread use of digital tools such as Computer-Aided Design (CAD) and Computer-Aided Manufacturing (CAM) has made the design, simulation, and manufacturing processes of mechanical products more efficient and precise.This necessitates students in mechanical engineering to acquire skills that complement the use of these tools and collaborate in a digital environment.
Additionally, engineers in the digital era need the ability to handle big data and conduct data analysis.The vast amount of data generated during the operation of mechanical systems needs to be fully utilized to enhance system performance and predict maintenance needs.Therefore, education in mechanical engineering must align with the trends in data science and analysis, cultivating students with the capability to process and analyze large datasets.[1]

Issues and Challenges in Traditional Curriculum Systems
However, traditional curriculum systems in mechanical engineering face a series of problems and challenges in the digital era.Firstly, traditional systems often emphasize the imparting of foundational theories, while the importance of applied skills and practical experience is increasingly highlighted in the digital era.Students lack practical experience related to digitization in traditional systems, potentially leading to inadequate preparation for real-world work.
Secondly, some traditional courses have not been updated in a timely manner and fail to cover emerging technologies and fields.For instance, there is a limited coverage of knowledge in digitized areas such as artificial intelligence and the Internet of Things, which may pose difficulties for graduates in applying new technologies in the workplace.
Moreover, traditional mechanical engineering courses tend to lean towards the teaching of a single discipline, lacking interdisciplinary integration.However, in the digital era, mechanical engineers need to possess knowledge in multiple fields, such as cross-disciplinary knowledge with electronics engineering and computer science.Therefore, traditional curriculum systems need to undergo interdisciplinary integration to cultivate more well-rounded mechanical engineers.

Development Trends in Vocational Education for Mechanical Engineering
To address the challenges of the digital era, vocational education in mechanical engineering is evolving towards a more application-oriented and practical direction.Firstly, new curriculum systems focus on cultivating students' practical operational skills, integrating the use of digital tools into actual engineering projects.Through project-based learning, students can apply their acquired knowledge in real-world scenarios, enhancing their practical experience.[2] Secondly, there is an acceleration in the frequency of curriculum system updates, closely tracking the development of digital technology.The introduction of the latest digital tools and technologies allows students to engage with the latest industry trends during their learning process, enhancing their adaptability to the demands of the digital era.
Additionally, vocational education in mechanical engineering is moving towards interdisciplinary integration, organically combining knowledge related to digitization with other fields.By incorporating cross-disciplinary fusion with electronics engineering, computer science, and other disciplines, students can gain a more comprehensive understanding and solve complex engineering problems.
In summary, the digital era presents both new opportunities and challenges for vocational education in mechanical engineering.A thorough analysis of the impact of the digital era on mechanical engineering, the issues and challenges in traditional curriculum systems, and the trends in vocational education helps in better formulating and adjusting curriculum systems to cultivate highly qualified engineers adapted to the demands of the digital era.[3][4]
