Check the test instrument, connect the PCB board, set the test parameters, and record the analysis results...... In the new energy laboratory of Qingdao Dingxin Communication Co., Ltd. (hereinafter referred to as "Dingxin Communication"), Wang Zhe, a fourth-year student majoring in communication engineering at the School of Ocean and Spatial Information of China University of Petroleum (East China), is carrying out the testing and functional verification of the intelligent and friendly photovoltaic inverter project under the guidance of Yang Chao, a senior engineer of Dingxin. According to the school-enterprise joint graduation project plan, he will complete his graduation project in Dingxin Communication. For the graduates of Shihai University of Aerospace, the practice of taking the problems and needs in enterprise R&D and production as the topic of graduation design like Wang Zhe has gradually become the norm.
For a long time, there have been problems such as emphasizing research over practice, theory over application, etc. China University of Petroleum (East China), Qingdao University, Qingdao University of Technology, Qingdao Binhai University and other universities in Qingdao have joined forces to explore and implement the school-enterprise collaborative education model of "enterprises ask questions and students answer questions", guide graduates to solve practical problems in their graduation projects, improve graduates' ability to link theory with practice and hands-on practice, and make the "last pass" of talent training quality.
Students' graduation projects are derived from the needs of enterprises
Sun Haoran, a senior student majoring in mechanical manufacturing and automation at the School of Mechanical and Automotive Engineering of Qingdao University of Technology, is making final optimization of the robot program in order to be launched and applied to production as soon as possible. The topic of his graduation project is "Offline Programming and Optimization of Robot Welding in the Middle Section of 30-ton Digging Boom", and the main design content is offline programming. "This topic was proposed by Weichai according to its own needs, and after we selected the topic according to our own advantages, school tutors and enterprise mentors will give us guidance. On the second day of the spring semester this year, I went to the graduate school to start my graduation project, which is now almost finished. Sun Haoran told reporters. After this design is put into use, the working attitude and running path of the welding robot can be optimized, saving running time and improving production efficiency.
On April 23, Shen Zhen, a senior student majoring in artificial intelligence at the School of Information Engineering of Qingdao Binhai University, completed his graduation defense. The title of his graduation project is "Design and Application of Rodent-proof Plate Placement Behavior Detection Algorithm in Home Appliance Industry Based on Deep Learning". "Refrigerators and other electrical appliances are placed in actual production, but they may be missed during manual operation. This work relies on manual inspections to be time-consuming and labor-intensive, and not always effective. My graduation project was to develop an intelligent system to replace manual inspection and improve the accuracy of rodent-proof board placement detection. In July last year, Shen Zhen started this work when he interned at Qingdao Zhongdao Chenyuan Intelligent Technology Co., Ltd.
"The graduation project is a bridge for students to apply the theoretical knowledge they have learned to practical engineering projects, and the direction of the topic must meet the actual needs of engineering practice, so as to help cultivate students' engineering thinking. Li Shibao, deputy dean of the School of Ocean and Spatial Information of China University of Petroleum (East China), said when talking about the original intention of introducing enterprise topics. This year, there are more than 300 graduates of the college's electronic information and space engineering, of which 70% of the graduation design topics are from Hisense, Goertek, Dingxin and other enterprises. Students can also make full use of the company's laboratory resources to improve the quality and effect of their graduation project.
According to Wang Dechang, deputy dean of the School of Mechanical and Electrical Engineering of Qingdao University, they explored and tried the undergraduate graduation design model of "enterprises solve questions and students answer questions" in 2020. This year, there are more than 240 graduates of mechanical engineering, energy and power engineering in the college, of which more than 1/4 of the graduation design topics come from well-known enterprises such as Hisense and Qingte. In addition, some of the students' graduation projects are selected from cross-cutting topics in schools and companies. More than 50 graduates from the School of Mechanical and Automotive Engineering of Qingdao University of Technology majored in mechanical design, manufacturing and automation, vehicle engineering, intelligent manufacturing engineering and other majors have selected their graduation design topics from Weichai Group and Halma Group. Graduates do their graduation projects in the front line of the enterprise, and the relevant results will also be applied to the actual production of the enterprise. As a result, some outstanding graduates have signed contracts to work in cooperative enterprises.
"Dual mentors" guide to ensure that the completion of the design can be applied
The development of spectral recognition of fruit and vegetable freshness algorithm, the antenna design applied to wearable products, the optimization design of permanent magnet synchronous motor for electric drive axle of new energy commercial vehicles, the load adjustment and matching research of hot gas defrosting system, and the design of automatic antifreeze recovery device for test run...... The topics of the enterprise are not only close to the actual production, but also at the forefront of the industry.
The reporter learned that every question from the enterprise has been considered, which must not only meet the needs of industrial development and the actual needs of the enterprise, but also meet the requirements of the training program and the personal characteristics of students. Each school has set up a multi-subject topic selection design team such as professional teachers and external enterprise engineers to ensure that the topic selection meets the requirements of the training program, fully helps students to devote themselves to practical training and do a good job in the last answer sheet before graduation.
Universities such as China Stone University, Qingdao University, Qingdao University of Science and Technology have established a "dual tutor system" to better help students do a good job in graduation projects. During the graduation project, the tutor provides academic guidance to help students clarify the research direction, design methods and theoretical framework, and ensure that the graduation project meets the academic requirements and discipline standards. Corporate mentors provide students with hands-on guidance to help them understand the actual needs of the industry, technology trends, and workflows. "In order to improve my engineering literacy and better guide students' graduation theses, I have had many exchanges with enterprise engineers to understand the relevant engineering technologies and requirements on the spot. Gu Chaozhi, the person in charge of the graduation project of the Department of Communication Engineering of the School of Ocean and Spatial Information of Zhongshi University and the instructor of the school, said. In the past three years, the college has hired engineers and scientific researchers from enterprises and scientific research institutes as student instructors, and more than 70% of the students have been equipped with "double tutors", that is, 1 on-campus instructor + 1 tutor with engineering practical experience in off-campus enterprises or other scientific research institutes.
"Enterprise tutors can start from the actual work, guide students to comprehensively consider the feasibility of solving problems and the advantages and disadvantages of the program, and guide students to comprehensively consider the impact of technical solutions on society, health, safety, law, environmental protection and sustainable development, etc., and strengthen the training of non-technical factors for students in the training program. Lei Chao, director of the RF department of Goertek Acoustics Co., Ltd., is the "corporate mentor", and he believes that the real engineering environment can help students get greater gains from their graduation projects.
Enterprises, schools, and students collaborate to achieve a win-win situation for all parties
"When I was doing my graduation project at CTI Navigation, my engineering practice ability was greatly improved, and it also gave me a certain understanding of the management mode and technical direction of CTI Navigation. Yao Jiahua, an undergraduate student of Zhongshi University, received an additional "surprise" when he was doing his graduation project, which allowed him to reach an employment contract intention with the company.
Shen Zhenshan, who is currently studying at Jiangnan University, is a graduate of Qingdao University's School of Mechanical and Electrical Engineering. In 2023, the children's balance bike scheme he designed when he was doing his undergraduate graduation project has been adopted by Qingdao Shangnuo Baby Products Co., Ltd. The balance bike adopts a modular design, which can meet the needs of children aged 0-6 years old, and at the same time adds situational elements to enrich the fun of children when using the balance bike. "Now when I design products for horizontal projects, I will not only consider how to design them, but also how to reduce costs and how to really implement them, which are all gains when I am doing undergraduate graduation design. In Shen Zhenshan's view, the biggest gain of doing graduation design based on the actual needs of enterprises is to cultivate engineering design thinking.
The form of "real questions and real work" can achieve a win-win situation for all parties. According to Peng Zilong, deputy dean of the School of Mechanical and Automotive Engineering of Qingdao University of Technology and executive vice president of Qingdao Institute of Technology-Weichai Modern Industry College, students can strengthen the ability to link theory with practice when answering "enterprise questions", so as to better adapt to the needs of enterprises, and some students' achievements have even won awards in national competitions; In the process of course guidance, improve the quality of student training; for enterprises, it can not only solve some practical problems, but also tap and recruit talents that are more in line with corporate values and enterprise development needs in the process of guiding students, enhance the effectiveness of talent recruitment, and avoid waste of resources.
