If your SCI paper lacks innovation, here are some suggestions that may be helpful:

1. Rethink the research problem: you can re-examine the problems discussed in the paper and try to find new problems, new methods and new perspectives to explore innovation.

2. Explore new research fields: You can try to enter new research fields and explore new research problems and solutions in this field.

3. Pay attention to future research: We can try to explore the current or future scientific and technological trends and cutting-edge technologies, and explore how to apply them to papers to effectively enhance the scientific research value and innovation.

4. Mining data analysis: You can analyze new conclusions, trends or laws from existing data and try to extract innovative insights.

5. Change research methods: You can explore new research methods, algorithms or models in order to propose new solutions based on the original research problems.

In short, if your SCI paper lacks innovation, you need to think about how to break through the existing limitations. It is important that you keep an open mind and actively seek new research perspectives and methods. At the same time, you can also consult teachers and colleagues, listen to their suggestions and opinions, and strive to pursue the innovation and scientific research value of the paper.
