Amendments to the claims shall be based on the description. The applicant may modify the preamble of the claim or modify the characteristic part to make it more accurately consistent with the content of the invention or more logical.

Modifications to the substantive parts of the description, that is, the purpose of the invention, technical solutions, effects and embodiments, are generally not allowed, but may be considered in very special circumstances. For example, if the purpose of the invention is obviously incompatible with the technical solution, the purpose of the invention can be appropriately modified based on the technical solution; if the application meets the requirements of unity, the description should be modified to make it comply with the requirements of unity; when applying, only write The content in the claims is added to the description, etc. Modifications to design pictures or photos are limited to outlining unclear lines, overlaying text that cannot be protected, or correcting obvious errors and inconsistencies in views.
