Can mechanical analysis diagram be used for patent drawings?

Here's what I found:

The attached drawings are an integral part of the manual. The function of the appended drawings is to supplement the description of the text part of the specification with graphics, so that people can intuitively and vividly understand each technical feature and overall technical scheme of the utility model. Therefore, the attached drawings in the specification should clearly reflect the contents of the utility model.

according to the provisions of article 17, paragraph 5, and article 18 of the detailed rules for the implementation of the patent law, the appended drawings of the specification are examined. The examination of the attached drawings of the instruction manual includes the following contents:

(1) The drawings shall not use engineering blueprints or photographs.

(2) The attached drawings shall be drawn with drawing tools including computers and black ink, and the lines shall be uniform and clear, and shall not be colored or altered; There shall be no borders around the attached drawings that have nothing to do with the drawings.

(3) The attached drawings shall be numbered in Arabic numerals, represented by Figure 1 and Figure 2, and shall be marked directly below the corresponding drawings.

(4) The attached drawings should be drawn vertically on the drawings as far as possible, and clearly separated from each other. When the horizontal dimension of the part is obviously larger than the vertical dimension and must be arranged horizontally, the top of the drawing should be placed on the left side of the drawing. When there are more than two drawings on a page, and one of them has been horizontally arranged, the other drawings on the page should also be horizontally arranged.

(5) The size and clarity of the attached drawings shall ensure that all details in the drawings can still be clearly distinguished when the drawings are reduced to two thirds, so as to meet the requirements of copying and scanning.

(6) when an application for a patent has multiple drawings, in the drawings used to represent the same embodiment, the reference numerals indicating the same component (the same technical feature or the same object) should be consistent. The same reference numerals used in the specification and the drawings shall indicate the same components. The reference symbols not mentioned in the text of the instruction manual shall not appear in the attached drawings, and the reference symbols not appearing in the attached drawings shall not be mentioned in the text of the instruction manual.

(7) The attached drawings shall not contain other notes except the necessary words; Words should be in Chinese, and if necessary, the original text can be indicated in parentheses.

(8) The structural block diagram, logical block diagram and process flow diagram shall be provided with necessary words and symbols.

(9) The same drawing should be drawn at the same scale, and a partial enlarged drawing can be added to clearly show one of the components.

there should be drawings showing the shape, structure or combination of the product to be protected in the attached drawings of the specification, not only the drawings showing the prior art, but also the drawings showing the effect and performance of the product, such as temperature change curves.

The attached drawings of the instruction manual shall be numbered in Arabic numerals.

conclusion: mechanical analysis diagram can be used. It is also used to supplement the description of the text part of the manual, so that people can intuitively and vividly understand each technical feature and overall technical scheme of the utility model.
