Pay attention to these 7 points to avoid design mistakes

As a mechanical design engineer, it is difficult to avoid design mistakes in daily work. Every excellent mechanical design engineer gradually grows up from various failures, which means that mistakes are inevitable for a mechanical designer. .

So how to avoid mistakes in the process of mechanical design work, the following points are worth paying attention to:

Pay Attention To These 7 Points To Avoid Design Mistakes

Design mistakes are the most common mistakes that designers make in web design. They can be easily avoided by just paying attention to these 7 points.

– Design is a process.

– Understand your customer.

– Make sure your design is functional and usable.

– Keep it simple and clean.

– Avoid skeuomorphism or anything that looks out of place on the screen.

– Don’t use too much text on one page, keep it short and concise for better readability.

– Make sure your fonts are readable and legible, avoid using too many fonts together or with a lot of contrast between them

1. The key points of the parts drawing should be highlighted

The processing benchmarks and processing methods are clear at a glance; there should be a lot of tolerances, and no unnecessary tolerances are marked;

For parts with complex structure, if the 3 views are not clearly expressed, add views, section views, partial enlarged views, and use the partial views that should be used.

Of course, it is very important. Before taking out the part drawing for processing, be sure to change the color of each view and put it in the assembly drawing for comparison to see if there is any inconsistency with the assembly drawing.

Finally, be sure to print it out to see if the material, surface treatment, heat treatment, quantity, and name are correct, and if there is any leaking size or something. An indicator to check the quality of your part drawings is the number of times the processing department or manufacturer asks for drawings. If you often receive calls or emails from the processing department and the manufacturer to consult the content of the drawings, sorry, the quality of your drawings needs to be improved;

2. The assembly drawing must keep improving

A line is drawn crooked, the line type is selected wrong, the layers are used wrong, the three views do not match, the individual parts only have one view, the size of some parts is not marked, the font size does not meet the requirements, the key structure lines are piled up in several layers and cannot be distinguished Which is which, etc., designers encounter such problems every day. If you don’t think the above questions are important, then you must be a wrong designer. A good designer will not let go of any of the above details, and must not be stingy with the assembly drawings.

3. For large quantities of parts, try to make samples to confirm

The quantity of some parts is very large, and a set must be tried for the first design. Please ask the relevant personnel of engineering and assembly to see if there is any modification, and then officially make it after modification.

4. Go to the assembly site often and ask the assembly staff about the problems in the assembly process.

In some places, the wrench cannot be pulled down, in some places it sticks out unsightly, in some places it is very laborious to adjust, in some places disassembly requires major surgery, in some places there is no benchmark, in some places the position cannot be found after it is removed, and It takes a lot of time to adjust and so on, and these issues need to be taken seriously. Work on the solution with the assembler, reflect on the drawing, and jot it down in a notebook for next time.

5. Customer requirements must be confirmed and confirmed again.

If the customer’s request is not taken seriously, it will definitely suffer a big loss.

Equipment size, weight, process flow, frame structure type, technical details of important parts, quality requirements of products. For example, if some equipment is to be exported to other countries, whether there are regulations on voltage, air pressure, sensor type, models and manufacturers of various standard devices, whether there are special acceptance standards, and whether there are special requirements for safe styles, etc. These must be carefully confirmed and taken seriously.

6. Pay attention to the calculation manual

The calculation specification is an inspection process. If you can completely reproduce the entire design calculation process in the calculation manual, then the mistakes in the previous design will be visible at a glance.

7. Refer to excellent design

Some companies may not have so many resources to use, then search the Internet for similar articles or posts, ask experienced designers if they have encountered similar structures, and collect more information for their own use.

If the designer makes something that is pleasing to the eye and comfortable, and there is no better solution to replace the existing solution, then it is a success.
