Qi Jiuyuan took the drawings aside, and then sorted them out carefully.

I have to say that the workload is really large, but fortunately, he has a deep foundation, and it can be seen at a glance whether these designs are reasonable or not.

To look at these drawings, we must first see whether the structure is reasonable, reasonable can be manufactured, and it is useless to continue to look at unreasonable.

But what made him extremely annoyed was that just by looking at it, he found a lot of problems, even if it was unreasonable, the previous more than ten copies were not painted in accordance with the requirements of the drawing, and some of the drawings were crooked like graffiti!

Unqualified, unqualified, unqualified, unqualified...... Still unqualified!!

He looked at it one by one, but none of them could be eyed!

He really couldn't think of how these people could design such a thing, and the standard was too low!

The next dozens of copies in a row, all of them are almost the same.

"Huh......" Finally, Qi Jiuyuan's eyes froze, and his hand rested on a neat and tidy design drawing.

Judging from the appearance alone, this design drawing is better than the previous one I don't know how many times, and it also draws the parts and structures of the mecha according to the requirements and proportions of the drawing, and it is not a big problem to sweep it at a glance, but when he takes a closer look, he finds that the structure of one place is a little different.

Whether the newly designed mecha can be used depends on whether it can be manufactured and successfully show its functions and uses.

So of course, it's not enough to just look at it, but generally speaking, as long as the structure inside conforms to the current mecha theory, then it can basically be done.

At the moment, this design diagram seems to be fine, but there is a structure that is different from the common light mecha structure now, and it is the first time he has seen this structure, and the structure and materials are different from those on the market.

"Replace AE644 alloy with AE583 alloy?" Qi Jiuyuan fell into deep thought.

At this time, Qin Ming was preparing for class, and when he came back to his senses, he found that Qi Jiuyuan was still tidying up on the side, so he turned his head to look at him, but he actually found that Qi Jiuyuan was actually holding a design and seemed to be pondering something.

Qin Ming was a little unexpected, wouldn't he, could someone really design a reasonable mecha?

He didn't have much hope, because only people with a lot of practical experience could design a mech and make it work for its intended use, and he didn't think there would be anyone like that among the students of that course.

"Jiuyuan, have you found anything, is there any qualified?" Qin Ming asked.

Qi Jiuyuan suddenly came back to his senses, "Oh, Teacher Qin, for now, there is only this one......"

"Have a qualification? That's okay. Qin Ming said.

"No, I don't know how to say it, although it seems to be well-structured, but ...... There's a structure in this drawing, and I haven't seen ......."

"Oh?" Qin Ming raised his eyebrows, "I'll take a look." ”

Qi Jiuyuan handed the drawings to Qin Ming.

Soon, Qin Ming looked at it, indeed, this drawing looks like it, from the functional point of view, it should be a mecha for transportation, but this structure is just this ......

"Replace AE644 with AE583, the strength ......" Qin Ming also fell into deep thought.

"Teacher, the strength of 583 is not enough." Qi Jiuyuan said.

Qin Ming shook his head, "Although the strength of 583 is weaker than that of 644, it is not too weak...... It's better to replace 644 with 583, but there are still many parts of this structure that I don't quite understand, and I can't see what the intention is......"

Then the two of them swept through the remaining drawings, and in the end, they still didn't see anything qualified.

"Teacher, is this a qualification?" Qi Jiuyuan asked.

Qin Ming thought for a moment, then smiled, "Take it and try it, you'll know." ”

"Try?" Qi Jiuyuan was stunned.

The experiment of a new mecha is not so simple, the cost alone is a problem, although it can be reimbursed, but they can use such a large amount of effort to verify this mecha for such a large class fee?

Qin Ming naturally knew Qi Jiuyuan's doubts, and suddenly let out a "hi".

"Whoever asked you to do it directly, just try to see if the structure is reasonable, after all, the structure of the other parts has not changed much."

Qi Jiuyuan suddenly realized, "I see, it's a good idea, the people of the Mecha Society are working on a new structure, just let them try it." ”

The Mecha Society is one of the largest clubs in Meteorite Academy, so they also have a lot of professional equipment, so it's the best fit for them to test.

Two hours later, Qi Jiuyuan got the results of the report, which made him a little stunned.

The structure is reasonable, and the cost is lower than the current structure for industrial production, of course, not much lower, just lower, and there is nothing else left.

This strange result also made Qin Ming a little puzzled, after all, in their opinion, most civilian light mecha have already achieved automated production, and no one will be bored to study how to reduce the cost of light mecha.

But in any case, this is the only feasible design drawing, and Qin Ming still decided to approve it.

Of course, it is not for nothing that the tuition fee will be reduced, and you still have to pass a certain difficulty exam to enter the Meteorite Academy.

It's just that when Qi Jiuyuan saw the name on the drawing, he found that it was a little blurry, and it should be that those people from the Mecha Society accidentally stained it.

"I remember it was like ...... Leaf stone? Qi Jiuyuan frowned.

Qin Ming glanced at it, "The name is dirty, it doesn't matter, those who can come to my class have a certificate of attendance, just go to the Academic Affairs Office to check." ”

So this matter was thrown to Qi Jiuyuan by Qin Ming, but when Qi Jiuyuan went to check the list of those who had hearing permits, he didn't find anyone named Ye Shi.

In desperation, this matter could only be stopped, Ye Shi was the attendance card from Uncle Rong's hand, and it was naturally not his name on it, and even if he learned the news, he might not necessarily take the exam, he didn't think that his level could pass the exam of the Meteorite Academy.

So Ye Shi's life returned to its usual state, repairing 5 mechs every day and going to the garbage mountain every few days, but because of the reason for taking that course these days, he already had some experience in the design of light mechas, and it was almost the actual manufacturing.

In fact, he can try to build a low-cost mech on his own, and then use it not for sale, as a design verification, so that the cost is not too large.

As soon as this thought came out, it was irrepressible.

This was only to verify the feasibility of the light mecha he designed, and he never had the luxury of selling it, in today's era when mecha for various life purposes are all over the world, even he really has no idea about the innovation of light mecha in terms of function.

And if he masters the design of light mechas, he will undoubtedly be more proficient in the maintenance of light mechas, because he can know some maintenance principles.

Soon, Ye Shi decided to give it a try, otherwise he wouldn't have made any progress at all.

Turning on the communicator, he quickly retrieved a large number of mecha parts from the translucent light curtain.
