Note 7 : an independent study puts into question the design “too … – The Digital
A battery too small
While the internal investigation of Samsung continues its journey to try to discover the cause of the explosions of the Galaxy Note 7, an independent research firm, has conducted his own tests and thinks to have discovered the reasons that led to the Note 7 to its loss.
While the twists and turns morbid the Galaxy Note 7 seemed to quiet down recently, engineers outside of Samsung come to explain to have found the cause of the explosion of the mobile before Samsung itself, which is still continuing its investigation. According to instrumental.I this is the design called “too aggressive”, which would have caused short circuits in the battery and thus causing explosions.
While the twists and turns morbid the Galaxy Note 7 seemed to quiet down recently, engineers outside of Samsung come to explain to have found the cause of the explosion of the mobile before Samsung itself, which is still continuing its investigation. According to instrumental.I this is the design called “too aggressive”, which would have caused short circuits in the battery and thus causing explosions.
As some of us suspected, this would be the construction of the mobile that is at issue and not the battery directly. According to the study, the body of the Note 7 was too thin and too narrow to let the battery “breathe”. The engineers explain that the Li-ion batteries have a natural tendency to swell when the current passes through the different layers. In the case of the Note 7, the space for this swelling missing, the layers of positive and negative of the battery come into contact, which would lead to the famous explosions. Circumstances aggravated by the normal use of a smartphone that can sometimes be subject to slight twisting.
Security against innovation
What Instrumental.ai notes, is that in seeking the balance between security and exceeding limits, Samsung would have looked a little too much on the side of the second edge. The increase of the thickness of a battery is the simplest solution to increase capacity, the Korean company would have pushed the limits a little too far and would have disregarded the principle of leaving at least 0.5 mm of play between the battery and the hull. So far, Samsung had taken some safety measures by integrating the battery into a space that is isolated from other components, precisely to avoid the contacts. Brutal competition, therefore, would have had reason to Note 7. Wanting to make phones ever thinner than the competition with batteries always most important, Samsung would be a little too played with fire. And if safety tests have no doubt been made, the engineers seem to think that in the course of the changes in construction, all the different revisions would not have benefited from a test on the long-term enough. One more proof that the race for the finesse is probably not the axis most important development on smartphones today.
“The primary marked the decline of the énarchie,” notes Nicolas … – RTL – RTL.fr
“As François Fillon, Manuel Valls is not of this caste énarchique. in Any two are the same anti-patterns“, analyzes Nicolas Domenach, according to which, “in the two camps, the rout of these excellencies is awesome”. To the right, the defeated are the énarques : Jean-François Copé, Bruno Le Maire and Alain Juppé. “They are certainly not of the same promotion, and are not reducible to their matrix énarchique, but they all bear the mark, and without a doubt the release that the hit comes it from here,” said the reporter.
To the left, the énarques are no longer in the race. “It is as if these beasts to contest had disappeared with François Hollande. To the dustbin of History, the best of them all !”, clamp-t-he. “We have not learned to énarques to take risks, but to overcome the obstacles as they dodge”, adds Nicolas Domenach. “Gold Arnaud Montebourg and Manuel Valls are more the type to rush straight into the wall for the sink and honking. It is the school of the street and the ballot box”, decrypts there yet.
“To succeed in their career, Fillon and Valls rose while waterskiing behind the mentors are illustrious (Séguin and Sarkozy for the first ; Rocard, Jospin, and finally to Holland for the second), recalls Nicolas Domenach.
Note 7 : battery dangerous because of the design “aggressive … – ZDNet France
Samsung has promised to deliver before the end of the year a clear explanation about Galaxy Note 7 of which the battery has a tendancy to overheat and ignite. In the meantime, the independent engineers also looked into this matter and communicate today their conclusions. They seem to confirm the first few tracks-namely, that the battery is not the only cause.
According to Instrumental.I, the battery can not physically enough breathing
We are facing a conjunction of elements : the battery has been rendered dangerous because of the design “aggressive” of the smartphone. By “aggressive”, it means “too late”. In this race to the finesse (the Note is only 7.9 mm thick, Samsung is perhaps going too far since the chassis would place pressure on the battery, as the compartment that receives the battery has been reduced to the maximum.
Thus, instead of having 0.5 mm of space to “breathe” in the battery, the battery of the Note should merely 0.1 and 0.3 mm of margin as shown in the photo above. However, in use, the battery has a tendency to somewhat swell up…
This pressure, as well as a physical divider anode/cathode end too have helped to promote the phenomenon of thermal runaway, which occurs when there is a short circuit between the cathode and the anode, and therefore a risk of fire.
The question now is whether this risk was not known from the design of the device. Samsung he wanted to go too fast to cut grass under the foot to Apple and its iPhone 7, at the risk of playing Russian roulette ? For the site Instrumental.have to the origin of this investigation, there was in any case not photo : “Samsung has clearly failed in its tests of validation of the design and delivered a dangerous product”.
Galaxy Note 7 : in the end it is his design to be “too aggressive” … – Phonandroid
While Samsung is still in the process of conducting the investigation and that it promises an explanation before the end of the year, engineers also studied the question of explosions in the Galaxy Note 7. According to the findings of the business instrumental.I, the fiasco of the Galaxy Note 7 could be due to a problem related to the design of the terminal.
The case of the Galaxy Note 7 appears to already be ancient history, however, Samsung is always at work to try to understand the origin of this fiasco in history. If the Korean had initially estimated that the concern came from the batteries, he finally deceived. The company has therefore decided to investigate more rigorously.
Thus, to this day, Samsung has still provided no explanation but the brand has promised to clarify this whole thing before the end of the year. In the meantime, other engineers were interested in the problem. It must be said that in engineering terms it is a real riddle that unleashes the passions.
design issues
Thus, the company is instrumental.I studied very precisely the question and has delivered its conclusions. And while for the moment all the explanations you made turns battery problems, instrumental.I concluded that the design ” too aggressive “ was at the origin of the explosions of Galaxy Note 7.
According to the engineers of the company, it is the design of the smartphone that would be in question. According to them, the battery of the smartphone swells in as lithium migrates into the battery. There is therefore space in the battery for it to breathe. We are talking here about something of the order of 0.1 to 0.3 mm. If this space is not present, the battery is not “airy” and overheating up to the explosion.
To analyse the problem and check their hypothesis, the engineers have just acquired a Galaxy Note 7 and subjected to a test protocol. They have, therefore, subjected the battery to a series of compressions and observed the chemical reactions of different components.
They then realized that Samsung’s engineers had played with fire. They have, in fact, trying to find the right balance between a design to propose a design that is extremely thin and sleek while reducing the risk of explosion.
Samsung has played with fire
The problem is that reducing the risk does not eliminate it. the Samsung would have therefore wanted to maximize the capacity of the battery without having impact on the design of the Galaxy Note 7. And the result is the one that knows. The company is instrumental.I explained :
Samsung’s engineers are smart. Innovation means pushing the boundaries. To design something innovative, designing the best tests, and validate the fact that the design is correct with these tests. Battery tests are long, and thousands of batteries must be tested to obtain significant results. It is possible that the manufacturing process Samsung has been able to change during development, and that the most recent versions of the batteries have not been tested with the same rigour as the first samples.
The engineers instumental.I agree : Samsung has, without doubt, abandoned the security its smartphone to provide a terminal even more efficient and especially to emphasize the design. The conclusion of the company could not have been more clear :
Samsung has taken risks and has designed a dangerous product.
let’s See what Samsung will have to respond to that. It seems unlikely that the Korean recognize you have neglected the security. We expect rather a further explanation. But maybe we will be surprised. Up to now, the Korean has all the same been very transparent in this whole affair is leaving to jeopardize its image. We’ll see you in a few weeks now since Samsung has promised to make explanations before the end of the year. We can’t wait to have the official version. Not you ?

Finally, the design of the Galaxy Note 7 would have caused its loss – Frandroid
Samsung conducts its investigation, but this does not prevent other engineers to investigate. Here are the conclusions of the company instrumental.ai.
weeks after the case of the Galaxy Note 7, the defective apparatus continues to be talked about. In fact, Samsung has preferred to keep anonymity have told The Investor that the internal investigation was still ongoing, but the results should be presented before the end of the year. In the meantime, here are the conclusions of the company instrumental.ai.
As you know, several sources from Samsung have reported different reasons of explosions of the Galaxy Note 7. According to these last, the batteries would be short-circuited : a history of insulating tape positioned incorrectly, with cells that are too tight. These theories all suggest that the problem would be the battery level, Samsung would have pushed it too far with the miniaturization of the battery. But, if this assumption was only part of the problem ? Why have you cancelled the commercialization of the Galaxy Note 7 ?
engineers instrumental.ai think that the fundamental problem comes from the design of the smartphone. In fact, the battery swells as lithium migrates into the battery, so you have to let the battery ” breathe “. For them, this is a story from 0.1 to 0.3 mm, the vast majority of Galaxy Note 7, therefore, would have met with a problem of deformation terms.
so They have acquired a Galaxy Note 7, and subjected to a test protocol. The idea was to compress the battery and observe the chemical reactions between the lithium and the cobalt, the layer of graphite, and layers of separation in polymer.
looking At the design more closely, they have found that Samsung’s engineers have tried to find a balance between the risk of explosion, and manufacturing ultra-aggressive in order to maximize the capacity of the battery, while trying to protect it in-house.
For instrumental.ai, ” Samsung’s engineers are smart. Innovation means pushing the boundaries. To design something innovative, designing the best tests, and validate the fact that the design is correct with these tests. Battery tests are long, and thousands of batteries must be tested to obtain significant results. It is possible that the manufacturing process Samsung has been able to change during development, and that the most recent versions of the batteries have not been tested with the same rigour as the first samples.” .
According to them, ” Samsung has taken risks, and has designed a dangerous product” .
