The Reason Why Apple Uses Integrated Battery Designs

They are foremost about a cohesive experience that is enabled by technology. That would mean that the primary purpose of the non-removable battery in Apple's gadgets is not to annoy you, or to deliver additional revenues to Apple stores. The purpose would be experience, right?

Well, that is what an Apple patent filing that describes an "integrated embedded battery" appears to outline as well. The patent claim simply explains "a plurality of battery cells, wherein each battery cell is directly attached to a housing for enclosing operational components of the portable computing device, […] wherein the protective structure is configured to protect the battery cell from a compressive force applied to the housing of the portable computing device, the protective structure being attached to or integral with the housing and having a height greater than that of each of the battery cells."

However, the background description of the filed patent is much more revealing. In fact, the reasoning behind Apple's embedded battery is a great example of Apple's thinking behind the design of its products. Apple explains that the design of compact portable computing devices means that there can be "complex tradeoffs" and notes that the battery may be such a tradeoff. The design of the device can affect the battery in its general type, its energy density, durability and packaging.

As a result, Apple says that its embedded battery is a solution for a "portable computing device that is durable, lightweight and efficiently packaged." The description of this specific embedded battery shows an extraordinary amount of attention to the goal of supporting the design of the device as experiences by the user. For example, there are structural "ribs' that protect the battery from compression, but are lighter than a structure that would need to be present were the battery removable.

For replacement purposes, the battery was designed - even if consumers cannot replace the battery themselves, for easy removal: "As the battery cells are not enclosed in a separate pack, they are therefore easily accessible. Thus, the lack of a separate pack makes it easier to identify and repair or replace faulty battery cell. A removal mechanism, such as a pull tab or a removal handle, can be attached to the battery cell to facilitate removal of a battery cell that needs to be repaired or replaced."

    They're trying to patent that horrible idea? Good, maybe then no one else will be so stupid as to try it... That was initially my biggest complaint about the iStuff... Consumers NEED the ability to replace the battery or you are greedily forcing them to spend big $ on maintenance and/or replacement. That, IMHO, is akin to gouging with our dependency on electronics today. While I'm not an Apple fan myself, this one one of the enormous "avoid at all cost" items that they continued to do which just made NO sense to me.

    how long before apple sues dell for the OLD Pentium 1 era laptop that had a battery you couldnt remove without desalinating the case... seriously...

    "a plurality of battery cells, wherein each battery cell is directly attached to a housing for enclosing operational components of the portable computing device, […] wherein the protective structure is configured to protect the battery cell from a compressive force applied to the housing of the portable computing device, the protective structure being attached to or integral with the housing and having a height greater than that of each of the battery cells."

    so are they going to sue radioshack for some of their phone designs?

    another vaguely worded patent that could lead to trolling... at least they HAVE WORKING MODELS +1 for not patenting air... oh wait.. apple will name some new uber small laptop the apple iAir or something...

    This is pure BS of patent and will hurt other manufacturers who have batteries also embedded to back cover, back plate or w/e they call it. Two reasons are why this patent and idea of embedding battery is bad. Patent is BS because it's same as if someone tried to patent knifes with folding blade. It's already existing technical solution and because of it's wide usage it belongs to public domain. Not to mention previous art argument, heck I remember 7 years ago I had dumb phone with embedded battery.
    Embedding battery is bad because all protection from pressure mechanisms can be implemented in battery itself, while leaving back cover unattached to it. The problem is that back cover get scratched from various reasons and why anyone in his/her right mind would have to buy whole battery?

    Anyway I can't prevent wondering how much did mr Perry or Tom's got for this article from Apple, because this is blatant serving of PR BS cooked in Apples kitchen.

    dismantling NOT desalinating.. stupid andriod auto spell check
