Refrigerator doors are hinged at one side only.
This is simple, but inconvenient.
Since a supply of electrical power is continuously available, there is no reason why a fridge door shouldn't be hinged at both sides.
On the new BorgCo design, both sides have conventional hinges, but they are
not fixed to the frame. Instead, they mate into a mortise on the upright section of the fridge body and are retained by solenoid operated bolts.
When one side of the fridge door is pulled away from the casing, the tension is sensed and the bolts on that side release, thus the door pivots smoothly on the hinge at the opposite side.
The existing magnetic seal is retained in this design. Since it is likely that the mode of operation will be consistent, when the door closes it is retained only by the seal; only when the currently "fixed" side is pulled do the bolts change over, first locking the "free" side and then releasing the "locked" side. This process occurs so quickly that users are barely aware of it, apart from the loud "THUMP - BANG - CLUNK" as the solenoids actuate.
If power fails, the bolts remain engaged; a manual release lever at the top allows only one side or the other to be released if required. The door must then be fully closed and latched before the bolts on the other side can be disengaged.

Put hinges on the left of the door which attach it to a very
slightly larger outer door, which has hinges on the right to
attach it to the main fridge. |
|
| |
Wrongfellow beat me to it. |
|
| |
Why not just a frame-in-frame style where the door is
hinged to a hinged frame? |
|
| |
You're no fun any more ... |
|

I blame parenthood. Now, please stop teasing your
sister... |

You could always opt for one of those French door
style fridges. I know it would take some humbling to
accept something with the word 'french' in it, but
you could always call it something else... |
|
| |
[+] but I'm unsure why you need electricity to operate the door. |
|
| |
The door is hinged and handled on both sides. Pulling a handle pulls the bolts out of the hinges on that side, and the door swings open on the still connected hinges on the other side. |
|
| |
I dunno, if you could make some different groceries appear
the next time someone opened the fridge, you’d be pretty
popular. How many people reopen it hoping to find
something different? |
|
| |
I think [FT] has this one nailed. Admittedly, his proposal
lacks complexity, fallibility, inability to open the fridge
during a power cut, expense and noise, but it still nails it. |
|
| |
Trickier than it seems to make work; if you’ve ever tried to
punch a pin out of a door hinge, you’ll know that usually a
hammer is required. |
|
| |
Don’t grab both handles, the door will fall off.. |
|
| |
[RayfordSteele], actually, that could be an advantage. Makes cleaning and maintenance easier. |
|
| |
Maybe instead people should have two hands, one on each side, so
that they can open a fridge regardless of which way it's hinged? |
|
| |
Or you could have a fridge door with no hinges, so
that when you pull the handle it just falls off onto
your foot, and when you've finished getting stuff out
of the fridge, you have to carefully manoeuvre it
back into position. |
|
| |
Or you could have a fridge door that opens upwards,
like a car tailgate. In fact, if you turned actual car
tailgates from classic cars into fridges I'm sure there'd
be a market for it. |
|
| |
Sharp have a fridge on the market with this feature. See link. |
|
| |
//a fridge door that opens upwards// ... wouldn't allow you to store
things on the door shelves. |
|
| |
Yes it would, but you would have to load the shelves from the inside while the door was closed. |
|
| |
Nice one, [EL], thanks ... <scribbles on shopping list/> |
|
| |
I'm mildly surprised no one has suggested the
'iris'-opening fridge door |
|
| |
1. You can't store stuff in the inside of the door. |
|
| |
2. The iris doesn't provide good insulation - to fold away effectively, the segments need to be thin. |
|
| |
3. There were negative reports from the test team when - on several occasions - the iris closed unexpectedly and with considerable force, severing the user's forearm just above the wrist. |
|
| |
All good points, although I might reflect that
inconvenience and risk of serious injury are not
usually objections to Halfbakery ideas.
OK
then, what about the Sphincter Fridge Door? |
|
| |
1. Vile and disgusting mental imagery. EEEEwwwwwww NASTY.... |
|
| |
The iris design does have the singular advantage that the severed portion of the limb is kept chilled, allowing time to organize the microsurgical team to attempt reattachment. That only applies to humans; Borg can just slot a new manipulator into place from a range of stock designs. |
|
| |
//the iris closed unexpectedly and with considerable force, severing

|
| |
I doubt that particular firmware feature will meet with regulatory
approval down here on Earth. |
|
| |
//Vile and disgusting mental imagery. EEEEwwwwwww
NASTY....// - Thanks! |
|
| |
// regulatory approval // |
|
| |
Indeed. Worse, in between bouts of screaming, the tester threatened legal action. |
|
| |
Fortunately we came to an amicable arrangement whereby we simply removed the torniquet, after which they bled out surprisingly rapidly. |
|
| |
Since there were no death-in-service benefits for zero-hours contract staff, there was no need for a payout, or even an insurance claim. A few minutes with a pressure washer and cleanup was complete. |
