Roladex Clock

Posted in 2. Buttonless Clock on December 17, 2009 by zingzhang

So… I know this is months late… but I was looking through my posts to make sure I hit each assignment, turns out, I never did this one. Mark, if you accept this 3+ months late… you’re awesome. Either way, thought it wouldn’t hurt to post it:

My idea for this is pretty simple. Remember the roladex?

well… imagine two roladex type objects.  One would hold the numbers 1-12 or 1-24 for military time, and the other would hold numbers 00-59 for the minutes.  The two would be hung side by side and to change the time, all you would have to do is rotate the corresponding knob through to the appropriate spot.

This goes without saying, but during normal operation, the cards would flip through automatically.

The clock i came up with uses 3-axis accelerometer to sense the clocks positioning. The clock is designed to be hung upright on a wall. When the clock is taken down and placed flat, both short and long hands will stay still. To change the hour, rotate the clock while facing UP until the short hand is pointing at the desired hour. To change the minute, do the same while facing DOWN.

Bike Pump Clock

The bike pump clock would use air pressure to manipulate the clock’s output. Pumping more air into the tire moves the clock hands clockwise. Releasing the pressure from the tube’s valve would move the clock hands counter-clockwise.

Tangible Time

This clock uses two scales weighing metal ball bearings to determine the time. The Display is made up of a Transparent front panel behind which metal bearings accumulate as the day goes on. The bearings come from a reserve under the clock where they roll down a chute and are carried to the top the the display by a precision timed magnetic wheel. When each side of the clock reaches its limit the display empties just in time for the next hour or minute to be deposited.To adjust the time one has simply to add or remove  bearings from the face of the clock.

The alarm feature works in a similar way, there are two cups on the top of the clock (one reserve and one weighed) filled with bearings of many different weights and sizes. To set the alarm you simply adjust the weight in bearings in either cup and watch the readout on the main display adjusting the alarm time. Clock

Eventually you get a feel for how heavy an hour is.

The Roaming Clock

Roaming Clock

I designed a clock based on gravity.  It is approximately 2 feet in diameter and has one large hand.  In order set the clock, one must push it one notch counterclockwise. Gravity then drags the hand straight downward, and the user can roll the clock to whatever time it is based on one of twelve notches on the side of the clock.  To re-enter time mode, the user once again roles one notch conuterclockwise.  When the clock is set, it rolls so that the hand always faces directly upright all day, and the number rotate.  The clock moves in a cricular pattern, and its location is predictable based on time of day.

Not recommended for small rooms.

1) A clock that can determine whether or not it is being held upside down. The user flips into “set time” mode by literally picking up the clock and flipping it upside down. While upside-down, the user can rotate the clock towards them to move the time forward, or backward to move it backward. The time is set by re-righting the up side of the clock.

2) A clock with two handles, one on each side of it, which can be gripped and twisted. The user picks up the clock by the hands and twists with both hands to set the time in either direction. You would twist the left handle towards you and the right handle away from you to move the time forward, and you would twist the left handle away from you and the right handle towards you to move the time backward. Yes, the affordances on this clock would be tricky, but honestly I just like picking things up and twisting them like that – setting your clock is annoying; making it like squeezing a towel might let you take some of your anxiety at the situation out on the clock. 🙂

This clock fills from left to right while seated horizontally – giving the viewer an impression of relative, not absolute time.

To set the clock, the user rotates the clock vertically or horizontally and allows the ‘liquid’ to ‘pour’ away, the tilt letting hours or minutes out.
