Contest Brief

Hi,
I want a simple device to be designed by that you can check, since when a bottle of water is opened. This electric device should be put to the closing cap of a water bottle (fitting easily and properly to closing caps of different common (European) sizes).

When the bottle is opened you press on that device.
The first day the device shows green light (e.g. LED), this means the water in the bottle is still consumable.
The second day it shows yellow, meaning the water still alright, but not fresh anymore.
After that day the device shows red, meaning water is not good anymore (hazard of germs, etc).

The device should fulfill following requirements:
-high quality design and material
-nice, decent and minimalistic design
-simple in use (e.g. only on push button), changing color easy to recognize
-easy to attach on common bottle cap sizes
-easy to detach, when bottle is wasted
-can be use several times, meaning not single-use
-low battery consumption, energy lasting long, changable button battery
-although I don't need final engineering now, the design should be feasible for mass production in a later stage (mass production price max. 2-3$ per piece)

Nice to have, but only if the design is still good:
-the device makes opening bottles easier (e.g. for kids and seniors)

What I need:
-Feasible Concept
-Rendering for showing investors
-Concept for a protoype (3D-print-file + simple electronics-concept), so I can let this produce for making a promotion film

Kind regards
Martin
