While there is much good design about, there is also a lot of bad. Furthermore there is bad design produced by ?people/companies?/brands? that pride themselves in good design.
These are my current offerings simply because they are of a size and scale that can be photographed. (Some day, sometime, will someone please photograph department store layout (e.g. IKEA), traffic lanes and pedestrian walkways that leave one shaking in fright or despair!)
[1] The container for V8 Vegetable Juice Original. Back of box states "Campbell Foods, Belgium".
Look at the foil disc that stays as a flap at the opening once the green cap is (with great effort) screwed off .... a perfect medium for germs.
[2] The plastic container for Ocusan eye drops. The plastic is so thick/stiff that, even using 2 hands to squeeze out the watery liquid (while trying to aim the drops correctly), I usually end up abandoning the effort.
[3] Leather watch strap with buckle. The top photo shows how it sits on my arm. The straps are sufficiently unequal to make the topside clock face and the buckle sit weighted to each side. I have tried putting an elastic band on one side to keep it from sliding around... about 40% successful, i.e. it stops it sliding completely out of sight!
[4] Espresso Coffee Machines. No, it is not the noise of them that rates an entry here, it is the milk heating jet and the practice of cleaning it (or not). Next time you stand at a counter waiting for your espresso look at the way the equipment is laid out and used. When they go to make you latte or whatever, they take the cup up to the milk jet (white arrow) and the jet heats everything up (or whatever it does). When the cup is taken away, the dripping metal jet is either left as is or wiped with a cloth*.
In this photo, from Wikipedia, it actually has a wine coloured cloth hanging on a hook (blue arrow). Milk is one of the best media for growing germs; cloth or no cloth - this design guarantees it.
* Watch how it is usually a J-cloth and it's the one that is used to wipe the spills on the counter or trays ... you get my drift!
