Bike Pack
Many companies have tried to do this with on road bikes. (Toyota, BMW)
Problem: structural integrity and wheel size
GlassHolder
Why? Just as stable with glasses flat on plate. The bottom of the glass isn't heavy enough to act as a ballast for the top of the glass filled with liquid. The glasses would have to be pinched in there pretty tight for them to not wobble around like crazy.
Traffic Signal with Hour glass timer
Too difficult to judge that at a distance. That's why we use different colors.
Solar Charging while Parking
That is one waste of money. If you are in a parking lot then you are near a building that you can run power from. That would be a LOT cheaper than that quarter million dollar lamp-post.
No more Blind Spots (rear view mirror)

Wearable wireless mouse
It's been done multiple times and they all fail on the market.

Hidden Power Outlet
Very common on college campuses. Most study tables have these and they suck ass. Pain in the tush to plug-unplug. (they are not strong/stable)
Unique umbrella design
Where do you think the water is going to go when it runs down the side of that thing? Straight into her waist. Water wicks along the surface and shots off the end.
Ruler with holes for precision
Under normal tape measure usage the metal band would have stress fractures running between all the holes.
Eco friendly Toilet
Soap scum buildup would be a bitch to clean out of that pluming nightmare. Putting grey water into the clean water input is not a good idea.
Solar rocking chair
Why? I don't see the purpose. So you can sit in the chair for 6 hours straight without your phone battery going dead? Also you would have to get up and turn the chair every hour.
Also that's a really expensive lawn chair... who would buy that?
Digitally precise protractor
Been around for a long time....

You will have no problem finding the keyhole
Um... why don't we have this yet?!
For smart parents
Not a bad idea... market is very very small though since that bike has only one purpose and is useless as a normal bike.
Bicycle Parking
Extremely inefficient (space wise) and expensive way to store bicycles.
Digital Measuring Cup
Why is it easier to look down at the handle then to look at the sides? The numbers are the same size.
Built-in Wall extension cord
Absolutely terrible idea... What are you going to do when it gets tangled inside?
Also, houses are designed with enough room in the wall for that.
iPhone Lens
Been around for a long time.

Spoke-less bicycle
What problem is that solving? Also, those wheels would be heavier to make up for lack of structural integrity of not having a core. (VERY flimsy wheels)
Compact Boots
When would you ever actually zip them up... for real?
Digital Ink for Tablets
Or you could just take a picture and use the ink-dropper tool.... instead of spending a $50 for a pen you will lose.
Solar Charges + Window Stickies
Why would you use a solar panel inside?! There's prolly a wall outlet 2 feet below that window. Also.. that window will take 50% of light energy and the bad angle-to-source of the window will take another 30%
Knives Set
That's inconvenient if you want the knife in the center.
Also, the top of the knife would hit the vegetable if the center of the knife is hollow.
Rubik's cube for the blind

Zipper Ear Phones

Self Locking Bike
Heavy and not structurally strong enough to ride... also won't work on bike rack
Calendar Ring
Why? Just look at your phone.
Solar Powered Camping Tent
Why? You set the tent up at sundown ... and then there is no sun...
