Any chance of you letting us know what country you are in and your qualifications and experience? I find it a little disturbing that you (seem) to state that you are an engineer but lack the basic skills to even ask for a job (or spell "please" correctly).
What the hell are kids being taught in University now days! (or is your open-ended question actually regarding what is the current state of the mechanical engineering project market in different parts of the world? Perhaps you are a Troll?).
What about designing a toilet seat and flap, capable of fitting of a woolly covers without the flap or seat falling down when used by men. I am forever accused of not aiming properly.

How about a remote controlled adjustable toilet seat. Options:
Movement: up, down, left right, tilt: 10º forward, 10º rearward
Size: enlarges or shrinks from 10" dia. to 24" dia.
Push of a button conversion from round to oblong, split front or not
Temperature control: 7ºC to 30ºC
Lighted seat or glow in the dark
Automatically raises for males (vice versa, females)
Air or gel cushioning (user selectable)
Fully self-cleaning system
Note: WOOLY COVERS not allowed!
Push button acivation of multi-sized balls that rotate internally around the seat to provide soothing massage for tired cheeks. Note: Do not select when split seat option is enabled!
Ok "plz reply", Get to work!

The built in bidet eliminates the need for most paperwork.
I forgot to mention the tilt function. After a preset time of listening to Perry Como croon on the MP3, the seat automatically tilts forward 45º. That means times up or put another quarter in the slot. Put in a dollar and the seat vibrator function comes alive.
Now, if you're the sort of person with a lot of natural rhythm you can press the floor mounted starter which will fire up the "low rider" hydraulics. Those mechanical bulls have got nothing on this baby. Hang on!!!
