I believe the reason is purely commercial. Why would parents buy another box of bricks if there are pictures of so many things their kid can build with only one set? Nowadays there are no alternate models on back sides of boxes. Instead there are some teaser pictures of another sets, and a message "Collect them all!" Isn't it rather obvious? Anyone of ...
The "LEGO Ideas Book" (http://www.amazon.co.uk/LEGO%C2%AE-Ideas-Book-Daniel-Lipkowitz/dp/1405350679) provides many different ideas, many of which can be achieved with simple bricks. It ranges from easy to harder models, which can help develop your LEGO skills over time.
I am also going to recommend Technic as the stronger support option, but I would make the case out of "normal" Lego, and then implement 2 Technic rectangular "rings" around the case at the place of your pillars, joined at the top and bottom (on the top the joint could form the handle). Make these rings or braces by overlapping Technic pieces and joining them ...
Just like in the other question, I would recommend a Technic frame with more depth than your original idea and some plating on top of it. This project nicely illustrates how to build stable Technic structures using beams in triangle configurations.
Generally LEGO Technic structures (pins and beams with holes) tend to be lighter and stronger as System structures (classic bricks). The generally accepted best practice among amateur and professional LEGO builders is to have a light and strong internal structure (either Technic or other materials, like wood or steel) that can then be decorated on the ...
You can try this blog http://legoideas.si/ It's oriented towards Duplo, but similar designs can also be made out of standard Legos.
If you haven't seen it, Sariel's limited slip differential technique might do what you want, but it's a little different than what you are asking for: This setup doesn't provide a clean way of producing a fixed amount of torque to a wheel if it's partner is running free. It instead simply disables the differential if the wheels have been running at ...
