"Remote" Control Car

PROBLEM:


Pictured here is a "remote" "control" car.  The reason I use quotes is that the car's controller is connected to the car with a 5-foot-long wire.  This design eliminates the remote nature of the controller and therefore much of the mobility.  The user has to run alongside the car for it to really go anywhere.  Where is the fun in that?  I also put quotes around control because control for this car is a possibility of two different inputs.  The user can push the red lever forward or pull it backwards.  The car then can only go straight forward or straight backwards.  Again what fun is that?  The design of this car, although it makes for a cheap product, doesn't factor in the user or the use case.  The satisfaction provided by this toy is unbelievably limited considering the design doesn't even allow for its intended use.


SOLUTION:


The solution for this problem is relatively simple.  Wireless technology is very common in this day in age, and a wireless transmitter could be installed very cheaply.  The transmitter could have a range as small as 10 feet and still accomplish its desired result.  This system needs to be able to send and receive four simple user inputs.  Forward, backward, left, and right.  This could be done simply by adding another lever to control turning the wheels left and right.  With these two very simple changes, this system could be a true remote control car and the satisfaction it brought to the user would be greatly increased.
