The Caterpillar Inc. patent solves the following problem:

In conventional vehicles to build as the wheel payloader, it is customary to put in the same area on two wheels in front and behind the vehicle. While it has been known to work well in most cases, the surrounding area was chosen for each individual car is normally dictated by the functional requirements of the front wheels. From 0 most operational cargo brought in before the end of the vehicle, the functional requirements for the rear wheels is not the same as before. However, in order to maintain the common area between the wheels front and behind the vehicle's rear wheels usually much greater need in normal working conditions. This situation results in an unnecessary increase in the length of the back of the car, in turn, increases the center of gravity of the vehicle and tends to interrupt service. The larger rear tire also tends to increase the wheelbase of the car to make a larger turning radius.

Our analysis of this patent is as follows:

Caterpillar Inc.’s patent US 5379857 A deals with Drive configuration for a wheeled machine.
Construction equipment usually given with the same size wheels on both the front and back of the machine to maintain the common area of ​​the wheel and the simple drivetrain configuration. The present invention provides a smaller pair of wheels at one end of a machine with the pair of wheels to the other end position. In doing so, the total length of the machine with a smaller wheel is reduced. It lowers the center of gravity of the machine to improve operating stability on the machine. Furthermore, the decrease in elevation made the car more accessible and thus improve service.

The Greenbrier Innovations, Inc. patent solves the following problem:

The present invention relates to devices attached to the flexible packaging to assist in tearing open the packaging without using an additional tool.

Our analysis of this patent is as follows:

Greenbrier Innovations, Inc.’s patent US 5378066 A deals with Opening device for flexible packaging.
An opening device for flexible packaging and a package with an opening device bonded gave, where the opening device concentrates tearing forces and provide additional tearing leverage, hold-open packaging without the need for a sharp object that promotes tears. The opening device may use the first and second wings spaced apart from one another on a narrow distance and joined to a proximal end of an integral web, which acts as a fulcrum for each of the wings as they rotated to highlight the tears, or to use the first and second wings or levers on opposite sides of a sealed edge of the package, which levers operate as a common fulcrum in the innermost part of the proximal ends of the levers of development and attention tearing forces. Another uses a lever whose fulcrum is established at a point where a lower edge of the contact lever, by the thickness of the packaging material, a face of the product in the package, and the load located in an upper area of ​​a bonded regions joining the packaging material at the proximal end of the lever.
