Ergonomics

The designs of new inventions have to fit many criteria to suit the title of a successful invention. There are five areas that a good invention are criticized towards to make it a purposeful invention: safety, comfort, ease of use, performance (productivity), and aesthetics. The design I have chosen is a doorstop shaped like a little person that is attempting to stop the door. This doorstop design is successful in many ways making it a useful invention, but it also has its flaws.

The doorstop poses as a safe invention. They are there keep doors opened so that they are not a hassle to constantly open the door as well as keep doors from closing on people. At the same time, it can also pose as a safety hazard because people can trip over it because it is larger height-wise and width-wise than a regular doorstop. Although people may see it and walk over it, those that miss it, this doorstop is high large enough to trip a person if it is not out of the way from a person's walking path. Still, the doorstop is useful and does what it's designed for.

As for comfort, this doorstep does not pose as any comfort for people. It may possibly be useful enough for people to stay comfortable with whatever they are doing without having to hold a door open. The doorstop could also be comfortable for the door because it does not leave marks or scratches on the door. It helps the door keep in position for however long it is needed to.

This invention is very easy to use. It does not take too much effort or time to utilize. The ease of use is really efficient because the doorstop is just placed at the correct location and it simple does its job. The doorstop does not require supervision or work because it does what it needs to and save the trouble for people. Also, the invention does not take a genius to know how to use it, so its ease of use is easily understood by many. 

The performance of the doorstop is quite efficient and useful because it gets the job done. The doorstop was created to stop doors from closing or to keep it opened saving people the effort to doing so themselves. It performs just the way it needs to and have to. The invention is able to hold the door in place for however long it is needed to.

Aesthetics of this invention is highly attractive. It caught my attention right away because it has a clever design. The design is of a little person trying to push the door to stop closing or to keep it opened. It is an unique idea because that posture of the design is like a human's position when they are using their full strength to push something. It also comes in different colors for those that prefer another color other than black. The doorstop is also small enough to not take up too much space when stored away or when in use. The design is a simple stick-figure character, but the creator was able to utilize that idea into a doorstop, which makes it a useful design.

This invention has its pros and cons, but its pros outweigh the cons. With this attractive design, it is able to easily capture the interests of people of all ages. Although the invention may not be all safe and provide physical comfort for a person, it is able to perform what is is designed for as well as have a clever aesthetic.
