When I started to think about products that have faults in their design, strangely enough the first thing that came to mind is my dads whipper snipper also known as an edge trimmer. This probably sounds like an odd product to come to mind, especially for a girl but I help mow and trim the lawns, and trimming using this whipper snipper has become a huge long process.
The whipper snipper my father owns is a Ryobi, 2 cycle petrol trimmer. The main flaw in the design is that the starting up sequences is to long and complicated. Edge trimmers are meant to make mowing the lawn easier and tidier, but neatly cutting the edges of the grass, so why make the starting up process so unnecessarily long and difficult.
Steps to start the edge trimmer:
1. Put ignition switch in the ON position
2. Fully press and release primer bulb 5 to 7 times (Fuel should be visible in the bulb)
3. Place the choke lever in the FULL CHOKE position
4. With the unit on the ground squeeze the throttle trigger and pull starter rope briskly until the engine sounds like it wants to run
5. Place the choke lever in the PARTIAL CHOKE position
6. Pull starter rope briskly 1 to 3 times to start the engine
7. If the engine does not start repeat steps 3 to 6.
I do not understand how this products starting process needs to be so complex. The design of this product needs to have a look into this starting process because its to difficult. It would be so much easier if you only had to push one button or put one lever in a position then pull the starter rope to make it start, similar to how mowers start.
Although other than this long process for starting up, the main rest of the design is very good, and satisfies the needs of the users. By helping to cut the edge of grass areas neatly it makes a mowed section of grass look neatly cut and fresh.
