1. Design Defects in Products Nitesh Bhatia

2. 1. Lock System Defect 1. Key Design 2. Door lock handle design Why is this a problem? 1. Since all keys have almost same design, its hard to find right key from a bunch for a lock. 2. One cannot determine which way door lock handle should be moved to open the lock just by its orientation.

6. Most of the walkers are either flat type or with wheels which does not provide proper grip and support.Possible Solution If Some foot kind of mechanism can be designed to provide proper support and grip.

8. The pressure from the teeth isn't enough to get a grip on the very smooth.

13. The problem is, a person cannot use regular earphones or connect it to home theatre system which was earlier possible in Generation 2 iPods.Good design is as little design as possible. But it should not kill the usability of product. Generation 2 Generation 3
