Design Technology: Thin Wall Part Design

From failed smartphone models whose housing covers deform or break, to electrical switches that fatigue and stop operating, there are enough products from large multinationals that have experienced failures in the marketplace - often due to poor thin wall part design.

The scope for "overdesign" or "underdesign" is limited while designing thin-wall products; they must be developed to perform their function in a very tight range of design, manufacturing and "use" and usually are not designed for high factor of safety for withstanding "abuse".

Thin walled products lower the environmental impact and energy used in making those products; at the same time, provide for extremely fast manufacturing by reducing production and assembly cycle-times.

Lightweight products with thin walled plastic and metal parts and hybrids, are increasingly being developed to reduce component weight and raw material use, and for acheiving tailormade performance. Thin wall part design techniques offer total design control and predictable performance over the service life.

As the newgen products continue to become more smart and compact, packing a lot more user functionality, there is growing need to make them light weight yet robust. Smartphones, Wearables and personal assistants are some of these examples. For the industrial designer, product styling and finishes matter more and for the design engineer, the assembly performance and reliablity! As these combine the challenge to design optimum thin wall parts becomes critical and highly specialized area.

In this module we shall learn to optimize design techniques for thin-wall parts and look at the ways of increased reliability extending service life without increasing the part weight.
