Casings of various forms are used to house different kinds of products. For example, electronic products need suitable casings to house electronic components for such electronic products.
For portability, product casings should be made to be light weight. Market studies suggest strong consumer preference for light weight products over heavier products in the marketplace.
However, there is also a need for products and their casings to be rugged. While attributes such as strength and ruggedness of casings may be increased by using more materials, this can make them thicker or heavier, and therefore less desirable to consumers, for the reasons just discussed.
Strength requirements for portable product casings can be particularly demanding, since portable products tend to have a higher likelihood of being accidently dropped. When portable products are dropped on hard surfaces, the shock of the drop can induce substantial mechanical stress on product casings. If product casings are seamed together, sufficient mechanical stress from extreme shock of a severe drop event can cause seams of the product casings to fail.
Thus, there is a need for improved approaches to housings for electronic components.
Improved techniques are disclosed for housing electronic components. A first housing member can be made to have an exterior surface that covers a majority of the housing. The first housing member can be of unitary construction. The first housing member can be seamlessly constructed. The first housing member can be formed in one injection molding.
