Product design functionality

Functional Blends. The term functional blend refers to various ingredient blends formulated to achieve a certain objective such as fat reduction. An example of this blend consists of water, partially hydrogenated canola oil, hydrolyzed beef plasma, tapioca flour, sodium alginate, and salt. This blend is designed to replace animal fat and is typically used at less than 25% of the finished product. Another functional blend is composed of modified food starch, rice flour, salt, emulsifier, and flavor. A recommended formula is 90% meat (with 10% fat), 7% added water, and 3% seasoning blend... 

Toughness is not simply a function of polymer structure or the mode of stressing. It clearly will also depend on the temperature and the rate of striking but more important still it will depend on the product design and method of manufacture. 

Although there is no limit theoretically to the shapes that can be created, practical considerations must be met. These relate not only to product design but also to mold or die design, since these must be considered one entity in the total creation of a usable, economically feasible product. In the sections that follow, various phases considered important in the creation of such products are examined for their contribution to and effect on design and function.

The functional approach to products and processes, sometimes known as product design , or more specifically for this book green product design , has also been used as a basis for discussion of the different metrics approaches that stimulate R D and implementation of new concepts. 

Structured products, such as cosmetics, detergents, surfactant foams, inks, paints, drugs, foods and agrochemicals, combine several functions and properties in a single product. Design of these structured products involve the creation and the control of the particle size distribution in operations such as crystallization, precipitation, generation of aerosols, and nanoparticles as well as... 

A mixture of acetone and chloroform is to be separated into pure products [Hostrup et al. (1999)]. Since they also form an azeotrope, one alternative to satisfy the separation objective is to find a suitable solvent for separation by extractive distillation. This type of problem in product design is usually encountered during the purification or recovery of products, by-products, reactants or removal of undesirable products from the process. Also, it can be noted that failure to find a suitable solvent may result in the discard of the product. Alternatively, a functional chemical product manufacturer may be interested to find, design and develop a new solvent. In this case, the solvent is the chemical product. 

As mentioned, chemical product design requirements can come about because of desires for a totally new product, complaints about the functionality of existing products, and/or the failure due to malfunctions of existing products. Therefore, there are several kinds of chemical product design problems. For instance those ruled by structural decisions, those ran by functional decisions and those that depend on both factors. Let us consider the design of perfumes to explain theses cases. 

The product that is a homogeneous fluid solution has different components to perform various functional roles. The product designer has available more design variables to manipulate, and needs to balance their proportions to achieve the desired customer performance and company profit. Let us consider the design of a guided-missile fuel intended for the Tomahawk, which was used prominently in the opening phase of the invasion of Iraq in 2002. 

The majority of students trained in chemistry and chemical engineering who enter industry will work in product-related functions, yet few receive formal training in product design and development. ...
