Product Design Specification

If one wishes to predict the future of additive analysis in polymers, it is relevant to consider the prospects of further evolution of polymeric and additive materials the influence of legislation and environment instrumental developments and currently unsolved problems. It then becomes clear that additive analysis stands a fair chance remaining in use for some time, certainly in a strongly competitive environment, which will require improved product design specifications, quality assurance and research for new applications. As ideal production environments are rare, customer complaints will also require continuous attention. Government regulations are another reason for continuous analytical efforts. 

Heavy-duty products, designed specifically for the cleaning of cottons, are illustrated in Table V. 

The next step in a supply chain audit is to examine how capacity is deployed by understanding its product-based allocation, which is related to design choices across locations and product types and across locations. Thus, we will first consider how products can be separated based on their demand volumes and consequent impact on capacity requirements. The next step will be to consider if product design specifications can be standardized to improve supply chain performance. Finally, the impact of a consolidation warehouse on required capacity will be considered. 

Scale up. Once a proprietary process yields the desired biological, chemical, and physical properties, the challenge for the engineer or manufacturing professional is to scale up and design a process that preserves the finished product design specifications and is economically feasible. Moving from lab scale to production scale presents many technical problems. Technical solutions to the problem are often costly and can conflict with economical solutions. 

Using the stmcture of user, task and environment (UTE) provides the reader with a mechanism to better understand requirements embodied within the product design specification (PDS), and provides context for the interrelationship between elements (see Fig. 7.1). The optimum compromise wiU be defined within the PDS for handwear or footwear products in the UK context. 

In terms of PPE technology, there are considerable possibilities for extremity protection the capability offered by the technology will, however, impact its affordability. The constraint of cost and value for money is one issue that should be factored into any new product design specification. Aspects to be considered within this section include ... 

Informational Design Phase product design specifications, in which the needs of users are identified while considering different attributes functional, ergonomic, safety, reliability, modularity, aesthetic and legal, among others [11]. This information comes from users of medical equipment. The activities of this phase include the survey and description of the tasks and actions that reveal the conditions and activity execution manner by the user [34—36]. 

All this activity is aimed at producing products that use less in the way of materials and in turn let less material enter the solid-waste stream. Some designers, including myself, have habitually listed in product design specifications that specific environmental requirements should be met. 

Luzenac America offers a broad selection of talc products designed specifically for plastic applications. Talc is a white, crystalline, platy mineral. It Is the softest of all minerals, and in many applications, its shape imparts cost-effective and beneficial structural properties to the final product. Luzenac talcs are available in various particle size distributions and from a wide variety of Luzenac-owned ore sources. 

The placing in the product design cycle of process selection in the context of engineering for manufacture and assembly is illustrated in Figure 1.18. The selection of an appropriate set of processes for a product is very difficult to perform effectively without a sound Product Design Specification (PDS). A well-constructed PDS lists all the needs of the customers, end users and the business to be satisfied. It should be written and used by the Product Team and provide a reference point for any emerging design or prototype. Any conflict between customer needs and product functionality should be referred back to the PDS. 

There are clearly very significant differences between these products, in terms of stiffness, strength, and ductility. Each is formulated for a specific type of assembly. As noted above, the mechanical behavior is only one element to be considered in material choice. For a boat-builder, gap filling or sufficient viscosity to allow bonding onto vertical surfaces may be as or more important, while for an offshore flow line thermal properties may be critical. In addition to a range of standard commercial products, adhesive suppliers will therefore formulate special products designed specifically for an end user s requirements. 

According to a report issued by the Chinese National Commercial Information Center (CNCIC), the most popular brands of skin care products are provided in Table 2. Notice that the skin care products designed specifically for Asian skin such as Aupres by Shiseido are well received in China (c.f, Jones et al. (2005)).
