Integral system-level design is often preferred when weight, shape, size & cost constraints affect and undermine the product’s performance. Hence, the functional implementation is achieved by one or very few modules where components perform multiple functions. Integral product architecture is where the functions of the engineering product are carried out by a combination of parts that are not organized in a structured manner. Modular vs integral product architecture Integral Engineering products with modular architecture are more common than integral designs. These are then interfaced together to form the complete product to perform its complete function. These modules are treated as individual components and have well-defined electrical or mechanical interfaces. In modular design, the overall product purpose or system-level function is subdivided into smaller single functions or individual operations and allocated to single parts or sub-assemblies called modules. Product architecture can fall into two categories or styles. Product architecture is vital to any product development as it would impact the product evaluation and the cost of the product. System-level design is defined by how each subcomponent or modules interacts with each other at a product level and the function of each subcomponent. DSLR architecture (credit: google images) Product architecture could start with very simple block diagrams, as shown in figure 4, or could be well thought out as an ongoing family of products. Physical elements are defined and arranged to satisfy the overall product requirement specification and are usually called modules. Product architecture, also referred to as System-level design, is, outlining and allocating physical components or entities to the function of a product. Embodiment designĮmbodiment design phase activities can be divided into three sections or phases (figure 3). So, at the embodiment stage of new product development, an abstract design concept will get moulded into a system or product that works and can be manufactured within the allocated unit cost. It depends on what type of product development the company is pursuing.Įmbodiment design is a complex process as many design activities must be simultaneously performed, some of the design activities need to be repeated several times with changing data, and any changes in one section will influence another section of the design.Įvery engineering product design is different and adds this to the above challenges, which is precisely why it’s very difficult to have strict set-out plans for the embodiment design phase. The output from the Concept design might vary from simple block diagrams (figure 2) to very early prototype concepts. Defined DSLR concept design (credit: google images) Concept design followed by Embodiment design and detailed design is more suitable for an engineering product design hence this article uses these terms, although there are various product design process models. Embodiment design was coined by Pahl and Beitz (2006) and adopted mostly by modern European engineering product design managers. In some literature sections, this phase is also referred to as preliminary or system-level design. The embodiment product design phase of an engineering product design follows the concept design phase, where various concepts are generated and evaluated to produce a single final concept. What is Embodiment design?Įmbodiment design is one of the main stages of the product design process in which the main engineering product design concept is developed as per the product design specification (PDS) and economic criteria to a stage where subsequent detailed design can lead directly into production. During the Embodiment design phase, the main concept is developed to a stage where detailed design can lead directly into production.
