Question

In a which design approach, during the detailed design stage which of the following is undertaken?​

Answer 1

Explanation:

The detail design phase defines the complete specification of the geometry, materials, and tolerances of all the parts through the provision of detail drawings, assembly drawings, and general assembly drawings. It also includes the specification of all the bought-out parts complete with preferred suppliers and component designations. The result of this phase is the complete and precise physical description of all the parts in the product. These drawings can then be issued to the manufacturing function for precise manufacture and assembly.

The detail drawings require an index in order to be understood and coordinated. Along with the detail drawings, therefore, there should be a general parts list, which will act as a “map” and precisely instruct the manufacturing function to group components into assemblies and, further, assemblies into the full product. Figure 4.5 shows a portion of a typical parts list, which lists all the parts along with raw material sizes and specifications. It should be noted that this particular parts list shows elements of three subassemblies.

The detail design phase takes the concept design and applies it to the material components and, in effect, plans the manufacture and assembly of the product. During this process, the designers consider the selection of materials, manufacturing techniques, machine tools, and processes such as forging, injection molding, and casting. Further processes such as chromium plating and painting are added to the specification.

It must be emphasized here that every single component and process required to complete the product and which, therefore, adds cost to the product requires a detailed specification at this stage.

The detail design often relates to the product, but once the product has been defined precisely in terms of technical drawings, other manufacturing elements may be pursued such as specialist machine tools, jigs, and other specialist manufacturing equipment.

Answer 2

Concept design

Concept design approach, during the detailed design stage.

• The product's design must be finished at the detail design phase. The design team works to finish the specifications for the final product, its components, subassemblies, and manufacturing procedures. Iteration is a key component of detail design, as it is in all other stages of product development.
• Phase One of comprehensive design and engineering is called conceptual design, and the primary product of this phase is drawings. The goal of the conceptual phase is to commit ideas to paper, even if the drawings created are sometimes relatively simple concepts with little detail.
• Concept design is a stage of the design process, to put it simply. It is the stage of the development cycle that normally occurs between the specifications for the product and the detailed design. The typical placement within manufacturing is as follows: Conceptual design comes after requirements, followed by detailed design, prototyping, and manufacturing.
