New Good

In the olden days the motto was "I designed it; you build it!" Design engineers worked alone and Designs were then thrown over the wall leaving manufacturing people with the dilemma how to manufacture. Often this delayed both the product launch and the time to ramp up to full production. In the new good days manufacturability can be assured by developing products in multi-functional teams with early and active participation from Manufacturing, Marketing (and even customers), Finance, Industrial Designers, Quality, Service, Purchasing, Vendors and factory works. The need for a holistic approach between design and manufacturing is required. The two concepts Design for Manufacturing & Design for Assembly has become the need of the hour. The heart of any design for manufacturing system is a group of design principles or guidelines that are structured to help the designer reduce the cost and difficulty of manufacturing an item.Realisation of Cryogenic thrust chamber includes various manufacturing processes like Forming, Welding, Machining and Brazing. During initial stages of Thrust chamber realisation problems like Forming of 1.7m long nozzle divergent from thin sheets, welding of various intricate geometries & assembly of critical parts were observed. Subsequently these problems were studied based on the holistic approach of Design for manufacturing & design for assembly. Improvements based on the above study were considered in design & critical processes modifications resulting in successful and timely realization of the thrust chamber.

Hypothetical Scenario

The paper presents a tool for selecting appropriate Design for Manufacturing and Design for Assembly rules during product design while considering Design for Disassembly rules and end-of-life recovery conditions. This tool exposes the relations between the various types of design rules and end-of-life recovery parameters. Four different relationship types are developed in this research: recovery conditions and recovery options relationship, Design for Disassembly rules and recovery options relationship, Design for Disassembly rules and recovery conditions relationship, Design for Disassembly rules, and Design for Manufacturing and Design for Assembly rules relationship. The purpose of this research is to build these relations and transform these relationships into a database. The database serves as tool from which design rules can be retrieved by running queries. In addition to design rule retrieval, the tool also shows the relationships with various design rules, recovery options, and recovery conditions. This provides designers with information as to which rules are in conflict and which are complementary for the specific situation under consideration. To illustrate this tool, it is applied to motor-drive assembly and thermal gun sight, which are already design products. Additionally the application of the tool is demonstrated using a hypothetical scenario which involves products like coffee cup, cell phone and stapler.
