A revised text that presents specific design methods within an overall strategy from concept to detail design
The fifth edition of Engineering Design Methods is an improved and updated version of this very successful, classic text on engineering product design. It provides an overview of design activities and processes, detailed descriptions and examples of how to use key design methods, and outlines design project strategies and management techniques. Written by a noted expert on the topic, the new edition contains an enriched variety of examples and case studies, and up to date material on design thinking and the development of design expertise.
This new edition opens with a compelling original case study of a revolutionary new city-car design by ex-Formula One designer Gordon Murray. The study illustrates the complete development of a novel design and brings to life the process of design, from concept through to prototype. The core of the book presents detailed instructions and examples for using design methods throughout the design process, ranging from identifying new product opportunities, through establishing functions and setting requirements, to generating, evaluating and improving alternative designs. This important book:
- Offers a revised and updated edition of an established, successful text on understanding the design process and using design methods
- Includes new material on design thinking and design ability and new examples of the use of design methods
- Presents clear, detailed and illustrated presentations of eight key design methods in engineering product design
Written for undergraduates and postgraduates across all fields of engineering and product design, the fifth edition of Engineering Design Methods offers an updated, substantial, and reliable text on product design and innovation.
Cover Title Page Copyright Page Contents Introduction Part 1 Design Fundamentals Chapter 1 The Activity of Design What Designers Say What Designers Do Communication of designs Evaluation of designs Generation of designs Exploration of designs Case Study Chapter 2 The Nature of Design Design Problems Ill-defined problems Problem Structures How Designers Problem-Solve Chapter 3 The Process of Design Descriptive Models Prescriptive Models Integrative Models Part 2 Design Practice Chapter 4 Design Procedures Systematic Procedures Design Methods Creative Methods Brainstorming Synectics Example: Forklift truck Enlarging the search space The creative process Rational Methods Chapter 5 Identifying Opportunities The User Scenarios Method Procedure Practice being a user of a product or service Observe users in action Question users about their experiences Create relevant user personas and scenarios Define the preliminary goal, context, constraints and criteria for a new product opportunity Summary Examples Example 1: Sewing machine Example 2: Digital radio Example 3: Oven aid Worked example: Message recorder Chapter 6 Clarifying Objectives The Objectives Tree Method Procedure Prepare a list of design objectives Order the list into sets of higher-level and lower-level objectives Draw a diagrammatic tree of objectives, showing hierarchical relationships and interconnections Summary Examples Example 1: City transport system Example 2: Impulse-loading test rig Example 3: Automatic teamaker Example 4: Surgical shoe Worked example: High-pressure pump Chapter 7 Establishing Functions The Function Analysis Method Procedure Express the overall function for the design in terms of the conversion of inputs into outputs Break down the overall function into a set of essential sub-functions Draw a block diagram showing the interactions between sub-functions Draw the system boundary Search for appropriate components for performing the subfunctions and their interactions Summary Examples Example 1: A feed delivery system Example 2: Packing carpet squares Example 3: Inkjet printer Example 4: Fuel gauge Worked example: Washing machine Chapter 8 Setting Requirements The Performance Specification Method Procedure Consider the different levels of generality of solution which might be applicable Determine the level of generality at which to operate Identify the required performance attributes State succinct and precise performance requirements for each attribute Summary Examples Example 1: Onehanded mixing tap Example 2: Seat suspension unit Example 3: Electric toothbrush Example 4: Pill dispenser Worked example: Portable fax machine Chapter 9 Determining Characteristics The Quality Function Deployment Method Procedure Identify customer requirements in terms of product attributes Determine the relative importance of the attributes Draw a matrix of product attributes against engineering characteristics Identify the relationships between engineering characteristics and product attributes Identify any relevant interactions between engineering characteristics Evaluate the attributes of competing products Set target figures to be achieved for the engineering characteristics Summary Examples Example 1: Bicycle splashguard Example 2: Cordless drill Example 3: Car door Worked example: Fan heater Chapter 10 Generating Alternatives The Morphological Chart Method Procedure List the features or functions that are essential to the product For each feature or function list the means by which it might be achieved Draw up a chart containing all the possible sub-solutions Identify feasible combinations of sub-solutions Summary Examples Example 1: Potato harvesting machine Example 2: Welding positioner Example 3: Plant pot Example 4: Field maintenance machine Worked example: Forklift truck Chapter 11 Evaluating Alternatives The Weighted Objectives Method Procedure List the design objectives Rank-order the list of objectives Assign relative weightings to the objectives Establish performance parameters or utility scores for each of the objectives Calculate and compare the relative utility values of the alternative designs Summary Examples Example 1: Van rain shield Example 2: Bicycle splashguard Example 3: Pill dispenser Example 4: Emergency toilet Worked example: Reusable syringe Chapter 12 Improving Details The Value Engineering Method Procedure List the separate components of the product, and identify the function served by each component Determine the values of the identified functions Determine the costs of the components Search for ways of reducing cost without reducing value, or of adding value without adding cost Evaluate alternatives and select improvements Summary Examples Example 1: Tubular heater Example 2: Ceiling diffuser Example 3: Piston Example 4: Ceiling fan Worked Example: Handtorch Chapter 13 Design Strategies What is a Design Strategy? Strategy Styles Strategy Analogies Strategy Frameworks Strategy Control Keep your objectives clear Keep your strategy under review Involve other people Keep separate files for different aspects Learning to Design Developing Expertise Part 3 Design Thinking Chapter 14 Design and Innovation Product Planning Design for the Market Technology Push and Market Pull Systems Design References and Sources Index EULA
