Introduction The MIJC: a step towards establishing a product design culture. The goal of this course is to give you the tools to develop an efficient design process regardless of the product being designed.

Definitions (1/3) Product : A term used to describe all goods, services, and knowledge sold.

Definitions (2/3) A Product Development Process is the entire set of activities required to bring a new product concept to a state of market readiness. PD is the organization and management of people and the information they develop in the evolution of a product.

The Life of a Product Identification of need Development of engineering requirements Design concept development Product design Manufacturing Assembly Distribution Installation Use Retirement, disassembly, reuse, and recycle.

Retirement, disassembly, reuse, and recycle.

Product Conceptual Design Design = Science + Art

FORM and FUNCTION The product FORM should reflect its FUNCTION FUNCTION = What the product is to do FORM = How the product is to do its FUNCTION

The product FORM should reflect its FUNCTION

FUNCTION = What the product is to do

FORM = How the product is to do its FUNCTION

FORM = Shape (geometry), Material, Connections, Energy and Material Flow, Operation Procedure (Information Transfer), etc…. Design is the process of mapping function to form. Design problems have many satisfactory solutions and no clear best solution

FORM = Shape (geometry), Material, Connections, Energy and Material Flow, Operation Procedure (Information Transfer), etc….

Design is the process of mapping function to form.

Design problems have many satisfactory solutions and no clear best solution

Two Fundamental “Rules’ of Design I. The Function Rule: Design requirements should be satisfied Independently…Hard to achieve! II. The Form Rule: The design must have the least possible information content.

I. The Function Rule:

Design requirements should be satisfied Independently…Hard to achieve!

II. The Form Rule:

The design must have the least possible information content.

Fundamental Rules Updated I. The Function Rule: Design requirements must be satisfied uniformly. II. The Form Rule: The design must have the shortest production path.

I. The Function Rule:

Design requirements must be satisfied uniformly.

II. The Form Rule:

The design must have the shortest production path.

The Golden Triangle Effectiveness of the design process is measured by: Product cost Product quality Time to market (TTM)

Effectiveness of the design process is measured by:

Product cost

Product quality

Time to market (TTM)

The Design Paradox The more you learn the less freedom you have to use what you know. CE relieves this difficulty.

Design Process Evolution Craftsmanship – one person could design and manufacture an entire product By the middle of the 20 th century: over-the-wall approach. From the late 1980s: concurrent engineering approach (CE).

From the late 1980s: concurrent engineering approach (CE).

The Over-The-Wall Design Method

Concurrent Engineering (CE) CE emphasizes the integration of cross-functional TEAMS to develop the product. The use of teams, including all the stakeholders, eliminates many of the problems with the over-the-wall method. Stakeholders = people who have a concern for the product.

Stakeholders = people who have a concern for the product.

Controllable Variables in CE

The CE Design Team A team may be defined as two or more persons engaged in a common goal, who are dependent on one another for results, and who have joint accountability for the outcomes. The PRIDE principle should be followed in any product development project – P urpose, R espect, I ndividuals, D iscussions, and E xcellence

Summary (1/2) Product design is a part of the product development process. PD must be centered on the CUSTOMER. The Japanese say: Listen to the VOC! Design is a process of function-to-form mapping.

Summary (2/2) Success at PD is measured by Cost, Quality, and TTM. Concurrent Engineering = early involvement of stakeholders CE suggests an integrated product and process design (IPPD) Early phases of design are the most critical to the design success.
