The document discusses the process of rapid prototyping in engineering design, emphasizing its role in evaluating, modifying, and finalizing product designs. It highlights the importance of testing prototypes for functionality and design viability, and how early design modifications can reduce costs. Additionally, it addresses engineering design as a method for problem solving, incorporating planning, scheduling, and supply chain management.

3. Prototype
A prototype is an original model, form or an instance that serves as a
basis for other processes. In software technology, the term prototype is
a working example through which a new model or a new version of an
existing product can be derived.
In an engineering product design context, a prototype is a preliminary
version of the end-product and used to evaluate the design, test the
technology or analyse the working principle which in turn provides
product specification for a real working system.

4. Rapid prototyping
• Rapid prototype or rapid prototyping is a relatively new term and in
its simplest form, the process of creating prototypes quickly to
visually and functionally evaluate an engineering product design.

5. Testing a prototype / developed design is a very important part of the
design and manufacturing process. Testing and evaluation, simply
confirms that the product will work as it is supposed to, or if it needs
refinement.
In general, testing a prototype allows the designer and client to assess
the viability of a design. Will it be successful as a commercial product?
Testing also helps identify potential faults, which in turn allows the
designer to make improvements.

6. Design modifications
A design change is the
modification conducted to the
product. It can happen at any
stage in the product
development process. The design
changes that happen early in the
design process are less expensive
when compared to those that
take place after it is introduced
into full-scale production.

7. The building design process
resolves client requirements
into a set of instructions for
the construction of a building
that satisfies those
requirements. It is generally an
iterative process in which the
design becomes more detailed
and more 'fixed' as the project
progresses.

8. A functional cost analysis is a method
that can be applied to examine the
component costs of a product in
relation to the value as perceived by
the customer. The outcome of the
analysis is to improve the value of
the product while maintaining costs
and/or reduce the costs of the
product without reducing value.

9. Engineering the design
Engineering design is the method that engineers use to identify and
solve problems. It has been described and mapped out in many ways,
but all descriptions include some common attributes: Engineering
design is a process. This powerful approach to problem solving is
flexible enough to work in almost any situation.
