1 3.6 Implementation Philadelphia University, Jordan

2 Preview In the previous sequence, Analysis and Design was discussed. In this sequence, Implementation will be presented.

3 Seven Design Steps 1. Define the Problem 2. Gather Information 3. Propose Solutions 4. Study the Solutions 5. Analyze and Design the chosen solution 6. Implement the Design 7. Evaluate Performance

4 Implementation Construction and manufacturing of the solution Work with manufacturing engineers from the beginning Supply working drawings, documentation, and plans for manufacturing Specify manufacturing tools and processing to be used Build Prototype

5 Implement the Concept At this stage in the design process, A clear understanding of the problem has been formulated The design concept has been chosen Drawings, schematics, flow codes, and list of materials have been developed. So, next step is to implement the design concept

6 Implement the Concept Many problems might arise when trying to implement a design concept This is the normal The key is Not to be discouraged Learn from mistakes Have fun The result: a fully operational system that is ready to be tested.

7 Implement the Design The hardware should be constructed and tested to verify the design concept and analysis Transform the design from paper to physical reality Two main techniques are available: Quick-and-Dirty Prototype

8 Quick-and-Dirty Construction from plastics, wood,.. etc. Quick and easy to build Relatively cheap Used to check clearance, assembly technique, manufacturing considerations, and appearance.

9 Quick-and-Dirty: Bread Boards

10 Prototype A prototype can be defined as a model that represents a product or system. This model is usually used for functionality testing and product visualization. Prototyping is essential in the development of products and all industrial nations have prototyping centers. In fact, prototyping plays a major role in the advancement of technology.

11 Prototype In the prototyping development cycle, initial prototypes are built, tested, and then reworked as necessary until an acceptable prototype is finally achieved from which the complete system or product can be developed. Three types of prototyping Rapid Prototyping Virtual Prototyping PCB Prototyping

12 Rapid Prototyping Produces physical prototypes in short time (within hours or days rather than weeks). These prototypes are frequently used to quickly test the product's look, dimension, and feel. Rapid prototyping usually can result in plastic objects.

13 Virtual Prototyping Computer-based without the option of a physical part or object. It uses virtual reality to create product prototypes and test their properties. It provides a virtual 3-D prototype that can be manipulated from all views and angles. The computer program can then test many aspects of the product such as vibration, forces, materials and weight.

14 PCB Prototyping The production of a functional Printed Circuit Board (PCB). The product can then be tested for its functionality and reliability

15 CAD / CAM Computer-Aided Design (CAD) A designer starts with an idea of a new product and uses the CAD software to create a preliminary design. The preliminary design can also be analyzed for functionality as the design is being created. Modifications and reanalyzes of the computer model can be done Computer-Aided manufacturing (CAM) Used to drive appropriate machinery to physically create the part. The entire design cycle is shortened Engineers can go from design to prototype in a matter of days, instead of weeks or months

16 CAD / CAM

17 Prototypes

18 Prototyping Advantages Provides the proof of concept Shows the users how the final system would look like Reduces development costs Increases system development speed and quality Assists to identify any problems with early designs Refines the potential risks associated with the product delivery

19 Additional tasks Assess progress and discuss quality, safety, and technical concerns Integrate changes from design reviews Verify the requirements, connections, and interfaces Coordinate with staff to ensure proper fabrication and installation

20 Conclusion The 6 th step in the design process, Implementation, was presented The implementation can be a quick-and-dirty or a prototype Prototypes are divided into three types Rapid Virtual PCB
