Mechanical Design Process implies that all the processes of conception, invention, visualization, calculation and refinement and specification of the details to form a final product. The term design is often used to describe an object’s aesthetic appearance with the specific reference to its form and the external appearance and function. The word is borrowed from the Latin ‘designare’, which implies to designate or to mark out.
The process generally begins with a requirement which is usually an idea and ends with drawings or computer representations and other details which will enable a product to be utilized. Engineering in Kenya has more articles.
Steps involved in the Mechanical Design Process
The first thing to be considered is the ability to recognize the iterative steps that are associated with the design. This incorporates all the processes that will be required to develop a product from a design specification from the consumers brief. From the brief, one should be able to develop a morphological design chart to aid the development of conceptual solutions.
Mechanical Design Process requires one to be able to participate in brainstorming activities while recognizing the scope of the technology that is available to the draftsman. The process of design begins with the recognition of need. This describes the idea or need a customer may have developed. It could be a new idea or an existing idea that needs to be re-engineered. This first process is also referred to as market brief.
Analysis, Synthesis and Optimization of the Mechanical Design Process
The next process is the definition of problem. This usually requires specifying requirements for the product. This would include the characteristics, inputs and out puts, characteristics, dimensions and their limitations of the quantities. Synthesis of the product is the next step in Mechanical Design Process. The idea developed is then synthesized. This is the process of producing a component via a series of reactions.
The component synthesized is then analyzed. This is done by application of engineering courses such as statistics and dynamics of materials, fluid flow and the heat transfer. Analysis and synthesis process virtually go hand in hand. This is because after synthesis (putting together of the component) then analysis must follow (resolving something into a constituent parts).
Analyzing the product helps in identifying any deficiencies in the product which would require repetition of the product or synthesis of the entire product. This process is then followed by optimization. Optimization involves repetitively refining the set of the usually criteria that are conflicting. The last process is the evaluation. It is at this stage where the product is checked whether it correlates to the consumer’s requirements.
Advancement in Mechanical Design Process
Nowadays, designers are compelled to consider a number of issues such as product liability and environmental friendliness. Others are product functionality and the performance of the artifacts. Developing successful designing processes is a complicated process which requires by compiling design knowledge and the information. There are two approaches required; one is through general building block library or the knowledge base for design problems or by storing the previous designs and using them to develop the new idea.
The recent computerized facilities have helped in developing designers to create three dimensions models. The designing has been a two dimension for a long time but with the recent technology; there are programs like computer aided design (CAD) that are very beneficial to the designer. Virtually, in every engineering sub-discipline and by many other engineering and architectural branches practice Mechanical Design Process.
