Rapid prototyping is an intensive process of collecting information on requirements and on the adequacy and functionality of fairly new product designs. Model prototyping is an important data resource during the different stages of product development. Model prototyping makes use of various kinds of rapid prototyping techniques to provide the right model types used for different testing procedures. Such techniques may require the use of requirements animation, incremental, and evolutionary prototyping.
1. Requirements Animation- is the method used mainly to demonstrate functionality in test cases that can be easily assessed by users. Software tools are used to produce representational prototype models that are built using animation packages as well as screen painters.
2. Incremental prototyping- enables the development of large prototype system models installed in phases in order to avoid delays between product specification and its final delivery into the consumer market. Once the customer and supplier have agreed on certain core features, the installation of a skeleton system is applied as soon as possible. Important requirements can be checked out as the model is being used, enabling changes to core features while in operation with extra and optional features can be added later.
3. Evolutionary prototyping- considered as the most integral form of prototyping. It acts as a compromise between production methods and with that of model prototyping. Employing this technique, a model prototype is initially constructed that is then evaluated as it evolves continually and becomes a highly improved end product. Many designers believe that more acceptable systems would result if evolutionary prototyping were interconnected with periods of requirements animation or rapid prototyping. Here the tools are the actual facilities resources where the final system will be implemented.
The use of different model prototyping techniques can help do away with the uncertainties about how well a final design may be able to fit into the end user's needs. The different model prototyping techniques help product designers make the necessary decisions by obtaining information from initial test users about the effective functionality of a certain product prototype.
Model prototyping can also be an effective aid in determining how effective and ideal the features and the overall design can be for proposed users. Model prototyping and the subsequent testing procedures can provide useful representation information that can reveal possible design flaws, effective features as well as useless functions that can either be corrected, enhanced or done away with on the next stages of product development.
Before a product is introduced to the public, the inventor has to draw up a plan and put it in paper. This is exactly what the Wright Brothers did when the first airplane was built and took off into the air.
More than a hundred years later, the airplane has evolved from being a propelled machine into one that is powered with jet engines. Today, there are planes that are used for private and commercial use but those that can travel more than four times the spend of sound are used for military purposes.
There were a lot of changes through the years that made this happen which occurred both in times of war and peace. In fact, the innovations made towards the end of the Second World War paved the way for the jet age.
This is done by reviewing the old equipment such as the V2 rockets and then reinventing it so that a plane can use the same principles in flight over greater distance and height. The aeronautical industry is not the only one that does this because other fields are doing the same thing, which is better known as prototyping.
Prototyping by definition simply means learning from things in the past such as an old design and improving on it. This will cost both time and money in order to perfect the system, which is the reason some car manufacturers only release, a new model every five years.
Some of the things designers and engineers will look at are flaws in the old model. This could be from customer complaints as well as reports from dealers in the field who received the owner's vehicle and needed a repair. The company may make recalls like what Ford has done over the past few years and the only way to prevent this from happening again is by correcting those mistakes.
When the people think that the errors have been corrected, it is time to test this by making one model and then seeing how well it performs through a racecourse. Sensors, cameras and the input of the test driver will be collected so this can be reviewed for analysis.
If everything goes well and the budget for the new model is reasonable, then the company can begin production. Marketing will just have to think about the name of the new car and the events to launch this, which will surely excite regular clients who have purchased a vehicle or two in the past.
