Testing against design specification
4.1- To keep costs down, the materials used must be sourced locally and the
methods of production must be cheap. Never the less, this should not affect the
high quality of the product.
4.2- The packaging must be as minimal as possible, as this will reduce the cost
for both the manufacturer and user.
4.3- The price must not exceed a maximum of £200, in order for there to be a
competitive market price. Existing related products cost between £135-£210
with resistance bands between £15-£65. The minimum cost for my product
should be £60.
4.4- To keep costs low there must not be any pre-manufactured components to
my product. As in most cases these would be more expensive than manufacturing
components for the manufacturer themselves, as the manufacturer of the
component would need to make some profit.
5.1- The manufacturing process must be cost efficient as possible without
sacrificing quality.
5.2- The machinery used in the process must be constantly maintained and that
all workshop guidelines are kept to, to prevent any disasters.
5.3- There must be no pollutants given off by the machines, this is to make sure
that the environment is not harmed during the manufacturing process.
5.4- Although I will only be making a prototype concept of my design, in order to
make it profitable it must have options for mass manufacturing, whilst
maintaining its uniqueness
.6.1- The materials used must be of a high quality. However, not be excessively
expensive.
6.2- The materials must be strong and durable as the product life-spand should
be a minimum of 5 years if well maintained.
6.3- The materials shouldn’t be too heavy (Anything in excess of 30kg is too
heavy) so that it can be easily transported, disassembled and assembled by one
person. Also for safety reasons.
6.4- The materials should come from a sustainable source, so that it is
environmentally friendly and doesn’t involve a lot of harmful processes to
produce.
6.5- The materials must be water resistant and rust resistant so that the product
can be used in any environment without corroding. this will add to the life-spand
of the product.
6.6- Any coatings or paints onto the materials must be non-hazardous to both the
work environment and the natural environment as it would harm workers, animals
and plants.
Key
Product meets design specification
Product partially meets design specification
Product does not meet design specification
4.1- All materials I used for the prototype are sourced locally (UK) and I used machines in a
school workshop so it was cheap to make but the quality was as high as it could be in a school
environment. I did quality control checks at each stage.
4.2- (Marketing page) The packaging of the jackal trainer will be made to fit all parts in one
box, with additional space for Styrofoam to protect the parts during transportation stage.
4.3- All materials used were low of cost and if I were to retail the jackal trainer, I would retail it
at no more than £75.
4.4- There are some pre-manufactured components in the prototype design and in real
production there will be pre manufactured components as well. This is because it was not
possible to make the components I wanted in the workshop and also in real production it
would probably cost more to make ourselves than import.
5.1- The materials were low of cost and so to were the machines to use. The quality was at its
peak throughout as I did quality control check at each stage.
5.2- The machines were well maintained by the technician, and checked daily.
5.3- There were no pollutants given off during the making of my prototype. I used wood
materials throughout.
5.4- In order to mass produce the jackal trainer, I would have to use ABS plastic or
polypropylene and use blow moulding.
6.1- The plywood I used was smooth and had no incursions.
6.2- Plywood is a strong and durable material, especially after I added weather proof pain after
making.
6.3- The fully assembled jackal trainer weighs around 13kg, it is top heavy with the panels,
however doesn’t breach the weight limit set.
6.4- I used plywood for the prototype and that obviously comes from trees which can be
replanted. Therefore, the materials are sustainable.
6.5- I applied weather resistant paint finish to the plywood, so it will be able to withstand
outdoor conditions.
6.6- I used non-hazardous paint
Evaluation
My prototype of the jackal trainer meets the majority of the design specification I set early on
in the designing process. It fell short due to stuff I couldn’t control, such as the heigh limits a s
the aim is to get the user into a low body position. The one spec I didn’t meet was the pre-
manufactured components because it wasn’t possible to make them in a workshop. Overall, I
feel as though I have done a good job to meet all standards set and there is room for
modifications to the prototype to perhaps improve on the points it did not meet.
