You are working as a management engineer for a trailer company, which designs and builds an ultra$-$light trailer $($a trailer that can be towed by a regular auto, weighs under $1000$kgs$)$ for outdoor, trekking and camping activities. It is planned to include several key features in the trailer you are going to design. Especially, an equipment such as boat to facilitate water sports, at least double living space, other features that can handle two$-$three day camps at the outdoor locations $($i$.$e$.$ power units and AC$/$DC convertors, basin and water storage, WC and waste water storage, storage spaces$).$ You will lead a team composed of industrial designers, mechanical engineers, electrical$-$electronics engineers, software engineers and supervise the whole project.

Assume that, the top management team has decided that you develop a product, which can radically differentiate itself from the competitor products existing in the market and target young, active, innovative and environmentally conscious customers.

You see the visual displays of the three concepts presented to you by your design team as well as the Lance Trailer$$s Type $1475,$ which is the reference product in the market. $1475$ weighs about $1300$kgs$,$ however it can be towed by automobiles, which produce more than $160$ HPs $($More than half of the cars in the market produce less than this power$).$

Concept $1($boat$,$ double bed, cabinets, power is optional$)$

Concept $2($amphibian$,$ double bed, cabinets, power standard,solar installable$)$

Concept $3($retro look, double bed, cabinets,kitchen, stove, refrigerator, power standard, changable design outlook$)$

Reference concept Lance $1475($full equipped$-$AC$,$ WC$-$bathroom, kitchen, microwave, stove, refrigerator,TV$,$ double seats, table, closets and double bed$)1300$ kg

$1.$ Assume that the customer needs for your product have been collected from the potential users as above.

a$)$ Group, evaluate and prioritize customer needs. $(10$ points$).$

b$)$ Define three product specifications that match your clustered customer needs. Be sure that they are measurable engineering metrics $(10$ points$).$

c$)$ Chart concept selection matrix and calculate scores.

$2.$ Describe which of the above concepts are more modular, which are more integrated?
