Summary This report analyzes the needs to the products, but also the technical aspects of a hair dryer and a Davit. The technical aspects include the connections, transmissions and formats. The goal is to own a Davit. The chapters in this report in the following aspects:

-          The needs and problems that come with the products come look.-          The functions are handled and the product is examined.-          The products are very technical and therefore analysed the material properties,

connections and production techniques.-          In the last chapter, the package of demands and wishes.

 The conclusion is that the hair dryer solves the problems of the target group. The hair dryer solves that by meeting the requirements and if possible the wishes. The Davit solves the problem of a sports owner who does not want to lift the water independently in zijn/haar lifeboat. Through the package of requirements drawn up solves the problem.     

Glossary A davit Davit is a hoist with which a lifeboat of a ship or yacht can be hoisted in the water. Exploded view a technical drawing in which a part is signed as if it is exploding. A mechanical device that works with moving parts. At a closed shape closed shape construction has only the shape made sure that the components

are connected. This makes the material closed material ensure that the parts are linked with one another. Force closed there is much force on the component which means that there is no connection is

required (e.g. a table). STAINLESS STEEL This abbreviation stands for stainless steel, also known as stainless

steel.

Introduction The first part of the report deals with the importance of the hair dryer and that peoplewith long hair who have just showered can dry their hair in minutes. The hair dryer will fix this problem and make sure that people with (often long) wet hair no longer need long to dry off or wait until it is dry. The second part of the report concerns the importance when the yacht owners is that they the dinghy from their hunt lay in the water without much physical strength.The Davit will fix this problem by means of a hoist and will also minimize visible on the boat. The report deals with the Davit how the boat in and out of the water can be hoisted and the use for the yacht owner is as simple as possible.

2.3 Davit Connections and transmissions Transmissions 

1. Button. The physical energy of the person it serves is converted into an electrical signal because the button is pressed. The electrical signal goes to the electric motor.

2. Electric motor, the electric motor converts electrical energy to a circular motion.3. Scharnieren/assen (mechanical). The hinges ensure that the Davit the forces over can

put in a horizontal movement.4. Pulley for cable (mechanical). The pulley ensures that the cable can sue its way with the

minimum of resistance. The mechanical force is converted to mechanical power in a different direction.

5. Cables (pull). The cables put a the rotating power of the electric motor to linear in a pulling force.

 Connections 

1. Steel construction (material closed). The frame is a very firm connection of steel frame pieces that have been confirmed by a jointed to each other.

2. Ground fixing (closed form). Because the floor plate with bolts (and nuts) is confirmed in the floor of the boat cannot move relative to the boat.

3. Carbine (closed form). The carbine confirmed the cable to the boat by means of a steel ring that is strong enough to show the power of the boat. The carbine is loose to get through the click system so that the boat can sail away without the carbine still stuck.

4. Electric motor (closed form). Because the electric motor in the solid form is cast and this material is closed with bolts is the electric motor well stuck in each other.

5. Cable (power closed). The shape of the copper cable can not get out. At the end of the cable is the cable clamped (also closed).

2.6 Davit Set of requirements Set of requirements 

-          The boat has to be within five minutes in the water and usable-          The Davit from outside the boat does not show-          Easy operation, the customer must within 30 minutes, understand how the system can

be operated-          Dangerous parts must be shielded (Safety)-          The Davit should be installed within seven days-          Weight, up to 10% of the weight of the hunt

 Production The production varies with the type of Davits Davits. At unique yachts the Davit be custom made and there will be no mass production possible. At universal boten/jachten is mass production possible.

3 Conclusion This report was about two products with a problem for which we have devised a solution for in the form of a product. Hair dryer The aim of this project was to provide a solution in the form of a product to think for a problem where people want to have their hair dried quickly with wet hair.The set of requirements is largely a conclusion of the hair dryer. It contains the requirements that the hair dryer a functioning product.The most important requirements:

-          Within 2 minutes dry hair-          Up to 20 euro-          Easy to operate

As one of the requirements is not met will be the final product are not suitable and not successful. Davit   The problem is with the Davit is that yacht owners their dinghy in the water like to get through a system without (many) have to use physical force.The set of requirements is largely a conclusion that the Davit to a perfect working product.The most important requirements:

-          It must be the boat in the water move within 5 minutes-          Weight, up to 10% of the weight of the hunt-          The Davit should (almost) does not show from outside the hunting

The above requirements of the Davit Davit will make a perfectly functioning product.
