Op weg naar een ontdekpad : het ontwerp van een voorziening voor veilig oversteken

Kemper, E.M. (2010) Op weg naar een ontdekpad : het ontwerp van een voorziening voor veilig oversteken.

Abstract:Cosmos, the observatory in Lattrop is expanding through the development of two “ontdekpaden” (literally discovery paths). These paths are meant to educate pupils of elementary school on different aspects of nature in an active way. One of these paths is located on the other side of a busy road. In order to get the target group safely across the road a crossing has been designed. This crossing makes use of the space beneath the bridge across the Dinkel, a river that is flowing by the observatory. Several analyses have been executed. Firstly a surrounding analysis has been performed to gain insight in the surroundings and the possibilities thereof. Thereafter the market has been analyzed. This analysis focused on other water playground facilities en on education on nature. To gain knowledge on the target group, lastly a target group analysis has been executed. These analyses have provided a basic knowledge, which will prove its use during the design phases. On the basis of the analyses and conversations with the employer a list of demands has been developed, which consists of demands which the crossing has to satisfy and wishes which the device could also fulfill. From the list of demands can be concluded that safety and maintenance are more important than education and amusement. Subsequently, ideas have been generated and tested against the demands. The ideas fulfill most demands, though they deviate on four demands. These demands are summarized in two characteristics. A plot was made to visualize which ideas posses the characteristics to which degree. Three ideas posses both characteristics and of these ideas the feasibility, advantages and disadvantages are explored. The gutter idea is combined with the idea to decorate the downside of the bridge. The advantage of this idea is that the children can walk upright under the bridge. The disadvantage is that this idea does not encourage the children to be active. The other two ideas are both more active, which is more suitable for the crossing. These ideas however have the disadvantage that it is not certain whether the children will prefer the crossing to simply crossing the road. Eventually it is decided to build a raft, since this will enable children to directly experience the flow of water. The idea to build a bridge underneath the bridge lacks this and is therefore dismissed. Thereafter the design is further elaborated on. A drive has been designed, which makes it possible for each user to be active. Furthermore it has been listed what should be altered in the surroundings, in order for the raft to work and be interesting for the users. A lot of attention has been paid to the safety of the raft. During normal use it is not possible for the children to fall in the water. Subsequently it has been examined what materials are most appropriate for the construction of the crossing en what would be suitable dimensions for the different elements of the raft. This has been mostly determined on the basis of what is being used in similar situations en the dimensions of the children. A model of the river, the bank and the crossing has been made to clarify what exactly is going to be build. Moreover the functioning of the crossing can be partly demonstrated by the model. During the manufacture of the model some useful insights have been gained, resulting in among others an altered height of the rail.Lasty there has been looked back upon the total design process and after that conclusions have been drawn and recommendations have been made.
