Design och konstruktionsförbättringar

Sammanfattning

This thesis will describe the redesign of the manure fork SverigeGrepen. The product

is available for purchase in Scandinavia and and parts of the rest of Europe.

The product is available in stores but the companys goal is to start distribute it over

the internet. A problem today with a purchase over the internet is that the costumer

has to pay a high shipping-fee due to the products unique form. The long handle

contributes to the high shipping-fee which makes it hard to attract costumers to

purchase the product online. Deficiencies have been found at the manure forks basket

and needs to be examined. These problems need to be checked out so that

SverigeGrepen can become an even more compatitive product.

To obtain a solid theoretical ground a literature was made about the concerned

subjects.

The project proceeded with the gathering of information about the product, by

communications with the contact at the company and usage of the manure fork in it´s

real enviroment to locate complications with the design. Some temporary souloutions

have been tested but would in the long run be in need of new souloutions.

Based on similar products and the existing soloutions some new consepts were

introduced. The best concepts were mdeled in CAD and modified by some input

from the company and a plastic worker. Images of the CAD model and a real life-size

prototype printed in a 3D-printer were used as support during the discussions.

The outcome of the project is that design documents of an easy to use souloution to

assemble/dissmantle the manure forks shafthalves whitch minimizes the packaging

volume and thereby reduces the shipping costs, were made. Designpropositions were

produced to eliminate deficiencies located at parts of the basket in the beginning of

the project.
