Abstract [en]

This report is the result of a Thesis project at the Master Programme in Industrial Design Engineering at Luleå University of Technology (LTU). The project took place between Januari and August 2012 and the goal is to develop a new kind of hand held pump for people with rheumatism. The project is initiated by Fredrik Martinsson, a client based in Mölndal, but the work is done at LTU. The purpose is to develop a new user friendly product to make it easier for people with lowered functionality in their hands to inflate car- and bicycle tires. Existing pumps are based on outdated technology and contain a lot of cumbersome steps during use. The client’s requirements focus on a user friendly product and quick usage which excludes the possibility of a completely manual pump. To meet the specific demands the development work aims to design a portable product that is easy to carry with a propulsion method fast enough to inflate a tire in a matter of seconds. Limitations during the project is an additional market analysis, regarding market potential, other than the one received from the client. It will therefore be assumed that there is an existing need for the product and that the primary users are people with rheumatism and also people who seek a user friendly and fast pump. The overall goal is a fully functional prototype. Package design and marketing material will not be considered. The project started out with conventional methods for project management and a project plan, time plan and included acitivies were discussed with the client. A product development process consisting of four different phases with dedicated deliverables was created. The first phase consists of convergent data collection with user studies, interviews and benchmarking. A problem statement and requirements list were made and lay the foundation for the second creative ideation phase. The quantitative amount of ideas generated were evaluated with numerous methods and a set of concepts were created for further development. The concepts were then refined with sketches, mock-ups and computer models in the third phase to narrow the solution space down to one final concept. Before the fourth and last phase, concepts were evaluated once more and one final direction was chosen for embodiment design. The winning concept was concretized to a finished product with a fully functioning prototype, manufacturing drawings, methods and authentic computer renderings. The result is a new-to-the-world portable pump based on usage in a standing position. This reduces the strain on finger joints, wrist as well as hips, back and knees. The product folds up to a small compact cylinder for transportation which meets the dimensional requirements and is then unfolded with a spring-loaded telescope function before use. It inflates an empty bicycle tire in about five seconds thanks to the built in C02 cartridge. The nozzle is pressed against the tire’s vault with an ergonomic grip, similar to a crutch, which then opens a small valve that activates the C02 cartridge. The pump refills through a separate refill station loaded with regular Sodastream bottles which can be bought at any supermarket.
