Konceptframtagning av maskinstativ för användning i nyttofordon : Design för möjliggörande av ergonomisk och enkel maskinanvändning / Concept development of machine stands for use in commercial vehicles : Design to enable ergonomic and easy machine operationAgardson, Agnes January 2023 (has links)
This Bachelor of Science thesis has been carried out during the spring of 2023 as a part of thecourse Degree Project for Bachelor of Science in Innovation and Design Engineering atKarlstad University. The degree project comprises 22,5 credits and the responsible student isAgnes Agardson with Johan Strandberg as supervisor and Leo De Vin as examiner. The project is performed in collaboration with the consulting company Rejlers on behalf ofone of their clients. In earlier stages of this cooperation, a machine has been developed andthis project is about further development within that same area. The purpose of this thesiswork is to create a solution on how to implement this machine in a commercial vehicle andadapt it to the user's needs and wishes and then perform a product development process withthe goal of developing a proposal solution that is presented with sketches, a prototype and CAD models. The main parts of the process has been divided into phases, a start-up, exploring, define,develop, deliver and a final phase that include a summary of the deliver phase, a writtenthesis, a final presentation and an exhibition. Some elements that were important in thisproject under these headings were, among other things, project plan, feasibility study, problemformulation, requirement specification, idea generation, concept selection, conceptdevelopment and construction. The process resulted in a concept proposal of a machine stand that is presented primarily via aCAD model but also with the help of sketches and a simple prototype. This concept proposalsolves the project’s main problem formulation and meets all predetermined requirements. Thesolution involves a foundation made of bent stainless steel sheet that is attached to the floor ofthe cargo compartment of a van. In this foundation, rails can be attached at different heights toadapt to the user’s height and position of the product, in turn a plate is attached to the rails, towhich the machine is attached. A locking function prevents the machine from moving wheninside the car and also allows the solution to be pulled out in several positions, a user modewhere the machine is only pulled out enough to enable use and a so-called service modewhere the machine is pulled out to the maximum to enable maintenance.
