Utveckling av en produkt som förenklar koppling av släp / Development of a product that simplifies coupling of trailers

Mahmood, Furqan January 2015 (has links)
This thesis was conducted at SverigeGrepen in Vänge-Körlinge, Uppsala, Sweden.SverigeGrepen is a family business that develops and manufactures a few different parts of different kinds of products. My task is to come up with a good idea that facilitates the coupling of trailers, i.e. from an idea to a fully functioning prototype. The product is intended for use by all customers for all kinds of trailers. The actual goal of the work is to develop a full prototype that you can install and use in the easiest way possible, a prototype that follows the specifications. To understand the structural design of a trailer, different parts of it were studied, plus that the different user requirements specifications were specified, even the coupling methods that are already in the market were studied and understood.After being done with the study, started the ideas and concept generating. Different ideas of good methods someone can use to back up a car to a trailer and connect it, or in reverse, to move the trailer to the car instead, and the total were seven different concepts. The method used to develop concepts were particularly brainstorming. Then to go ahead with one of the developed concepts and determine the one that went on for prototyping, a concept selection matrix were used. Where the requirements were the specifications determined in the study.The result became drawing documents of a product that meets the specification requirement and purpose of the product. The drawing documents were submitted to one of SverigeGrepens companies called ‘KP welding and forging’, but the prototype was not completed within the framework of the thesis.

Den juridiska statusen för 3D-modeller som bygghandlingar / The legal status and impact on 3D-models as construction documents

Aasa, Emma, Rosell, Michaela January 2023 (has links)
Introduction – This thesis in Building Engineering at Jönköping University, in collaboration with Tyréns Sweden AB, examines the issues surrounding 3D models as construction documents from a legal perspective and investigates how digitization affects stakeholders in the construction industry. The goal of the study is to explore a relevant and interesting research area in order to contribute to knowledge development and the advancement of new theories or methods in the field. Method – The study will employ qualitative research, including primary data collection through interviews, to address the research questions posed in the report. The authors have chosen this method to achieve a comprehensive understanding of the respondents' perspectives and identify important themes and patterns. The interviews were conducted with participants from various sectors of the construction industry to obtain a broader picture of the subject. Results – The study revealed that there are certain legal barriers to the use of 3D models as drawing documentation. These barriers are related to a lack of knowledge and uncertainty in handling the models. This includes issues of copyright, liability, and evidential value. There is a need to update current regulations to facilitate the management of digital models. Analysis – The analysis of the results clarifies that industry standards and clearer guidelines would prevent uncertainties and address knowledge gaps in the use of BIM and 3D models. An industry standard could have facilitated a smoother transition to a more digitized construction industry. There is also a need for education in the field for professionals and decision-making stakeholders. Discussion – The discussion focuses on possible solutions to the identified problems, such as the development of standards and guidelines, education, and regulatory updates. There is also a need to raise awareness about the legal aspects of using 3D models in the construction industry, as the uncertainty regarding their legal status is high. Legally, it is possible to use 3D models as contractual documents, but the study shows that concerns about the legal aspects are a reason for the weak implementation. Keywords – 3D model, 3D design, BIM, Building Information Modeling, construction documents, contractual law, and copyright. / Introduktion – Detta examensarbete inom Byggnadsteknik vid Jönköpings Tekniska högskola i samarbete med Tyréns Sverige AB undersöker problematiken med 3D-modeller (tredimensionell modell) som bygghandlingar ur ett juridiskt perspektiv och undersöker hur digitaliseringen påverkar aktörer inom konstruktion. Studiens mål är att undersöka ett relevant och intressant forskningsområde för att bidra till kunskapsutveckling och utveckling av nya teorier eller metoder inom området. Metod – Studien kommer att använda kvalitativ forskning som inkluderar primärdatainsamling genom intervjuer för att besvara frågeställningarna i rapporten. Författarna har valt denna metod för att uppnå en omfattande förståelse av respondenternas perspektiv och identifiera viktiga teman och mönster. Intervjuerna genomfördes med respondenter från olika delar av byggbranschen för att få en bredare bild av ämnet. Resultat – Studien visade att det fanns vissa juridiska hinder för användningen av 3D-modeller som ritningsunderlag. Dessa hinder kopplas till bristande kunskap och osäkerhet i hantering av modellerna. Detta inkluderar frågor om upphovsrätt, ansvar och bevisvärde. Det finns ett behov att uppdatera dagens regelverk för att lättare hantera digitala modeller. Analys – I analys av resultatet klargörs det att en branschstandard och tydligare riktlinjer skulle förebygga osäkerheterna och förebygga kunskapsluckor för användandet av BIM och 3D-modeller. En branschstandard hade kunnat leda till en säkrare övergång till en mer digitaliserad byggbransch. Det finns också ett behov av utbildning inom området för yrkesverksamma och beslutsfattande aktörer. Diskussion – Diskussionen fokuserar på möjliga lösningar på de identifierade problemen, så som utveckling av standarder och riktlinjer, utbildning och uppdatering av regelverk. Det finns också ett behov av att öka medvetenheten om de juridiska aspekterna av användningen av 3D-modeller inom byggbranschen då osäkerheten av den juridiska statusen är hög. Juridiskt sett går det att använda sig av 3D- modeller som kontraktshandling, men studien visar att oron för det juridiska är en anledning till den svaga implementeringen. Nyckelord – 3D-modell, 3D-projektering, BIM, Building Information Modeling,, bygghandling, kontraktsha juridik och upphovsrätt
