Låsförband mellan dörr och karmPersson, Stina, Pihlblad, Johan January 2023 (has links)
This bachelor’s degree project that includes 15 credits at Mälardalens University has been carried out at 50% for 20 weeks, spring semester 2023.The locking principle between door and frame has for a long time been unchanged. The report describes the workflow during the project where the goal is to generate innovative concepts on different ways to lock door and frame on behalf of Assa Abloy, the goal is also for the concept to meet the requirements for safetyclass 5.The questions that will be answered in the report are what new innovative possibility to lock a door is there and does the concept fulfill security requirements for Scandinavian locks. First the report presents the theoretical background that contains the theories and tools that form the basis of the work. The work has been carried out with design-product development processes according to methods adapted to the project.The work includes an analysis of the market that together with requirements and target specificationsforms the basis for the concepts generated. The concepts have been generated through internal and joint brainstorming. A total of 48 concepts were generated and screened against three control questions. The remaining 17 concepts were screened in Pugh's matrix resulting in 4 remaining concepts. Physical models were developed for the four concepts and presented at a workshop. 3D printing was used for the conceptmodeling. With a concept selection workshop, a final concept was developed with the help of the participants opinions and ratings of the concept's properties, based on several selected questions.The project resulted in one concept including several components that were prototyped. The components were made with additive manufacturing and then implemented in an already existing lockcase. To demonstrate and visualize their function and to prove the concept itself works. Whether the concept can meet the security requirements for Scandinavian locks cannot be determined as this would require physical tests that would require a prototype made with the final manufacturing method in the final materials. This is also due to the approach of implementing the concept in a lock housing with a lower security class than the target. This is something that is interesting to investigate in future studies since testing is beyond the scope of the delimitations.

Produktionsoptimering av elektromagnetiska omrörare - "ORD 43P" och "EM Stabilizer"Kabroo, Carl Gustaf, Willenius, Robert January 2013 (has links)
Examensarbetet inom produktutveckling – konstruktion utfördes under perioden februari till juni 2013 och omfattar 15 högskolepoäng (C-nivå), och är den slutliga kursen inom högskoleingenjörsprogrammet Innovation och produktdesign. Examensarbetet behandlade problematiken kring produktionsanpassning och kostnadsoptimering av två stycken elektromagnetiska omrörare vid företaget ABB, Process Automation, Metallurgy i Västerås. Efter kontakt med handledaren från ABB, Jan-Erik Eriksson, påbörjades projektarbetet med att tillverkningsanpassa konstruktionen av produkterna ORD 43P och EM Stabilizer. För att åstadkomma kostnadsoptimerad och produktionsanpassad konstruktion tillämpade författarna följande produktutvecklingsverktyg: Design for Cost, Design for Manufacture och Design for Assembly. För att kontrollera att konstruktionen blev optimal, men också att den inte brister under belastning använde examensarbetarna det datorbaserade hållfasthetsverktyget finita elementmetoden i CAD-programmet SolidWorks. Val av komponenter baserades på komponenternas pris per kilo. För att välja det optimala materialet, det vill säga högsta hållfasthet till lägsta pris använde författarna materialdatabasprogrammet CES EduPack. De utvalda materialen från programmet kunde inte författarna påfinna som standard på marknaden, varför författarna ändrade strategi till att jämföra och välja material utifrån marknadsundersökning av standardmaterial hos leverantörer. ORD 43Ps komponenter optimerades konstruktionsmässigt gentemot befintliga komponenter och härvstag och isolerplattor kostnadsreducerades markant. Komponenten stomme grundutförande undersöktes översiktligt. Genom att produktutveckla komponenterna härvstag, isolerplattor och stomme grundutförande minskade kostnaderna för ORD 43P med 2,47 %. Författarna ansåg att ORD 43Ps totala kostnader kan minska mellan 10-25 % eftersom många av dess komponenter är överdimensionerade och består av dyrare material än vad som krävs. EM Stabilizer’s komponenter, lock och tryckluftsslang, utformades med optimal konstruktion och kostnadsreducerades. Genom att produktutveckla komponenterna lock och tryckluftsslang minskade kostnaderna för EM Stabilizer med 1,3 %. Författarna förmodar att EM Stabilizer’s kostnader kan minska, eftersom den är relativt ny på marknaden. ABB vill säkerställa att produkten uppnår sin garanterade livslängd genom att överdimensionera många av produktens komponenter och använda dyrare material än vad som är nödvändigt. / The thesis in product development – design was carried out between February and June 2013 and includes 15 credits (C-level), and is the final course of the Bachelor Program in Engineering, Innovation and Product Design. The thesis dealt with the problem of adaptation to production and cost optimization of two pieces of electromagnetic stirrers at the company ABB, Process Automation, Metallurgy in Västerås. After contact with the supervisor from ABB, Jan-Erik Eriksson, the project work commenced to adapt the manufacturing design of the product ORD 43P and EM Stabilizer. To achieve cost-optimized production and production adapted design, the authors applied the following product development tools: Design for Cost, Design for Manufacture and Design for Assembly. To verify that the design was optimal, but also that it did not break during stress, the authors used the computer based module finite element method of the CAD program SolidWorks. The selection of components was based on the component’s price per kilo. To select the optimum material, that is high strength and affordable, the authors used the material database software CES EduPack. The materials selected from CES EduPack could not be found by the authors as standard material at the market. Therefore, the authors changed strategy to compare and select materials based on market research of standard materials with suppliers. The components of ORD 43P were optimized in terms of design in comparison with existing components coil bracket and insulation boards. They were also cost reduced significantly. The component frame base was examined briefly. Through product development the components coil bracket, insulating boards and frame base the total cost of ORD 43P was reduced by 2,47 %. The authors found that the total cost of ORD 43P could be reduced between 10-25 % as many of its components are oversized and made of more expensive materials than needed. The components of EM Stabilizer, cover and pneumatic hose, were designed with optimum design and was cost reduced.Through product development the components cover and pneumatic hose the costs of EM stabilizer were reduced by 1,3 %. The authors assume that the costs of the EM Stabilizer can be reduced, because it is relatively new at the market. ABB want to ensure that the product reach its guaranteed life by over-sizing many of the components of the product and use more expensive material than necessary. / Kostnadssänkningsprojekt
