Abstract [en]

Product development is a collaboration-intensive process resulting in a novel or enhanced product that satisfies the customers' needs. To meet those needs, functional requirements are defined, which ultimately determine the product's physical characteristics and manufacturing. However, the functional and other non-geometrical information becomes less noticeable as the process advances, since the primary representation of the product design in the latter stages of the product development is often a purely geometrical model, causing information fragmentation. This fragmentation hinders the collaboration between different stakeholders while neglecting valuable product information that could facilitate its manufacturing. Research to date has not yet provided a suitable way to link the geometrical model of a product with its non-geometrical information. Focused on the assembly domain, this work proposes a way to integrate functional information into the product's geometrical model by using assembly features, which could be employed in the latter stages to extract process constraints and additional product details relevant to assembly process planning, as shown in the developed case study. This paper provides new insights into the value of the assembly feature as a functional information carrier and a tool for improving the collaboration between different stakeholders during the product development process.

Abstract [en]

Digital product development that combines diverse expertise can strengthen the ability to create products that meet customer demands in a commercially viable way. In the early stages of this process, user requirements are translated into technical specifications that define a feasible product concept. Therefore, concept detailing in these stages is essential for manufacturing, as they impact process selection and resources required to manufacture the product.

Given the high proportion of assembled products, assembly becomes an important manufacturing process to study, especially in terms of deriving and propagating product characteristics relevant to this process throughout product development.

One major research gap is the lack of a unified way to represent and distinguish product characteristics defined during design to facilitate assembly, which later serve as essential information for this process.

Multiple research efforts have addressed this issue by proposing various specialized information models for assembly, yet a suitable way to represent this information integrated with the product model is still missing.

This thesis addresses this issue focusing on handling activities for automated assembly by providing a threefold contribution: identifying a core concept to represent assembly information, proposing a way to incorporate assembly information within the product information model by leveraging an international standard, and gathering industry experts' insights to improve this approach for broad and quick adoption.

The outcome of this thesis facilitates the integration of stakeholder information early in product development while providing a space to capture design intent. It also streamlines the identification and subsequent extraction of product information that is decisive in designing dedicated specialized equipment, such as feeders, grippers, and fixtures. Thus, this thesis enables enhancement of communication between design and manufacturing and simultaneously bridges the product and resource life cycles.

Abstract [sv]

Digital produktutveckling som kombinerar expertkompetenser kan stärka förmågan att skapa produkter som möter kunders krav på ett kommersiellt gångbart sätt. I de tidiga faserna av denna process omsätts användarkrav till tekniska specifikationer som definierar ett genomförbart produktkoncept. Därför är konceptdetaljeringen i dessa faser avgörande för tillverkningen, eftersom de påverkar val av processer och de resurser som krävs för att tillverka produkten.

Givet den höga andelen monterande produkter blir montering en avgörande tillverkningsprocess att studera, särskilt när det gäller att härleda och fördela produktegenskaper relevanta för denna process genom hela produktutvecklingen.

Ett stort forskningsgap är avsaknaden av ett enhetligt sätt att representera och särskilja de produktegenskaper som definierats under konstruktion för att underlätta monteringen och som senare utgör väsentlig information för denna process.

Flera forskningsinsatser har fokuserat på detta problem genom att föreslagit olika specialiserade informationsmodeller för montering, men ett lämpligt sätt att representera denna information integrerat med produktmodellen saknas fortfarande.

Denna avhandling adresserar detta problem genom att fokusera på hantering vid automatiserad montering genom att ge ett tredelat bidrag: identifiera ett huvudkoncept för att representera monteringsinformation, föreslå ett sätt att integrera monteringsinformation inom produktinformationsmodellen genom att utnyttja en internationell standard, och samla insikter från experter i industrin för att förbättra denna metod för ett brett och snabbt införande.

Resultatet av denna avhandling underlättar integrationen av intressenters information tidigt i produktutvecklingen samtidigt som det ger ett utrymme för att fånga konstruktionens avsikt. Det effektiviserar också identifieringen och den efterföljande användningen av produktinformation som är avgörande för konstruktion av specialiserad utrustning, såsom matare, gripare och hållare. På så sätt möjliggör denna avhandling förbättrad kommunikationen mellan konstruktion och tillverkning och skapar samtidigt en brygga mellan produktens och resursernas livscykler.
