As a single designer has not all knowledge about all aspects of the product, the design has to be verified by other experts. The design may have to be changed, is further detailed, again verified and approved, and so on, until it is ready. But only the final product, once it exists, will prove the correctness of the design. Given the complexity of modern industrial products, the intermediate verification and change processes require substantial time. This has a major negative impact onthe development time and costs of the product. Cognitive Product Development, as proposed here, approaches design as a scientific learning process. It is based on a well known and successfully applied theory for Cognitive Psychology. In stead of relying solely on the experiences of a single individual, CPD makes the combined knowledge of multiple disciplines, acquired throughout the life of existing products, available through generic design objects. CPD thus approaches design as the configuration of existing and verified knowledge. It is expected that this accelerates the product development process and results in designs of higher quality and reliability without affecting the creative freedom of the designerTrenutna praksa konstruiranja je takšna, da konstrukterji običajno začnejo nov projekt s praznim listom papirja ali v praznem modelirnem prostoru. Ker posamezen konstrukter nima vsega znanja o vseh vidikih izdelka, morajo njegovo zasnovo potrditi se drugi strokovnjaki. Zasnovo je včasih treba spremeniti, dopolniti, ponovno preveriti ter potrditi in tako naprej, dokler ni pripravljena. Vendar bo samo končni izdelek, ko je enkrat končan, pokazal, če je zasnova pravilna. Glede na zapletenost danasnjih industrijskih izdelkov so vmesna preverjanja in spreminjanja časovno precej potratna, kar zelo negativno vpliva na trajanje razvoja in ceno izdelka. Kognitivni razvoj izdelka (CPD), kakrsnega predlagamo na tem mestu, se konstruiranja loteva na način znanstvenega učnega postopka. Temelji na dobro znani in uspešno preizkušeni teoriji kognitivne psihologije. Namesto da bi se zanašali izključno na izkušnje vsakega posameznika, CPD združuje znanje z različnih področij, ki se zbira skozi celotno dobo trajanja obstoječih izdelkov, in ga ponuja preko generičnih konstrukcijskih objektov. CPD torej obravnava konstruiranje kot konfiguracijo obstoječega in potrjenega znanja. Pričakujemo,da se bo na ta način pospešil proces razvoja izdelkov. To naj bi pripomoglo k hitrejšemu razvoju izdelkov in posledično k njihovi višji kakovosti in zanesljivejšim zasnovam, ne da bi s tem prizadeli kreativno svobodo konstrukterjevTEXTznanstveno časopisjejournalsSlovenian National E-content AggregatorNational and University Library of SloveniaUniverza v Ljubljani, Fakulteta za strojništvo
