Entwicklung eines Vorgehensmodells zur automatisierten Ähnlichkeitssuche in den frühen Phasen der Produktentwicklung

Description

Use of existing data in the product development process promises increased product quality, fewer risks in development and less time and cost requirements. Overall, fewer resources are required for the development of new products, which leads to sustainable product development. However, the different data formats in the concept and design phases (e.g. principle sketches, components or assemblies) are a challenge for the use of similarity search. As a result, a modular procedure has been developed as part of this thesis, which enables the search in the early phases of product development through the use of data-driven methods. Firstly, a solution for principle sketches was developed, which recognises the sketches and then automatically converts them into a graph. This forms the basis for the search for similar sketches, whereby different formats can be used as search input. In addition to the sketch search, a procedure is also presented in the work, which enables the linking of sketches and 3D assemblies, whereby 3D data is integrated into the development process at an early stage. Finally, a similarity search for components was created and then compared with the state of the art. Overall, the various modules have the same objective: to find and utilise existing data as effectively as possible.
