The Nokia Design Archive, now hosted within the Aalto University repository, provides a detailed look into the industrial and product design history of Nokia. Covering the period from 1990 to 2020, the collection documents the design work conducted at Nokia Mobile Phones and later Microsoft Mobile. The archive serves as a resource for museum activities, academic research, and educational purposes, though commercial use of the materials is strictly prohibited. The repository includes a diverse array of items, such as physical object samples, sketches, mood boards, renders, internal publications, and audiovisual materials. These documents offer insight into the company's design philosophy and product development processes over three decades. Users can browse specific collections, such as donations from individual designers like Chao Huang, which feature sketches and photographs of various hardware including Bluetooth headsets and internet sticks. The Aalto repository, which manages this collection, is a long-term digital preservation system designed to ensure the discoverability and usability of university-held heritage and research data. By centralizing these records, the archive preserves the visual and technical history of a company that significantly shaped mobile telecommunications.
