Directing resources back to the economy is becoming a focus point for practical and theoretical research. Extending the useful life of electronic household devices through design for repairability is a viable method for preserving resources for a longer time, which has a positive impact on the environment and the economy. In my thesis I present the main motivating and demotivating factors for companies and consumers with regard to repairs, and I describe guidelines that can help product designers in the process of design for repairability in the case of electronic household devices. I define four main categories for product design methods, based on the key issues of repair: Availability, Diagnosis, Sources and Action. This can contribute to the deeper understanding of the repairability of our modern devices and can guide consumers in having their household appliances repaired.
