Effect of Age and Technology on the Perception of Obsolescence: Case Study of Domestic Vacuum Cleaning Appliances

Abstract

Formal or perceived obsolescence occurs when a user decides to stop using a product despite its proper functioning. This is because the design of the product is considered obsolete, generating a negative connotation. Such constant changes in the product to adapt to the latest technologies are responsible for this situation. The aim of this study is to analyse the influence of technology on the perception of obsolescence in the design factor. For this purpose, a total of 297 users were surveyed about their perception of formal obsolescence in relation to certain parts of different household hoovers, focusing on design aspects. Alongside this, technological characteristics are included to assess the effect of old or modern technology on the respondents’ perception of obsolescence. A Chi-Square statistical analysis has been used to evaluate the correlations found, showing that the technological factor affects the design aspects in the case of this product. The results obtained may be useful for design engineers to develop more durable products, as well as to reduce the environmental impact.
