With the aging of the population, old people increasingly wish to stay at home before entering to a retirement home. There are several reasons such as: the cost of entry, the impersonal side and the lack of solicitation as well isolation and lack of identity are the elements that could delay the entry into the retirement home. In this research, we would like to focus on persons with major neurodegenerative disorders who would like to stay at home as long as possible. These disorders are more and more present with aging of population, which lead us to reflect on the future home 4.0 by permitting residents to live their activities of daily living (ADL).New technologies and connected objects could be the potential solutions for designing the future home. During this study, we will identify the contradictions that could be existed among different solution’s concepts based on functional criteria. These criteria are proposed in parameters according to the TRIZ method in order to propose principles of solution’s concepts.
