5 Service Design of Rehabilitative Exoskeleton for Sustainable …

5.5 Conclusion
This paper first presents the methods of service design driven by sustainable value
goals. The sustainable value was conceptualized based on the understanding of value
from a sustainable point of view that includes economic, social and environmental
perspectives and then characterized by general sustainable requirements. Thus, the
total sustainable value of product and/or service can be evaluated as the level of total
satisfaction of value requirements. The sustainable value driven product and service
design is proposed as the strategic process of translating sustainable value requirements into product and service technological solutions. The concept of “domain”
from Axiomatic Design is employed to characterize stages of the translation, while
the simplified QFD is employed for organized mapping between design semantics
among domains.
Then, based on the architecture of the Chinese rehabilitation service delivery
system, the three-stage stroke rehabilitation scenario is proposed. The critical sustainable value requirements of general customers and business are identified. By the
proposed QFD-based method, service options are generated in consistency with
product design concepts. In addition to conventional services such as pre-sale consultation, in-use technical support, maintenance and upgrade, the customized configuration, leasing and sale financing, tele-monitoring and supervision, cloud-based data
service are proposed to address requirements from boarder value perspectives. Thus,
the proposed sustainable value-driven service design may provide insights to rehabilitative exoskeleton developers and manufacturers in servitization of the emerging
technology.
