This paper examines the “reverse innovation” of the leveraged freedom chair (LFC), a high-performance, low-cost, off-road wheelchair originally designed for developing countries. A needs study of 71 developed world wheelchair users was conducted through three different data collection efforts. These data were contrasted with studies of 125 developing world wheelchair users, who were shown to be lead users for their developed world counterparts. The GRIT freedom chair (GFC), the developed world version of the LFC, was designed based on results of the study. By recognizing developing country users as lead users, designers can reveal latent needs and create globally disruptive innovations.

Fig. 5

Needs of developed world WC users, expressed before and after prompting about features of the LFC. Needs are weighted from 5 to 1, with 5 being the most important. All needs (except those in parentheses) were also elicited from developing world user needs. Needs underlined are likely latent because of their significant increase in priority when reported after prompting about LFC features. The “others” are generally related to specific use scenarios and were not included in the set of potential latent needs. The needs in this figure correspond to the total number of needs in the right-hand section of the Venn diagram in Fig. 2.

When the wheels are removed, the drivetrain remains attached to the frame of the chair. The moving parts, freewheel, and coupling utilize standard bicycle parts.
