Abstract

Opening from an examination of all the best features of accomplishment of the hoverboard, a modern vehicle for urban transport, the authors have created inventive ideas to design the transport means itself. Quality Function Deployment methodology provided the requirements to start from, while the TRIZ methods have provided us the proposals and notions of an innovative landscape to which the authors tend. In practice, while the QFD methodology has a powerfully conceptual appeal, and it is the basis of our analysis, the TRIZ method gives a more innovative thrust and deals the aspects that are strongly constructive and concrete. The Matrix of Contradictions was used within the Hill Model, and through it, the authors have been able to rework the innovative problems, suggested by the QFD analysis, in terms of technical contradictions. At the end of the work, a number of suggestions were made to further innovate this urban and modern means of transport: the hoverboard.

1. Triz For Innovative Architecture

The TOP-FLOP analysis implemented by L. Frizziero, Conceptual design of an innovative electric transportation means with QFD, bench marking, top-flop analysis (Frizziero, 2018; Francia et al., 2017; Meuli & Raghunath, 1997; Ramalingam et al., 2018) allows the identification of sixteen main performance features of an innovative electric transportation (Bosso et al., 2018; Ranjan et al., 2016): the hoverboard. (read 4.1 Bench Marking Analysis: results).

Based on these features, an analysis will be conducted through a TRIZ methodology, that will lead to some innovative architecture of the system-hoverboard (see Figure 1).

Eight of these features have been preferred over the others because they have the ability to make the hoverboard more powerful (Caligiana et al., 2017; Frizziero et al., 2017). The eight features identified are the following:

  • 1.

    Hoverboard Speed (Km/h)

  • 2.

    Battery Endurance (h)

  • 3.

    Battery Charge Time (h)

  • 4.

    Hoverboard Weight (Kg)

  • 5.

    Hoverboard Length (mm)

  • 6.

    Hoverboard Width (mm)

  • 7.

    Hoverboard Height (mm)

  • 8.

    Hoverboard Max Power (Watt)

Starting from the features that improve the performance of the hoverboard identified through the QFD analysis a TRIZ methodology will be applied to find some innovative solutions to improve the hoverboard overall performance (A. Freddi, 2005; Ishak et al., 2018).

Improving the eight identified features will lead to the improvement of the hoverboard performance. However, this could lead to a “technical contradiction”. A “technical contradiction” is defined as a situation in which the improvement of one feature brings on the deterioration of another feature within the same technical system.

Technical contradictions are a typical aspect of the evolution of a technical system.

“Contradiction” is also one of the main postulates of TRIZ theory. This theory implies that a contradiction is the most important obstacle that limits the evolution of a technical system. As a consequence, the evolution of technical systems is strongly influenced by the resolution of contradictions.
