Designing an Adjustable Stool for Height Based on Human Design Technology

Abstract

This paper describes how to design an adjustable stool for height based on Human Design Technology (HDT). HDT is a Human-centered Design/product development method of visualizing user requirements, which are extracted by 3P (three-point) task analysis and other tools, via a database of seventy design items and a structured concept. Namely a structured concept is constructed based on user requirements and make them visualized using seventy design items. The seventy design items of HDT are classified into the eight large groups: 1) User interface design (twenty-nine design items), 2) UD (nine design items), 3) Kansei (sensitivity) design (nine design items), 4) Product liability design (six design items), 5) Ecological design (five design items), 6) Robust design (five design items), 7) Maintenance design (two design items), and 8) other (human-machine interface design) (five design items). An adjustable stool for height was designed based on HDT.
