Designing A Sustainable Energy-harvesting Stairway: Determining Product Specifications Using TRIZ Method

In pursue of a new potential sustainable energy source as a respond to global warming, a literature study was conducted, resulting in a decision to design an energy-harvesting stairway that generates electricity from humans stepping movement's potential energy. This paper discusses the planning and the concept developing in designing the stairway. As an initial step, the stairway's product characteristics is defined using brainstorming. The characteristics were later processed into a questionnaire spread to 42 respondents to obtain the stairway's customer's needs. An NPD approach using TRIZ was utilised to determine the stairway's product specification based on the customer needs obtained.
