With the advent of an aging society, health care
products and services have become increasing important for
the elderly. Elderly aids are often regarded as the most crucial
aspects of new product development in health care. Innovative
methods in wheelchair design most commonly used the Theory
of Inventive Problem Solving (TRIZ) and the Way of Oriented
Innovation Strategy (WOIS) theories for new products. TRIZ
innovation theory uses 39 engineering parameters and 40
inventive principles for innovative research and development.
However, it cannot apply a global view to the whole system.
WOIS theory uses systematic approach with a problem
domain matrix to find contradictions and compensate for
shortcomings from the TRIZ theory. In this study, we
combined WOIS innovation theory and engineering
parameters from TRIZ, using patent analysis techniques to
improve existing product concepts in wheelchair design. This
served to achieve the goal of both innovation and patent design
around for new product development. In this paper, two cases
of manual wheelchairs were investigated using TRIZ and
WOIS innovation theory during the conceptual design phase to
achieve the goal of patent design around.
