TRIZ-based method for developing a conceptual laparoscopic surgeon’s chair

Abstract

TRIZ, also known as the theory of innovative problem-solving, has garnered attention from several proponents who advocate its merits as a systematic technique or toolkit that offers a rational framework for fostering creativity in pursuing innovation and creative problem-solving. The broad range of tools and procedures used in the TRIZ-based innovating enable the effective development of next-generation items while successfully enhancing existing ones. Using these tools and approaches may also facilitate the development of the necessary functionality and mitigate the costs associated with manufacturing processes, hence allowing the introduction of novel and enhanced products to be introduced into the market. This study aims to employ the TRIZ approach to develop an optimal laparoscopic chair design. The design of the laparoscopic chair was with a particular emphasis on ease and usability. The laparoscopic chair’s design demonstrated adherence to ergonomic principles despite the absence of actual ergonomic testing. This design has the chair’s adjustable components, which allow for height and level modifications, as well as customizable positioning to accommodate the preferences of the seated individual. The outcome of this design is comparable to laparoscopic chairs offered by medical corporations and preparing for the prototyping phase.
