This study employs the TRIZ (Theory of Inventive Problem-Solving) approach to develop an optimal design for a laparoscopic surgeon's chair, focusing on ease and usability. The design adheres to ergonomic principles and includes adjustable components for height, level, and positioning to accommodate individual preferences. The TRIZ methodology, which involves function analysis, cause-effect chain analysis, trimming, engineering and physical contradictions, and inventive principles, was used to identify and address issues in the existing chair designs. The resulting design is comparable to those offered by medical corporations and is prepared for prototyping. The study highlights the potential of TRIZ in enhancing the ergonomics and comfort of laparoscopic surgery chairs, potentially reducing physical strain and improving surgical efficiency.This study employs the TRIZ (Theory of Inventive Problem-Solving) approach to develop an optimal design for a laparoscopic surgeon's chair, focusing on ease and usability.
