This study presents a TRIZ-based method for developing a conceptual laparoscopic surgeon's chair. The TRIZ approach, a systematic method for solving inventive problems, was applied to design a chair that enhances the ergonomic and functional aspects of laparoscopic surgery. The chair was designed with adjustable components to accommodate the needs of surgeons, including height and level adjustments, and customizable positioning. The design adheres to ergonomic principles, even without formal testing, and is comparable to existing medical chairs. The chair's design includes adjustable backrests, armrests, and footrests, enabling surgeons to maintain a neutral posture during procedures, thereby reducing physical strain. The TRIZ methodology was used in conjunction with functional analysis, cause-effect chain analysis, and trimming techniques to identify and resolve design issues. The chair's design was optimized to address engineering contradictions, such as the need for comfort without increasing complexity. The study also highlights the integration of TRIZ with other methodologies like QFD and the Analytic Hierarchy Process to enhance the design process. The final chair concept includes adjustable features that support both relaxation and laparoscopic surgery, demonstrating the effectiveness of the TRIZ approach in developing innovative and ergonomic medical equipment. The study concludes that TRIZ provides a robust framework for addressing complex design challenges in medical engineering.This study presents a TRIZ-based method for developing a conceptual laparoscopic surgeon's chair.
