Research continues on the design of products that do not create serious problems for sustainable development and natural ecosystems. What should be considered in the design to minimize harmful consequences in the product’s entire lifespan, such as the manufacturing process, during use, and after the end of its life?Heating and cooking methods, which have been used in traditional Korean houses for more than 1,000 years, are observed in terms of TRIZ’s resource analysis, systematic thinking, and functional analysis, and the characteristics found in them are summarized. It extracts the characteristics of the concept of a circular economy by analyzing its technological system properties, interactions of constructs, invention principles, and resource properties over time. Ondol systems are highly recyclable, with most of the components that make up the system from a circular environment perspective being reused as a cycle of resources.Thus, these features demonstrate the importance of predicting and analyzing the interactions of each configuration over time as an extension of system thinking in the early stages of planning a technical system, in the resource analysis and utilization of the components that make up the system in conceptual design.
