Purpose: The purpose of the work is the generalization of available data on averting and using the thermal deformations in the technology, the analysis of the methods of compensating the thermal deformations with the use of tools TRIZ (Principles, Contradictions, Su-Field analysis, Trends of Development); the determination of the promising tendencies in region (in accordance with the Trends of the Development of Technical Systems). Design/methodology/approach: TRIZ methodology is employed to assist the way to get new drawing which is used to resolve the contradictions. The 40 engineering principles are also used as the design guideline. In order to ensure that the trusts, the components of the frame, remains as the new bus body structure frame is sufficient strong, the FE method is used to validate the strength of the new body design based on the material property selection. Individual frame analysis is implemented. Findings: TRIZ is a problem solving method based on logic and data, not intuition, which accelerates the project team's ability to solve these problems creatively. TRIZ also provides repeatability, predictability, and reliability due to its structure and algorithmic approach. TRIZ is the (Russian) acronym for the Theory of Inventive Problem Solving. TRIZ is an international science of creativity that relies on the study of the patterns of problems and solutions, not on the spontaneous and intuitive creativity of individuals or groups. Practical implications: The TRIZ principle and parameters are applied to assist a light weight bus body design which is compared to the existing design. The bus body model is created by CAD and transfer data to CAE using FE analysis. The weight reduction process is then followed up from the analysis. The new light weight bus body design is tested by the same method of FE analysis. The same result of body strength is accepted and can use for design and manufacturing. Originality/value: Tested TRIZ method can save material used, production cost and time.
