Child car seats are prescribed by law as mandatory for children until certain age and anthropometric conditions have been fulfilled. The market offers a variety of solutions that follow the stages of child development, which leads to the categorization of seats and their users. Although the child car seats have been used in the last decade more than ever in history and have progressed just as well, annual tests for child car seats show that there is no 100% safe seat and that there is still plenty of room for improvement. The aim of this paper is to develop a proposal of design improvement for a child car seat that will provide new, better user experiences and, if possible, to achieve even better safety features. The paper deals with the categorization of products and their users accordingly. By reviewing the regulations and market analysis, a critical group of solutions was identified and the target user population selected. Below is a more detailed look at the child car seats from Group 2/3, which includes children aged 4-12 years, weighing 15-36 kg and height of 100-150 cm. A reference model was selected by comparing their advantages and disadvantages which was further used to evaluate the generated concepts. The patent database was reviewed and some of them were presented regarding advantages and disadvantages of such ideas. That helped with creative thinking. Structural and functional requirements were extracted, a technical questionnaire was implemented, limitations were determined, and project objectives were defined on the basis of all these findings. Concepts have been generated and mutually evaluated by the adjusted potential method with prominent weight factors for each individual product characteristic. Finally, a conceptual CAD model was created for the final improvement proposal and its functionality was discussed with the advantages and expected market competitiveness of the product. The result of this paper demonstrates the possibility of improving the safety and ergonomics of child car seats in an unprecedented way. A prototype should be developed before further consideration to prove its functionality.
