According to Ministry of Health, Indonesia’s population who needs wheelchairs reaches 1.334.920 people. Based on a preliminary survey conducted, 157 out of 185 medical workers stated that they had difficulty to transfer wheelchair patients. Therefore, it is urgently needed a tool that able to help transferring wheelchair patients, either by medical workers or patient caregivers. The purpose of this research is to identify needs of medical workers, caregivers, and patients, and to design a product concept based on these needs. The methods used in this research is Quality Function Deployment and Kano Model. Activites in this research began with pre-questionnaire to get consumers’ point of views on the difficulties of transferring patients. The next activity is a questionnaire to formulate Voice of Customer (VoC). The next stage is to group VoC with Kano Model to determine which VoC will be used as the basis for product design. After that, a House of Quality was compiled which produced technical attributes, targets, and various aspects as the basis for formulating product concepts. The next stage is generating product concepts that produce several combinations of product concepts using an anthropometric measurement approach of the human body and concept classification trees and concept combination tables. The last stage is the selection of product concepts from several alternative product concepts, using a concept screening approach, concept assessment, and concept testing using Garvin quality dimensions as indicators. The final product concept of chair-to-chair patient transfer aids resulted in a combination of the best product concepts from several alternative product concepts. With these results, a chair-tochair patient transfer aid was designed with ABS material, 105 cm x 38 cm x 2,5 cm dimensions, and 38 cm diameter circular slide board, that able to move patients weighing up to 220 kg. The product expected to facilitate the easy and safe transfer of wheelchair patients. Due to time constraints, product prototypes were not produced and tested. Suggestions for further research are testing product prototypes and estimating costs for sales.
