Abstract

This research presented the method of improving the existing hygienic urinal system using the integrated approach. Thus, various design activities have been involved in designing and fabricating the proposed product. The aim of this research is to design and fabricate a new hygienic urinal system for solving the person who has difficulty accessing the toilet. The design process is based on the integrated method or Pugh's approach which includes various design activities such as market investigation, concept generation, concept selection, detail design and rapid prototyping concept. Investigating the existing similar product was carried out in order to ideate and generate the idea to improve the previous product. Analytical Hierarchy Process (AHP) and Technique for Order of Preference by Similarity to Ideal Solution (TOPSIS) were employed to decide the best design concept during the selection process at the conceptual design stage. 3D modelling and design analysis were conducted using SolidWorks at the detail design stage and finally, the best-proposed design was fabricated using a 3D printer. The improvement of the hygienic urinal system from the existing design to the proposed design showed that the 41% is the highest improvement in the total number of parts of the hygienic urinal system. The result showed that the proposed new design able to withstand the maximum impact force (195.042N) before it was cracked or fractured which is better than the previous design. The results also revealed that the maximum height to protect the main part (housing) of the proposed new design from cracking was 4.82 m which is better than the existing design. In conclusion, the proposed new design of the hygienic urinal system is much better in terms of its functionality and performance compared to the existing design.
