The re submission of the appearance model of PSS project.
Straight from the 3D-Printer, ABS opaque material - 2.0 mm thickness.
Scale 1 : 5 of the actual size [actual height = 500mm] [model height = 100mm]
The concept product comprise of five parts - (1)outer and (2)inner container, the (3)the seating, the (4) hinge lid, and the (5) urinal basin-cap.
The concept is designed for Kibera resident in Kenya, an African slum with very poor sanitation management, due affordability issue. Therefore the proposed design which is devoid of technology, and design sophistication - the concept is simple assemblage of two containers that match together, and highly intuitive use of the toilet. The other reason for such design, is so that the container can be separated with ease and the product is collected for disposal by a service system [product-service-system].
The concept is an adjustable seat height to accommodate both adult and child user.
The adjusting method is operated by just manually rotating the inner container and let it slide downwards into the outer container - by holding onto the seating, which is screw-threaded to the inner container (like a cap and a bottle), and then the matching ribs will allow the smooth interlocking. So the adjust height for child is simply rotate and push down, and for the adult seat height - simply pull up and rotate slightly, so that the matching ribs are away from each other.
Some concern of this concept is the handling and touch contact between the hands and the product, and the saftey of the push (dop) of the container.
Preferred adult seat of a toilet height is 470mm and a average child at the age of five has a knee length of 300 mm, therefore, the concept product has a transition mode between the two different seat heights.
These data was founded in literature source written by the Ergonomists : Pheasant, S & Haslegrave C. (2006) Body Space - Anthropometry, Ergonomics and the Design of Work 3rd Edition, p.266, Taylor & Francis Group Publication.
