One factor was the size and weight of structural elements such as the enclosing tent screen and the support for the toilet seat, so it was important to trim down those elements as much as possible. The solution to compensate this was to supplement the functionality by using parts that could serve in multiple roles and by appropriating items which were available.The bag for carrying the kit is designed to be compact and to store 6 items: aluminum pipes and a toilet seat, nylon cloth for the tent, pocket tissues, garbage bags, and coagulant. Furthermore, the kit is slim, so it does not take up space even when stacked or placed in a car trunk or in a storage space at home.
