台灣現有無障礙廁所內設施僅能滿足部分人需求，因缺少照護者替身障者更換衣物、尿布的「照護床」，而照護床體積較大，若要廣泛設置，於都市，易有建築內空間不足問題；於郊區，易有使用率不高導致半荒廢等爭議，導致配有照護床之較完善的無障礙廁所遲遲無法普及。

當5G普及後，資訊傳輸不受限制，無人駕駛系統將會更加完善，能由「人找廁所變成廁所找人｣，相較於一般人，身障者及照護者需要更多的方便性。移動式空間能隨需求靠近使用者所在地，活動範圍將不再受限於設立廁所的地方，且使用上具有更多的彈性。

此提案並非想取代所有定點設置的無障礙廁所，而是希望以互補的方式存在，數量最多的還是一般型，完善型的定點設置在人流較多的機場、大型車站等，機動型則能彌補前兩種的不足，希望透過這三種型態，構成完善且符合使用效益的無障礙廁所系統。達到以最少的設施數量，滿足最多的使用者的效益。

Taiwan's current accessible restroom facilities can only meet the needs of some people, because of the lack of the "care bed" where caregivers exchange clothes and diapers for the disabled. Nevertheless, the size of the care bed is large. If it is to be widely installed in the city, it would likely result in insufficient indoor space. In the suburbs, its low usage rate would likely lead to a semi-disused problem and other disputes. These cause the delay of more accessible restrooms with nursing beds being widely used.

When 5G becomes widely used, the information transmission has no limitation; the driverless system will be more complete. It can turn "people looking for restrooms" to "The restroom finding people". The disabled and caregivers need more convenience than normal people do. When the mobile space placed close to the user's location as needed, the range of activities will no longer be limited to where the restroom is set up, and it will be more flexible in use.

This proposal is not to replace all fixed accessible restrooms; it is to exist in a complementary manner instead. The normal type of accessible restrooms are adopted the most, the integrated type is set at airports and large stations with crowds, and the mobile type can make up deficiencies of the first two. The hope is that these three will form a complete and cost-effective accessible restroom system and achieve the needs of majority users with the minimum number of facilities.
