Portable raised toilet seat
"When I go out visiting or out on a shopping trip I often find the toilet seats too low, so I would like to see if a portable raised toilet seat could be designed. All I can find are the raised toilet seats where the existing toilet seat needs to be removed and then the raised toilet seat needs to be screwed on. [A possible solution would be to] create an inflatable one that can be attached to an existing toilet seat with something like velcro and maybe have a stiff ridge that can be secured under the existing toilet seat."
Happy to hear your ideas!
