People with physical restrictions such as recovery from hip surgery, broken bones, or those who find it challenging to sit or squat also benefit from these devices.
Cisgender men may also want a urinary funnel if they have medical conditions that make it challenging or impossible for them to stand and pee.
Urinals for a greater variety of bodies have advantages of quick and hygienic use, water conservation, and less need for physical space.
Speed of use can be especially important when there is high peak demand, such as in music festivals, theatrical events, sports stadiums, discos, dance clubs, and convention halls.
The fixed designs are typically used by women in a "hovering" posture, standing over them with knees slightly bent.
In addition, small portable urinals including sealable collection containers have been available in female-only and unisex versions.
Initially, medical or hospital devices were pressed into service, but designs specially made for travel eventually appeared.
A similar device was patented in 1956: "an efficient urine conductor for use by females eliminating all need for contacting a toilet facility...usable while in a comfortable, erect standing position".
