A jamming pad that expedites the securement process of wheeled mobile devices on paratransit services. The Friendly Securement is a device with jamming granules that can change state from a liquid to a solid, allowing this pad to mold around any wheeled shape. All public transit buses are required to have securements in the designated ADA station of the bus.

These typically are belted J-hooks that come from Sure-Lok, a specialist manufacturer of tied securements that attach to the seated base of a wheelchair, however not everyone that uses a wheeled device is in a wheelchair. Bus drivers have to be certified to install the Sure-lok to people's wheelchairs and often require assistance. We want to focus on that problem by creating a more generic solution, that will not replace the current system, but work with it to allow the locking of carts and walkers to that space, where sitting and getting up from a seat can be difficult.
There currently is not a way to secure casters in a bus, until now. The Friendly Securement would reduce some of the anxieties of bus travel and injuries by updating the securement design to be universal to various mobility devices ( conventional and unconventional) with the click of a button to lock and release.
Two or more people in wheelchairs and other wheeled devices taking the same bus can share securement stations with out worry of unjoining. Color will indicate when in use and when the lock button has been pressed. Current bus model only take some wheeled person at a time!
A bladder with coffee grounds as grains are enclosed with silicone shell. When air is subtracted from this bladder the arm can grip whatever it is holding on to. It is using the same physics as wet sand on the beach that is less exposed to air.

This showcases the threshold changes between states of jamming and unjammed.
