US Patent 9991683 Refrigerator module utilities enabled via connection

A connection system includes a feature module that supplies various functionalities, a portable countertop stand having an upright section that selectively receives the feature module and an umbilical connecting the portable stand to an external appliance to deliver utilities to the portable countertop stand. A utility port selectively delivers at least one utility to the feature module when engaged with the upright section. A utility receiver removably engages the utility port by hand without the use of tools and selectively receives a predetermined set of utilities when the feature module engages the upright surface. A connection interface detects when the feature module is engaged with the upright section and the predetermined utility set required by the engaged feature module. After the feature module is engaged, the connection interface prompts the utility port to release the predetermined utility set to the feature module.
