What change brought the true usability revolution to the electric kettle design?
Answer
Separating the heating element from the main body via a separate powered base.
While internal elements solved the initial engineering challenge of heating water internally, the true paradigm shift in user experience—the usability revolution—occurred when the design evolved so that the kettle simply sat on a separate, powered base. This allowed the user to lift the kettle freely to pour without being tethered by a permanently attached cord, which drastically reduced inherent safety risks associated with moving a hot, wired appliance and simplified the internal plumbing by isolating electrical connections solely to the base plate.
