Electric weighted blanket and method for manufacturing the electric weighted blanket

Solution Overview

Problem

Existing electric blankets are often too light and thin, leading to poor use experience due to displacement and inadequate coverage of the human body, while increasing thickness to enhance warming effect compromises comfort and storage space.

Innovation Solution

An electric weighted blanket design that incorporates weighted beads between securing layers, connected by quilting, and heating wires secured within a protective layer to prevent exposure and ensure stability, all sewn into a blanket body with outer material layers.
