Temperature-Controlled Coaster to Maintain Hot Drink Temperature for Cold Region Bedroom Users

Users living in cold regions place hot water bottles or hot drinks bedside at night, but beverages cool rapidly within a short time, resulting in a poor drinking experience. They need a product that can effectively maintain temperature.

Who would pay

Users of hot drink bottles and cups in cold regions, especially office workers or home dwellers who need overnight warming.

Current workarounds

Currently, cups and thermos bottles have limited heat retention and cannot continuously heat, forcing users to drink quickly. There is a lack of convenient devices for continuous warming.

MVP idea

Develop a coaster with temperature control function that transfers heat to the cup bottom to maintain drink temperature for a long time, improving the problem of quick cooling.

How to validate

First produce a low-cost controllable temperature coaster prototype to test actual heat retention and user feedback. The risk is that cost and product size might affect acceptance.
