Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing beverage containers fail to maintain hot liquids at a desired temperature for an extended period, leading to unsatisfactory or unsafe consumption, especially for infants consuming baby formula.
Innovation Solution
A flexible sleeve with a reflective surface and heating element is designed to wrap around beverage containers, using insulating materials to absorb and store heat, and optionally including temperature and pressure sensors for controlled heating, ensuring the beverage remains at a consistent temperature.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If insulating materials are used in beverage containers, then the cooling rate is reduced and the beverage remains safe to drink longer, but the beverage cannot be maintained at an elevated temperature for a prolonged period
Solution Approach 1:
The heating element is activated before the beverage is poured into the container, pre-heating the container walls and insulating materials. This preliminary heating action ensures that the container is already at an elevated temperature when the beverage is added, extending the period during which the beverage remains at a satisfactory drinking temperature.
Solution Approach 2:
The heating element provides continuous or periodic heating to maintain the beverage temperature at an elevated level throughout the drinking period. This continuous useful action counteracts the natural cooling effect, ensuring the beverage remains warm enough for satisfaction while the insulating materials prevent excessive heat loss.
2Temperature
If heating elements are added to beverage containers, then the beverage can be maintained at an elevated temperature, but the device complexity increases
Solution Approach 1:
The heating element is constructed as a flexible thin film that can be wrapped around the interior surface of the beverage container. This flexible film design minimizes the added structural complexity while providing effective heating, as it conforms to the container shape without requiring rigid mounting structures or complex wiring arrangements.
Solution Approach 2:
The heating element's electrical resistance and power output are optimized to provide sufficient heating power while consuming minimal energy. By carefully selecting the electrical parameters and heating surface area, the system achieves effective temperature maintenance with a simple, low-power heating element that does not significantly increase device complexity.
3Reliability
If the beverage cools down too much, then the beverage becomes unsatisfactory or potentially dangerous, but waiting for hot beverages to cool can take too long
Solution Approach 1:
The heating element operates continuously or periodically to maintain the beverage temperature within the safe and satisfactory drinking range throughout the entire drinking period. This continuous heating action eliminates the need for waiting periods and ensures the beverage remains at an appropriate temperature from pouring to consumption.
Solution Approach 2:
A temperature sensor monitors the beverage temperature and provides feedback to the control system, which adjusts the heating element's power output accordingly. This feedback control ensures the beverage is maintained at the desired temperature range, preventing both excessive cooling and overheating, thereby ensuring safety and satisfaction without requiring user intervention or waiting time.
