Solution Overview

Problem

Existing heating solutions for containers, such as thermoses and mug warmers, require a power supply to function and are ineffective in maintaining hot water temperature over time, especially in areas without electricity.

Innovation Solution

A portable power supply device with a battery-powered heating plate, insulation pad, and wireless charging capability, allowing for heating and warm-keeping of containers without a connected power source, featuring a sealing mechanism to prevent liquid entry and safety features like a mounting bracket and indicator lights.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a conventional thermos or mug warmer is used, then heating function is available, but it requires connection to external power supply which is not available in all locations

Engineering Contradiction:

Improveheating function availabilityVSAvoidpower supply requirement

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent extracts the power supply function from the external grid and incorporates it into the device itself through a rechargeable battery. This allows the heating device to operate independently without external power connection, resolving the contradiction between heating availability and power supply requirement.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The device combines multiple functions including heating, warm-keeping, and wireless charging capabilities in a single portable unit. This multi-functionality enhances adaptability to different usage scenarios while maintaining a compact form factor, addressing both versatility and device complexity concerns.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Ease of operation

If a battery-powered heating plate is used, then portable heating is achieved, but heat insulation is required to prevent energy loss

Engineering Contradiction:

Improveportable heating capabilityVSAvoidheat loss

Core Design Contradiction:

Ease of operationVSLoss of energy

Solution Approach 1:

The patent employs asymmetric thermal insulation design where the insulation pad is strategically positioned between the heating plate and the container. This creates an asymmetric heat flow path that directs heat toward the container while minimizing lateral heat loss to the environment, effectively reducing energy loss while maintaining portability.

Inventive Principle:

Principle #4Asymmetry

3Speed

If heating power is increased to heat water quickly, then heating speed improves, but energy consumption increases

Engineering Contradiction:

Improveheating speedVSAvoidbattery energy consumption

Core Design Contradiction:

SpeedVSUse of energy by moving object

Solution Approach 1:

The patent implements periodic heating cycles with multiple temperature stages. The heating plate operates at high power initially to quickly heat water, then transitions to lower power for maintenance heating. This periodic action achieves fast heating speed while minimizing overall battery energy consumption by avoiding continuous high-power operation.

Inventive Principle:

Principle #19Periodic action
