Solution Overview

Problem

Existing thermal bottle solutions either passively resist temperature changes or require bulky, potentially toxic heating elements, failing to actively maintain fluid temperature for extended periods while being portable and user-friendly.

Innovation Solution

A flexible tubular sleeve with an elastic band and air-activated chemical heat source elements that can be securely positioned around a bottle to maintain fluid temperature within a desired range (90-104 degrees) for up to 8 hours, allowing for easy bottle and heat source replacement.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Temperature

If passive insulation wraps are used, then temperature changes are resisted, but active heating capability is not provided

Engineering Contradiction:

Improvefluid temperature maintenanceVSAvoidactive heating capability

Core Design Contradiction:

TemperatureVSEase of operation

Solution Approach 1:

The patent combines passive insulation (the tubular sleeve structure) with active heating elements (chemical heat sources) into a single integrated bottle warmer system. The sleeve provides thermal insulation while the chemical heat sources provide active heating, resolving the contradiction between passive temperature resistance and active heating capability.

Inventive Principle:

Principle #5Merging (Combining)

2Temperature

If elaborate thermal elements are used for active heating, then heating effect is achieved, but device complexity and bulk increase

Engineering Contradiction:

Improvefluid heating capabilityVSAvoidstructure complexity

Core Design Contradiction:

TemperatureVSDevice complexity

Solution Approach 1:

The patent employs disposable chemical heat source elements that are simple in structure but effective for heating. These elements are inserted into the sleeve, activated, and then discarded after use, eliminating the need for complex reusable heating mechanisms while providing reliable active heating capability.

Inventive Principle:

Principle #27Cheap short-living objects (Disposable)

3Temperature

If chemical heat source elements are used, then active heating is provided, but potential toxicity and messiness increase

Engineering Contradiction:

Improveactive heating capabilityVSAvoidtoxicity and messiness

Core Design Contradiction:

TemperatureVSObject-affected harmful factors

Solution Approach 1:

The patent uses a flexible tubular sleeve that encloses the chemical heat source elements, containing any potential messiness. The sleeve acts as a barrier that prevents direct contact between the user and the chemical elements, reducing toxicity concerns while maintaining the active heating function.

Inventive Principle:

Principle #30Flexible shells and thin films

4Duration of action of moving object

If extended period heating is provided, then temperature maintenance is improved, but portability and ease of use may be compromised

Engineering Contradiction:

Improveheating durationVSAvoidportability and ease of use

Core Design Contradiction:

Duration of action of moving objectVSEase of operation

Solution Approach 1:

The patent segments the heating system into a reusable tubular sleeve and replaceable chemical heat source elements. This segmentation allows the sleeve to be portable and easy to use, while the heat source elements can be replaced as needed to extend the heating duration. The modular design resolves the contradiction between extended heating duration and ease of operation.

Inventive Principle:

Principle #1Segmentation

Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

Function Achieved in This Case

The solution provides active, portable, and efficient heating of fluids in bottles for extended periods, ensuring the fluid remains at a desired temperature for consumption while being easy to use and maintain, with the ability to reuse the thermal bottle sock after the initial fluid is consumed.

Implementation Method 1

The chemical heat source element may comprise an air activated heat source layer. The chemical heat source elements may be selectively activated when exposed to air, and heat the fluid in the bottle to a desired range.

Methodology Applied

Scientific EffectExothermic reaction: Exothermic Reaction

Implementation Method 2

The chemical heat source elements may have opposing ends each comprising an adhesive layer for adhesively securing the chemical heat source elements to the inner sleeve.

Methodology Applied

AI summary

A bottle warmer includes a flexible tubular sleeve having a closed lower end and an open upper end. The open upper end is to receive a bottle therethough, and the closed lower end is to receive a bottom of the bottle thereagainst. An elastic band is carried by a medial portion of the flexible tubular sleeve to secure the medial portion to an adjacent portion of the bottle, and permit the open upper end to be folded back adjacent the closed lower end to define a pocket. A chemical heat source element is to be received by the pocket for warming the bottle.
