Solution Overview

Problem

Existing stuffed animal warming devices lack efficient and user-controlled heating solutions that provide consistent warmth to the user, often relying on transient phase materials or simple heating coils without intuitive control mechanisms.

Innovation Solution

A stuffed animal device with integrated heating coils distributed across its body, arms, and legs, along with a user-accessible control system that allows for adjustable heat settings and includes light emitters for ambiance, utilizing a power supply and insulating layers to enhance warmth distribution.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If transient phase material or simple heating coil is used, then heating function is provided, but user control and consistent warmth are insufficient

Engineering Contradiction:

Improveuser controlVSAvoidconsistent warmth

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The patent implements a dynamic control system with multiple heating elements that can be independently activated based on user-selected intensity levels. The controller dynamically adjusts which heating elements operate and at what power level, providing both user control and consistent warmth through adaptive heating rather than static phase-change materials.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The heating system is divided into multiple segmented heating elements distributed throughout the stuffed animal body. This segmentation allows selective activation of different regions based on user needs and enables more precise temperature control compared to a single heating element or passive phase-change material.

Inventive Principle:

Principle #1Segmentation

2Temperature

If heating element is integrated into stuffed animal, then warmth is provided to user, but heat distribution efficiency needs improvement

Engineering Contradiction:

Improvewarmth to userVSAvoidheat distribution efficiency

Core Design Contradiction:

TemperatureVSProductivity

Solution Approach 1:

Multiple heating elements are strategically positioned in different regions of the stuffed animal body to ensure comprehensive heat distribution. This segmented approach prevents heat concentration in single areas and improves overall thermal efficiency by distributing thermal energy across the entire structure.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Different heating elements can be activated based on local user needs - for example, heating the torso region when the user needs core warmth or extremity regions when hands or feet need warming. This localized heating approach improves heat distribution efficiency by delivering warmth only where needed rather than heating the entire structure uniformly.

Inventive Principle:

Principle #3Local quality

3Productivity

If multiple heating elements are added for better heat distribution, then warmth efficiency improves, but device complexity increases

Engineering Contradiction:

Improveheat distribution efficiencyVSAvoidheating system complexity

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The controller serves multiple functions: it selects heating intensity levels, activates appropriate heating elements, and manages power distribution. This multi-functionality consolidates control complexity into a single component rather than requiring separate controls for each heating element, thereby improving heat distribution efficiency without proportionally increasing overall system complexity.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

Multiple heating elements are electrically connected to a common power source and control circuitry. This merging of heating components into a unified system allows efficient heat distribution while managing complexity through integrated design rather than separate independent systems.

Inventive Principle:

Principle #5Merging (Combining)
