Solution Overview

Problem

Conventional heat patches for relieving neck and back tension are unsustainable, cause skin reactions, lack temperature regulation, and restrict movement due to their inflexible design and reliance on chemical reactions, leading to short-term pain relief and potential skin injuries.

Innovation Solution

A thermal pad with an adhesive surface, a heating element, and a control unit that converts electrical energy into thermal energy, allowing for adjustable and controlled heat delivery, integrated with sensors for posture feedback and radio communication for efficient and sustainable pain management.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Use of energy by moving object

If chemical heat patches are used to generate heat, then heat therapy can be provided without external power sources, but skin rashes and allergic reactions occur due to chemical reactions

Engineering Contradiction:
Improveheat generation capabilityVSAvoidskin reactions
Core Design Contradiction:
Use of energy by moving objectVSObject-affected harmful factors

Solution Approach 1:

The patent replaces chemical energy conversion with electrical energy conversion. Instead of using chemical reactions (exothermic processes) to generate heat, the invention uses an electrical heating element that converts electrical energy directly into thermal energy through resistive heating. This substitution eliminates contact with chemical substances that cause skin reactions, while maintaining the heat generation function.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Ease of operation

If conventional heat patches are used, then portability is achieved, but freedom of movement is restricted due to inflexible design and power cord requirements

Engineering Contradiction:
ImproveportabilityVSAvoidfreedom of movement
Core Design Contradiction:
Ease of operationVSAdaptability or versatility

Solution Approach 1:

The heating pad is designed with a flexible, thin structure that can conform to body contours and move freely with the user. The device eliminates rigid power cords and bulky components, creating a portable unit that maintains flexibility and adaptability for various body positions and movements.

Inventive Principle:
Principle #30Flexible shells and thin films

3Temperature

If constant heat supply is provided by heat patches, then therapeutic heat can be maintained, but muscle tissue becomes accustomed and relaxing effect is reduced

Engineering Contradiction:
Improvetherapeutic heat maintenanceVSAvoidrelaxing effect duration
Core Design Contradiction:
TemperatureVSDuration of action of moving object

Solution Approach 1:

The control unit implements periodic or intermittent heating cycles, alternating between heating phases and cooling phases. This periodic action prevents continuous heat exposure that causes muscle accommodation, while still maintaining therapeutic benefits through repeated thermal stimulation. The system can switch between different heating patterns including continuous, intermittent, and cyclic modes.

Inventive Principle:
Principle #19Periodic action

4Object-affected harmful factors

If heat patches are applied only to painful areas, then localized pain relief is achieved, but new tension develops in other body parts due to compensatory posturing

Engineering Contradiction:
Improvelocalized pain reliefVSAvoidnew tension in other areas
Core Design Contradiction:
Object-affected harmful factorsVSObject-generated harmful factors

Solution Approach 1:

The heating pad is designed to provide both localized and distributed heating modes. It can concentrate heat on specific painful areas when needed, or distribute heat more broadly across larger muscle groups to prevent compensatory tension. The flexible design allows adaptation to different application scenarios, making it versatile for treating both focal and regional musculoskeletal issues.

Inventive Principle:
Principle #6Universality (Multi-functionality)

5Power

If larger heating pads connected to electricity are used, then sufficient thermal energy can be delivered, but freedom of movement is severely restricted by power cord requirements

Engineering Contradiction:
Improvethermal energy deliveryVSAvoidfreedom of movement
Core Design Contradiction:
PowerVSAdaptability or versatility

Solution Approach 1:

The system separates the power source from the heating element, allowing the heating pad to be a lightweight, portable unit while the power source can be positioned independently. This segmentation enables sufficient power delivery without requiring a long power cord attached to the heating pad itself, improving mobility and freedom of movement.

Inventive Principle:
Principle #1Segmentation
