Solution Overview

Problem

Helmets made from conventional protective materials often fail to maintain optimal performance across varying environmental conditions, such as extreme heat or cold, leading to reduced protection due to material softening or hardening.

Innovation Solution

A temperature regulation system integrated into helmets that uses Peltier modules, Phase Change Materials (PCMs), and other technologies to selectively heat or cool protective materials based on environmental conditions, maintaining optimal material properties for protection.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional protective materials are used in helmets, then the helmet provides basic protection, but the material performance deteriorates in extreme temperatures (softening in heat, hardening in cold)

Engineering Contradiction:

Improvematerial protection performanceVSAvoidperformance across environmental conditions

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

The patent applies parameter changes by actively modifying the temperature parameter of the protective materials through heating elements and cooling systems. This allows the materials to maintain their optimal physical properties (ductility, toughness) across a wide range of environmental temperatures, resolving the contradiction between reliable protection and environmental adaptability

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The patent utilizes phase change materials (PCMs) that undergo phase transitions to absorb or release heat, thereby maintaining stable temperatures of protective materials. This phase transition mechanism prevents temperature-induced material property degradation, enabling consistent protection performance in varying environmental conditions

Inventive Principle:

Principle #36Phase transitions

2Reliability

If temperature regulation systems are added to helmets, then material protection performance is maintained across extreme temperatures, but the device complexity increases

Engineering Contradiction:

Improveprotection in extreme temperaturesVSAvoidsystem structure

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The temperature regulation system is segmented into modular components including separate heating elements, cooling systems, and temperature sensors that can be independently integrated into the helmet structure. This segmentation allows for manageable complexity while achieving reliable temperature-controlled protection

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent introduces temperature regulation systems as intermediary components between the external environment and the protective materials. These intermediaries (heating/cooling systems) mediate the thermal interaction, maintaining optimal material properties without requiring direct modification of the helmet's primary protective structure

Inventive Principle:

Principle #24Intermediary (Mediator)

3Reliability

If active heating and cooling systems are implemented, then optimal material properties are maintained, but energy consumption increases

Engineering Contradiction:

Improvematerial property stabilityVSAvoidpower for temperature control

Core Design Contradiction:

ReliabilityVSUse of energy by moving object

Solution Approach 1:

The patent employs phase change materials that utilize phase transitions to passively regulate temperature by absorbing or releasing latent heat. This passive phase change mechanism maintains material property stability with minimal energy input compared to active heating/cooling systems

Inventive Principle:

Principle #36Phase transitions

Solution Approach 2:

The temperature regulation system incorporates self-regulating mechanisms where temperature sensors automatically trigger heating or cooling actions only when needed, and phase change materials passively compensate for temperature variations. This self-service approach minimizes continuous energy consumption while maintaining optimal material properties

Inventive Principle:

Principle #25Self-service
