Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Conventional articles of protective clothing for firefighters do not adequately ensure visibility in emergency situations, as flashlights can be displaced, reducing visibility for the wearer and rescue personnel.

Innovation Solution

Integration of a light source within the clothing, such as a light-emitting diode (LED) or strobe light, encased in a housing with a protective shield and power source, providing enhanced visibility through a light-permeable and protective shield that meets NFPA 1971-8.6 standards for heat and water resistance, and is removable for repair or replacement.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Illumination intensity

If a flashlight is carried by the firefighter, then visibility can be improved, but the flashlight can be displaced in emergency situations, significantly decreasing visibility

Engineering Contradiction:

ImprovevisibilityVSAvoidvisibility reliability

Core Design Contradiction:

Illumination intensityVSReliability

Solution Approach 1:

The patent merges the light source with the protective clothing by integrating the housing containing the light source into the clothing structure. This integration ensures the light source remains fixed and cannot be displaced during emergency situations, while still providing the necessary visibility function.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The protective clothing serves multiple functions: it provides protective properties (fire resistance, water resistance, impact resistance) and simultaneously serves as a mounting structure for the light source. This multi-functionality eliminates the need for separate flashlight carrying and ensures the light source remains reliably attached.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Reliability

If a light source is integrated within the protective clothing, then visibility reliability is improved, but the protective properties of the clothing may be compromised

Engineering Contradiction:

Improvevisibility reliabilityVSAvoidprotective properties

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent segments the light source system into a separate housing that is integrated into the protective clothing. This housing contains the light source and power source, isolating these components from the main protective clothing while maintaining the protective properties of the clothing itself.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The housing acts as an intermediary structure between the light source and the protective clothing. It provides a mounting structure for the light source while the shield maintains the protective barrier properties of the clothing, ensuring both visibility reliability and protective properties are maintained.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Reliability

If a shield is placed over the light source, then the light source is protected, but the shield may reduce light output

Engineering Contradiction:

Improvelight source protectionVSAvoidlight output

Core Design Contradiction:

ReliabilityVSIllumination intensity

Solution Approach 1:

The shield is designed with specific optical properties (transparency, translucence, or opacity) that allow it to protect the light source while maintaining appropriate light output. The shield's optical characteristics are selected to balance protection with visibility requirements.

Inventive Principle:

Principle #32Color changes

Solution Approach 2:

The shield's properties (transparency, translucence, opacity) are carefully selected and adjusted to achieve the right balance between protecting the light source and allowing sufficient light output. This parameter optimization ensures the shield fulfills its protective function without excessively reducing light performance.

Inventive Principle:

Principle #35Parameter changes
