Solution Overview

Problem

Hoses used in dark environments, such as firefighting and street applications, are difficult to distinguish and may become disoriented due to darkness, high humidity, temperature, and exposure to toxic gases, necessitating a hose that is both illuminated and resistant to harsh conditions.

Innovation Solution

A hose design featuring a light emitting element arranged between an inner and outer layer, with the light emitting element protected from the fluid and external environment, and powered through a coupling element that connects to a fluid supply source, allowing for automatic activation without additional action.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Illumination intensity

If a light emitting element is integrated into the hose to improve visibility in dark environments, then the visibility is improved, but the light emitting element is exposed to damage from liquid and environmental conditions

Engineering Contradiction:
ImprovevisibilityVSAvoidprotection from liquid and environment
Core Design Contradiction:
Illumination intensityVSReliability

Solution Approach 1:

The light emitting element is nested between the inner layer and outer layer of the hose, with the inner layer protecting it from liquid contact and the outer layer protecting it from environmental conditions. This nested structure allows the light emitting element to be protected while still integrated into the hose system.

Inventive Principle:
Principle #7Nested doll (Nesting)

Solution Approach 2:

The inner and outer layers act as intermediary protective barriers between the light emitting element and the harmful environments (liquid and external conditions). These layers mediate the protection without requiring direct contact or complex sealing mechanisms.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If the light emitting element is protected between inner and outer layers, then protection is improved, but the electrical connection becomes more complex

Engineering Contradiction:
ImproveprotectionVSAvoidelectrical connection
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The electrical connection function is merged with the coupling element that is already present for fluid connection. The coupling element simultaneously provides mechanical coupling and electrical connection through integrated electrical contacts, eliminating the need for separate wiring pathways through the hose layers.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The coupling element is designed to serve multiple functions: mechanical coupling of the hose to the fluid supply source and electrical connection to power the light emitting element. This multi-functionality reduces overall system complexity by combining what could be separate components.

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

3Ease of operation

If automatic activation through coupling element connection is implemented, then ease of operation is improved, but the coupling element design becomes more complex

Engineering Contradiction:
Improveautomatic activationVSAvoidcoupling element design
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The electrical contacts are pre-positioned within the coupling element during manufacturing. When the coupling element is connected to the fluid supply source, the electrical connection is automatically established without requiring any additional actions from the user, such as switching or wiring.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The electrical connection mechanism is combined with the mechanical coupling mechanism in a single integrated component. The coupling element simultaneously performs both mechanical attachment and electrical connection functions, reducing the number of separate components and operations needed.

Inventive Principle:
Principle #5Merging (Combining)
