Solution Overview

Problem

Existing treatments for seasonal affective disorder, such as light therapy, are inconvenient for patients as they require removing clothing to expose skin to light, which is not feasible in all situations, especially during winter when light exposure is limited.

Innovation Solution

A textile with an active outside surface and an active inside surface comprising optical fibers that capture light and transmit it to the skin, allowing for continuous exposure to light even when the human is covered, using optical fibers that function as a light conductor system.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Illumination intensity

If light therapy is implemented using a lightbox, then light exposure to human skin is improved, but convenience and ease of operation deteriorates as patients must remove clothing and sit at a prescribed distance from the light source

Engineering Contradiction:
Improvelight exposure to skinVSAvoidconvenience of light therapy
Core Design Contradiction:
Illumination intensityVSEase of operation

Solution Approach 1:

The optical fibers are embedded within the textile structure, with the light conductor system nested inside the fabric layers. The outside surface captures light and transmits it through the textile to the inside surface, allowing light exposure while wearing the textile normally without removing clothing or positioning at a specific distance from a light source.

Inventive Principle:
Principle #7Nested doll (Nesting)

Solution Approach 2:

The textile itself acts as an intermediary medium between the external light source and the human skin. The optical fibers within the textile capture light from the environment and transmit it to the inside surface, eliminating the need for direct exposure to artificial lightboxes or removal of clothing.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Illumination intensity

If exposure to sunlight is used for light therapy, then light exposure is improved, but harmful ultraviolet radiation increases the risk of skin cancer

Engineering Contradiction:
Improvelight exposure to skinVSAvoidultraviolet radiation and skin cancer risk
Core Design Contradiction:
Illumination intensityVSObject-affected harmful factors

Solution Approach 1:

The invention extracts only the beneficial visible light component from sunlight while blocking the harmful ultraviolet radiation. The optical fibers transmit light to the inside surface of the textile, and the textile material filters out UV rays, allowing light therapy without the skin cancer risk associated with direct sunlight exposure.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The textile provides different properties to different parts of the light spectrum: it allows beneficial visible light to pass through to the skin while blocking harmful ultraviolet radiation. This selective transmission creates a localized quality that provides light therapy protection without the harmful effects of direct sunlight.

Inventive Principle:
Principle #3Local quality

3Illumination intensity

If artificial light sources are used for light therapy, then light exposure is improved, but the treatment requires removing most clothes and is not feasible in all situations

Engineering Contradiction:
Improvelight exposure to skinVSAvoidfeasibility in different situations
Core Design Contradiction:
Illumination intensityVSAdaptability or versatility

Solution Approach 1:

The textile serves multiple functions: it provides light exposure therapy, maintains clothing coverage for privacy and comfort, and can be worn in various situations including indoor and outdoor environments. The optical fiber system enables light transmission through the textile material itself, making the textile both a protective covering and a light delivery mechanism.

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

Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

Function Achieved in This Case

The textile ensures that human skin is exposed to light in all situations, reducing symptoms of seasonal affective disorder and neurodermatitis by transmitting captured light from the outside surface to the inside surface, which is in contact with the skin, thereby addressing the inconvenience of existing treatments.
