Monocular Light Source Positioning for Unobstructed Vision
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing light therapy devices for conditions like Seasonal Affective Disorder and Jet Lag often interfere with normal activities due to their fixed positioning requirements, limiting user mobility and comfort.
Innovation Solution
A monocular photoneuronic device with a support member held on the head, featuring a bendable light source extension that can be adjusted to position a cyan LED light source between 420-520 nm wavelength in front of or above one eye, allowing for comfortable and effective light stimulation without obstructing the other eye's view.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a fixed positioning light therapy device is used, then light therapy effectiveness is improved, but user mobility and comfort are reduced
Solution Approach 1:
The patent applies the dynamics principle by making the light source position adjustable and movable. The light source can be repositioned along the support member and adjusted to different angles, allowing the device to adapt to various user positions and activities while maintaining effective light therapy delivery.
Solution Approach 2:
The patent changes the positional parameters of the light source to resolve the contradiction. The light source can be adjusted in terms of position, angle, and orientation along the support member, enabling effective therapy while allowing user mobility and comfort during daily activities.
2Reliability
If a monocular light source is positioned in front of one eye, then light therapy effectiveness is improved, but obstruction of the other eye's view occurs
Solution Approach 1:
The patent segments the light therapy function to be delivered to only one eye at a time. By positioning the light source in front of or above one eye while leaving the other eye completely clear, the device provides effective monocular stimulation without obstructing the user's overall field of view or visual comfort.
3Stability of the object's composition
If a rigid support structure is used, then structural stability is improved, but device adaptability to different positions and activities is reduced
Solution Approach 1:
The patent employs a flexible support member that can bend and adapt to different positions and orientations. This flexible structure maintains sufficient stability to support the light source while allowing adjustment to various angles and positions, enabling adaptability to different user activities and preferences.
Solution Approach 2:
The support member is designed with dynamic characteristics, allowing it to be bent and repositioned while maintaining structural integrity. This enables the device to adapt to different user positions and activities without compromising the stability required for effective light therapy delivery.
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
Enables light therapy while allowing users to move freely and conduct daily activities without interference, providing sufficient light intensity to stimulate a photoendocrine response without obstructing the principal field of view.
Implementation Method 1
The light source may be a single narrow beam cyan LED mounted within a reflector body
Implementation Method 2
light emitted by the light source is preferably of a wavelength between approximately 420 mm and 520 mm and of sufficient intensity to effectively stimulate a photoendocrine response
Implementation Method 3
single narrow beam cyan LED mounted within a reflector body, oriented so as to direct light into the one eye
Data Source
AI summary
A monocular light source positioning device includes a support member which held on the head of a user to hold an elongated readily bendable but self supporting element having a light source effective to stimulate a photo-endocrine response attached at a free end thereof positioned over or in front of only one eye of the person to provide a method of stimulating a photoendocrine response without interfering with the principal field of view of the user.
