Solution Overview
Problem
Conventional irradiating devices fail to effectively expose certain areas of the human body, such as the scalp, shoulders, and areas between the arms and legs, to the required amount of radiation for tanning and skin rejuvenation.
Innovation Solution
A device with a semi-cylinder barrel-shaped exposition tunnel and additional radiation sources positioned at acute angles to the longitudinal axis, allowing for targeted irradiation of these areas using LEDs, high-pressure lamps, and low-pressure lamps, along with a restricted space cooling system to manage heat effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If conventional irradiating devices use standard light sources positioned around the user, then the device structure remains simple, but certain body areas (scalp, shoulders, between arms and legs) receive insufficient radiation
Solution Approach 1:
The irradiating device divides the radiation sources into multiple groups positioned at different locations and angles. Standard light sources are arranged to target specific body areas (face, body) while additional sources are strategically positioned to cover previously unirradiated areas like scalp and shoulders, allowing each segment to address specific coverage gaps
Solution Approach 2:
The patent introduces radiation sources positioned at acute angles relative to the longitudinal axis of the device, adding a new dimensional approach to radiation delivery. This angular positioning allows radiation to reach body areas that were previously shadowed or inaccessible from standard radial positioning around the user
2Illumination intensity
If additional radiation sources are added to cover previously unirradiated areas, then radiation coverage is improved, but heat management becomes more challenging
Solution Approach 1:
The patent introduces a cooling system as an intermediary component between the multiple radiation sources and the environment. This cooling system actively manages the thermal output from the additional light sources, preventing excessive heat buildup while allowing the full radiation coverage benefits to be realized
3Manufacturing precision
If the device uses a semi-cylinder barrel-shaped exposition tunnel with additional angled sources, then uniform tanning is achieved, but the device complexity increases
Solution Approach 1:
The patent employs a semi-cylinder barrel-shaped exposition tunnel that provides a curved, encompassing structure around the user. This curved geometry naturally distributes radiation more uniformly across the user's body surfaces, including hard-to-reach areas, while the systematic arrangement of light sources within this curved framework maintains manufacturing feasibility
