Solution Overview

Problem

Existing tanning and phototherapy systems lack the ability to dynamically adjust UV light emission based on individual skin conditions, potentially leading to suboptimal tanning results and increased risk of skin damage from UV exposure.

Innovation Solution

A tanning or phototherapy system incorporating a light source with UV light emitting elements of different peak wavelengths, a controller to adjust luminous characteristics, and a sensor to monitor both light source and user skin conditions, allowing for real-time adjustment of UV intensity and spectrum to optimize tanning effects while minimizing harm.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If UV light intensity is increased to enhance tanning effects, then tanning efficiency is improved, but skin damage risk increases

Engineering Contradiction:
Improvetanning efficiencyVSAvoidskin damage risk
Core Design Contradiction:
ProductivityVSObject-affected harmful factors

Solution Approach 1:

The system dynamically changes UV light parameters (wavelength distribution and intensity) based on real-time skin condition monitoring. The controller adjusts the ratio of UVA to UVB light and modulates intensity levels according to sensed melanin content and skin response, enabling efficient tanning while preventing damage through continuous parameter optimization

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The sensor continuously monitors skin conditions (melanin content, skin response) and feeds this information back to the controller. The controller uses this feedback to automatically adjust UV light emission in real-time, creating a closed-loop control system that enhances tanning efficiency while preventing skin damage through adaptive response to actual skin state

Inventive Principle:
Principle #23Feedback

2Productivity

If UV light wavelength is adjusted to optimize tanning, then tanning effectiveness is improved, but system complexity increases

Engineering Contradiction:
Improvetanning effectivenessVSAvoidsystem complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The light source is segmented into multiple independent light emitting elements, each targeting specific wavelength ranges (UVA1, UVA2, UVB). This segmentation allows the controller to independently adjust each wavelength band based on skin conditions, optimizing tanning effectiveness while managing complexity through modular architecture

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The sensor and controller system serves multiple functions: monitoring melanin content, detecting skin response, determining optimal wavelength ratios, and controlling light emission. This multi-functionality reduces overall system complexity by consolidating multiple subsystems into integrated components

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