Solution Overview

Problem

There is a need in dentistry for a mouth guard that can apply light therapy to reduce viruses and bacteria in a patient's mouth while preventing inadvertent exposure to harmful blue or ultra-violet light, which can be harmful to the eyes of both the patient and the practitioner.

Innovation Solution

A mouth guard made of flexible material with a circuit board containing light-emitting diodes (LEDs) that generates light and an electronic circuit to control the voltage applied to the LEDs, ensuring safe application by initiating a timer only when properly positioned, thus avoiding eye exposure to harmful light.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If blue or ultra-violet light is applied to the patient's mouth to reduce virus and bacteria, then the sterilization effect is improved, but the risk of eye damage to both patient and practitioner increases

Engineering Contradiction:
Improvesterilization effectVSAvoideye damage risk
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The mouth guard is divided into distinct functional zones: a light-transmissive region that allows therapeutic light to pass through to the oral cavity, and an light-blocking region that prevents harmful light from reaching the patient's eyes. This segmentation enables simultaneous achievement of sterilization and eye protection without requiring separate devices.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The mouth guard acts as an intermediary device between the light source and the patient's mouth/eyes. It selectively transmits beneficial light wavelengths to the oral cavity while blocking harmful wavelengths from reaching the eyes, thus mediating the interaction between light therapy and the patient.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If light therapy is applied continuously to maximize sterilization, then the effectiveness is improved, but the exposure time to harmful light increases

Engineering Contradiction:
Improvesterilization effectivenessVSAvoidlight exposure duration
Core Design Contradiction:
ReliabilityVSDuration of action of moving object

Solution Approach 1:

The mouth guard segments the light spectrum into transmissive and blocking regions, allowing continuous light application while protecting the eyes throughout the entire treatment duration, thus eliminating the need to limit treatment time for safety reasons.

Inventive Principle:
Principle #1Segmentation

3Object-affected harmful factors

If eye protection measures are added to the light therapy system, then the safety is improved, but the device complexity increases

Engineering Contradiction:
Improveeye safetyVSAvoidsystem complexity
Core Design Contradiction:
Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The light-blocking function is merged into the mouth guard structure itself rather than being a separate component. The mouth guard combines light transmission, light blocking, and patient positioning functions into a single integrated device, simplifying the overall system while maintaining eye protection.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The mouth guard serves multiple functions simultaneously: it protects the patient's eyes from harmful light, allows therapeutic light to reach the oral cavity, and can be positioned to ensure proper light delivery. This multi-functionality eliminates the need for separate eye protection devices.

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