Solution Overview

Problem

Existing medical devices for polarized light therapy are not suitable for effective illumination of the internal parts of the oral cavity, particularly the inaccessible surface areas of the gums, limiting their effectiveness in treating gingival and periodontal diseases.

Innovation Solution

A handheld medical device with a polarized light emitting arrangement featuring tentacle-shaped treatment consoles of different geometrical designs, allowing precise direction of polarized light to various surface areas within the oral cavity, including inward-facing surfaces, and adjustable for optimal positioning and wavelength control.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Illumination intensity

If existing medical devices for polarized light therapy are used, then the device structure is simple, but the illumination effectiveness on internal oral cavity surfaces is insufficient

Engineering Contradiction:
Improveillumination effectivenessVSAvoiddevice structure
Core Design Contradiction:
Illumination intensityVSDevice complexity

Solution Approach 1:

The device is divided into a handle portion containing the light source and a separate tentacle-shaped treatment console. This segmentation allows the treatment console to be specifically designed with flexible, elongated structures that can reach into the oral cavity and access internal surfaces that are difficult to reach, thereby improving illumination effectiveness without complicating the entire device structure.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The treatment console is designed with tentacle-shaped, flexible structures that can extend and bend to reach into the three-dimensional oral cavity space. This dimensional extension allows the device to illuminate internal surfaces, gums, and periodontal areas that are otherwise inaccessible, significantly improving illumination effectiveness while maintaining a relatively simple overall device structure.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Ease of operation

If a handheld device with flexible treatment console is used, then the accessibility to oral cavity surfaces is improved, but the device complexity increases

Engineering Contradiction:
Improveaccessibility to surfacesVSAvoiddevice structure
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

By separating the device into a handle and a treatment console, the complexity is localized to only the necessary components. The treatment console can be designed with flexible, tentacle-shaped structures for easy manipulation and access to difficult-to-reach areas, while the handle remains a simple, ergonomic housing containing the light source and control electronics.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The treatment console incorporates flexible materials and thin-film structures that allow it to bend and conform to the contours of the oral cavity. This flexibility enables the device to access and illuminate various surface areas including inward-facing gum surfaces, without requiring a complex mechanical articulation system.

Inventive Principle:
Principle #30Flexible shells and thin films

3Reliability

If polarized light is used for treatment, then the healing and anti-inflammatory effects are enhanced, but the requirement for precise wavelength control increases

Engineering Contradiction:
Improvehealing effectVSAvoidwavelength control
Core Design Contradiction:
ReliabilityVSManufacturing precision

Solution Approach 1:

The device incorporates a polarizer optical unit that can be adjusted to change the polarization state and wavelength of the light emitted. This allows precise control over the light parameters to optimize the healing and anti-inflammatory effects on different oral tissues, while the adjustments can be made during use without requiring extremely tight manufacturing tolerances on the light source itself.

Inventive Principle:
Principle #35Parameter changes
