Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple light emitting elements with different wavelengths are arranged at the same time, then the wavelength variety is improved, but the pitch between light emitting elements increases and uniformity of light deteriorates

Engineering Contradiction:

Improvewavelength varietyVSAvoiduniformity of light

Core Design Contradiction:

Adaptability or versatilityVSStability of the object's composition

Solution Approach 1:

The device segments the light generation function into two independent parts: a single light emitting element that provides the base light, and a separate light conversion layer that generates different wavelengths. This segmentation allows wavelength variety without increasing the pitch between light emitting elements, as only one light emitting element is needed.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The light conversion layer acts as an intermediary between the light emitting element and the treatment target. It converts the base light from the single light emitting element into multiple wavelength components, enabling wavelength variety while maintaining small pitch and light uniformity.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Area of stationary object

If phototherapy is performed on a large area of the human body, then the treatment coverage is improved, but the side effects on healthy areas increase

Engineering Contradiction:

Improvetreatment coverageVSAvoidside effects on healthy areas

Core Design Contradiction:

Area of stationary objectVSObject-affected harmful factors

Solution Approach 1:

The adjustable structure enables local quality control by allowing the light penetrating area to be dynamically adjusted to match the specific shape and size of the affected area. This ensures that phototherapy is delivered precisely where needed, improving treatment coverage of affected areas while avoiding healthy tissues.

Inventive Principle:

Principle #3Local quality

Solution Approach 2:

The adjustable structure provides dynamic control over the light penetrating area, allowing real-time adaptation to different affected area shapes and sizes. This dynamic adjustment capability enables precise targeting of affected areas while excluding healthy areas from treatment.

Inventive Principle:

Principle #15Dynamics

3Measurement precision

If phototherapy is performed on a specific area with multiple laser points, then the target precision is improved, but the uniformity and time consumption deteriorate

Engineering Contradiction:

Improvetarget precisionVSAvoiduniformity

Core Design Contradiction:

Measurement precisionVSStability of the object's composition

Solution Approach 1:

The light conversion layer copies the base light from the single light emitting element multiple times at different wavelength conversions, creating a uniform light distribution across the light penetrating area. This copying mechanism achieves target precision through the adjustable structure while maintaining uniformity, avoiding the need for multiple separate laser points.

Inventive Principle:

Principle #26Copying

4Device complexity

If the wavelength of light is limited to a few specific wavelengths, then the device complexity is reduced, but the phototherapy efficacy deteriorates

Engineering Contradiction:

Improvedevice complexityVSAvoidphototherapy efficacy

Core Design Contradiction:

Device complexityVSReliability

Solution Approach 1:

The light conversion layer changes the wavelength parameter of the base light through material conversion, generating multiple wavelength components from a single light emitting element. This parameter change approach improves phototherapy efficacy by providing wavelength variety while keeping the device simple with only one light emitting element.

Inventive Principle:

Principle #35Parameter changes
