Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If UV LEDs are arranged in a pattern on a surface in close proximity to the receptacle and moved over the receptacle to directly illuminate it, then the system can be simpler without complex optics, but the illumination uniformity becomes sub-ideal with lower intensity at edges and inhomogeneities from panning movement

Engineering Contradiction:
Improveillumination system complexityVSAvoidUV radiation uniformity
Core Design Contradiction:
Device complexityVSIllumination intensity

Solution Approach 1:

An illumination optics assembly is introduced as an intermediary component between the UV radiation source and the receptacle. This assembly includes optical elements (lenses, mirrors, or light guides) that redistribute and homogenize the UV radiation across the receptacle surface, eliminating the direct illumination approach while maintaining system simplicity through integrated optical design

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The illumination system changes the spatial distribution parameters of UV radiation by using optical elements with specific geometries (e.g., diffusers, homogenizing lenses) that transform the non-uniform radiation pattern from direct LED illumination into a homogeneous distribution across the entire receptacle surface

Inventive Principle:
Principle #35Parameter changes

2Device complexity

If UV LEDs are moved over the receptacle to directly illuminate it, then the system structure can be simpler, but light wastage increases as considerable amount of light is lost and not arriving at the sample

Engineering Contradiction:
Improveillumination system structureVSAvoidUV light wastage
Core Design Contradiction:
Device complexityVSLoss of energy

Solution Approach 1:

The mechanical panning movement system is replaced with a stationary illumination optics assembly that uses optical principles (refraction, reflection, total internal reflection) to redirect and concentrate UV light onto the receptacle, eliminating the need for moving parts while improving light delivery efficiency

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The illumination optics assembly acts as an intermediary that captures and redirects UV radiation that would otherwise be wasted, using optical elements to guide light from the LED source through a controlled path to the receptacle, thereby reducing light loss without requiring complex mechanical positioning systems

Inventive Principle:
Principle #24Intermediary (Mediator)

3Device complexity

If UV LEDs are arranged in a pattern on a surface and moved over the receptacle, then the system can avoid complex optics, but panning movement causes inhomogeneities in illumination

Engineering Contradiction:
Improveoptical system complexityVSAvoidillumination homogeneity
Core Design Contradiction:
Device complexityVSStability of the object's composition

Solution Approach 1:

The illumination optics assembly serves as a stable intermediary that establishes a fixed, controlled optical path from the UV source to the receptacle. This eliminates the variability introduced by panning movement while maintaining system simplicity through integrated optical design without requiring complex active control mechanisms

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The system changes the illumination parameters by using optical elements with specific geometric configurations (e.g., angled facets, diffuser patterns) that ensure uniform light distribution across the receptacle surface, eliminating the inhomogeneities caused by mechanical movement while keeping the overall system design simple

Inventive Principle:
Principle #35Parameter changes
