Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the display is disposed in the central fixation zone of the contact lens, then the display function is improved, but the reception of ambient light in the main visual area is affected

Engineering Contradiction:

Improvedisplay functionVSAvoidambient light reception

Core Design Contradiction:

Adaptability or versatilityVSIllumination intensity

Solution Approach 1:

The contact lens is divided into distinct functional zones: a central fixation zone for display units and a surrounding main visual area for ambient light reception. This spatial segmentation allows each zone to perform its dedicated function without interfering with the other, resolving the contradiction between display functionality and ambient light reception.

Inventive Principle:

Principle #1Segmentation

2Adaptability or versatility

If the display is directly integrated in the contact lens, then the display capability is improved, but the air permeability of the contact lens deteriorates

Engineering Contradiction:

Improvedisplay capabilityVSAvoidair permeability

Core Design Contradiction:

Adaptability or versatilityVSQuantity of substance

Solution Approach 1:

The contact lens incorporates a porous structure with controlled permeability that allows air and moisture to pass through while accommodating the integrated display units. This porous design enables the lens to maintain adequate air permeability for comfort during extended wear, even with the display integration.

Inventive Principle:

Principle #31Porous materials

3Measurement precision

If the display units are positioned closer to the central axis, then the display resolution is improved, but the air permeability and ambient light reception are affected

Engineering Contradiction:

Improvedisplay resolutionVSAvoidair permeability

Core Design Contradiction:

Measurement precisionVSQuantity of substance

Solution Approach 1:

The contact lens exhibits local quality variations with different regions having distinct properties: the central fixation zone has higher display unit density for improved resolution, while the surrounding areas maintain higher porosity for air permeability. This localized differentiation allows each region to optimize its specific function without compromising overall performance.

Inventive Principle:

Principle #3Local quality
