Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Illumination intensity

If a transparent display screen concentrates pixels to create transparent areas, then transparency is improved, but the effective area of pixels becomes small and visibility deteriorates

Engineering Contradiction:

ImprovevisibilityVSAvoideffective area of pixels

Core Design Contradiction:

Illumination intensityVSArea of stationary object

Solution Approach 1:

Each pixel unit is segmented into multiple sub-pixels (red, green, blue) arranged around a transparent light transmission portion. This segmentation allows the pixel unit to maintain a larger overall area while still providing transparent regions, thereby improving both visibility and effective pixel area simultaneously

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The sub-pixels are arranged in a two-dimensional pattern around the transparent portion rather than in a simple linear concentration. This dimensional arrangement increases the effective light-emitting area while maintaining transparency, resolving the contradiction between pixel effective area and visibility

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

2Illumination intensity

If brightness is intensified to improve interpretation ability, then visibility is improved, but dazzling effect occurs

Engineering Contradiction:

Improveinterpretation abilityVSAvoiddazzling effect

Core Design Contradiction:

Illumination intensityVSObject-affected harmful factors

Solution Approach 1:

Different regions of the display panel have different light transmission characteristics. The transparent light transmission portions allow high light transmission for visibility, while the sub-pixel regions provide localized light emission. This local quality differentiation enables moderate overall brightness while maintaining good interpretation ability without causing dazzling effects

Inventive Principle:

Principle #3Local quality

3Illumination intensity

If conventional display panel is used, then display effect is achieved, but line of sight cannot penetrate and visual range is reduced

Engineering Contradiction:

Improvedisplay effectVSAvoidvisible area

Core Design Contradiction:

Illumination intensityVSArea of stationary object

Solution Approach 1:

The invention merges the light-emitting function of conventional displays with the light-transmitting function of transparent materials. Each pixel unit combines light-emitting sub-pixels with transparent light transmission portions, creating a hybrid structure that achieves both display effect and line of sight penetration, thereby expanding the user's visual range

Inventive Principle:

Principle #5Merging (Combining)

4Ease of operation

If projection display screen is used, then display function is achieved, but reflection and uneven projection surface cause poor visibility

Engineering Contradiction:

Improvedisplay functionVSAvoidvisibility

Core Design Contradiction:

Ease of operationVSIllumination intensity

Solution Approach 1:

The invention replaces the projection-based mechanical system with a direct light-emitting system. Instead of projecting images onto a surface that causes reflection and deformation issues, the display panel directly emits light from sub-pixels within each pixel unit. This substitution eliminates reflection problems and uneven projection effects, significantly improving visibility

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)
