Engineering Contradiction:

Improveinstallation flexibilityVSAvoidvisual recognition

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

The patent uses a flexible transparent sheet substrate instead of a rigid display structure, allowing the display to be curved or bent to fit non-planar surfaces while maintaining transparency and visual recognition from both sides

Inventive Principle:

Principle #30Flexible shells and thin films

Solution Approach 2:

The patent transitions from a single-sided display to a dual-sided display by utilizing the transparency of the flexible substrate, enabling visual recognition from both the front and back surfaces of the display device

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

2Adaptability or versatility

If a conventional LED display device is used, then images can be displayed, but the display cannot be installed on curved or bent surfaces

Engineering Contradiction:

Improvesurface compatibilityVSAvoidstructural rigidity

Core Design Contradiction:

Adaptability or versatilityVSStability of the object's composition

Solution Approach 1:

The patent employs a flexible transparent sheet substrate that can be curved or bent without breaking, enabling installation on non-planar surfaces such as curved walls or irregular surfaces while maintaining structural integrity

Inventive Principle:

Principle #30Flexible shells and thin films

Solution Approach 2:

The patent introduces flexibility and adaptability to the display structure, allowing it to dynamically conform to different surface geometries rather than requiring a fixed rigid structure

Inventive Principle:

Principle #15Dynamics

3Ease of operation

If a conventional LED display device is used, then images can be displayed on one surface, but the state on the opposite side cannot be known during display

Engineering Contradiction:

Improvevisual accessibilityVSAvoidscene information

Core Design Contradiction:

Ease of operationVSLoss of information

Solution Approach 1:

The patent utilizes the transparency of the flexible substrate to enable visual access from both sides of the display, allowing observers on either side to see through the display to the opposite side while images are being displayed

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

Solution Approach 2:

The patent makes the display surface universally accessible from both sides, allowing the same surface to serve as both a display surface and a transparent window simultaneously

Inventive Principle:

Principle #6Universality (Multi-functionality)
