Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing display mediums face challenges in maintaining visibility of content due to the influence of the color of protrusion members on the displayed colors, limiting the selection of content that can be displayed.

Innovation Solution

A display medium is designed with a planar member segmented into unit cells and sub-cells, featuring a protrusion member with a light-shielding surface tinted in achromatic colors through additive color mixing, allowing for the display of arbitrary content without color interference.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If the protrusion member is made with a monochromatic color, then the manufacturing process is simple, but the visibility of the content is reduced due to color interference

Engineering Contradiction:

Improvemanufacturing simplicityVSAvoidcontent visibility

Core Design Contradiction:

Ease of manufactureVSReliability

Solution Approach 1:

The protrusion member is divided into multiple regions, each with different color characteristics. This segmentation allows the protrusion member to have multiple functions: maintaining structural simplicity while reducing color interference with the displayed content through strategic color distribution across different regions.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Different regions of the protrusion member are assigned different color properties based on their specific functions. The light-shielding surface uses one color configuration while other regions use different configurations, optimizing both manufacturing ease and content visibility by applying quality locally rather than uniformly.

Inventive Principle:

Principle #3Local quality

2Ease of manufacture

If the protrusion member color is made uniform, then the manufacturing process is simple, but the selection of displayable content is limited

Engineering Contradiction:

Improvemanufacturing process simplicityVSAvoidcontent selection range

Core Design Contradiction:

Ease of manufactureVSAdaptability or versatility

Solution Approach 1:

The protrusion member is divided into multiple regions with different color characteristics, enabling it to support a wider variety of content types and color schemes while maintaining a relatively simple manufacturing process through standardized regional patterns.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The multi-colored protrusion member design creates a universal solution that can accommodate various content selections and display requirements. By incorporating multiple color regions, the protrusion member becomes adaptable to different content types without requiring complete redesign for each content scenario.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Ease of manufacture

If the protrusion member is tinted with a single color, then the manufacturing cost is low, but the content visibility is affected by the protrusion member's color shade

Engineering Contradiction:

Improvemanufacturing costVSAvoidcontent visibility

Core Design Contradiction:

Ease of manufactureVSReliability

Solution Approach 1:

The protrusion member is segmented into multiple color regions, which can be implemented using cost-effective methods such as selective inkjet printing or regional coloring during the molding process. This segmentation reduces color interference with content while maintaining reasonable manufacturing costs through efficient production techniques.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Color is applied locally to specific regions of the protrusion member rather than uniformly across the entire structure. This approach reduces the overall amount of expensive multi-color material or processing required, maintaining cost-effectiveness while improving content visibility through strategic color placement in critical regions.

Inventive Principle:

Principle #3Local quality
