Lithophane Display Unit With Integrated Light Source
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for visualizing lithophanes require natural daylight or artificial light sources for image visibility, which can be inconvenient, especially at night or in dark environments, as users need to position light sources or hold the lithophane for illumination.
Innovation Solution
A display unit with a built-in light source, adjustable brightness, and color options, featuring a stand piece with a roughened surface for even light diffusion, allowing for image viewing using both natural and artificial light without manual handling of the lithophane.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If natural daylight or artificial light sources are used for backlighting, then the lithophane image becomes visible, but the user must manually position the light source or hold the lithophane, which is inconvenient
Solution Approach 1:
The display unit incorporates a built-in light source that automatically illuminates the lithophane without requiring manual positioning of external light sources. The system serves itself by integrating the illumination function directly into the display structure, eliminating the need for users to hold or position the lithophane manually.
Solution Approach 2:
The patent combines the light source with the display unit structure, merging the illumination function with the display function. This integration allows the lithophane to be viewed without separate manual lighting operations, as the light source is permanently integrated into the display assembly.
2Illumination intensity
If artificial light sources are used at night or in darkened rooms, then the lithophane image can be viewed, but the user needs to position light sources which is cumbersome
Solution Approach 1:
The display unit automatically provides illumination in dark environments through its integrated light source, eliminating the need for users to position external artificial light sources. The system self-regulates the lighting condition for optimal lithophane visibility without user intervention.
3Illumination intensity
If the lithophane is held up to light for viewing, then the image is visible, but the lithophane is subjected to manual handling which may compromise its integrity
Solution Approach 1:
The display unit provides a stable, fixed positioning system with integrated illumination that eliminates the need to hold the lithophane manually. The lithophane is securely positioned within the display unit structure, protecting it from handling damage while maintaining optimal viewing conditions.
Solution Approach 2:
The display unit acts as an intermediary structure that holds the lithophane in place and provides illumination simultaneously. This intermediary system protects the lithophane from direct manual handling while ensuring proper lighting for viewing.
4Ease of operation
If a built-in light source is integrated into the display unit, then manual positioning is eliminated, but the device structure becomes more complex
Solution Approach 1:
The light source is merged with the display unit structure, combining illumination and display functions into a single integrated system. This merging approach, while adding structural elements, provides automatic illumination functionality that simplifies user operation.
