Transparent Showcase Panel Layout to Reduce Product Shadowing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Showcases with traditional glass fronts often suffer from shadowing issues, which can obscure the visibility of products and reduce effective advertisement and display quality.
Innovation Solution
A showcase design featuring a transparent liquid crystal panel at the front, combined with an obliquely arranged light source unit between the front and upper frames, and a downhill bottom surface, which minimizes shadowing by ensuring uniform light distribution and three-dimensional perception.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a traditional glass front is used in the showcase, then the structure is simple and cost-effective, but shadowing occurs that obscures product visibility
Solution Approach 1:
The patent extracts the light source from the traditional front glass structure and relocates it to the upper frame area. By separating the illumination function from the front display surface, the design eliminates shadowing while maintaining structural simplicity. The light source is positioned to illuminate products from above without creating obstructing shadows on the glass front.
Solution Approach 2:
The patent transitions from traditional front-facing illumination to top-down illumination by positioning the light source in the upper frame. This dimensional change in lighting direction eliminates shadowing issues on the front glass while maintaining ease of manufacture. The vertical repositioning of the light source creates a new lighting dimension that resolves the shadowing problem.
2Adaptability or versatility
If a transparent display panel is added to the front frame, then product advertisement effects are improved, but the device complexity increases
Solution Approach 1:
The front frame is designed to serve multiple functions: it provides structural support for the showcase, houses the transparent display panel for product advertisement, and integrates with the overall frame structure. By making the front frame multi-functional, the patent adds advertisement capability without proportionally increasing device complexity.
Solution Approach 2:
The patent merges the display panel integration with the existing front frame structure. Rather than adding a completely separate display system, the transparent display panel is incorporated into the front frame assembly, combining structural and display functions. This integration approach enhances advertisement capability while minimizing the increase in device complexity.
3Ease of manufacture
If the light source is positioned directly in front of the showcase, then illumination is straightforward, but shadowing of products occurs
Solution Approach 1:
The patent employs asymmetric positioning of the light source in the upper frame area, rather than symmetric or direct front positioning. This asymmetric placement optimizes illumination angles to minimize shadowing on products while maintaining ease of manufacture. The light source is positioned at an angle and elevation that prevents direct shadow casting on the displayed items.
Solution Approach 2:
The patent changes the illumination dimension from horizontal (front-facing) to vertical (top-down) by positioning the light source in the upper frame. This dimensional shift in lighting approach eliminates shadowing while keeping the light source positioning straightforward and manufacturable. The vertical illumination angle prevents shadows from blocking product visibility.

AI summary
The present invention relates to a showcase including a transparent display panel. The showcase according to one embodiment of the present invention comprises: frames which form a showroom; a transparent display panel which is disposed on a front surface frame of the frames and displays an image; and a light source unit which provides light to the inside of the showroom, and is disposed to incline in a direction from the front surface frame to an upper surface frame of the frames. Accordingly, the shadow on a product disposed in the showcase can be reduced.
