Transparent LCD Display Case Door With Integrated Product Lighting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional refrigerated display case doors do not enhance the shopping experience by failing to provide engaging product information or interactive content, limiting customer interaction and product presentation.
Innovation Solution
A display case door assembly featuring a transparent LCD panel between front and rear panels, equipped with a lighting element, light guide, controller, and touch screen, allowing for the presentation of visual and audio media content, user interaction, and improved product visibility while maintaining thermal insulation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a traditional display case door with insulated glass panel is used, then thermal insulation performance is maintained, but product presentation and customer engagement are limited
Solution Approach 1:
The patent combines the LCD display panel with the insulated glass panel into a single integrated door structure. The LCD panel is positioned between the outer and inner glass layers, merging the display function with the thermal insulation function in one unified component, thereby enhancing product presentation without requiring separate additional structures.
Solution Approach 2:
The display case door is designed to perform multiple functions simultaneously: thermal insulation through the insulated glass panel, product information display through the LCD panel, and customer interaction through touch screen capability. This multi-functionality allows a single door structure to address both traditional insulation needs and modern presentation requirements.
2Loss of information
If a transparent LCD panel is added to the display case door, then customer engagement and product information display are enhanced, but manufacturing complexity increases
Solution Approach 1:
The door assembly is divided into distinct functional layers: an outer glass panel for structural integrity and insulation, an LCD panel for information display, and an inner glass panel for additional insulation and protection. This segmentation allows each component to be manufactured and tested separately before assembly, reducing overall manufacturing complexity despite the increased number of components.
3Illumination intensity
If lighting elements and light guides are integrated into the door assembly, then product visibility and display quality are improved, but energy consumption increases
Solution Approach 1:
A light guide component is introduced as an intermediary between the LED lighting element and the display/products. The light guide distributes and directs light from the compact LED source to illuminate both the LCD display and the products behind the glass panel efficiently, maximizing illumination intensity while minimizing the energy input required from the light source.
