Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Retail display cases face limited space for additional point-of-sale advertising, and existing solutions do not effectively utilize the transparent glass to enhance product visibility while allowing for additional advertising without cluttering the area.
Innovation Solution
A wireless transmission system for transparent LCDs is integrated into display cases, with transmitters/receivers positioned below and above the LCD, sandwiched between glass panels, utilizing LEDs for illumination and thermal management to maintain a clear view while allowing for the transmission of advertising materials and data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If transparent LCD is integrated into display case glass to enable additional advertising, then advertising capability is improved, but heat management becomes more difficult
Solution Approach 1:
A thermal interface material is introduced as an intermediary between the wireless transmitter/receiver and the glass panel to improve heat transfer efficiency. This mediator enables effective thermal coupling between the heat-generating electronic component and the glass, allowing the glass to serve as a heat sink while maintaining the advertising functionality of the transparent LCD integration.
2Device complexity
If wireless transmitter/receiver is positioned close to LCD for compact design, then device complexity is reduced, but heat removal efficiency decreases
Solution Approach 1:
The glass panel is designed to serve multiple functions simultaneously: it acts as the substrate for the transparent LCD display, provides structural support for the display case, and functions as a heat sink for thermal management. By making the glass multi-functional, the system achieves compact integration without compromising heat removal efficiency, as the glass's large surface area effectively dissipates heat from the nearby wireless transmitter/receiver.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables effective additional advertising within display cases by maintaining product visibility and efficiently managing heat generated by electronic components, thus enhancing sales awareness without cluttering the retail space.
Implementation Method 1
The mounting plate is preferably bonded to and in thermal communication with the rear glass so that any heat generated by the wireless transmitter/receiver can be transferred to the rear glass for removal by natural or forced convection.
Implementation Method 2
The mounting plate is preferably bonded to and in thermal communication with the rear glass so that any heat generated by the wireless transmitter/receiver can be transferred to the rear glass for removal by natural or forced convection.
Implementation Method 3
The top LEDs are preferably placed in thermal communication with a top plate which is placed in conductive thermal communication with the rear glass. Similarly, the bottom LEDs are preferably placed in thermal communication with a bottom plate which is also placed in conductive thermal communication with the rear glass.
Implementation Method 4
The top and bottom plates permit the heat to spread out and transfer to the rear glass where it can be removed by forced or natural convection.

AI summary
The exemplary embodiments herein provide a sealed transparent LCD assembly having a front and rear glass panel with a spacer positioned between the two panels to provide a sealed cavity containing a liquid crystal display (LCD). A wireless transmitter/receiver may be placed within the sealed cavity to receive image or video data wirelessly. The sealed transparent LCD assembly may be used with a display case which defines a cavity housing a second wireless transmitter/receiver which can push the image or video data to the wireless transmitter/receiver contained within the sealed cavity between the two glass panels.
