Transparent Cooler Display With Distance-Based Visibility Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional transparent display panels in coolers cannot effectively provide information to users located far away while maintaining transparency for product visibility when close, as they lack control over transparency based on user distance.
Innovation Solution
A cooler with a transparent display assembly that includes a dispersion panel and a light source, where the transparency is controlled by a proximity sensor to adjust light irradiation based on user distance, allowing selective visibility of products or information depending on the user's proximity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a transparent display panel is used in the cooler door, then product visibility is improved when users are close, but information visibility to users far away deteriorates
Solution Approach 1:
The display panel dynamically changes its transparency state based on user proximity detection. When a user approaches within a predetermined distance, the panel switches to a transparent state for product visibility. When the user is far away, the panel switches to an opaque state for information visibility, resolving the contradiction between the two visibility requirements through dynamic adaptation.
Solution Approach 2:
The transparency parameter of the display panel is changed based on user distance. The panel transitions between transparent and opaque states by controlling the transparency parameter, allowing optimal visibility conditions for different user positions - transparent when close for product viewing, opaque when far for information viewing.
2Illumination intensity
If the display panel is made opaque to improve information visibility, then information can be seen clearly, but product visibility through the panel is lost
Solution Approach 1:
The display panel dynamically adjusts its transparency based on user proximity rather than being fixed opaque. This dynamic behavior ensures that product visibility is maintained when needed (when users are close) while information visibility is optimized when users are far away, eliminating the need to sacrifice product visibility for information display.
3Reliability
If the display panel is made transparent to maintain product visibility, then users can see products clearly, but information visibility to users far away deteriorates
Solution Approach 1:
The display panel switches between transparent and opaque states dynamically based on user distance. When users are far away, the panel becomes opaque to enhance information visibility. When users approach, the panel becomes transparent to maintain product visibility, thus resolving the contradiction through temporal and spatial adaptation.
Solution Approach 2:
The transparency parameter of the display panel is adjusted based on user proximity. The control unit changes the transparency parameter from transparent to opaque state when users are detected at a distance, optimizing information visibility without permanently sacrificing product visibility capability.
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
Optimizes the display by ensuring that information is clearly visible to users far away to stimulate purchasing, while allowing clear product visibility when close, thus enhancing user experience and sales efficiency.
Implementation Method 1
a dispersion panel arranged at a rear of the transparent display panel and configured to scatter light, which is incident upon a side of the dispersion panel, therein
Implementation Method 2
a light source that irradiates light from the side of the dispersion panel to the inside of the dispersion panel

AI summary
A cooler (1) having a transparent display is provided. The cooler (1) may include a body (10) forming a predetermined space (11) configured to receive products therein; a cooling unit (15) or device installed in the body (10) and configured to supply cooled air into the space (11); a door (20) installed in or on the body (10) to open and close the space (11); and a transparent display assembly (100) installed in the door (20) and configured to provide predetermined information related to the products to a user. The transparent display assembly (100) may include a transparent display panel (110), a dispersion panel (120) arranged at a rear of the transparent display panel (110) and configured to scatter light, which is incident upon a side of the dispersion panel (120), and a light source (130) that irradiates light from the side of the dispersion panel (120) to an inside of the dispersion panel (120). A transparency of the dispersion panel (120) may be controlled depending on a distance between a user and the cooler (1) to allow the user to selectively see the products.
