Innovation Solution
A compact, lightweight illuminated sign with a removable graphic panel and wireless connectivity, featuring a light sensor assembly for automatic luminance adjustment, a control unit for drive voltage management, and a transceiver for central data updates, allowing for dynamic display of various lottery games and messages.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If a compact configuration is used to reduce the size of the lottery sign, then the sign can be conveniently placed in commercial outlets, but the ability to display additional information and accommodate different lottery games is limited
Solution Approach 1:
The lottery sign is divided into multiple independent display regions including a primary jackpot display area, secondary information display area, and graphic image display area. Each region can independently display different lottery game information, allowing the compact sign to accommodate multiple games simultaneously without increasing overall size.
Solution Approach 2:
The control unit is designed to universally control all display regions and accommodate different lottery game types (daily, weekly, instant win games). The system can switch between displaying jackpot values, game rules, and promotional messages, making the compact sign versatile for various lottery games without requiring additional hardware.
2Illumination intensity
If illuminated elements are added to draw attention to the lottery sign, then the sign becomes more visible and attractive, but the device complexity and manufacturing difficulty increase
Solution Approach 1:
A light diffusing panel is introduced as an intermediary between the LED light source and the display regions. The LED strip mounted on the rear surface illuminates the diffusing panel, which then evenly distributes light across all display areas. This intermediary element simplifies the lighting system by using a single LED source instead of multiple individual lights, reducing device complexity while maintaining high illumination intensity and visibility.
3Weight of stationary object
If the lottery sign is designed to be lightweight and thin, then it is easier to install and maintain, but the structural strength and durability may be compromised
Solution Approach 1:
The lottery sign utilizes a thin-walled housing structure with reinforced ribs internally distributed throughout the body. The housing is designed as a lightweight enclosure that provides sufficient structural strength through optimized rib positioning and thickness variation. This allows the sign to be thin and easy to install while maintaining durability during operation and handling.
4Measurement precision
If the jackpot value needs to be updated dynamically to reflect total ticket sales, then the sign accurately reflects current lottery information, but the need for continuous updates increases system complexity
Solution Approach 1:
The mechanical system of manual jackpot updates is replaced with an electronic display system controlled by a control unit. The control unit receives data from a central server via wireless communication and automatically updates the LED display to reflect current jackpot values based on total ticket sales. This substitution eliminates the need for manual intervention while maintaining accurate, real-time display information.
Solution Approach 2:
The system implements a feedback mechanism where the control unit continuously receives jackpot value data from the central server and automatically adjusts the display accordingly. This closed-loop system ensures the displayed jackpot value always accurately reflects the current total ticket sales without requiring manual updates, reducing system complexity while maintaining precision.
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 accurate and attention-grabbing displays of lottery information with automatic luminance adjustment and wireless updates, accommodating multiple games and messages, while being easy to manufacture and maintain.
Implementation Method 1
a light sensor assembly for automatic luminance adjustment
Implementation Method 2
A light illuminating unit, such as a replaceable backlight module, can be mounted on the housing unit to emit light
Implementation Method 3
A reflection section, for example, having an array of reflection sites, is positioned directly against the transparent backlight panel to operatively engage the optical paths of the light rays emitted from the light emitting unit in order to redirect the light from the light emitting unit outward through the transparent backlight panel to a viewer
Data Source
AI summary
An illuminated sign having a housing unit with a frame and one or more light emitting arrays to provide visible indicia and a backlight module for mounting a transparent backlight panel which is held in close contact with a reflection panel and optically positions a light emitting unit to emit light through the backlight panel for emission from the front of the sign. The replaceable sign member accommodates the display of visible indicia and is backlit by the light emitting unit. A light sensor is mounted on the backlight module for measuring ambient light. The light emitting unit can be driven by a signal from the light sensor to automatically set a contrast level of illumination to optimize the information presented by the illuminated sign.
