Solution Overview
Problem
Current advertising displays, particularly those using high-intensity discharge lighting, are costly to maintain and operate, lacking versatility and efficiency, with LEDs primarily used as primary lighting rather than to create interactive or holographic effects on images.
Innovation Solution
A color changing display system incorporating a light source, controller, and combined printed images that react to different light colors, producing a moving, holographic effect by using RGB-LEDs to transition between colors, which can be applied to various materials like bottles, fabrics, or substrates for energy-efficient and interactive displays.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If high-intensity discharge lighting is used to illuminate displays, then the displays are brightly illuminated and visible, but the operational costs and energy consumption increase significantly
Solution Approach 1:
The patent changes the fundamental parameter of light emission from high-intensity discharge to LED technology, which operates at lower energy levels while maintaining sufficient illumination. This parameter change resolves the contradiction by achieving the required brightness with significantly reduced energy consumption.
Solution Approach 2:
The patent substitutes the mechanical high-intensity discharge lighting system with an LED-based optical system that uses color filtering and light modulation. This substitution replaces the energy-intensive discharge mechanism with a more efficient solid-state lighting approach.
2Ease of manufacture
If traditional static or mechanical signage is used for displays, then the displays are simpler and less expensive to manufacture, but they lack versatility and interactivity
Solution Approach 1:
The patent introduces dynamic color changing capabilities through LED control, allowing the display to transition between different colors and states. This dynamic element adds versatility while maintaining the simplicity of the physical structure, resolving the contradiction between ease of manufacture and adaptability.
Solution Approach 2:
The patent creates a multi-functional display system that can serve both as a static sign and as an interactive, color-changing display. The same physical structure supports multiple functions through electronic control, achieving versatility without complicating the manufacturing process.
3Use of energy by moving object
If LEDs are used as primary lighting in displays, then energy efficiency is improved, but the ability to create interactive and holographic effects on images is limited
Solution Approach 1:
The patent introduces color filters and light-modulating materials as intermediaries between the LED light source and the display images. These intermediaries enable interactive and holographic effects by selectively transmitting or blocking light based on color, thereby expanding the LED system's capabilities without sacrificing energy efficiency.
Solution Approach 2:
The patent utilizes color changes in the LED light source and corresponding color filters in the displayed images to create interactive effects. By coordinating color transitions between the light source and the image elements, the system achieves holographic and interactive capabilities while maintaining LED energy efficiency.
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
The system creates an energy-efficient, interactive, and holographic display experience by smoothly transitioning between colors, enhancing the appearance of images and reducing operational costs, offering a versatile alternative to traditional displays.
Implementation Method 1
the use of energy efficient light-emitting diodes (LEDs) as LEDs have a high lumen output and a distinctly low power consumption
Implementation Method 2
The light source is for producing different light colors... the light source projects the different light colors onto the body such that the different light colors are transmitted through the light-transmitting material of the body
Implementation Method 3
The images are different colors. Each of the different color images reacts with a respective color of the different light colors such that an appearance of the combined printed image changes gradually
Data Source
AI summary
A color changing display system includes a fabric body, a light source connected to the fabric body, a controller electrically connected to the light source, and a combined printed image comprising two or more images printed in a single layer on the fabric body. The light source is for producing different light colors. The controller is configured to control the light source to provide a smooth transition between the different light colors. The images are different colors. Each of the different color images reacts with a respective color of the different light colors such that an appearance of the combined printed image changes gradually from a first display image having one particular shape into a second display image having a second particular shape in response to the different light colors interacting with the combined printed image to produce a moving, seemingly holographic effect.
