Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing gaming chips face challenges in authenticating their legitimacy due to the difficulty in visually confirming and maintaining the integrity of internal printing, which can be easily peeled or faded, and existing technologies rely solely on surface markings that can be counterfeited.
Innovation Solution
A gaming chip with a multilayer structure using infrared absorbing material for internal printing, combined with a normal camera and infrared camera system to authenticate the chip based on both surface and internal markings, along with an RF tag for additional verification.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If surface markings are used for authentication, then the authentication process is simple, but the markings can be easily counterfeited and visually confirmed
Solution Approach 1:
The patent introduces infrared absorption characteristics as a new dimension for authentication. Instead of relying solely on visible surface markings, the gaming chip incorporates infrared absorbing material that creates specific patterns detectable only in the infrared spectrum. This adds a hidden layer of authentication that is invisible to the human eye but verifiable by inspection devices, thereby enhancing security without complicating the visible appearance of the chip.
Solution Approach 2:
The patent introduces an infrared absorbing material as an intermediary element within the gaming chip. This material acts as a mediator between the chip's identity and the inspection device, enabling authentication through infrared pattern recognition. The intermediary allows the system to verify authenticity without exposing sensitive information visually, resolving the contradiction between simple verification and security.
2Reliability
If internal printing with infrared absorbing material is used, then counterfeiting becomes more difficult, but the printing is not visually discernible and requires specialized equipment
Solution Approach 1:
The patent shifts the authentication domain from the visible spectrum to the infrared spectrum. By embedding infrared absorbing material that creates detectable patterns in the infrared range, the system makes authentication information invisible to human eyes but accessible to inspection devices equipped with infrared sensors. This dimensional shift simultaneously enhances counterfeiting resistance and manages detection complexity by directing it to specialized equipment.
Solution Approach 2:
The patent extracts the authentication information from the visible domain and places it in the infrared domain. The infrared absorbing material contains hidden patterns that are extracted and detected only under infrared illumination, separating the authentication function from visual appearance. This extraction allows the chip to maintain normal visual characteristics while incorporating enhanced security features.
3Stability of the object's composition
If multilayer structure with thermocompression bonding is used, then the chip structure is more stable, but the manufacturing process becomes more complex
Solution Approach 1:
The patent divides the gaming chip into multiple functional layers, each serving a specific purpose. The multilayer structure includes separate layers for visual appearance, infrared absorption, and structural integrity. By segmenting the chip design, the patent enables independent optimization of each layer's properties and simplifies the integration of different materials and functions, making the complex manufacturing process more manageable through modular construction.
Solution Approach 2:
The patent employs composite material construction by combining different materials with complementary properties in a multilayer structure. Each layer uses materials optimized for its specific function, such as transparent plastics for visual layers and infrared absorbing materials for security layers. The thermocompression bonding process joins these composite layers into a stable integrated structure, balancing manufacturing complexity with structural stability.

AI summary
A management system includes a recording device recording an image of a gaming chip and an inspection device determining a type and authenticity of the gaming chip. The gaming chip has a multilayer structure in which both sides of a colored layer are sandwiched between light color layers, surface printing representing a type of the gaming chip is performed on outer sides of the light color layers, and an authenticity recognition mark is printed on the colored layer of an inside of the light color layers by an infrared absorbing material. A visible light camera photographs a visible light image of the surface printing, and an infrared light camera photographs an infrared image of the internal printing. The inspection device determines the type and authenticity of the gaming chip using the visible light image and the infrared image.
