Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electronic cards lack a mechanism to remind users of ongoing transactions, making them vulnerable to data theft during or after transactions.
Innovation Solution
An electronic card capable of light-emitting display, comprising a card body, an electrical control module, a light-emitting module, and a light-guiding module, which emits light to indicate data exchange and enhances display brightness through an oblique refraction portion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional contact type or non-contact type cards are used, then the card structure is simple, but the card lacks any mechanism for giving a reminder to consumers about transaction status
Solution Approach 1:
The patent combines multiple functional modules (control module, light-emitting module, light-guiding module) into a single card body structure. The control module integrates circuit control carrier plate with non-contact type radio-frequency antenna or contact type communication chip, while the light-emitting module and light-guiding module work together to provide visual feedback, merging these components into a unified card system that provides both data communication and status indication functions.
Solution Approach 2:
The card body serves multiple functions: it acts as a data storage medium (through RFID tag or chip), a communication interface (via antenna or chip), and a visual feedback device (through light-emitting and light-guiding modules). The border portion of the card body simultaneously serves as both a structural element and a display medium for transaction status information, demonstrating multi-functionality that resolves the contradiction between reliability improvement and structural complexity.
2Loss of information
If no light-emitting mechanism is added, then the card structure remains simple, but the consumer cannot determine whether the transaction is being carried out or finished
Solution Approach 1:
The light-guiding module acts as an intermediary between the light-emitting module and the border portion display area. It receives light from the light-emitting module and guides it to illuminate the border portion, thereby mediating the transmission of transaction status information visually. This intermediary mechanism enables effective information communication without requiring direct integration of all components.
Solution Approach 2:
The patent utilizes light emission and guidance to create visual changes in the border portion of the card body during transactions. The light-emitting module generates light that is guided to illuminate the border portion, creating visible color or brightness changes that indicate transaction status, thereby converting electrical signals into optical information for user perception.
3Reliability
If the card provides visual feedback during data exchange, then user awareness and security are enhanced, but the card structure becomes more complex with additional modules
Solution Approach 1:
The patent implements a nested structure where the light-emitting module and light-guiding module are integrated within the card body. The control module is disposed in the card body and contains the circuit control carrier plate with antenna or chip. These modules are nested within each other and within the overall card body structure, allowing compact integration that reduces the impact of added complexity while maintaining enhanced security functionality.
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 card provides a visual reminder during data exchange, enhancing user awareness and security by preventing unauthorized use after transaction completion.
Implementation Method 1
The light-guiding module is disposed in the card body and corresponds in position to the light-emitting module. Light emitted from the light-emitting module is guided by the light-guiding module to the light-penetrable border portion of the card body.
Implementation Method 2
An oblique refraction portion is disposed on a surface of the light-penetrable border portion.

AI summary
An electronic card capable of light-emitting display includes a card body, electrical control module, light-emitting module and light-guiding module. The card body has a light-penetrable border portion having a surface on which an oblique refraction portion is disposed. The electrical control module is disposed in the card body and includes a circuit control carrier plate and a non-contact type radio-frequency antenna or a contact type communication chip. The light-emitting module is disposed in the card body and electrically connected to the circuit control carrier plate. The light-guiding module is disposed in the card body and corresponds in position to the light-emitting module. During personal data or transaction data exchange carried out with the card body, light emitted from the light-emitting module driven by the electrical control module is guided by the light-guiding module to the light-penetrable border portion, allowing the oblique refraction portion to increase display light brightness.
